Abstract
Background
The aim of this study was to evaluate, prospectively, outcomes following arthroscopic capsular release on patients with a clinical diagnosis of frozen shoulder, comparing immediate mobilization (IM) vs immediate mobilization plus external rotation splintage at night for 10 nights (IM+EXT).
Methods
Patients with a clinical diagnosis of non-traumatic frozen shoulder seen in a single unit from May 2005 to December 2006 were considered for inclusion. Patients were assessed using the Constant score, Oxford shoulder questionnaire, and a visual analogue scale for pain (VAS pain). Patients were randomized to have immediate mobilization (IM) or immediate mobilization plus external rotation splintage at night for 10 nights (IM+EXT).
Results
Thirty patients were included and both groups showed significant improvement in all scores. Mean length of follow-up was 17 months. There was early (4 weeks post-operatively) significant improvement in shoulder function in both groups. The rehabilitation regime used did not affect the overall outcome.
Conclusions
Arthroscopic capsular release produces early symptom improvement in primary frozen shoulder. The use of an external rotation splint at night does not appear to improve outcome over simple early mobilization.
