肩袖部分撕裂的关节镜治疗

目的评估应用肩关节镜下冈上肌肌腱肱骨大结节止点重建术治疗EllmanⅢ级肩袖部分撕裂的临床疗效。方法本组15例(15侧),术前MRI提示肩袖损伤,术中关节镜均证实肩袖部分撕裂超过6 mm,其中关节侧9例(右肩6例,左肩3例),滑囊侧6例(右肩4例,左肩2例),全部滑囊侧及6例关节侧肩袖撕裂合并肩峰撞击征。全部病例均行关节镜下肩袖清创、带线锚钉冈上肌肌腱肱骨大结节止点重建,撞击征阳性病例同时行肩峰成形术。结果平均随访30个月(20～44个月),应用JOA评分标准进行肩关节功能评价,术前平均61.3分,术后94.5分(P0.01)。JOA评价体系中疼痛、功能、活动范围及肩关节提升部分明显优于术前,而外展力量、外旋及内旋部分评分则改善不明显。随访期末按JOA评价标准:优12例,良2例,可1例,术前存在肩峰撞击征的12例,末次随访评价撞击试验阴性。结论关节镜下冈上肌肌腱肱骨大结节止点重建术是治疗EllmanⅢ级肩袖部分撕裂的有效方法。     

Biomechanical Fixation in Arthroscopic Rotator Cuff Repair

Rotator cuff repair remains a challenging and rapidly evolving field. Several recent studies have shown that arthroscopic repair yields functional results similar to those of mini-open and open procedures, with all of the benefits of minimally invasive surgery. However, the “best” repair construct remains relatively unknown, with wide variations in surgeon preference and conflicting evidence in the literature. The most recent developments in basic science, suture and suture anchor technology, and innovative prospects for arthroscopic rotator cuff repair are reviewed.     

肩关节镜下缝线桥技术治疗巨大肩袖撕裂的前瞻性研究

目的 探讨肩关节镜下缝线桥技术治疗巨大肩袖损伤的临床效果。方法 选取我科2018年1月至2020年9月收治的肩袖巨大撕裂病人120例,随机纳入单排缝合组、双排缝合组和缝线桥组,每组40例。比较三组病人治疗前后肩关节疼痛视觉模拟量表（visual analogue scale,VAS）评分、肩关节Constant-Murley功能评分、加州大学洛杉矶分校（University of California at Los Angeles,UCLA）肩关节评分和美国肩肘外科协会（American Shoulder and Elbow Surgeons,ASES）评分及术后并发症发生情况。结果三组病人术后3个月时VAS评分未见明显统计学差异,但是缝线桥组术后6个月及9个月时VAS评分较单排缝合及双排缝合组明显降低,差异具有统计学意义（P<0.05）;术后3、6、12、24个月,缝线桥组的Constant-Murley功能评分、UCLA评分和ASES评分均较单排缝合组及双排缝合组明显增高,差异具有统计学意义（P<0.05）;缝线桥组病人再撕裂发生率较单排缝合组及双排缝合组明显降低,差异...

Early Postoperative Outcomes Between Arthroscopic and Mini-open Repair for Rotator Cuff Tears

The purpose of this study was to compare early postoperative outcomes between arthroscopic and mini-open repair for rotator cuff tears smaller than 3 cm to determine whether arthroscopic repair causes less postoperative pain and allows for faster recovery of range of motion. Sixty patients scheduled for rotator cuff repair were randomized to either an arthroscopic repair group (30 patients) or a mini-open repair group (30 patients). Pain level, range of motion, shoulder stiffness, and complications were compared between the 2 groups from immediately postoperatively to 6 months postoperatively.Although no statistically significant difference was found in mean visual analog scale pain scores between the 2 groups during the 6 months postoperatively, mean visual analog scale pain score was significantly lower in the arthroscopic repair group compared with the mini-open repair group at postoperative days 1 and 2 (P=.02 and P=.04, respectively). No significant difference existed in postoperative range of motion, duration of rehabilitation, shoulder stiffness, or complications between the 2 groups; however, the use of additional analgesics in the arthroscopic repair group was significantly lower than in the mini-open repair group (P=.03).Arthroscopic and mini-open repair had equivalent clinical outcomes in the early postoperative period. The hypothesis that arthroscopic repair would cause less postoperative pain and allow faster recovery of range of motion in the early postoperative period compared with mini-open repair was not supported.     

Anatomic Reduction and Next-Generation Fixation Constructs for Arthroscopic Repair of Crescent,L-Shaped,and U-Shaped Rotator Cuff Tears

Emerging techniques and instrumentation have allowed orthopaedic surgeons to achieve rotator cuff repair through an all-arthroscopic technique. The most critical steps in rotator cuff repair consist of proper identification of the cuff tear pattern and anatomic restoration of the torn tendon footprint. With anatomic reduction of the rotator cuff tendons, a sound fixation construct can help restore rotator cuff contact pressure and kinematics, allowing for decreased repair tension and optimal healing potential. We provide surgical methods to recognize tear patterns and present a repair construct that will restore the anatomic footprint of the torn rotator cuff tendon. The key, initial maneuver to restore the anatomic footprint of the cuff includes placement of a suture anchor at the anterolateral corner for L-shaped tears and at the posterolateral corner for reverse L–shaped and U-shaped tears. After insertion of the medial-row anchors, the tendon stitches should be planned by use of a grasper to hold the tendon in a reduced position and guide location of the stitch. The lateral row with suture bridge can be visualized, and the final repair construct should produce an anatomic restoration of the rotator cuff footprint.
