Staged Minimally Invasive Plate Osteosynthesis of Distal Tibial Fractures: Sung Ki Park, Chang Wug Oh, Jong Keon Oh, Kyung Hoon Kim, Woo Kie Min, Byung Chul Park, Won Ju Jeong, Joo Chul Ihn; J Korean Fract Soc 2010;23(3):289-295. Published online July 31, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.3.289

PURPOSE
To assess the result of staged minimally invasive plate osteosynthesis (MIPO) for distal tibial fracture with an open wound or injured soft tissue.
MATERIALS AND METHODS
In 20 patients (mean age, 47.8 year-old) with distal tibial fractures, there were 4 type A fractures and 16 type C fractures based on the AO classification system. Eight of the 20 patients had open fractures. MIPO was performed on average 23.9 days after bridging external fixation. At the final follow-up, we assessed the radiological results of bone union and alignment. Functional results were also evaluated by measuring the degrees of ankle motion and the American Orthopedic Foot & Ankle Society (AOFAS) scores.
RESULTS
Seventeen of 20 cases (85%) achieved primary union at an average of 21.3 weeks. There were 3 cases of nonunion requiring a bone graft. The mean AOFAS score was 88.5 (range, 67~92) and the average range of ankle motion was 49.2degrees (plantarflexion: 37.4degrees, dorsiflexion: 11.8degrees). Complication included 2 cases of minor mal-alignment, 1 case of claw toe and 1 case of peroneal neuropathy. Patients over the age of 60 had lower functional results. Additional factors did not affect the final results.
CONCLUSION
Staged MIPO may achieve satisfactory results in distal tibial fractures with soft tissue compromise, decreasing deep infections and soft tissue complications.

Crescent Fracture-dislocation of Sacroiliac Joint: Affecting Factors of Operative Results: Hee Soo Kim, Chang Wug Oh, Poong Taek Kim, Young Soo Byun, Joo Woo Kim, Byung Chul Park, Woo Kie Min, Hyun Joo Lee; J Korean Fract Soc 2009;22(2):71-78. Published online April 30, 2009; DOI: https://doi.org/10.12671/jkfs.2009.22.2.71

Abstract PDF

PURPOSE
To assess the affecting factors of results after the operation of Crescent fracture-dislocation in sacro-iliac joint.
MATERIALS AND METHODS
In 19 patients (mean age, 47.4 year-old) of open reduction and internal fixation for Crescent fracture-dislocation, there were seven type I, 9 type II, and 3 type III fractures according to Day's classification. We assessed affecting factors of radiological and functional results, such as patients' ages, surgical approaches, the fixation extent of pelvic ring, and fracture patterns.
RESULTS
Seventeen of 19 cases united at 14.5 weeks in average, and 2 non-unions occurred with the fixation failure of posterior ring. Satisfactory results were 14 and 15 in radiological and functional evaluation, respectively. In complications, three cases of leg length discrepancy were from an imperfect reduction and two fixation failures. Surgical approach did not show any difference of results, but all cases of unsatisfactory reduction occurred from posterior ring fixation through the anterior approach. Fixation of both rings seemed to have satisfactory results, comparing to posterior ring only. Older patients over 60 year-old had more complications and a tendency to show an unsatisfactory result.
CONCLUSION
In operative treatment of Crescent fracture-dislocation of sacro-iliac joint, it is better to fix both anterior and posterior rings. But, caution is needed to prevent complications in old-aged patients.

Abstract PDF

PURPOSE
To assess the results of staged MIPO (Minimally Invasive Plate Osteosynthesis) for proximal tibial fractures with compromised soft tissue.
MATERIALS AND METHODS
Eighteen proximal tibial fractures (AO 41:9 cases, AO 42:9 cases) included this study. Ten were open fractures. After temporary external fixation until soft tissue healed (mean 27.3 days), MIPO was performed secondarily without bone graft. We assessed the bony union and knee function, and affecting factors of the results were investigated.
RESULTS
All fractures united at 20 weeks (range, 11~32) except 1 case. Mean range of knee flexion was 134.4degrees and mean IOWA knee score was 89.1. There were 2 superficial and 2 delayed deep infections from open fractures (grade II:1 case, grade III:3 cases), although they healed after implant removal. Open fractures seem to influence the infection rate. Otherwise, there was no related factor affecting the results.
CONCLUSION
MIPO after temporary external fixation can provide favorable results in proximal tibial fractures with soft tissue injuries, but attention of delayed infection should be paid in open fractures.

