PURPOSE To evaluate and report the clinical results of the treatment of distal humerus intercondylar fractures treated with internal fixation through the modified posterior approach. MATERIALS AND METHODS From January 1999 to October 2003, 20 patient who had intercondyle fracture of the distal humerus treated with internal fixation through the modified posterior approach. We evaluated bone union, complication, postoperative elbow function. RESULTS The average follow up period was 12.8 months. Nearly all most cases united at 14 weeks in an average. There were two neuropraxia and two hardware failure. The range of the elbow joint motion was flexion contracture 8 degree (5~15 degree) to further flextion 120 degree (75~140 degree) in average. The functional result with Riseborough and Radin's functional scale were as follows; 13 good, 4 fair, 3 poor. CONCLUSION Not with severe comminuted like type C3 fracture, but in cases with intercondylar distal humerus fracture the modified posterior approach provided satisfactory exposure for open reduction and rigid internal fixation with satisfactory bone union. There was satisfactory bone union and good clinical result in postoperative elbow function.

PURPOSE The purpose of this study is to compare the functional results of Muller type C intercondylar fractures treated by 2 different surgical approaches : lateral and extensile approach. MATERIALS AND METHODS The study is based on 20 patients 21 knees of Muller type C intercondylar fractures. Two surgical approaches, i.e. 13 cases with lateral and 8 cases with extensile approach were used. The functional evaluation of results was done with criteria by Schatzker and Lambert. Excellent and good was grouped superior while fair and failure was grouped inferior. RESULTS Comparative analysis by surgical approach showed that among total 10 cases of C2 fractures, 6 cases(85.7%) of lateral approach and 2 cases(66.7%) of extensile approach were categorized in inferior group. Among the 8 cases in type C3 fractures, 3 cases treated surgically using the lateral approach showed fair and failure results and 3 cases(60%) of the remaining 5 cases using the extensile approach showed good results. CONCLUSION There was no significant result difference between lateral and extensile approach in type C2 fractures, but in C3 fracture, cases with extensile approach showed better results. Therefore the extensile approach should be recommended in C3 intercondylar fractures with intra-articular comminution.
Between 1990 and 1995, 22 comminuted supracondylar and intercondylar femoral fractures in 22 patients were treated with the AO dynamic condylar screw(DCS). Minimum twelve months of clinical and radiographic follow-up evaluation were available on all patients. All cases achieved clinical and radiographic bony union. Functional results were graded using a Schatzker and Lambert's criteria. Results were seen to be excellent to good to fair in 100% of A2 cases, 86% of C2 cases, 75% of A3 cases and 67% of C3 cases. The more comminuted fractures were found to have worse clinical results and more radiographic malunion. The ability to obtain good fixation in osteoporotic bone is distinct advantage of the DCS. The results of DCS fixation compare favorably with previous studies using other fixation devices in comminuted supracondylar and intercondylar femoral fractures
The postoperative complications in open reduction and internal fination of supracondylar and intercondylar fractures of the femur include leg length discrepanfy, infection, skin necrosis, irritation by implants, valgus or varus deformity, bony destruction associated with vascular disturbance, instability of thr knee joint and translation of the frartured surface. The most vulnerable complication among them may be infection. Then infected nonunion is dangerous to the patients and its treatment is very difficult.
Authors evaluated 25 cases of 25 patients who were treated and followed up evaluation over one year in the department of Orthopaedic Surgery, College of Medicine, Hallym University from January, 1988 to June, 1995. All cases were treated by open reduction & internal fixations. Four cases of them had developed infected nonunion. After we treated these cases wr could reach following results: 1. The cause of infection was primarily staphylococcus aureus in all cases.
2. Among 4 cases of infected nonunion, external fixator was preformed in 3 patients and interlocking IM nailing in remainder.
3. The infection was managed with intravenous antibiotics, frequent irrigation. insertion of antibiotic impregnated beads and daily dressing.
4. Erythrocyte sedimentation rate was normalized at average 8.5 months(range, from 1.5 to 26 months).
5. The union was accomplished at mean 5.4 months in 21 cases without infection and at mean 17.7 months(range, from 10 to 35 months) in 4 cases with infued nonuion after infection developed.
6. The main complications were limitated range of motion of the knee(30 to 100 degree flexion) and shortening of affected extremity.
7. In conclusion, we suggest that early removal of implant in situ, external fination and bone graft after infection controlled is an adequate plan for the treatment of infected nonunion in supracondylar and intracondylar fractures of the femur.
