Abstract

• PURPOSE: To evaluate the functional results of the elbow and the complications after internal fixation for distal humeral fractures. MATERIALS AND METHODS: We reviewed 38 distal humeral fractures; 12 type A, 7 type B and 19 type C by AO classification. There were six low columnar fractures in type A and nine in type C. Six type C fractures were open. The fracture healing and complications were assessed and the functional result was evaluated by rating system of Jupiter et al. RESULTS: Type A fractures were healed in an average of 10.6 weeks, type B 7.7 weeks and type C 11.5 weeks. Ulnar neuropathy occurred in six cases, loss of fixation in two cases, nonunion in one case, heterotopic ossification in one case and traumatic arthritis in one case. The functional result showed excellent or good in 34 cases (89%) and fair or poor in 4 cases (11%). Open fractures showed significantly worse result than closed fractures. CONCLUSION: To obtain the satisfactory results, stable fixation followed by early motion is required in most distal humeral fractures. Ulnar neuropathy occurs postoperatively in high incidence and the result of open fractures is worse than that of closed fractures.