Bone Transport Over the Intramedullary Nail for Defects of Long Bone: Jae Young Roh, Chang Wug Oh, Jong Keon Oh, Hee Soo Kyung, Byung Chul Park, Woo Kie Min, Joon Woo Kim, Chang Hyun Cho; J Korean Fract Soc 2008;21(1):37-44. Published online January 31, 2008; DOI: https://doi.org/10.12671/jkfs.2008.21.1.37

Abstract PDF

PURPOSE
To evaluate the results of bone transport using external fixator over an intramedullary nail for defects of long bone.
MATERIALS AND METHODS
We treated 14 cases of bone defect after chronic osteomyelitis or trauma of tibia (12 cases) and femur (2 cases) using this method. The mean age of index procedure was 46.9 years, and all of them had follow-up study for a mean of 3 years. After the corticotomy and insertion of intramedullary nail, bone transport was done by external fixators. Then, the segment was moved and bone graft was done at docking site.
RESULTS
The mean transported amount was 5.8 cm, and the external fixator was removed after 141 days. The mean external fixation index was 25.6 days/cm. Primary union of distraction and docking site was achieved in all, but one had failure in union of docking site. According to the Mekhail's functional criteria, there were 5 excellent, 6 good, and 3 fair results. Among 15 complications, there were 2 major complications with residual sequelae, and they were 1 recurred osteomyelitis and 1 flexion contracture of knee.
CONCLUSION
Bone transport using external fixator over an intramedullary nail, can successfully solve defects of long bone. Since this method can remove external fixators earlier than the conventional method, it has fewer complications and makes patients to return to daily life earlier.

Comparison of Operative Methods between Retrograde and Antegrade Nailing for Ipsilateral Femoral Shaft and Neck Fracture: Chang Wug Oh, Jong Keon Oh, Woo Kie Min, Shin Yoon Kim, Seung Hoon Baek, Byung Chul Park, Hyung Soo Ahn, Tae Gong Kim; J Korean Fract Soc 2007;20(2):135-140. Published online April 30, 2007; DOI: https://doi.org/10.12671/jkfs.2007.20.2.135

Abstract PDF

PURPOSE
To compare retrospectively the antegrade and retrograde nailing in the management of ipsilateral femoral neck and shaft fractures.
MATERIALS AND METHODS
Thirty-two patients (thirty-three injuries) were included in this study. Mean age of patients was 38 years-old in the antegrade nailing group (16 injuries) and 44 years-old in the retrograde nailing group (17 injuries). We compared the union of fractures and complications between two groups, and investigated the influencing factors.
RESULTS
Femoral shaft fracture was united in 10 cases (63%) of antegrade group and 12 cases (71%) of retrograde group, at 28.2 and 27.3 weeks respectively. Nonunion was more prevalent in Winquist-Hansen III and IV (5 in antegrade nailing, 3 in retrograde nailing) than I and II. Femoral neck fracture was united with 1 case of nonunion in each group. Nonunion developed from Garden stage IV, but fractures of Garden stage I and II united regardless of methods.
CONCLUSION
In ipsilateral femoral neck and shaft fractures, the kinds of methods did not affect the results of shaft fractures. Minimally displaced neck fractures also were not influenced by kinds of methods, but retrograde nailing may have a benefit in fixing the displaced neck fractures

A Biomechanical Advantage of the Lengthening with an External Fixator Over an Intramedullary Nail: An Experimental Study in Saw Bones and Cadeveric Bones: Chang Wug Oh, Poong Taek Kim, Hae Ryong Song, Jong Keon Oh, Hyung Soo Ahn, Byung Chul Park, Byung Guk Min, Sung Ki Park, Young Heon Sohn; J Korean Fract Soc 2005;18(3):335-340. Published online July 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.3.335

Abstract PDF: PURPOSE
To know biomechanical differences in methods of limb lengthening between using monolateral external fixator and using external fixator over an intramedullary nail.
MATERIALS AND METHODS
In acryl rods, saw-bone, and cadeveric bone, we created two lengthening models of using monolateral external fixator and using external fixator over an intramedullary nail. The axial compression test was done on the site of osteotomy for lengthening. To fix the models, half pins of 5 mm in diameter and nails of 9 mm in diameter were used. Using MTS (Material Test System) machine, we evaluated the differences of axial stiffness according to the presence of an intramedullary nail or the numbers of half-pins which were fixed at each side of osteotomy.
RESULTS
Lengthening over an intramedullary nail, comparing to monolateral external fixator only, increased the axial stiffness by 1.1~1.2 times in acryl rods, 1.2~1.6 times in saw bones, and 15.6~15.9 times in cadeveric bones when the same numbers of half-pins were used. In saw bone and cadaveric bone, the group of two half pins in lengthening over an intramedullary nail was stiffer than the group of three pins in lengthening with monolateral external fixator.
CONCLUSION
In the distraction of the limb, the addition of an intramedullary nail may increase the axial stiffness of the frame of monolateral external fixator. In lengthening over an intramedullary nail, it is enough to distract the bone with fixing two half pins at each sides of osteotomy.

