Published online July 31, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.3.303

PURPOSE
To evaluate the surgical outcomes of open reduction and internal fixation of AO calcaneal plate in displaced intra-articular fractures of the calcaneus.
MATERIALS AND METHODS
From January 2004 to July 2007, 25 patients with 27 displaced intra-articular calcaneal fractures were treated by open reduction and internal fixation using the AO calcaneal plate. Preoperative, postoperative evaluations and a follow-up after 1 year were done radiologically by the Bohler angle, Gissane angle, heel height and width among all patients. Their functional status was assessed by means of the Maryland foot score.
RESULTS
The mean Bohler angle, Gissane angle, heel height and width were restored comparing with preoperative data. However, in Sanders type IV, some losses of reduction occurred at 1 year follow-up (p<0.05). The mean Maryland foot scores were 85 points in type II, 82 points in type III and 63 points in type IV. Sanders types significantly affected the clinical results (p<0.05).
CONCLUSION
The AO calcaneal plate fixation using extensile L-shpaed lateral approach shows satisfactory radiologic and clinical results in the treatment of displaced intra-articular calcaneal fractures.

Abstract PDF

PURPOSE
To evaluate functions of the elbow joint according to surgical approach, time to exercise, and type of fracture after surgical treatment for the intra-articular comminuted fracture of the distal humerus.
MATERIALS AND METHODS
27 patients with the intra-articular comminuted fractures of the distal humerus underwent surgery from March, 2000 to January, 2007. We investigated the surgical approach, time for union, time to exercise and age. We also evaluated postoperative functions of the elbow joint according to the flexion contracture, the range of motion and the Mayo elbow performance score.
RESULTS
The average follow-up period was 37 months and the average time for union was 14 weeks. The average range of flexion was 115 degrees, the average flexion contracture was 10 degrees, and the Mayo elbow performance score with average value of 85 point showed good clinical results. There were no statistically significant differences in functions of the elbow joint according to the operative method and age. However, patients with early postoperative exercise within 6 days showed statistically better outcomes than patients with postoperative exercise after 7 days. Type C1, 2 fractures showed statistically better results than the type C3 fracture.
CONCLUSION
Stable fixation and early exercise are required to prevent postoperative complications and restore functions of the elbow joint with an intra-articular comminuted fracture of the distal humerus.

Cause and Treatment of the Nonunion of Femoral Shaft Fracture after Interlocking Intramedullary Nailing: Sung Soo Kim, Sung Keun Sohn, Chul Hong Kim, Myung Jin Lee, Lih Wang; J Korean Fract Soc 2007;20(2):141-148. Published online April 30, 2007; DOI: https://doi.org/10.12671/jkfs.2007.20.2.141

Abstract PDF

PURPOSE
To analyze the causes and the clinical results of treatment for the nonunion of femur shaft fractures that occurred after interlocking intramedullary nail fixation.
MATERIALS AND METHODS
We reviewed 19 cases of aseptic nonunion of femur shaft fracture in 174 patients after interlocking IM nailing from March 1999 to February 2004 and followed up for more than one year. First we investigated the factors causing nonunion. For operative options, two methods about exchange nailing and exchange nailing with bone graft were performed. Finally clinical results were analyzed with bone union rate by treatment methods and compared with the nonunion factors statistically.
RESULTS
According to the causes and types of nonunion, we performed larger IM nail change in 10 cases and IM nail change with bone graft in 9 cases. Bone union was achieved in all cases. Average bone union period were 18.5 weeks in exchange group and 16.1 weeks in exchange with bone graft group. There are significant difference between treatment methods statistically (p<0.05). Compared with the nonunion factors, initial open fracture and smoking groups showed late union rate statistically.
CONCLUSION
Based on our analysis, IM nail change is a useful method for nonunion after initial IM nailing in femoral shaft fracture, and additional bone graft that according to the radiologic pattern and stability, especially the fracture gap is also a useful option for nonunion treatment.

