Abstract

Few studies report on periprosthetic humeral shaft fractures after reverse total shoulder arthroplasty (RTSA). The authors evaluated outcomes of 5 patients with this complication who were initially treated nonoperatively. Of 152 patients who underwent RTSA at the authors’ institution from 2012 to 2017, 4 experienced periprosthetic humeral shaft fractures. One patient was referred to the authors for fracture treatment. All 5 patients were initially treated nonoperatively. The mean duration of follow-up was 11.5 months (range, 1.5-26 months). The authors analyzed time to fracture union, Single Assessment Numeric Evaluation (SANE) score, visual analog scale (VAS) score for pain, and active shoulder range of motion. Fracture union occurred in 4 patients treated nonoperatively at a mean of 4.4 months. Mean SANE score was 55 of 100 (range, 20-85). Mean VAS score was 3.4 of 10 (range, 0-8). Mean forward elevation was 83° (range, 45°-110°); mean abduction was 65° (range, 45°-80°); and mean external rotation with the arm at the side was 15° (range, 0°-30°). Many factors must be considered when customizing treatment for patients with periprosthetic fracture after RTSA. This case series indicates that nonoperative treatment of postoperative periprosthetic humeral shaft fractures can be successful.
