Congenital glenoid dysplasia.

Glenoid dysplasia is an anomaly of the scapula characterized by underdevelopment of the bony glenoid and adjacent part of the scapular neck which may be seen as a primary isolated condition, in patients with multiple anomalies or ill-defined syndromes, in well-described syndromes, in mucopolysaccharidoses and related conditions, and in certain skeletal dysplasias. The general subject of glenoid dysplasia is reviewed with reference to descriptions in the literature and personal observations.
