INTRODUCTION
Reverse total shoulder arthroplasty (RTSA) is increasingly performed, with a corresponding rise in associated complications such as periprosthetic fractures. Although implant failure and loosening are well documented, deformation of a humeral stem without loosening has not been previously reported.
CASE REPORT
A 77-year-old woman, 9 years after an RTSA, presented with left shoulder pain after a fall. Initial radiographs revealed a transverse periprosthetic proximal diaphyseal fracture and a deformed humeral component. She was treated nonoperatively with range-of-motion exercises and pain management. One year later, radiographs confirmed fracture healing, and the patient had no pain and had regained full motion.
CONCLUSION
This is the first reported case of deformation of a humeral stem in a shoulder arthroplasty. Nonoperative management was successful for fracture healing.
引言
反向全肩关节置换术（RTSA）的应用越来越广泛，与之相关的并发症如假体周围骨折也相应增加。虽然植入物失败和松动已有充分记录，但此前尚未报道过肱骨干在未松动情况下发生变形的情况。
病例报告
一名77岁女性，在接受RTSA手术9年后，跌倒后出现左肩疼痛。最初的X线片显示假体周围近端骨干横行骨折以及肱骨头部件变形。她接受了非手术治疗，包括活动度锻炼和疼痛管理。一年后，X线片证实骨折愈合，患者无疼痛且恢复了完全活动度。
结论
这是首次报道的肩关节置换术中肱骨干变形病例。非手术治疗成功实现了骨折愈合。
