Comparison of olecranon fixation techniques following transolecranon approach in intra-articular fractures of distal humerus in adult patients

Abstract

Background: In this study, we assessed functional outcomes among olecranon fixation techniques used following transolecranon approach in patients with comminuted fracture of distal humerus. Methods: The study included 37 elbows that underwent olecranon osteotomy due to distal humerus fracture. Functional outcomes were assessed among patients who underwent fixation via tension band technique, plate, or screw fixation. Results: The implant irritation was seen in 18% of patients who underwent K-wire plus tension band fixation, in 75% of patients who underwent olecranon plate plus screw fixation, and in 18% of patients who underwent cancellous screw fixation. The rate for implant removal was 2.6 folds lower in K-wire plus tension band fixation when compared to olecranon plate plus screw fixation. Conclusion: We concluded that K-wire plus tension band technique and cancellous screw fixation performed in accordance with technical principles caused less skin problem when compared to other techniques. In olecranon fixation, both methods with enhanced stability by tension band can be preferred.