Double Plating of Proximal Tibial Fractures Using Minimally Invasive Percutaneous Osteosynthesis Technique: Chang Wug Oh, Jong Keon Oh, In Ho Jeon, Hee Soo Kyung, Il Hyung Park, Byung Chul Park, Woo Kie Min, Ji Ho Lee; J Korean Fract Soc 2005;18(3):250-255. Published online July 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.3.250

Abstract PDF

OBJECTIVES
To evaluate the results and its efficacy of double plating for proximal tibial fractures using minimally invasive percutaneous osteosynthesis (MIPO) technique. MATERIAL & METHODS: Twenty-three fractures, followed-up more than 1 year, were included in this retrospective study. There were 18 men and 5 women, and the mean age was 53.5 years-old. According to the AO-OTA classification, five were 41A, 13 were 41C, and 5 were 42. There were four open fractures (grade I- three, grade III A-one case). The plates were fixed on the medial and lateral sides of tibia with MIPO technique. Functional and radiographic results were evaluated by the modified Rasmussen system.
RESULTS
All fractures healed without bone graft, and the mean period for fracture healing was 19.3 weeks (range, 10~32 weeks). All other patients had excellent or good clinical or radiological results, except for two patients of a fair clinical result after a combined injury. Complications included one case of shortening (1 cm) and two cases of mal-alignments (varus less than 10 degrees). There was one case of superficial infection, but no patient showed deep infection.
CONCLUSION
Double plating using MIPO technique can provide favorable results in the treatment of proximal tibial fractures.

Internal Bone Transport in the Management of Tibial Bone Defects: Chang Wug Oh, Woo Kie Min, Hee Soo Kyung, Il Hyung Park, In Ho Jeon, Byung Chul Park, Poong Taek Kim, Young Heon Sohn; J Korean Fract Soc 2005;18(1):36-42. Published online January 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.1.36

Abstract PDF

PURPOSE
To retrospectively review the results of internal bone transport in the management of tibial bone defect using ilizarov fixator.
MATERIALS AND METHODS
We treated 39 cases of tibial bone defect (16 of traumatic bone loss, 23 after treatment of osteomyelitis). The mean age of index procedure was 33.8 years (range, 13~66 years), and all of them had follow-up study for a mean of 3.5 years (range, 1.6~8 years). The mean transported amount was 6.3 cm (range, 2.7~20 cm), and the external fixator was removed after 345 days (range, 120~700 days). The mean external fixation index was 60.3 days/cm (range, 13.1~121.3 days/cm).
RESULTS
Primary union of distraction and docking site was achieved in all, but two patients had failure in union of docking site. Functional results showed 6 excellent, 19 good, 10 fair, and 4 fair. The patients under age 20 showed better functional outcomes than the others. Among 73 complications (incidence, 1.87 cases/ patient), 27 of major complications with residual sequelae occurred in 20 patients. The residual sequelae were more common in the patients who had the concomitant injuries in the same leg.
CONCLUSION
Internal bone transport can solve the large amount of tibial bone defect. However, the complications are not uncommon, which might be related to the concomitant injures in the same leg.

Operative Treatment of Type III Coronoid Process Fractures: In Ho Jeon, Woo Kie Min, Chang Wug Oh, Hee Soo Kyung, Byung Chul Park, Poong Taek Kim, Joo Chul Ihn, Jung Yup Lee; J Korean Fract Soc 2004;17(4):338-344. Published online October 31, 2004; DOI: https://doi.org/10.12671/jkfs.2004.17.4.338

Abstract PDF: PURPOSE
To review the clinical results of eight cases of typeIII coronoid process fractures which were treated operatively.
MATERIALS AND METHODS
Eight patients with coronoid type III fracture were reviewed retrospectively. All were men with an average age of 33. There were three isolated fractures, two elbow dislocations, two radial head and neck fractures, and one medial collateral ligament rupture. Open reduction and internal fixation through anterior approach with canulated screws was used. The patients were followed up for a mean of 31 months (24 to 60).
RESULTS
Average active elbow joint motion at the most recent follow up was 105degrees. The average Mayo Elbow Performance Score was 76.9 (50 to 95). There was one excellent result, four good, two fair, and one poor.
CONCLUSION
Early open reduction and stable internal fixation provided a reliable method for the treatment of type III coronoid process fractures. Any associated ligament injuries to the elbow and fracture comminution were considered as important prognostic factors.

Treatment of Proximal Shaft Fracture of Tibia with Intramedullary Nail: Analysis According to AO Classification and the Poller Screw: Chang Wug Oh, Sung Jung Kim, In Ho Jeon, Hee Soo Kyung, Byung Chul Park, Joo Chul Ihn, Kyung Hoon Kim, Yun Kee Woo; J Korean Fract Soc 2004;17(2):133-137. Published online April 30, 2004; DOI: https://doi.org/10.12671/jkfs.2004.17.2.133

Abstract PDF

PURPOSE
This was a retrospective study to evaluate the results of intramedullary nailing in proximal shaft fracture of tibia. We analyzed those results according to AO classification and Poller screw.
MATERIALS AND METHODS
Thirty-three proximal tibial shaft fractures (32 patients) were followed for more than one year. In AO classification, there were 6 cases of type A, 14 cases of type B, and 13 cases of type C. We used Poller screws in 14 operations. We evaluated translation, angulation and nonunion after surgeries.
RESULTS
Twenty-eight cases (85%) were united primarily, but nonunions occurred in 5 cases. Malalignment (angulation>5degree or translation>5 mm) was found in 14 cases (42%). In Poller screw used and non-used groups, the malalignment was respectively showed in 2 cases (14%) and 12 cases (63%). According to AO classification, nonunion was found in only type B with 5 cases (36%).
CONCLUSION
Intramedullary nailing of proximal shaft fracture of tibia showed relatively lower rate of primary union. Especially, when initial fractures have a butterfly fragment, it showed the higher rate of nonunion. Moreover, the malalignment rate was relatively higher, yet it is possible to reduce the rate of malalignment by using Poller screw.

