Bilateral dysplasia of the neck of scapula and associated anomalies.

Nine cases of bilateral dysplasia of the neck of scapula, combined with a varying degree of hypoplasia and varus position of the humeral head as well as enlargement of the acromion are described. The relation between the clinical and radiologic findings is analysed. Bilateral dysplasia of the neck of scapula with its associated anomalies seems to be a hereditary entity, producing only slight discomfort to the patient. It might be more common than previously assumed.
