Surgical treatment of comminuted intra-articular fractures of the distal humerus with double tension band osteosynthesis.

Abstract

Intra-articular fractures of the distal humerus are usually treated with cancellous screws for the condylar metaphysis itself and two Y-shaped plates for fixation of the metaphysis to the shaft. Twenty-four patients with comminuted intra-articular fractures (class C on AO/ASIF classification) were treated with crossed K-wires for the condylar metaphysis and double tension band osteosynthesis for fixation of the metaphysis block to the shaft. Excellent or good results were achieved in 83% of patients. This technique is easier to perform and more cost effective than most other fixation methods. Additionally, it offers good stability and allows for earlier functioning of the elbow. Complication rates are comparable to other methods of internal fixation.