Published online October 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.4.474

Abstract PDF

PURPOSE
We retrospectively reviewed the outcomes and advantages of minimal invasive plating osteosynthesis (MIPO) technique as a new treatment of distal femoral fractures.
MATERIALS AND METHODS
Sixteen supracondylar femoral fractures (15 patients) were treated by MIPO technique and evaluated radiologically and functionally after minimal 1 year follow-up (average; 22 months, range; 13~42 months). There were 9 women and 6 men with a mean age of 46 years old (range 35 to 64 years). Seven fractures were extended into knee joints (AO/OTA type C), and 9 were extraarticular (AO/OTA type A). Five cases were open fractures (type I; 2, type II; 3) according to the Gustilo-Anderson classification. After minimal lateral parapatellar incision and accurate reduction of intra-articular fractures, the supracondylar fractures were fixed by percuatneous plating method without exposure of fracture area. Neer scoring was used for functional evaluation of knee.
RESULT
At a mean of 17 weeks (range 14 to 22), most fractures united without secondary procedures. One case of nonunion had the procedure of bone graft, but there were no other complications including shortening over 1 cm, mal-alignment over 10 degrees, or deep infections. All the cases had good or excellent knee function, and the average range of knee motion was 120.6 degrees.
CONCLUSION
MIPO technique is a worthwhile method of managing distal femoral fractures with good unions and functional recovery.

Treatment of Nonunion in the Long Bone with Low Intensity Pulsed Ultrasound (LIPUS) and LASER: In Ho Jeon, Chang Wug Oh, Sung Jung Kim, Hee Soo Kyung, Il Hyung Park, Byung Chul Park, Joo Chul Ihn, Jun Young Yeo; J Korean Soc Fract 2003;16(2):177-185. Published online April 30, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.2.177

Abstract PDF: PURPOSE
Low-intensity, pulsed ultrasound (LIPUS) has demonstrated a stimulation and acceleration of the normal fracture-repair process in cellular bases as well in animal and human models. In this study, the adjunctive effect of LIPUS and LASER was investigated in established nonunion of the long bones.
MATERIALS AND METHODS
Study group consisted of eight patients to whom conventional bone graft and adjunctive LIPUS and LASER was applied. On the other hand, eight patients in the control group underwent bone graft only. Eleven men and five women were included in this study and the average age of the patients was 41.7 years (range, 19~62 years). Six of the tibias and ten of the femurs met the criteria for established nonunion. The average fracture age, the post-fracture period before the start of LIPUS/LASER treatment, was 502 days.
RESULTS
Seven of the ten nonunions who were treated by LIPUS and LASER healed completely in an average treatment time of 141 days (range, 101~202 days) and otherwise, in control group, five of the eight nonunions healed completely, in 240 days (range, 183~283 days).
CONCLUSION
This clinical study showed a positive effect of LIPUS and LASER on the rate of osseous repair, especially accelerated time to initial callus cortical bridging compared to that of conventional treatment.

Treatment of femoral diaphyseal fractures in children: Comparison between conservative treatment and retrograde flexible intramedullary nailing: Chang Wug Oh, Byung Chul Park, Joo Chul Ihn, Hyung Tae Soh, Seung Hoon Baek; J Korean Soc Fract 2002;15(2):292-298. Published online April 30, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.2.292

Abstract PDF: PURPOSE
To compare clinical outcomes and complications between pediatric patients with femoral shaft fracture who had undergone conservative treatment and retrograde flexible intramedullary nailing.
MATERIALS AND METHODS
51 cases of 46 pediatric patients who had femoral shaft fracture were retrospectively studied. Hip spica cast was applied 3~6 weeks after traction in 24 cases of conservative treatment group and closed reduction and internal fixation with flexible nails were performed in 27 cases.
RESULT
Neither pain, limitation of joint motion, nor nonunion was reported in both groups. In radiologic evaluation, 4 cases of angulation more than 10 degrees were observed in conservative treatment group and none of surgical treatment group. In leg length discrepancy(LLD) over 10 mm, there was none in surgical treatment group, but 4 cases were seen in the conservative group. Two cases of limping were observed only in the conservative group. Mean time to weight bearing was earlier in surgical treatment group(7.5 weeks) than that in the conservative group(10.8 weeks).
CONCLUSION
As treatment of pediatric femoral shaft fracture, retrograde flexible intramedullary nailing had less complications such as LLD and angulation and enabled earlier rehabilitation than conservative treatment.

