PURPOSE To evaluate the efficacy of the in situ late osteosynthesis for slightly displaced fractures of the lateral humeral condyle. MATERIALS AND METHODS From 2000 to 2004, 12 patients (8 boys and 4 girls) were managed with in situ late osteosynthesis for fractures of the lateral humeral condyle. The average age at the time of operation was 6 years 1 month (1 year 7 months~9 years 1 month), and the mean amount of fragment displacement was 3.3 mm (2.0~4.5 mm). The operative procedure included curettage and in situ fixation of the fragment RESULTS: Bony union was achieved in all cases after avg. 48 months (33~73 months) follow-up assessment. According to the score system of Dhillon et al, 7 patients had excellent, 3 had good, 2 had fair results. None of the patients developed avascular necrosis or premature closure of the epiphysis. CONCLUSION We suggest that in situ fixation is an effective method for the late treatment of slightly displaced fracture of the lateral humeral condyle.
PURPOSE To evaluate the clinical results of the surgical treatment for established nonunion of lateral humeral condyle fracture using closing wedge osteotomy and bone graft. MATERIALS AND METHODS Six patients diagnosed as symptomatic established nonunion of lateral humeral condyle fracture and cubitus valgus deformity were reviewed retrospectively. The average age was 23 years old and mean follow up period was 32 months. We investigate the changes of the symptoms and radiographic findings, and determine the results by Oppenheim's criteria. RESULTS According to Oppenheim's criteria, 3 patients showed excellent, 2 good, 1 poor. Carrying angle is improved to 10.2 degrees and range of motion was decreased by mean 9 degrees. All of the patients' muscle weakness and pain were improved, and was achieved solid union at the last follow up. CONCLUSION In the treatment of symptomatic established lateral humeral fracture and cubitus valgus deformity, better functional and cosmetic results are anticipated by a closing wedge osteotomy and bone graft.
