title: Arthroscopic release for shoulder internal rotation contracture secondary to brachial plexus birth palsy:  clinical and magnetic resonance imaging results on glenohumeral dysplasia.
abstract: Internal rotation contracture of the shoulder in brachial plexus birth palsy frequently leads to shoulder dysplasia. Six children underwent anterior arthroscopic release sparing the subscapularis. Clinical examination and MRI were performed preoperatively and repeated at the 5-year follow-up. MRI was carried out for assessment of glenohumeral dysplasia. Passive external rotation was improved by 63.3° without any limitation of active internal rotation. Active antepulsion/abduction was improved by 90°. Remodeling of the glenoid and improved coverage of the humeral head were observed in all cases. Shoulder arthroscopic release sparing the subscapularis seems to be an efficient procedure to restore external rotation without affecting active internal rotation.