Effect of injected calcium-sulfate on the consolidation of distraction osteogenesis in rabbit model: Chang Wug Oh, Poong Taek Kim, Byung Chul Park, Il Hyung Park, Hee Soo Kyung, Seung Hoon Baek; J Korean Soc Fract 2002;15(2):271-277. Published online April 30, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.2.271

Abstract PDF: PURPOSE
To investigate whether injection of calcium sulfate salt powder could be used to facilitate consolidation of early & fast distraction osteogenesis.
MATERIALS AND METHODS
Group I was experimental group and Groups II and III were controls. After 3 days of latency period, a small distractor was distracted for a total of 8 mm for 4 days. Calcium sulfate salt powder suspended in carboxymethylcellulose(CMC) solution was injected, whereas CMC media alone was injected in one control group and without intervention in the other control group. Plain radiographs were taken on every weeks. We assesed the bone mineral density(BMD) at 3 and 6 weeks and %BMD was calculated. The rabbits were sacrificed at 6 weeks for histologic examination.
RESULTS
In radiography, the distracted area was consolidated in the experimental group but not in control groups. The % BMD of the experimental group was significantly greater than that of control groups at 6 weeks(p<0.01). In histologic examination, greater amount of newly formed bone was noted in the distraction zone of the experimental group, compared to two control groups.
CONCLUSION
Implantation of calcium sulfate powder can accelerate consolidation in distraction osteogenesis in rabbits.

Selective treatment for completely displaced supracondylar fractures of the humerus in children: Chang Wug Oh, Byung Chul Park, Young Woo Kim; J Korean Soc Fract 2001;14(3):534-540. Published online July 31, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.3.534

Abstract PDF: PURPOSE
This retrospective study was performed to know the clinical results after closed reduction and open reduction for completely displaced supracondylar fractures of distal humerus in children.
MATERIALS AND METHODS
Twenty-eight cases of this injury at the mean age of 6.4 (range 21- 138 months), have been followed up over the minimum of one year. The types according to the position of displacement were 15 in posteromedial, and 13 in posterolateral displacement. There were 4 cases of associated nerve palsies (3;median, 1; radial). We tried the closed reduction (17 cases), but open reduction (11 cases) was indicated in irreducible cases with or without severe swelling. Then, the fractures were stabilized by percutaneous K-wires with lateral (23 cases) or cross pinning (5 cases). The differences of Baumann's angle, humero-ulnar angle, and elbow motion to uninjured side were calculated, and Flynn's criteria was used for evaluation.
RESULTS
All fractures were united without any infection or soft tissue compromise. The symptoms of injured nerve recovered within 8 weeks. According to Flynn's cirteria, results were excellent in eleven, good in 12, fair in 2, and poor in 3. The rates of satisfactory results over good were similiar between closed and open reduction, and the other factors including age and type of displacement were not meaningful. The mean Baumann's angle was 8.7 in closed and 6.6 in open reduction group. None of the patients showed restricted elbow motion above 10 degrees, even in 3 cases of hypertrophic scars in the group of open reduction.
CONCLUSION
The selective use of open reduction in completely displced supracondylar fractures of distal humerus in children, would show results as good as closed reduction.

Retrograde Flexible Intramedullary Nailing of Pediatric Femur Fractures: Chang Wug Oh, Byung Chul Park, Hyung Jin Park; J Korean Soc Fract 2001;14(2):272-277. Published online April 30, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.2.272

Abstract PDF

PURPOSE
This study was designed to evaluate the clinical effectiveness including bone union, leg length discrepancy, after retrograde flexible intramedullary nailing for pediatric femoral fractures. MATERIAL AND METHOD: Nineteen cases (18 patients) with femur fracture at the age of 4 to 10 years (mean age 6.7) have been followed up over the minimum of one year. Under imaging intensifier, the fracture was temporarily reduced with manual traction, and 1 or 2 flexible nails were inserted at medial and lateral side of distal femur above the distal epiphysis. After two weeks of immobilization with long leg splint, joint motion was permitted. At 6-8 weeks, partial weight bearing was permitted, and at 10- 12 weeks, full weight bearing was permitted.
RESULTS
Time to radiologic union averaged 10.9 weeks. Limb length discrepancy ranged from 7mm of shortening to 6mm of overgrowth(mean ; 1.1mm of overgrowth), but there was no severe limb length discrepancy over 10mm. As another complications, there were one case of limited motion of knee joint and one case of broken nail.
CONCLUSION
We found that retrograde flexible intramedullary nailing is a safe, effective treatment for acute femoral shaft fractures in skeletally immature patients.

Bicondylar Tibial Plateau Fractures Treated with Hybrid-Ring External Fixator: Chang Wug Oh, Hee Soo Kyung, Joo Chul Ihn, Byung Chul Park, Young Chul Choi; J Korean Soc Fract 2000;13(4):877-883. Published online October 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.4.877

Abstract PDF

PURPOSE
This study was designed to evaluate the indirect reduction or limited internal fixation with hybrid external fixation for bicondylar fractures of proximal tibia. MATERIALS & METHODS: Twenty-two cases (mean age; 49) proximal tibial fractures have been treated, including 7, type V and 15, type VI. After reconstruction of articular surface, the hybrid fixation was applied at the condyle and shaft with or without limited internal fixation by cannulated screw or one-third plate. We permitted early ROM exercise of knee and partial weight-bearing about 4 weeks after operation.
RESULTS
Time to union averaged 15.6 weeeks(range ; 11-20 weeks). There were 4 cases of nonunion including three cases of early bone graft for severe comminution and one infection. Functional scoring revealed 5 excellent, 12 good, 3 fair and 2 poor results. 18 out of 22 cases had good or excellent result in anatomical grading. The mean range of knee motion was 116 degrees(from 4.1 to 120 degrees). In complications, there were two cases of malunion, one deep infection, and one pin-site infection, but soft tissue compromise such as skin necrosis was not happened.
CONCLUSION
The indirect reduction or limited internal fixation with hybrid external fixation for bicondylar fractures of proximal tibia have advantages of anatomic, stable fixation, early mobilization and less soft tissue dissection, so good results of knee function can be accomplished.

