Although interposition soft-tissue (biologic) resurfacing of the glenoid with humeral hemiarthroplasty has been considered an option for end-stage glenohumeral arthritis, the results of this procedure are highly unsatisfactory in patients less than 40 years old. Achilles tendon allograft is popular for glenoid resurfacing because it can be made robust by folding it. But one reason that the procedure might fail in younger patients is that the graft is not initially thick enough for the young active patient. Most authors report folding the graft only once to achieve two-layer thickness. We report the case of a 30-year-old male who had postarthroscopic glenohumeral chondrolysis that was treated with Achilles tendon allograft resurfacing of the glenoid and humeral hemiarthroplasty. An important aspect of our case is that the tendon was folded so that it was 50-100% thicker than most allograft constructs reported previously. We also used additional measures to enhance allograft resiliency and bone incorporation: (1) multiple nonresorbable sutures to attach the adjacent graft layers, (2) additional resorbable suture anchors and nonresorbable sutures in order to more robustly secure the graft to the glenoid, and (3) delaying postoperative motion and strengthening. However, despite these additional measures, our patient did not have an improved outcome.
尽管采用肱骨头半关节置换术联合肩胛盂软组织(生物性)重建术被认为是终末期盂肱关节炎的一种治疗选择,但该手术在40岁以下患者中的效果非常不理想。同种异体跟腱常用于肩胛盂重建,因为它可以通过折叠使其变得更厚。但该手术在年轻患者中可能失败的一个原因是,对于年轻活跃的患者来说,移植的跟腱最初不够厚。大多数作者报告仅将跟腱折叠一次以达到两层厚度。我们报告了一例30岁男性患者,该患者在关节镜检查后发生盂肱关节溶解,接受了同种异体跟腱重建肩胛盂及肱骨头半关节置换术治疗。我们这个病例的一个重要方面是,跟腱被折叠后比之前报道的大多数同种异体移植结构厚50%至100%。我们还采取了其他措施来增强同种异体移植的弹性和骨整合:(1)使用多根不可吸收缝线连接相邻的移植层;(2)额外使用可吸收缝线锚钉和不可吸收缝线,以便更牢固地将移植组织固定在肩胛盂上;(3)延迟术后活动和加强锻炼。然而,尽管采取了这些额外措施,我们的患者预后并未改善。
