Anterior Dislocation of the Shoulder Due to an Idiopathic Deltoid Contracture-the Report of a Rare Presentation

Abstract

Post injection fibrosis leading to muscle contracture is a known complication. Deltoid fibrosis is known to occur following trauma or an intramuscular injection. Idiopathic Deltoid fibrosis leading to abduction contracture and anterior dislocation of the shoulder is a rare entity. Prompt diagnosis and surgery by distal release of fibrosed Deltoid muscle will lead to good functional recovery.
