Abstract

Background: Glenoid bone loss represents a challenge in shoulder arthroplasty and often precludes standard implants. The CAD-CAM total shoulder replacement (TSR) is an option in these cases. This study aimed to assess survivorship and long-term patient outcomes of the CAD-CAM TSR.

Methods: Fifty-eight patients that underwent a CAD-CAM TSR by three surgeons at a single tertiary referral centre between 2009 and 2017 were reviewed. The mean follow-up was 70 months (28-130). Data was collected on survivorship, range of movement, Oxford shoulder score (OSS, 0-48), subjective shoulder value (SSV, 0-100%), pain score (0-10), and overall patient satisfaction.

Results: CAD-CAM TSR was undertaken as a primary procedure in 28% (n = 16) for end-stage arthritis with severe glenoid bone loss, and as a revision procedure in 72% (n = 42). Of the total, 17% (n = 10) required component revision at a mean of 24 months (4x prosthesis loosening, 3x infection, 3x periprosthetic fracture). Forward elevation improved from 45° ± 27° to 59° ± 29° (P = 0.0056), abduction from 43° ± 29° to 55° ± 26° (P = 0.034) and external rotation from 8° ± 11° to 16° ± 14° (P = 0.031). OSS improved from 15 ± 8 to 29 ± 9 (P = 0.0009), SSV from 18 ± 16 to 62 ± 23 (P < 0.0001), and pain score from 8 ± 2 to 2 ± 2 (P < 0.0001). 88% of patients would undergo the procedure again.

Conclusion: CAD-CAM TSR is reserved for complex cases involving severe glenoid bone loss, offering significant improvements in pain and function with overall positive patient satisfaction.

CAD-CAM 全肩关节置换术的存活率分析。

背景：盂骨缺失是肩关节置换术中的一个难题，通常无法使用标准植入物。CAD-CAM 全肩关节置换术（TSR）是这些病例的一种选择。本研究旨在评估 CAD-CAM TSR 的存活率和患者的长期疗效：研究回顾了 2009 年至 2017 年间在一家三级转诊中心由三位外科医生实施 CAD-CAM TSR 的 58 例患者。平均随访时间为 70 个月（28-130 个月）。收集的数据包括存活率、活动范围、牛津肩关节评分（OSS，0-48分）、肩关节主观值（SSV，0-100%）、疼痛评分（0-10分）和患者总体满意度：28%（16 人）的终末期关节炎患者因严重盂骨缺损而接受了 CAD-CAM TSR 作为主要手术，72%（42 人）的患者接受了翻修手术。其中，17%的患者（n = 10）在平均24个月后需要进行假体翻修（4次假体松动、3次感染、3次假体周围骨折）。前伸从 45° ± 27° 提高到 59° ± 29° (P = 0.0056)，外展从 43° ± 29° 提高到 55° ± 26° (P = 0.034)，外旋从 8° ± 11° 提高到 16° ± 14° (P = 0.031)。OSS从15±8°提高到29±9°（P = 0.0009），SSV从18±16°提高到62±23°（P = 0.034）：CAD-CAM TSR 适用于涉及严重盂骨缺失的复杂病例，可显著改善疼痛和功能，患者总体满意度较高。
