Management of distal humerus fractures

Abstract

Fractures of the distal humerus are complex injuries that can be effectively treated with open reduction and internal fixation (ORiF). Exposure of a complex intra-articular fracture may best be achieved through a posterior approach with osteotomy of the olecranon process. The ulnar nerve must be identified and protected, the articular surface must be reduced anatomically, and rigid fixation must be applied to both the medial and lateral columns of the distal humerus. Range of motion should be initiated as soon as possible postoperatively. Complications such as ulnar neuropathy, elbow stiffness, heterotopic ossification, and nonunion should be treated aggressively. Total elbow arthroplasty represents an effective option for fractures that cannot be treated with ORIF.