Effect of Insertion of Bone Graft Substitutes on Consolidation of Distracted Callus: Changes of Radiography & Bone Mineral Density in the Tibia of Rabbits: Chang Wug Oh, Poong Taek Kim, Byung Chul Park, Hae Ryong Song, Il Hyung Park, Jun Ho Baek, Hyung Jin Park; J Korean Soc Fract 2000;13(4):687-695. Published online October 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.4.687

Abstract PDF: PURPOSE
This study was designed to know the effect of calcium-sulfate and xenograft on the distracted callus after lengthening.
MATERIALS AND METHODS
We had operation of subperiosteal osteotomy and external fixation on the tibial diaphysis of young New Zealand White rabbits(2.0-2.5kg); after 5 days of latency period, 7 mm(1mm/day, 2 times/day) of tibial lengthening was reached in a week. At 1 week after lengthening, the 1st experimental group of 7 rabbits received a pellet of calcium sulfate(Osteoset , Wright medical, USA) in the distraction gap, and the 2nd experimental group of 7 rabbits received 5mm2 of xenogrfat(Lubboc ) in the distraction gap. But, the control group of 7 rabbits did not receive any of above materials. We compared three groups with the changes of radiographic findings at every week and bone mineral ratio(DEXA) at every two weeks.
RESULTS
The time to complete consolidation of distraction callus of both experimental group(calcium sulfate;14 weeks, xenograft; 15.4 weeks) was shorter than that of control group(16.9 weeks) in radiographic findings. Maximum value of bone mineral ratio of distraction callus was higher and the time to reach the highest value was also shortened in the both experimental group compared to control group.
CONCLUSION
By use of bone substitutes as like calcium sulfate or xenograft in the distraction callus with external fixator, it may be possible to shorten the consolidation period and the fixator-wearing period.

Abstract PDF

PURPOSE
: To evaluate the results of the treatment of distal tibial fracture using ring or hybrid ring external fixator and to compare the results according to the influencing factors.
MATERIALS AND METHODS
: The authors analized 30 patients, 31 cases of distal tibial fracture who were treated by Ilizarov ring external fixator or hybrid ring external fixator at our hospital from May 1996 to August 1998 and were followed up over 1 year. The type of distal tibial fractrue were classified according to AO group, type A was 7 cases, and type C was 24(C1:5, C2:4, C3:15)cases. Restoration of articular surface of the distal tibia was performed through closed method or minimal invasive technique by minimal internal fixation with K-wire or screw. Then fixation of th distal tibia was done by ring external with multiple transfixing wire. Connection to the tibial shaft was done by Ilizarov ring external fixator(15 cases), or mono-external fixator(Dyna-Extor, 16 cases).
RESULTS
: By Tornetta's assessment of functional results, excellent was 5, good 19, fair 4 and poor 3cases. According to AO classification, the functional results of type A, 7cases were all above good results, among 24 cases of type C, 4cases of C1, 2 cases of C2, and 11 cases of C3 were above good results and there was no statistical difference between the results and the fracture type(P=0.024). One of 3 cases of poor functional results was open type C3 fracture and was complicated with osteomyelitis and refracture, and others two cases type C2 fracture which were complicated with malunion.
CONCLUSION
: The authors had a good results without soft tissue complication after the treatment of distal tibial fracture patients by Ilizarov ring external fixator or hybrid ring external fixator.

Arterial Injuries associated with Fractures or Dislocations around the Knee: Chang Wug Oh, Joo Chul Ihn, Byung Chul Park, Il Hyung Park, Shin Yoon Kim, Hee Soo Kim; J Korean Soc Fract 1999;12(4):865-871. Published online October 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.4.865

