BACKGROUND Some studies have advocated the use of suture-button fixation during the Latarjet procedure to reduce complications associated with screw fixation. However, the sample size of these studies is relatively small, and their follow-up period is short. PURPOSE To investigate the efficacy of the suture-button Latarjet procedure with at least 3 years of follow-up and remodeling of the coracoid graft. STUDY DESIGN Case series; Level of evidence, 4. METHODS A total of 152 patients who underwent the suture-button Latarjet procedure between February 2013 and February 2016 were selected, and 128 patients who met the inclusion criteria were enrolled in this study. Preoperative and postoperative clinical results were assessed. The position and healing condition of the coracoid graft and arthropathy of the glenoid and humeral head were also assessed using radiography and 3-dimensional computed tomography (CT). RESULTS The mean follow-up time was 40.3 ± 5.8 months. There were 102 patients included in this study. The mean visual analog scale score for pain during motion, the American Shoulder and Elbow Surgeons score, the Rowe score, and the Walch-Duplay score were improved considerably. A total of 100 grafts achieved bone union. The overall absorption rate was 12.6% ± 4.3%. Graft absorption mostly occurred on the edge and outside the "best-fit" circle of the glenoid. A vertical position was achieved in 98 grafts (96% of all cases) immediately postoperatively, with the mean graft midline center at the 4 o'clock position. In the axial view, CT showed that 89 grafts were flush to the glenoid, whereas 2 and 11 grafts were fixed medially and laterally, respectively. In all cases, the bone graft and glenoid tended to extend toward each other to form concentric circles during the remodeling process. During follow-up observations, the height of the 11 grafts that were positioned laterally (ie, above the glenoid level) exhibited a wave-curved change. No arthropathy was observed in any patient. CONCLUSION Patient outcomes were satisfactory after the modified arthroscopic suture-button Latarjet technique. Graft absorption mostly occurred on the edge and outside the "best-fit" circle of the glenoid. The graft exhibited the phenomenon of ectatic growing when it fused with the glenoid and finally remodeled to a new concentric circle with the humeral head analogous to the original glenoid. Grafts positioned laterally did not cause arthropathy of the joints within the period of the study.

改良的关节镜Latarjet手术：3年的随访中，缝合线固定实现了出色的重塑。

背景技术一些研究提倡在Latarjet手术过程中使用缝合纽扣固定术，以减少与螺钉固定相关的并发症。但是，这些研究的样本量相对较小，且随访期较短。目的研究缝合纽扣式Latarjet手术至少3年的随访和对喙突移植的重塑效果。研究设计案例系列；证据级别，第4级。方法选择2013年2月至2016年2月之间接受缝合法Latarjet手术的152例患者，并纳入符合纳入标准的128例患者。评估术前和术后的临床结果。还使用放射线照相和3维计算机断层扫描（CT）评估了喙突移植的位置和愈合状况以及关节盂和肱骨头的关节病。结果平均随访时间为40.3±5.8个月。本研究包括102例患者。运动中疼痛的平均视觉模拟量表评分，美国肩膀和肘部外科医生评分，Rowe评分和Walch-Duplay评分得到了显着改善。总共100个移植物实现了骨结合。总吸收率为12.6％±4.3％。移植物吸收主要发生在关节盂的“最适合”圆的边缘和外侧。术后立即将98例移植物（占所有病例的96％）达到垂直位置，平均移植物中线中心位于4点钟位置。从轴向上看，CT显示，有89个移植物与关节盂齐平，而分别有2个和11个移植物固定在内侧和外侧。在所有情况下，在重建过程中，骨移植物和关节盂均趋向于彼此延伸以形成同心圆。在随访观察期间，侧向放置（即在关节盂水平上方）的11个移植物的高度显示出波状变化。在任何患者中均未观察到关节炎。结论经改良的关节镜缝合按钮Latarjet技术后，患者的结果令人满意。移植物吸收主要发生在关节盂的“最适合”圆的边缘和外侧。移植物与关节盂融合后表现出直肠生长的现象，并最终重塑成一个新的同心圆，其肱骨头与原始关节盂相似。在研究期间，侧向放置移植物不会引起关节关节炎。
