| Summary: | Background and Objective: This study aimed to evaluate the impact of early functional rehabilitation on clinical outcomes and tuberosity healing in older patients undergoing reverse shoulder arthroplasty for proximal humeral fractures. We hypothesized that early functional rehabilitation would not compromise tuberosity healing and would result in comparable or improved outcomes versus postoperative immobilization. Methods: This retrospective matched-pair analysis included patients aged 70 years or older who underwent reverse shoulder arthroplasty for proximal humeral fractures, with 12 to 24 months of follow-up. Group allocation was time-based: earlier patients received immobilization and later patients underwent early rehabilitation. Matching was based on sex, age, body mass index, fracture classification (Neer), and glenosphere size. Outcomes included patient-reported scores, range of motion, and radiographic assessment of tuberosity healing using standardized imaging. Results: Forty patients (20 per group) with a mean age of 80.7 years and a mean follow-up of 16.1 months were included. The early rehabilitation group demonstrated significantly higher Constant scores (p = 0.044), age- and sex-adjusted Constant scores (p = 0.033), and greater active external rotation (p = 0.002). Anatomical tuberosity healing was seen in 28 of 40 patients (70%). Greater tuberosity healing occurred in 75% and lesser tuberosity healing in 85% of patients with available axial imaging. One deep infection occurred in the early rehabilitation group and was successfully managed. Conclusions: Early functional rehabilitation after reverse shoulder arthroplasty in older adults with proximal humerus fractures improved functional outcomes without compromising tuberosity healing. |
