Abstract

Background: The purpose of this study was to examine the radiographic and clinical outcomes of stemless reverse total shoulder arthroplasty (RTSA) after a minimum 2-year follow-up.

Methods: Between July 2018 and March 2023, 50 patients underwent 50 stemless RTSA with the Lima component. Twenty-eight patients with a follow-up of more than 2 years were reviewed. The average age was 71.9 years (range, 61-85 years), and the average follow-up period was 2.2 years (range, 2.0-5.1). Bone marrow density of the proximal humerus was measured before RTSA. We evaluated preoperative and postoperative range of motion, clinical score, radiographic change, and postoperative complications.

Results: Significant increases were observed postoperatively in forward flexion (112.0º-162.5º, P<0.01) and internal rotation (from L3 to T12 level; P<0.05). No changes were observed in external rotation (from 43.0º to 45.2º; P=0.762). The clinical scores improved for Korean Shoulder Scoring system (from 64 to 93, P<0.01) and American Shoulder and Elbow Surgeons score (from 17.5 to 27.3, P<0.01). Although radiolucent lines of less than 2 mm were observed in all cases, no osteolysis and loosening of the stemless humeral component was found. Scapular notching was observed in 18 cases (64.3%).

Conclusions: Stemless RTSA showed good radiographic and clinical results after a minimum 2-year follow-up. Level of evidence: IV.

无柄反向全肩关节置换术的放射学和临床效果:至少两年的随访研究。
背景:本研究的目的是对无柄反向全肩关节置换术(RTSA)进行至少2年随访后的放射学和临床结果进行研究:本研究的目的是对无柄反向全肩关节置换术(RTSA)进行至少2年随访后的放射学和临床结果进行研究:2018年7月至2023年3月期间,50名患者接受了50例使用利马组件的无柄RTSA。对随访超过2年的28名患者进行了复查。平均年龄为71.9岁(范围为61-85岁),平均随访时间为2.2年(范围为2.0-5.1年)。在进行 RTSA 之前,我们测量了肱骨近端的骨髓密度。我们对术前和术后的活动范围、临床评分、放射学变化和术后并发症进行了评估:结果:术后前屈(112.0º-162.5º,PC)明显增加:经过至少两年的随访,无茎RTSA显示出良好的放射学和临床效果。证据等级:IV级。
