Abstract
INTRODUCTION/HYPOTHESIS: The purpose of this study is to determine the mid/long term shoulder function in patients with complete deltoid paralysis and intact rotator cuff. 27 patients with at least 2-years FU were included. MATERIALS AND METHODS: Outcome measures included pain, range of motion (including the swallowtail test STT), deltoid extension lag test DELT and Bertelli test), subjective fatigability using the injured shoulder and postoperative modified Neer ratings. RESULTS: At an average 68 months FU, mean shoulder abduction was 131°, flexion 153°, external rotation with the arm at the side 58° and 58° with the arm abducted. All patients reported quick fatiguability with repetitive use of the injured arm which did not change over time. Average pain score was 2. Eighteen patients had positive STT and DELT tests and all patients had positive Bertelli test. DISCUSSION: This study demonstrates that patients with deltoid paralysis and intact rotator cuff do maintain most of their shoulder function and this is sustained over time. LEVEL OF EVIDENCE: Level IV; prognostic Study: case series.
