      Abstract

      Introduction

      The aim of this study was to describe a surgical technique and report on patient-based functional outcomes and complications following open reduction and internal fixation in patients with scapular fractures.

      Methods

      The study comprised 14 patients who were treated with open reduction and internal fixation (ORIF) of a scapular fractures between September 2010 and July 2018. Surgical indications were as follows: medial/lateral displacement greater than 20 mm; shortening greater than 25 mm; angular deformity greater than 40°; intra-articular step-off greater than 4 mm; and double shoulder suspensory injuries (including fracture of the clavicle, coracoid or acromion with displacement greater than 10 mm). All patients underwent X-ray examination (true AP, Y scapular view) and computed tomography (CT) scans. Fractures were classified according to the revised (AO/OTA) classification system. Functional outcomes were measured using Constant-Murley scores.

      Results

      Seven patients had glenoid fossa fractures, six patients had scapular body fractures and one patient had an acromion process fracture. All glenoid fossa and scapular body fractures were exposed via the Judet approach. Eleven of 14 patients were given Constant-Murley scores at the final follow-up examination; three patients were lost to follow-up. The mean follow-up after injury was 44 months (range, 6–92 months). We found infraspinatus muscle hypotrophy in four patients. The mean Constant-Murley score was 93.45 (±8.93) for the injured arm and 98.36 (±2.91) for the uninjured arm. The mean score between the injured and uninjured arm was 4.91(±6.49), which is an excellent functional outcome according to the Constant-Murley score.

      Conclusions

      Open reduction and internal fixation of displaced scapular fractures is a safe and effective treatment option that results in a reliable union rate and good-to-excellent functional outcome.
