Outcome after surgical treatment of complex elbow fractures: a single-center follow-up study.

Abstract

Elbow injuries present particular challenges for the treating surgeons. The aim of the present study was to evaluate the postoperative outcome after surgical treatment of complex elbow fractures. Retrospective analysis with subsequent clinical follow-up examination of all patients with complex elbow fractures admitted to our level I trauma center over a 6-year period. The patients were stratified into three groups: single fractures of the proximal forearm (olecranon fractures type Mayo IIB, radial head fractures type Mason II-IV), distal humerus fractures (AO type C1-3), and combined injures. The clinical examination included the range of motion, grip strength measured with a Jamar dynamometer, DASH and MEP score. Overall, 39 patients with complex elbow fractures were included in the study. Twelve patients presented with a distal, intra-articular humerus fracture, 16 patients had an isolated proximal forearm fracture and 11 patients suffered multiple fractures. The functional scores showed good overall results, with a median DASH score of 6.7 points and median MEP score of 85.0 points. The median extension deficit in the elbow joint was 15.0° (mean 16.2° ± 12.8°), the median flexion deficit was 5.0° (9.8° ± 12.3°) and the median pronation/supination (overall rotation) deficit was 5.0° (16.7° ± 23.6°). Patients with intra-articular distal humerus fractures showed a significantly increased extension and flexion deficit compared to the other groups. The surgical treatment of complex elbow fractures was associated with good to excellent clinical results. However, distal intra-articular humerus fractures presented the most prominent loss of elbow motion in the follow-up examination.
