PURPOSE To investigate the factors which influence on the fixation failure after the compression hip screw fixation for unstable intertrochanteric fractures. MATERIALS AND METHODS Eighty-two patients of unstable intertrochanteric fracture of A2 and A3 type who had underwent operation with compression hip screw were evaluated at least 1 year follow-up in regard to the age, degree of osteoporosis, fracture type, diastasis of fragment, sliding of lag screw, position of lag screw and status of reduction. RESULTS 73 patients out of 82 patients had the union and 9 patients showed fixation failure. The results of fixation failure were 6 cases of migration of lag screw and 3 cases of cut-out of lag screw. There were statistically significant correlations between fixation failure and A2.3 and A3 type. The fixation failure group showed increased medial migration of medial cortex of proximal and distal fragment, which is significantly correlated with fixation failure. There were little statistical significant correlations between age, degree of osteoporosis, status of reduction, position of lag screw, sliding of lag screw and fixation failure. CONCLUSION Another alternative fixation method and technique have to be considered for unstable A2-3 or A3 type because compression hip screw fixation only is very insufficient with high failure rate.
PURPOSE To compare of results between open interlocking intramedullary nailing combined with cerclage wiring and closed interlocking intramedullary nailing in treatment of femoral shaft comminuted fracture, we reviewed retrospectively 62 femoral shaft fractures. MATERIALS AND METHODS We reviewed retrospectively 62 femoral shaft comminuted fractures, who had been followed up for a minimum one year including Winquist-Hansen classification II, III, IV from January 1996 to December 2002. The group I include the patients who treated with closed interlocking intramedullary nailing. The group II include the patients who treated with open interlocking intramedullary nailing combined with cerclage wiring. RESULTS The average bone union time was 18.6 weeks in group I, 27.6 weeks in group II. The complication included 3 delayed unions, 1 nonunion and shortening of more than two centimeters in 1 patents in group I. In group II, The complication included 2 infections, 7 delayed unions and 3 nonunions. CONCLUSION We can use open interlocking intramedullary nailing with cerclage wiring in some femur shaft comminuted fractures, but there are many problems and complications. So we must consider it carefully before using this method.
PURPOSE The insertion site of K-wire for skeletal traction is proximal part of tibia or distal part of femur. However, people prefer proximal tibia over distal femur due to lower risk of infection rate when change to interlocking IM nailing is needed. We evaluated the infection rate of interlocking IM nailing. MATERIALS AND METHODS Fourty-seven patients were included in this study who underwent interlocking IM nailing due to femur shaft fracture.
Traction was applied at the distal femur in 19 cases and proximal tibia in 10 cases before interlocking IM nailing. No skeletal traction was applied to the remaining 18 cases. Thirty-eight patients were male and 9 were female. The average age at the time of surgery was 36.7 years old (range, 15~17 years). The average traction period was 9.5 days (range, 3~33 days) and the average followed-up period was 17.2 months. RESULTS In the distal femoral traction group, 8 cases of superficial pin tract infection developed, but no case of deep infection such as osteomyelitis occurred. In the proximal tibia traction group, 2 cases of superficial pin tract infection developed, but no case of deep infection occurred. In the group that received no skeletal traction before interlocking IM nailing, no case of infection developed. CONCLUSION In femur shaft fracture, the distal femoral skeletal traction followed by interlocking IM nailing of femur, compared to proximal tibia skeletal traction, did not increase the risk of deep infection such as osteomyelitis.

PURPOSE To evaluate the effectiveness of a blocking screw in intramedullary nailing at the tibia proximal shaft fracture. MATERIALS AND METHODS 63 tibia proximal shaft fractures from January 2000 to December 2002 treated with only intramedullary nailing were referred to as group I, and 8 fractures from January 2003 to December 2003 treated with both intramedullary nailing and the blocking screw were referred to as group II. Retrospective studies were done for group I and II. The incidence of nonunion and the postoperative angular alignments were compared. Malalignment was defined as an angle of 5 degrees anteroposteriorly or mediolaterally. RESULTS There were 7 nonunion (11%) in group I in compare with none in group II. There were 21 angular malalignments (33%) in group I and 1 in group II (12%) and most of them had valgus deformity or anterior anglulation. No complications were directly due to the use of the Blocking screw. CONCLUSION The technique of the blocking screw used to be one of the option for proximal tibial nailing at tibial proximal shaft fracture helps to overcome angular malalignments of bones.
PURPOSE To report the results of unreamed nailing using a nail with the largest possible diameter for the management of the open tibial shaft fractures. MATERIALS AND METHODS Nineteen patients with open tibial shaft fractures underwent unreamed nailing with the largest possible diameter according to the isthmic diameter measured on preoperative radiography. There were 1 Grade I, 6 Grade II, 9 Grade IIIa, 3 Grade IIIb open fractures. There were 4 type A, 12 type B, 3 type C fractures according to the OTA classification. Fractures were classified as The nail was introduced after gentle passage of a 7 to 8 millimeter-hand reamer. RESULTS Union was obtained in all cases. However 9 (47%) fractures required an additional procedures before union. In 6 cases, dynamization was done. Two of them were required exchange nailing for nonunion, 1 of two gained bony union through additional bone graft. Three of the others had gained union through exchange nailing, bone graft, bone transport respectively. There were one rotational malunion, one superfical and one deep infection. Interlocking screw breakage developed only in one patient. CONCLUSION Our data indicate that unreamed nailing in the management of open tibial fractures is safe and reliable method. Using a tight fitting nail with the largest possible diameter is a safe and effective way to avoid the problems of screw breakage.

