Application of distal humeral plate in the treatment of distal humerus fracture

Objective To investigate the surgical technique and effect of distal humeral plate (DHP) in the treatment of distal humerus fracture. Methods From July 2008 to October 2010, 11 cases of patients with distal humerus fracture treated with DHP and complete follow-up were selected. According to AO classification, 1 case was type A, 3 cases were type B, 7 cases were type C. All patients were given open reduction DHP fixation treatment, and no external fixation was attached after surgery. 2 days after surgery, patients began to take functional exercise. Mayo Elbow Performance Score (MEPS) and X ray were used to evaluate the clinical effects. Results All patients were followed up for 12 to 22 months, average of 16 months. Fractures were healed in all cases, the mean healing time was 16 weeks, there was no hardware failure or loss of reduction. 10 cases had elbow pain, but 1 case had slight pain. Forearm rotation function of patients were consistent with the contralateral, the average of flexion and extension of the elbow joint was 79°(10 to 130°), the average of elbow flexion was 108° (60° to 130°) and the average of elbow extension was 25° (0° to 80°). The average of Mayo Elbow Performance Score was 91 points (60 to 100 points). The score was excellent in 9 cases, good in 1 case, the excellent and good rate was 90.9%. Conclusion DHP treatment is satisfied with the stability of fixation for comminuted supracondylar fracture of humerus, comminuted fracture of low articular surface, and distal humeral fractures associated with osteoporosis, which can permit patients to take early function rehabilitation .
