Fractures of the glenoid neck.

Abstract

Glenoid neck fractures are uncommon and have received little attention in the literature. However, these injuries involve a major articulation and can cause considerable morbidity if significantly displaced. Consequently, a review of current diagnostic and therapeutic principles with respect to these potentially challenging fractures is justified. The vast majority of glenoid neck fractures are undisplaced or insignificantly displaced (Type I fractures) and are managed without surgery. Type II fractures, however, are significantly displaced, making surgical management a consideration. Significant displacement is defined as translational displacement greater than or equal to 1 cm or angulatory displacement greater than or equal to 40° (in either the coronol or transverse plane). The primary surgical approach is posterior; however, a superior extension is often necessary. Fixation devices include K-wires, 3.5 mm reconstruction plates, and 3.5 mm cannulated lag screws. Follow-up care and rehabilitation are absolutely critical to optimizing the final functional result.