Analysis of Failures of Union of the Intertrochanteric Femoral Fractures: Sung Soo Kim, Sung Keun Sohn, Myung Jin Lee, Min Soo Kang, Sang Kook Kim; J Korean Soc Fract 2003;16(4):456-464. Published online October 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.4.456

Abstract PDF

PURPOSE
The purpose of this study was to analyze the factors influencing the failure of union in the intertrochanteric femoral fractures.
MATERIALS AND METHODS
Authors divided the patients treated with lag screws into two groups, 9 cases of the non-union group and 46 cases of the union group. And analyzed the preoperative, intraoperative and postoperative factors influencing the union.
RESULTS
Age, displacement in AP film after surgery, displacement of lesser trochanter after surgery, superior or anterior position of lag screw, displacement of lag screw and change of neck-shaft angle were significantly higher in the non-union group. Displacement in AP radiograph after surgery and displacement of lag screw were two significant factors by multivariate logistic regression analysis.
CONCLUSION
In case of intertrochanteric fracture treated with lag screw, the probabilities of union failure are increased when the displacement is more than 5 mm in AP plane postoperatively and the sliding of lag screw is more than 10 mm in follow-up.

Treatment of Ipsilateral Femur and Tibia Fractures: Sung Keun Sohn, Kyung Taek Kim, Byeong Hwan Kim, Bum Ho Jung, Kyung Sik Hwang; J Korean Soc Fract 2000;13(4):837-846. Published online October 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.4.837

Abstract PDF

PURPOSE
Searching for the most excellent outcome of ipsilateral fractures of femur and tibia according to the treatment methods and the combined injuries which occasionally neglected.
MATERIALS AND METHODS
We reviewed thirty cases of ipsilateral fractures of the femur and tibia, treated at the orthopaedic department of the Dong-A university hospital between February 1991 and May 1999. Children under 10 years old, treated by conservative methods were excluded in this study. Average follow-up period was 23.2 months(range, 5 to 44 months) and mean age was 34.7 years old(range, 16 to 58 years).
RESULTS
According to the measurement of the Karlstrom and Olerud, range of motion of the ipsilateral knee joint and bony union time, intramedullary nailing was the treatment of choice for both femur and tibia fracures except limited by open wound and fracture level and types(14 cases, 47%). The ipsilateral knee ligaments injury was the most common combined injury which neglected at initial trauma(8 cases, 27%).
CONCLUSION
By intramedullary nailing, the patients with ipsilateral fractures of femur and tibia could achieve early weight bearing ambulation and ipsilateral knee joint excercise, and showed the most excellent outcome. After fixation of both femur and tibia fractures, by physical examination and arthroscopic examination of ipsilateral knee joint we could detect and treat the ipsilateral knee ligaments injuries, which occasionally neglected.

Abstract PDF

PURPOSE
: To evaluate the results of operative treatment for intercondylar fracture of the distal humerus in adults.
MATERIALS AND METHODS
: From February 1994 to June 1998, 15 patients with more than one year follow-up periods were treated by operative method at Sun General Hospital. 12 of them were treated by open reduction and internal fixation(dual plate for 8, screw & K-wire for 4) and 3 of them by open reduction & Ilizarov fixation. Open or closed fracture and AO classification of fracture were considerd as a prognostic factor. The functional results were analyzed by Jupiter's critera.
RESULTS
: There were 2 excellent, 2 good in C1 type, one excellent, 2 good, one fair and 2 poor in C2 type, and one excellent, 2 good, 2 poor in C3 type. And there were one good and one poor in 2 open fractures and 4 excellent, 5 good, one fair and 3 poor in closed fractures. The average range of motion of the elbow joint was 85 degrees(30 degrees-115 degrees). Overall results show excellent and good in 67%(10 of 15) and poor in 27%(4 of 15).
CONCLUSION
: It's not easy to get satisfactory results in treatment for intercondylar fracture of the distal humerus We suggest that more efforts are needed to get anatomical reduction, rigid internal fixation and early joint motion in interconylar fracture of the distal humerus.

