PURPOSE The aim of this study was to evaluate the union rate and risk factors for delayed union in the early postoperative period after an arthroscopic Latarjet with double-button fixation. METHOD In a retrospective study, postoperative CT scans at 3 months were analysed following an arthroscopic Latarjet with double-button fixation used to treat anterior shoulder instability. Healing of the bone block, its position in the sagittal and coronal planes, and the contact area graft/scapula were analysed. RESULTS Ninety-eight CT scans (98 patients) were included. The rate of healing at 3 months was 63/98 (64%) and four grafts clearly migrated. The position was perfectly flush to the glenoid rim in 67% and under the equator in 96%. The mean contact graft/scapula area was 135 mm 2 (4-420). In multivariate analysis, the risk of non-union at 3 months was associated with tobacco consumption (p = 0.001, aOR = 12.17 95% CI [2.62-56.49]), absence of preoperative glenoid bone defect (p = 0.003, aOR = 8.06 95% CI [2.06-31.56]), and a contact area graft/scapula less than 120 mm 2 (p = 0.010, aOR = 5.25 95% CI [1.50-18.40]). Among 31 non-united grafts, 93% definitively healed on CT scan at 1 year, leaving an overall rate of 93% of united grafts at last follow-up. CONCLUSIONS The rate of union at 3 months after an arthroscopic Latarjet with double-button fixation was 64%, reaching 93% at 1 year. This procedure should be carefully indicated in case of tobacco use or instability without glenoid bone defect, especially when the shoulder is exposed to high-energy trauma in the early phase after surgery.

关节镜双按钮Latarjet:90天内,三分之二的骨块愈合。

目的本研究的目的是评估关节镜下双按钮固定的Latarjet术后术后早期的联合发生率和延迟联合的危险因素。方法在一项回顾性研究中,对经关节镜Latarjet联合双按钮固定术治疗前肩不稳的3个月后的CT扫描进行了分析。分析了骨块的愈合情况,其在矢状面和冠状面的位置以及移植物/肩s骨的接触面积。结果包括98例CT扫描(98例)。3个月时的愈合率为63/98(64%),并且明显移植了四个移植物。该位置与关节盂边缘齐平,占67%,在赤道下方,占96%。接触移植物/肩s骨的平均面积为135 mm 2(4-420)。在多元分析中,3个月时不愈合的风险与吸烟有关(p = 0.001,aOR = 12.17 95%CI [2.62-56.49]),术前无盂盂骨缺损(p = 0.003,aOR = 8.06 95%CI [ 2.06-31.56]),以及移植物/肩s骨的接触面积小于120 mm 2(p = 0.010,aOR = 5.25 95%CI [1.50-18.40])。在31例非联合移植物中,有93%的患者在1年的CT扫描中得到了完全治愈,而在最后一次随访中,联合移植的总治愈率为93%。结论关节镜下Latarjet双按钮固定术后3个月的愈合率为64%,在1年时达到93%。如果使用烟草或不稳定但没有关节盂骨缺损,尤其是当肩膀在手术后的早期阶段遭受高能量创伤时,应仔细指示该程序。62-56.49]),术前未发生盂盂骨缺损(p = 0.003,aOR = 8.06 95%CI [2.06-31.56])以及移植物/肩s骨接触面积小于120 mm 2(p = 0.010,aOR = 5.25) 95%CI [1.50-18.40])。在31例非联合移植物中,有93%的患者在1年的CT扫描中完全治愈,而在最后一次随访中,联合移植的总比例为93%。结论关节镜下Latarjet双按钮固定术后3个月的愈合率为64%,在1年时达到93%。如果使用烟草或不稳定但没有关节盂骨缺损,尤其是当肩膀在手术后的早期阶段遭受高能量创伤时,应仔细指示该程序。62-56.49]),术前未发生盂盂骨缺损(p = 0.003,aOR = 8.06 95%CI [2.06-31.56])以及移植物/肩s骨接触面积小于120 mm 2(p = 0.010,aOR = 5.25) 95%CI [1.50-18.40])。在31例非联合移植物中,有93%的患者在1年的CT扫描中得到了完全治愈,而在最后一次随访中,联合移植的总治愈率为93%。结论关节镜下Latarjet双按钮固定术后3个月的愈合率为64%,在1年时达到93%。如果使用烟草或不稳定但没有关节盂骨缺损,尤其是当肩膀在手术后的早期阶段遭受高能量创伤时,应仔细指示该程序。25 95%CI [1.50-18.40])。在31例非联合移植物中,有93%的患者在1年的CT扫描中得到了完全治愈,而在最后一次随访中,联合移植的总治愈率为93%。结论关节镜下Latarjet双按钮固定术后3个月的愈合率为64%,在1年时达到93%。如果使用烟草或不稳定但没有关节盂骨缺损,尤其是当肩膀在手术后的早期阶段遭受高能量创伤时,应仔细指示该程序。25 95%CI [1.50-18.40])。在31例非联合移植物中,有93%的患者在1年的CT扫描中得到了完全治愈,而在最后一次随访中,联合移植的总治愈率为93%。结论关节镜下Latarjet双按钮固定术后3个月的愈合率为64%,在1年时达到93%。如果使用烟草或不稳定但没有关节盂骨缺损,尤其是当肩膀在手术后的早期阶段遭受高能量创伤时,应仔细指示该程序。