PURPOSE To investigate the effect of fibular malreduction on ankle joint after tibia interlocking IM nailing of tibial and fibular fractures according to type of fibular fractures at preoperation. MATERIALS AND METHODS Thirty-nine patients who had ipsilateral tibiofibular fracture were analyzed clinically and radiographically. The talocrural angle and the distance from joint line to the tip of fibular were measured on both ankle standing AP view. The difference of angle and distance of both ankle were analyzed by paired t-test and correlation between defference and AOFAS score by Spearman correlation coefficients. RESULTS The difference of The talocrural angle and the distance from joint line to the tip of fibular of both ankle was statistically significant (p<0.05). The correlation between this difference and AOFAS score was statistically insignificant (p>0.05). CONCLUSION In tibia interlocking IM nailing of tibia and fibula fracture, malreduction of fibula could cause the change of ankle joint.

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.

PURPOSE To study the development of inferior shoulder subluxation after surgery for proximal humerus fractures. To analyze the mechanism development of such subluxation and the association between different types of proximal humerus fractures, quality of reduction achieved the method of operation performed. MATERIALS AND METHODS A retrospective analysis of 45 proximal humerus fractures that were treated by surgery between March 1997 and July 2002 was done. All patients had a minimum of 12 months of postoperative follow up. Preoperative radiographs were classified by the Neer's classification. Different operative treatment methods, post reduction alignment and the degree of postoperative subluxation if present, were analysed. In order to evaluate effect of loss of negative intraarticular pressure, we compared this series with 15 cases of recurrent shoulder dislocation treated by open Bankart operation. RESULTS 13 patients out of 45 (29%) developed immediate postoperative inferior shoulder subluxation. 3-part fractures of the proximal humerus showed a higher incidence of the same than the 2-part types. The better reduced fractures had lesser rates of subluxation. Open reduction (39%, 11 patients) results in an increased incidence of inferior subluxation than closed methods of reduction (13%, 2 patients). CONCLUSION Inferior subluxation of the humeral head after surgery for the proximal humerus fracture can occur and persist till postoperative period of 2 months. Deltoid muscle tone affected by shortening of humeral neck plays an important role. Early active exercise for restoration deltoid tone may be effective in prevention of inferior subluxation.

PURPOSE Fixation of fracture using modified tension band is a very useful treatment method, but loss of fixation caused by loosening of K-wires still remain problem. So we have studied the usefulness of modified tension band with looped pin in order to prevent loss of internal fixation. MATERIALS AND METHODS From September 1999 to June 2002, we had treated 40 patients with this technique, including 16 patella, 8 olecranon, 8 distal clavicle fractures in which three were nonunion fractures, 5 ankle fractures and 3 acromioclavicular joint separations. We looped the pin which has been used for ring external fixator, in line with its long axis. RESULTS After mean postoperative follow-up of 20 months, there were no loosening of looped pin in all cases and we obtained satisfactory results of functional evaluation. There were no complications of nonunion or metallic irritation. CONCLUSION We concluded that modified tension band with looped pin could prevent displacement of internal fixation, and reduce the subsequent complications. Especially in elbow and shoulder joint that the displacement of fixation pin occured frequently, It was considered as very useful operative technique.