Volar Perilunate Dislocation: A case report: Sung Soo Kim, Sung Keun Sohn, Dae Hee Lee; J Korean Soc Fract 1999;12(2):440-445. Published online April 30, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.2.440

Abstract PDF

Perilunar dislocation is not a common injury. When it occurs it is usually dorsal. Only a few isolated cases have been reported of volar perilunar dislocation, in which the capitate is displaced volar to the palmar flexed lunate. Like its more common dorsal counterpart, volar perilunate dislocation usually requires either a concomitant fracture of the scaphoid or scapholunate dissociation. Many authors have been proposed the mechanism of injury, forced hyperflexion, hyperextension with supination of the forearm and violent trauma with extensor tendon rupture. The diagnosis is most easily made on the lateral view. Closed reduction using finger-trap traction should be the initial step in management. Although successful treatment has been reported with a closed reduction alone, open reduction is probably indicated in most cases to align and stabilize the bones. We are reporting on a patient of volar perilunar dislocation without a fracture of the scaphoid or scapholunate dissociation of the right hand associated with extensor tendon rupture.

Ipsilateral Fractures of Femoral neck and Shaft: Byeong Hwan Kim, Sung Keun Sohn, Soo Jin Park; J Korean Soc Fract 1999;12(1):13-20. Published online January 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.1.13

Abstract PDF: Ipsilateral fractures of the femoral neck and shaft are uncommon injuries with the difficulties in diagnosis and treatment. The femoral neck fracture of this injury is commonly missed on initial evaluation. The overlooked femoral neck fracture may lead to higher risk of complications such as avascular necrosis of the femoral head, nonunion and coxa vara. The authors reviewed nine cases of ipsilateral femoral neck and shaft fracture treated in our clinic from June 1990 to March 1997, and average follow-up period was 39 months(range, 16 to 97 months). The results obtained were as follows ; 1. The cause of injury was traffic accident and one femoral neck fracture was missed initially. 2. The most common site of femoral neck fracture was basicervical in 7 cases and that of shaft fractures was middle 1/3 shaft in 6 cases. 3. Two cases were treated with femoral reconstruction nail, seven with multiple neck pinning and dynamic compression plate for shaft fracture. 4. There were complication such as 2 cases of delayed union of femoral shaft, 1 case of nonunion of femoral shaft. 5. It should be treated with anatomical and rigid internal fixation in femoral neck fracture having first priority.

Treatment of the Humeral Shaft Fracture in Adult: Sung Keun Sohn, Silng Soo Kim, Sung Wan Kim, Jin Gu Kim; J Korean Soc Fract 1997;10(3):628-633. Published online July 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.3.628

Abstract PDF

It has been generally agreed that most fractures of the humeral shaft are treated non-operatively, but recently the rate of operative treatment was increased due to high incidence of segmental fracture and combined injury. Authors analyzed 47 cases of the humeral shaft fracture in adults that treated from May 1990 to May 1994 at the Department of Orthopaedic Surgery, College of Medicine, Dong-A University. The results were as follows : 1) The mean age was 38.5 years and the most common cause of injury was traffic accident in 23 cases(48.9%). 2) The most common type of fracture was spiral or oblique fracture in 17 cases(36.2%). 3) Six cases were treated conservatively, 29 were treated operatively after failure of attempt to treat conservatively, and 12 were treated only operatively. 4) The mean time of the conversion from conservative treatment to operative treatment was 3.7 weeks after treatment, the causes of failure in conservative treatment were assumed incooperative on fracture care and muscular weakness in elderly patient, severe angular deformity and displacement after trauma. 5) In the conservative treatment group, clinical union was accomplished at 8.2weeks and the mean radiological union at 14.6 weeks, while in operative treatment group, the clinical union at 7.6 weeks and the radiological union at 13.5 weeks. 6) In radial verve palsy, complete or incomplete ruptures were found in 4 cases among 6 exploratioins, so we think that early exploration is considerable option.

