We report a rare case of deltoid muscle contracture in an adult. The patient was a 40 year old female who visited our hospital complaining of pain and motion disturbance of both shoulder joints. She had received multiple intramuscular injections for migraine treatment for 5 years. Clinical examination revealed winging of the scapula and fibrous bands were seen in the intermediate part of the deltoid muscles. Strength of the deltoid muscles was normal. Adduction, external rotation and horizontal flexion of the shoulders were restricted, -25 degrees, 35 degrees, 90 degrees, respectively. Fibrous bands showed high echo images within low echo areas on ultrasonography and a low intensity area on MRI. In September 1995, surgery was performed on her right shoulder. The deltoid fascia and subcutaneous tissue were thoroughly and widely released. After resection of fibrous bands at the midpart of the deltoid muscle, range of abduction was improved during surgery. She is now able to touch the opposite shoulder with her right hand. No adductive disturbance was seen. The patient was satisfied with the surgical results and we plan on operating on her left shoulder.
