Non-union of Non-operatively Treated Displaced Olecranon Fractures

Abstract

Background

With this case series, we report the management of patients who present with non-union after no treatment or intentional non-operative management of a displaced olecranon fracture. We hypothesized that the majority of these patients would be satisfied with their symptoms and function.

Methods

Ten patients (six women and four men) with a mean age of 59 years (range 21 years to 94 years) presented to one of seven surgeons with non-union of a displaced fracture of the olecranon a mean of 17 months (range 3 months to 7 years) after injury.

Results

The mean flexion-extension arc at presentation was 117° (range 100° to 135°) with a mean flexion of 137° (range 120° to 150°) and a mean extension of 21° (range 10° to 40°). Forearm rotational arc was a mean of 172° (range 150° to 180°) with a mean pronation of 86° (range 75° to 90°) and a mean supination of 86° (range 75° to 90°). Two patients who had difficulty participating in daily activities because of pain or loss of function requested operative treatment. Eight patients declined operative treatment.

Conclusions

Patients who present with a non-union after a displaced olecranon fracture managed non-operatively have reasonable elbow function and uncommonly request operative treatment.