A clinical study of tibial condylar fracture: Kyu Yeol Lee, Myung Soo Lee, Sung Keun Sohn; J Korean Soc Fract 1996;9(4):958-969. Published online October 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.4.958

Abstract PDF: The tibial condyle fracture was descirbed first by Cooper in 1825, which involves articular surface of the proximal tibial and often pnduces disabilities of the knee joint due to accompanied by injuries to ligaments and menisci, frequently. There are much controversies in the method of the treatment in the fracture of the tibia condyle, but todays, the anatomical reduction and firm internal fixation is recommanded with early knee motion for good results. The authors analyzed 43 cases of tibia condylar fractures that treated at Department of Orthopaedic Surgery, College of Medicine, Dong-A University from March 1990 to May 1995. The results were obtained as follows: 1. The most common age group was 4th decade. 2. The most common cause of injury was motor vehicle accident in 28 cases(65.1%) and others were slip down, fall down and sports injury, etc. 3. According to Schatzkers classification, thr most common type was type II and VI in 10 cases(23.3%) individually. 4. The most common soft tissue injury was ligament injury in 16 cases(37.2%), and the most common associated fracture was fibular fractures(13 cases). 5. By Porters criteria, 16 cases(76.2%) among 21 conservative cases and 16 cases(12.7%) among 22 operative cases had acceptable results. 6. The most common complication was limit of motion of knee joint(8 cases) and then, traumatic arthritis, angular deformity, infection, joint instability were seen. 7. There was no different result between conseHative and operation method in our study, but we think the simple comparision was meaningless because of the degrees of injury to the objects of the two treatment methods were different. 8. The factors to effect the prognosis were as fellows; the depression, displacement of the fracture, soft tissue injury, anatomical reduction and early knee exercise, etc.

Supracondylar Closing Wedge Osteotomy for Posttraumatic Angular Deformity of Distal Humerus: Methods for Reducing Secondary Deformity: Sung Soo Kim, Sung Keun Sohn, Chul Hong Kim; J Korean Soc Fract 1996;9(3):706-714. Published online July 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.3.706

Abstract PDF: The angular deformity of distal humerus is one of the most frequent complication of supracondylar fracture in growing children. The deformity rarely limits function, but corrected by patients request due to cosmetic problem. Many orthopedic surgeons have suggested various operation methods but with high incidence of complications related to these operations, also we often experience secondary deformity after inaccurate osteotomy. Therefore to identify desirable operative method to reduce secondary deformity, a retrospective study of 17 patients operated with angular deformity following distal humerus fracture was carried out in which replanning with isosceles triangle method was done in all cases. The following results were obtained. 1. The complications were two cases of metal failure and one of non union. 2. The basic requirement of closing wedge osteotomy without secondary deformity was that:the center line of isosceles triangle whose apex angle should be identical to the deformity angle and be placed on the concave apex of deformity, should overlap the transverse bisector of hurnerusforearm axes. In inevitable cases, the disparity should be minimized to alleviate secondary deformity. 3. The translation was calculated by the equation of T=Dxsin Î±(T:translation, D:proximal or distal migration of the point of contact of humerus-forearm axes, Î±:angle of the deformity). In conclusion, we think that the deformity may be corrected safely and easily using minute preoperative planning with application of above principle.

