Acromial hyperplasia, the sequel of deltoid contracture: A case report.

The major complications of deltoid contracture frequently encountered are abduction contracture, winging of the scapula, humeral head flattening and shoulder dislocation (Bhattacharyya 1966; Chatterjee and Gupta 1983). To our knowledge acromium hyperplasia has not been a reported complication of deltoid contracture in the English-language literature. We encountered a patient who had bilateral acromium hyperplasia that appeared to be secondary to deltoid muscle contracture due to large volumes of fluid injected intramuscularly as a child.
