    Abstract

    Background: Inferior angle of scapula (IAS) fractures are rare, with very few cases reported. They typically present with pain, loss of shoulder motion, and scapula winging. Operative and nonoperative treatments have been trialed with varying success. The aim of this study was to gather data relating to IAS fractures to develop evidence-based treatment guidelines as none are currently available. Methods: A search was conducted of the PubMed and Google Scholar databases to identify cases of IAS fractures. Data collected about each case included age and gender of the patient, mechanism of injury, fracture displacement, treatment, and outcome. The authors report 2 additional IAS fracture cases. Results: Ten cases were identified for inclusion in this study, 8 from the literature and 2 described by the authors. Of the 10 cases, 7 described displaced IAS fractures and 3 described undisplaced fractures. All displaced fractures treated nonoperatively resulted in a painful nonunion. All that underwent operative fixation, whether acutely or after failed nonoperative treatment, had resolution of pain and a good functional outcome. All undisplaced fractures were treated nonoperatively; 1 had persisting pain. Surgical exploration identified the fracture fragment attached to serratus anterior in 2 cases and attached to both serratus anterior and latissimus dorsi in 2 cases. Discussion and Conclusions: There are limited data available about IAS factures. From the cases reviewed, treatment recommendations include the following: (1) displaced IAS fractures should undergo operative fixation to prevent the development of a painful nonunion; (2) suture repair provides adequate fixation; and (3) undisplaced fractures have a variable outcome when treated nonoperatively.