Abstract PDF: The purpose of this article is to delineate factors important in successful management and subsequent extremity function of the patient with arterial injury associated with fractures or dislocations around the knee. We reviewed 25 cases of arterial injury associated with fractures or dislocations around the knee which were treated at our hospital between 1994 and 1998. As long term results, the salvage rate of the lower limb was related to the extent of the soft tissue damage and the severity of infection, but there was no statistical difference according to the method of vascular surgery(p=0.645). Compared with the salvage rate of the lower limb according to the length of time from injury to vascular reanastomosis, there was no statistical difference between two groups of the patients who were operated within 12 hours and were operated during the time between 12 hours and 24 hours(p=0.084). In view of whether open or closed fractures were combined, 1 I cases(58%) among 19 cases of open fractures and 5 cases(83%) among S cases of close(1 fractures were able to salvage the lower limb, so it could contributes to the sdlvdge rate of the limb. Finally 16 cases(64%) among total 25 cases were able to salvage the lower limb, and its functional outcome was like followings : excellent results were found in 6 cases, fair results in 8 cases, poor results in 2 cases, and amputation in 9 cases(36%). In case of amputation, 3 cases were primarily amputated and 6 cases were amputated secondary to vascular surgery . As long term results, whether open or closed fractures were combined, the teverity of the infection and the extent of the soft tissue necrosis were the factors influencing on the falvage rate of the lower limb. Other factors, such as the difference of ischemic time within 24 hours interval, the site and the method of management of the fractures and the vascular injuries and whether fasciotomy was performed or not were not important factors influencing on the salvage rate of the lower limb.

Published online October 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.4.824

Abstract PDF: The purpose of this paper was to evaluate the results of the femoral shaft fractures by reamed Russell-Taylor intramedullary nailing in the viewpoint of union time and complications. We reviewed 59 femoral shaft fractures. According to the type of fractures(Winquist-Hansen classification), average union time were 20.1 and 23.5 weeks in type 1, 2 and 3, 4, and nonunion rates were 12.5% and 10.5% in type 1, 2 and 3, 4. According to the level of fractures, average union time were 19.9, 20.3, 23.4 weeks in proximal, middle and distal fractures, and nonunion rates were 6.7%, 8.8%, 30% in proximal, middle and distal fractures. According to the reduction techniques, average union time were 20.0 and 21.5 weeks in closed and open reduction, and nonunion rates were 5.9% and 20.O% in closed and open reduction. According to the Methods of interlocking screw fixation, average union time were 19.3 and 20.7 weeks in dynamic and static fixation, and nonunion rates were 25% and 9.8% in dynamic and static fixation. There was no significant differences in averdge union time between closed and open fracture group, closed and open reduction group, and dynamic and static fixation group. There was significant differences in union time between simple and complex, comminuted fractures(P<0.05), and between distal and proximal, middle fractures(P<0.05). Also there was significant differences in nonunion rate between fracture reduced with closed and open technique(P<0.05). In conclusion, reamed Rustell-Taylor intramedullary nailing can be a uheful treatment modality in femoral shaft fracture if closed reduction is available. However, there was high complication rate including failure of screw, varut deformity, delayed union time in distal femoral shaft fractures. In this situation, we should consider other treatment method.

Abstract PDF: Infected nonunion developed after open reduction and internal fixation is one of the serious complications among the treatments of fracture of long bone. It is very difficult to eliminate the infection, to correct the deformity and defect at the same time obtaining union. All six cases were male, the average of age was 34 years old from 21 to 49. Five cases were closed fracture and one was open fracture. For the primary internal implant, five cases were plate and one was intramedullary nail. About the 6 cases of infected nonunion of femur from June, 1994 to October, 1996, we performed the following procedure : after removal of internal fixation, extensive debridememt, complete sequestrectomy, firm fixation with Ilizarov external fixator, compression at fracture site and early autogenous cancellous bone graft. We obtained following results : 1. The average duration of infection was 7.8 months, average duration of bone union was 5.8 months. Average duration of follow-up was 17.5 months. 2. The average shortening of leg was 1.4cm. 3. According to classification of Paley and Catagni, the bone results were excellent in all cases, functional results were excellent in 4 cases and fair in 2 cases. 4. In conclusion, firm fixation with Ilizarov fixator, sequestrectomy, early autogenous cancellous bone graft and compression is one of the good treatment modalities of infected nonunion of the femur.

Treatment of Infected Nonunion with Bone Defect with Ilizarov Lenthening apparatus: Joo Chul Ihn, Byung Chul Park, Il Hyung Park, Hee Soo Kyung, Chang Wug Oh, Jin Hum Cho; J Korean Soc Fract 1998;11(1):91-99. Published online January 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.1.91

Abstract PDF: From June 1993 to May 1997, 12 patients aged from 13 to 41 years were treated for infected nonunion with bone defect by the Ilizarov technique. Of 12 cases, 9 cases were tibia and 3 cases were femur. The cuases of nonunion were open comminuted fractures with initial bone loss and bone defect after removal of sequestrum. Infection was managed by radical resection of the infected necrotic bone and insertion of antibiotics mixed cement beads. Bony defects were gradually closed by the Ilizarov's internal bone transport technique, and final equalization of leg length inequality was achieved by means of external lenghthening technique. Corticotomies were performed at the proximal level(7), at the distal level(5). The average optained length averaged 4.8cm in length and healing index averaged 67.4days/cm According to paley and Catagni's callification bony and functional results were either excellent or good execpt I case (nonunion, poor bony result). The complications (devided by paley to 3 categories: problems, obstacles, complications) were pin tract infecton(8), pain(5), mild flexion contracture of joint(1), delayed consolidation(3), soft tissue impingement(2), joint stiffness(3) and nonunion(1). We concluded that Ilizarov techinque was very effective for treatment of infected nonunion with bone defect and soft tissue defect.

