Fractures of the inferior angle of the scapula represent a rare entity, with few cases published in the literature to date. Their optimal management is still unclear. A systematic literature search was conducted in PubMed and Google Scholar of reports published between 1977 and 2022. Inclusion criteria were cases presenting inferior scapula angle fractures (ISAF) and reporting management and outcomes. Extracted data included patient demographics (age, sex), mechanism of injury, associated injuries, management, procedures performed, and outcomes. Seventeen studies (22 cases; 19 males and three females) were included. The mean age was 33 years (15 adult and seven pediatric cases). High energy injuries were the most common mechanism of injury (77%). Displacement of the fragment was reported in 64%. The most common initial treatment was conservative (77%); of these cases, more than half failed initial treatment (53%). Of the displaced ISAF cases, 89% failed conservative treatment, contrary to 83% of the nondisplaced cases that were successfully treated conservatively. Surgery yielded 100% success both as initial treatment and after failed conservative management. Displaced fractures should be approached surgically, while conservative management should be reserved for nondisplaced fractures.