PURPOSE To evaluate indications and effectiveness of intramedullary K-wire fixation for distal radial fractures. MATERIALS AND METHODS Twenty one fractures of distal radius treated with intramedullary K-wire fixation from April 2001 to September 2002 were evaluated. The mean age was 67.8(range 46~82). Severely comminuted intra-articular fractures and Barton's fractures were excluded. One or two K-wires were added percutaneously. To assess the functional result, we used Green and O'Brien score system. The radiographic assessment included a scoring system based on measurements of radial length, radial inclination, volar tilt and step-off of the radial articular surface. RESULTS Average follow up period was 13.5 months. In functional result, excellent and good result were obtained in 18 cases (86%). In radiologic result, mean loss of radial length, radial inclination and volar tilt were 0.9 mm, 1.4degrees, 0.9degrees, respectively. CONCLUSION The advantages of intramedullary K-wire fixation were relatively simple procedure, low occurrence of soft tissue complications and early wrist motion. Intramedullary K-wire fixation was good to maintaining reduction in osteoporotic bone.
PURPOSE To traditional treatment of pediatric femoral shaft fracture has been a traction and spica cast application. But flexible intramedullary nail fixation has been introduced as an alternative to other treatment modalities. With this in mind, we analyzed the clinical and radiologic results of flexible intramedullary nail fixation of pediatric femoral shaft fractures. MATERIALS AND METHODS We analyzed 12 patients (13 cases) who were treated with flexible intramedullary nail and followed up for at least 6 months at the department of Orthopedic Surgery, Inje University Ilsan Paik Hospital since May, 2002. RESULTS In all 12 patients (13 cases) involving 1 case with reoperation because of reduction failure, average duration of bone union was 12.6 weeks. There were no considerable complications except mild post-op knee pain and limitation of motion. CONCLUSION In spite of relatively short term study, a flexible intramedullary nail fixation seems to be a useful method without serious complications on pediatric femoral shaft fracture. However, in big or older pediatric patients, interlocking intramedullary nail fixation may be a better choice rather than a flexible nail fixation because of it's insufficient stability.
PURPOSE To analyze the pattern of posterior column injury in unstable burst fractures and to predict the possibility of dural injury. MATERIALS AND METHODS Retrospective review was carried out on 22 patients of unstable burst fracture from Nov. 1996 to Sep. 2003. The pattern posterior column injury was analyzed by simple x-ray, CT and MRI findings. In simple x-ray, authors analyzed laminar fracture, posterior facet injury, inter-spinous widening and inter-spinous malalignment, posterior bony injury by CT, posterior inter-spinous ligament injury and dural tear by MRI. The statistical analysis was performed using Mann-Whitney test and Chi-square test. RESULTS There were 13 men and 9 women, and mean age was 41 years-old (18~65). The level of injury showed 15 cases in T12-L2, 6 in L3, 3 L4. In simple x-ray, findings were showed 13 cases (59.1%) in laminar fracture, 7 (31.8%) in posterior facet injury, 16 (72.7%) in inter-spinous widening and 8 (36.4%) in inter-spinous malalignment. In CT, findings were showed 13 (59.1%) in laminar fracture, 10 (45.5%) in posterior facet injury, 9 (40.9%) in transverse process fracture. In MRI, findings were showed 18 (81.8%) in posterior inter-spinous ligament injury and were not showed dural tear. The combined cases of posterior bony and ligamentous injury was 6 (27%) and 5 of 6 showed dural tear and the analysis of dural tear and radiologic findings was showed positive correlation (p=0.004). CONCLUSION Posterior ligament injury was more frequent than bony injury in unstable burst fracture. Among the posterior bony injuries, dural tear was more frequent in facet injury. Authors confirmed all dural tear with operation. In cases of posterior bony injury combined with ligamentous injuries, the possibility of dural tear was significantly higher than that of single structural injury (p=0.004).

PURPOSE To determine optimal levels of posterior fixation in thoraco-lumbar bursting fractures according to the Load-sharing classification. MATERIALS AND METHODS From Aug. 1999 to Aug. 2003, 50 patients who had been operated with the posterior fixation in one-body thoraco-lumbar bursting fracture were selected. They were divided into two groups, group I, 6 points and below in the Load-sharing score and group II, 7 points and above. And also, each groups subdivided into two subgroups, A (short segment fixation including below and above one body) and B (long segment fixation including below and upper two body). So patients subdivided into I-A, I-B, II-A, II-B. Change of the corrected kyphotic angle was measured and compared with each subgroups. RESULTS The loss of the corrected kyphotic angle was measured average 1.7degrees in group I and 4.1degrees in group II, and there was significant difference between two groups (p>0.05). The loss of the corrected kyphotic angle in the subgroups was average 1.8degrees in I-A, 1.6degrees in I-B, 3.5degrees in II-A and 4.9degrees in II-B. And there was significant difference statistically in I-A and II-A (p>0.05). CONCLUSION In the thoraco-lumbar bursting fracture with 6 points and below of the Load-sharing score, the fixation of the short segment is a useful method. But in the fracture with 7 points and above, the fixation of the short segment is not enough, and these findings be required the further evaluation for some cause of the loss of corrected angle and treatment modalities including the fixation of the long segment.