Structural Study of Proximal femur in the Elderly Femoral Neck & Trochanteric Fracture: Byung Chul Park, Chang Wug Oh, Seung Hoon Oh; J Korean Soc Fract 1998;11(1):175-180. Published online January 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.1.175

Abstract PDF: The factors that determine whether a proximal femoral fracture is neck or trochanteric area are a matter of controversy. So we studied the BMD(bone mineral density) and the morphology of the contralateral femur in subcapital fracture and intertrochanteric fracture(Boyd - Griffin Type I,II). The bone density of femoral neck, Ward's triangle and trochanteric region was measured by dual energy X-ray absortiometry(DEXA) in 41 patients with femoral neck fracture value and fracture type in same patients, we calculate the femoral neck length from the plain X-ray film. The results were as follows. 1. The ratio of BMD in the neck and trochanter area was higher in the trochanter fracture group. 2. The level of BMD of the trochanter fracture group was lower than the neck fracture group in all opints of measurement. 3. In the measurement of femoral neck length at plain X-ray film, the neck length of trochanter fracture group was longer than the neck fracture group. It may be that difference in BMD and femoral neck length is related to the site at which a proximal femoral fracture occurs.

Comparison of the Treatment of Displaced Extension Type Supracondylar Fractures of the Humerus in Children: Joo Chul Ihn, Byung Chul Park, Hee Su Kyung, Chang Wug Oh, Hak Su Kim; J Korean Soc Fract 1997;10(1):203-210. Published online January 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.1.203

Abstract PDF: The treatment of supracondylar fracture of humerus in children has so many pitfalls as to be once called - supracondylar dilemma -. The authors analyzed the follow up results of 53 displaced extension type supracondylar fractures treated by closed reduction and cast, closed reduction and percutaneous pinning, skeletal traction and open reduction from 1993 to 1995. The following results were obtained : 1. Closed reduction and percutaneous pinning produced the best radiographic and clinical result by Flynns criteria when compared to other methods. 2. No difference in radiographical stability was found between percutaneous pinning with one medial and one lateral pin as opposed to two lateral pins. 3. There was a strong correlation between the change in Baumanns angle and the carrying angle(p=0.03).

Treatment of Intertrochanteric Fractures using Gamma Nail: Joo Chul Ihn, Byung Chul Park, Sin Yoon Kim, Hyung Soo Ahn; J Korean Soc Fract 1994;7(2):588-596. Published online November 30, 1994; DOI: https://doi.org/10.12671/jksf.1994.7.2.588

Abstract PDF

Surgical fixation, early weight bearing and bony union remain a challange in the treatment of intertrochanteric femur fractures, especially if the fractures are comminuted or unstable. We have experienced 18 cases of intertrochanteric femur fracture that were treated using Asian Gamma nails(Gamma AP) in Kyungpook National University Hospital in period from Feb. 1993 to Oct. 1993. Early full weight bearing was encouraged and this seemed to be beneficial for old patients. All fractures were healed securely and many patients(15/18) could be painless ambulatory regardless of fracture configuration(9 fractures classified as unstable). Major complications included screw cut-out(2 cases), lateral cortical fracture(1 cases) and delayed union(1 case). In this early experience, the Gamma nail appears to be useful internal fixator for intertrochanteric femur fractures and it allows early ambulation regardless of the fracture configuration with excellent clinical results.

A Clinical Study of the Ankle Fracture with Diastnsis: Ik Dong Kim, Jo Chul Ihn, Pong Tnk Kim, Byung Chul Park, Young Goo Lyu, Il Hyung Park, Chang Hyuk Choi; J Korean Soc Fract 1992;5(2):253-259. Published online November 30, 1992; DOI: https://doi.org/10.12671/jksf.1992.5.2.253

Abstract PDF: The ankle fracture with diastasls of distal tibiofibular joint is caused by an axial loading force with concomitant external rotation and associated with severe ankle fracture in addition to talai subluxation due to rupture of the distal tibiofibular syndesmosis. In order to restore the normal ankle mortise, operative anatomical reduction and temporary stabilization of the syndesmosis is mostily required until early ligament healing is present. Twelve cases among ninety-six cases of the ankle fracture were associated with diastasis and treated in the Department of Orthopedic Surgery, Kyungpook National University Hospital during the period from January, 1988 to May, 1991. We analysed these cases according to injury mechanism, radiographic criterion, the patterns of associated medial and lateral injury and treatment result. The results obtained were as follows; 1. The incidence of trauma was most frequent in 5th decade(5 cases). 2. Diastasls was produced by 3 mechanism according to Lauge-Hansen classification : (pronalion-external rotation : 7, Suplnatlon-external rotation : 3, pronation-Abduction;2). 3. All were associated with fibular fracture : proximal fibular fracture was most common (7cases). 4. All had disruption of the medial structures (medial ligament rupture 3, medial malleolusfracture 9). 5. Although the cases were small, there seems no significant differences between transfixation group and unfixation group when accurate anatomical restoration of the distal tibiofibular syndesmosis was achieved.