Abstract PDF: The patella, the largest human sesamoid bone, is important functional component of the knee extensor mechanism and its treatment is considered to be very important because the fracture involvement to the articular surface occures in most of the cases. We report 40 cases of fractures of patella treated with operative methods from January 1990 to June 1995 at the department of orthopaedic surgery, Dong-A university hospital. The results are as follows. 1. Among 40 cases, 29 cases were male and 24 cases were belong to 3rd decade and 4th decade. 2. The most common cause of injury was slip down or fall down. 3. The pattenrs of fracture were transeverse in 21 cases, vertical in 2 and comminuted in 17. 4. The methods of surgical treatment were modified tension band wiring in 33 cases, circumferential wiring in 2, partial patellectomy in 4 and total patellectomy in 1. 5. In patient treated with modified tension band wiring, range of motion of the knee was 128 and mean duration of bone union was 9.2 weeks. 6. Complications were limitation of range of motion in 3 cases, refracture by slip down in 1 case and wire migration in 1 case.

The Treatnent of Fracture and Nonunion of the Carpal Scaphoid: Sung Keun Sohn, Sung Soo Kim, Myung Soo Lee; J Korean Soc Fract 1996;9(2):264-273. Published online April 30, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.2.264

Abstract PDF: The scaphoid fracture is the most common fracture in carpal bones and its incidence of nonunion, avascular necrosis and ostoarthritis is high because of its precarious blood supply and diffculties of diagnosis and treatment. Authors analyzed 14 cases of carpal scaphoid fractures that treated at the Department of Orthopaedic Surgery College of Medicine, Dong-A University from March 1991 to February 1994 The results were obtained as follows 1. The results of treatment were evaluated by Maudsley method. Excellent or good results were 7 of 8 cases in the Herbert screw fixation, 1 of 2 cases in the K-wire fixation and all cases in the conservative treatment and the bone graft. 2. The mean duration of immobilization was no significant difference regardless of the treatment method in fractures. But in nonunions,there was a decreased immbilization time with the Herbert screw fixation as comparing with the K-wire fixation. 3. In fractures, Herbert screw fixation showed early bone union comparing to other treatments. And there was no significant difference of bone union regardless of the treatment method in nonunion.

Treatment of acromioclavicular dislocation by a Phemister method: Sung Keun Sohn, Kyung Taek Kim, Kyu Yeol Lee, Sung Soo Kim, Hyung Hwan Lee; J Korean Soc Fract 1996;9(1):154-160. Published online January 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.1.154

Abstract PDF: Acromio-clavicular joint dislocation occurs when both acromioclavicular and coracoclavicular ligaments are ruptured and brings to deformity, arthralgia and limitation of motion of the shoulder joint. The treatment of complete acromioclavicular dislocation is controversial, and both of the conservative and surgical treatment are reported to be relatively successful. But, conservative treatment have many disadvantages and now rarely advocated. Recently, there are increasing tendencies to treat the acromioclavicular dislocatioll with anatomical reduction of acromioclavicular joint and rigid internal fixation for early movement of shoulder Joint. We report the results of 16 cases of acute acromioclavicular dislocation treated with Phemister or modified Phemister method. The results are as follows. 1. Among 16 cases,14 cases were males and 9 cases were belong to 3rd decade and 4th decade. 2. The most common cause of injuries was slip down. 3. Postoperative difference in coracoclavicular distance on radiogram was 0.1 mm on average. 4. Clinical results were excellent in 14 cases, good in 1 case and acceptable in 1 case. 5. Complications were redislocation in 1 case and K-wire migration in 1 case, but there was no arhritic changes on the affected A-C joint.

The Use of Gamma Nail in Peritrochanteric Fractures of the Femur: Sung Keun Sohn, Kyung Taek Kim, Kyu Yeol Lee, Hyung Hwan Lee; J Korean Soc Fract 1995;8(4):753-759. Published online October 31, 1995; DOI: https://doi.org/10.12671/jksf.1995.8.4.753

