Is the extended release of the inferior glenohumeral ligament necessary for frozen shoulder?
PURPOSE: The aims of our study were to assess effects of the extent of capsular release and to define the benefit of additional release of the inferior glenohumeral ligament (IGHL) from inferior to posterior in frozen shoulder. METHODS: Seventy-four consecutive patients with refractory frozen shoulder underwent arthroscopic capsular release and were divided into 2 groups randomly. The release of anterior capsular structures, including the anterior band of the IGHL, was performed in group 1. In group 2 the release extended inferiorly and posteriorly. Constant functional scores were used to assess the outcome. The range of motion (ROM) in various directions was also recorded preoperatively and postoperatively. RESULTS: Follow-up was obtained in 41 patients in group 1 and 29 patients in group 2, and it averaged 28 months. At the last follow-up, there was a significant improvement in Constant score (P < .01) postoperatively in all patients. There was a significant and rapid reduction in th
