We treated two cases of deltoid muscle contracture in adult. The first case was a 21-year-old female who complained of abduction deformity of her left shoulder associated with pain. The deformity was first noticed at about the age of fourteen years. There was no history of injection or trauma to the shoulder. The second case was a 26-year-old female with slight abduction deformity of her left shoulder. The deformity was first noticed at about the age of twelve years. She had a history of injection to the shoulder at the age of four. After injection, she developed a pyogenic myositis. She had a past history of the first operation to the left shoulder at the age seventeen. Operations were performed on both cases consisting of excision of the fibrous band and release of posterior fiber of deltoid muscle. After the operation the deformity and pain of shoulder disappeared. The postoperative course was good.