Abstract PDF: In old age, trochanteric fracture occurs easily by trivial external force due to osteoprosis and many kinds of treatment has been performed. The goal of treatment in elderly patients with trochanteric fractures is restoration of function to preoperative ambulatory status at the earliest possible time. For this purpose operative treatment is gernerally recommended. The success of operative treatment depends on the stable reduction and secure fixation. Gamma nail is a new intramedullary device which has been applied in the treatment of trochanteric fractures with the benefits of the closed technique such as low blood loss, low risk of infection and short operative time. The implant can be used by the method of static or dynamic. Intraoperative compression of the fracture segments can be achieved by acting on the sliding lag screw and further compression is given by weight bearing. We studied 22 cases of patient who had the trochanteric fracture and treated operatively with gamma-locking nail at the department of orthopaedic surgery, Dong-A university hospital from January 1993 to December 1994. Among 22 cases, 7 cases were stable fracture and 14 cases were unstable fracture by the Evans classification. Mean operation time was 76 minutes and mean blood loss was 303 mf and intraoperative and postoperative complicatins were encountered in 3 cases, femur shaft fracture in 2 casea and lag screw displacement on the femoral head in 1 case. Based on the above results, we have experienced limited utiliBation of the nail because of the mappropriateness between nail and femur itself and non-skillful application technique. We think that if nail shape and assembly for fixating distal screw are improved, Gamma-interlocking nail is a good interraf fixation device which allows early weight bearing ambulation.

Abstract PDF

The lateral condyle fracture of humerus in children is the second most common fracture among the elbow fractures. In dealing with this fracture, we have frequently encountered the various complications due to physeal plate and intraarticular involvement. Change of the carrying angle is one of the common complications, but many authors reported different results about the change of carrying angle. Also, it is too difficult to measure the carrying angle during the early stage of the treatment because of cast immobilization, motion limitation of elbow, and wide variations of radiologic carrying angle according to elbow position changes. We performed this study to find the more stable and predictable new radiologic measuring method about the carrying angle, and then analysed the factors affecting the changes of canying angle of the 23 patients of the lateral condyle fractures of the humerus in children who were treated and followed up more than twelve months at the Department of Orhopaedic Surgery, Dong-A University Hospital from May 1990 to April 1993. The results were as follows. 1. Carrying angles by Beals method showed variable values according to the elbow positions, but A-angles by the new measuring method were relatively stable regardless of the elbow positons. 2. Increase of clinical carrying angle was 3 cases, decrease was 9 cases, and ranges of clinical carrying angle change were from -7 degress to 14 degrees. Increase of A-angle was 7 cases, decrease was 4 cases, and ranges of A-angle change were from -10 degrees to +10 degrees. 3. The change of canying angle showed no correlation with Jacob stage, follow up duration, metaphyseal height and interval between injury and treatment. But the incidence and the amount of carrying angle change were increased according to the increased age at injury(r=0.62, P<0.01). 4. There were statistical significant correlation(r=-0.65, p<0.01) and regression between the change of canying angle and A-angle : Y=-0.99X+0.56(Y:change of clinical canying angle,X; A-angle change), (r2=0.42, P<0.01).

Clinical study of Supracondylar Fractures of the Humerus in Children: Sung Keun Sohn, Kyu Yeol Lee, Byeong Hwan Kim; J Korean Soc Fract 1995;8(1):106-115. Published online January 31, 1995; DOI: https://doi.org/10.12671/jksf.1995.8.1.106

Abstract PDF: The supracondylar fracture of the humerus is the most common elbow fracture in children. There are much controversies for the treatment and variable and frequent complication such as cubitus varus and joint stiffness, etc. For the period of 3 years and 10 months from Mar. 1990 to Dec. 1993, 62 patients with supracondylar fracture of humerus were admitted and treated at the Department of Orthopaedic surgery, College of Medicine, Dong-A University Among them,34 patients who were followed up more than 6 months were reviewed retrospectively. The results are as follows 1. The average age was 6.4 years and sex ratio of male to female was 3.9:1. 2. The extension type was 79.4%, and flexion type was 20.6%. The ratio of left to right was 1.43:1 3. The most common cause of injury is fall from a height in 18 cases (52.9%). 4. The mean duration of bone union was 42.3 days. 5. According to the Holnlberg classification, 3 cases belong to group I(8.8%), 9 to Group II(26.5%),10 to Group III (29.4%), and 12 to Group IV(35.3%). 6. By Flynns criteria, the satisfactory results was in 31 cases(91.2%), and unsatisfactory in 3 cases (6.3%). In Holmberg classification, the higher severity, the higher joint stiffness made the prognosis worse. 7. In conclusion, we believe that percutaneous pinning was a simple, effective method for treatment of displaced supracondylar fractures of the humerus, and the accurate anatomical reduction was required to prevent cubitus varus deformity, which is one of the most serious complication.

