Abstract

Background: Non-unions of clavicle fracture after conservative treatment have been treated surgically, but carry a risk of complications. The aim of this study is to report the outcomes of non-operative treatment for patients with non-union of fractures of the mid-shaft of the clavicle following initial conservative treatment.

Methods: This is a retrospective study done at a single centre. Subjects with non-union after conservative treatment of clavicle mid-shaft fractures between March 2004 and February 2019 were included in this study. The exclusion criteria included follow-up period <1 year after the diagnosis of non-union and concomitant upper extremity injury. Final radiographs were assessed for fracture healing, vertical displacement, and shortening. Visual analog scale (VAS) pain scores, shoulder range of motion (ROM) and self-rated outcomes were obtained.

Results: Fourteen patients (five females) with an average age of 58 (range, 29–76) years and a mean follow-up duration of 4.0 (range, 1.5–10.2) years were included in the study. The average vertical fracture displacement was 188.7 (range, 95.4–301.4) percent and the average shortening was 13.2 (range, 2.7–16.9) percent. The average VAS pain score was 0.21 (range, 0–2) points. There was no significant difference in the ROM between the injured and uninjured shoulder (p = 0.715 for forward flexion, 0.070 for abduction and 0.714 for external rotation) and the Constant shoulder score (p = 0.190). Thirteen of the 14 patients were satisfied with the treatment, and 12 returned to their pre-injury level of sports participation.

Conclusions: Non-operative treatment resulted in a favourable outcome for patients with non-union of clavicle fracture after conservative treatment. Self-rated outcome score was excellent, regardless of the presence of radiographic abnormalities.

Level of Evidence: Level IV (Therapeutic)