A Clinical study of the Tibial Condylar Fractures: Jung Yoon Lee, Sung Keun Sohn, Kyung Taek Kim, Kyu Yeol Lee, Byeong Hwan Kim; J Korean Soc Fract 1994;7(2):269-278. Published online November 30, 1994; DOI: https://doi.org/10.12671/jksf.1994.7.2.269

Abstract PDF: The tibial condylar fracture which involves articular surface of the proximal tibia is common in traffic accident and often produces some disability of the knee joint because it is frequently accompanied by injuries to ligaments and menisci. There are much controversies in the method of treatment in the fractures of the tibial condyle. Although the anatomical reduction and rigid internal fixation with early knee motion are reconmanded to obtain good results, unsatisfactory results have been reported as 20-40% of cases. The authors analyzed 36 cases of tibial condylar fractures that treated at the Department of Orthropaedic Surgery, College of Medicine, Dong-A University from March 1990 to March 1993. The results were as follows: 1. The sex ratio was 2.3: 1 in male to female and most common age group was 4th decade. 2. The most common cause of injury was traffic accident in 25 cases(69.4%). 3, According to Schatzkers classification, the most common type was type II in 10 cases(27.8%). 4. The most common associated injuries were ligament injury in 10 cases(27.8%) and fibular fracture in 30 cases(27.8%). 5. By Porters criteria, 8 cases(80%) among 10 conservative cases and 18 cases(69.2%) among 26 operative cases had acceptable results. 6. The complications were most common in type II(5 cases) and type IV(5 cases). 7. The factors of poor results were as follows : displaced comminuted fracture, fracture associated with severe soft tissue injury or with ligamentous and meniscal injury.

A Clinical Study of the Tibia Pilon Fractures: Jung Yoon Lee, Sung Keun Sohn, Kyung Taek Kim, Kyu Yeol Lee, Dong Man Park; J Korean Soc Fract 1994;7(2):256-268. Published online November 30, 1994; DOI: https://doi.org/10.12671/jksf.1994.7.2.256

Abstract PDF: A pilon fracture, which is defined as a comminuted intraarticular fracture of distal involve the articular surface and metaphysis with occasional extension in the diaphysis. The management has been notoriously difficult due to the associated injury, intraarticular fracture, severe communition of distal tibia, joint incongruity and soft tissue trauma. Most authors has reported good results after a surgical treatment by a principle of AO group treatment. Rescently, Bone et all reports that ROM and outcomes of the severly comminuted or open fractures of the distal intraarticular tibia were very good in using the external fixator. The result of treatment of 22 cases were analysed at the Department of Orthopedic Surgery, Dong-A University hospital from Mar. 1990 to Feb. 1993. The results were as follows; 1. The incidence of pilon fracture is 8.3% of all ankle fracture treated during same period. 2. The most common cause of injury is fall down(63.3%). 3. The most frequent type is type 3 (54.6%).(by Rudei & Allgower) 4. The most common associated injury is compression fracture of spine and calcaneal fracture(4 cases). 5. There are eight cases open Pilon fracture(36.3%) 6. We had treated severe communited fracture and open fracture by using external fixator, we achived good ROM and outcomes. 7. The more accurate reduction, the better clinical result. 8. Complication of the Pilon fracutre were traumatic arthritis, non-union, malunion, wound int, etc.
