Biomechanical paring various surgical techniques for acromioclavicular joint reconstruction have reported that semitendinosus tendon graft for coracoclavicular ligament reconstruction provides a substantial improvement in initial stability and a load-to-failure equivalent to the intact coracoclavicular ligaments. Although it represents a biomechanical pared with coracoacromial ligament transfer, there is still a lack of parative studies confirming the clinical relevance of these biomechanical findings.
Background
肩锁关节重建外科技术的生物力学研究表明,半腱肌肌腱移植重建喙锁韧带提供了一个可靠的初步稳定性,抗疲劳载荷与完整喙锁韧带相当。虽然在生物力学上优于喙肩韧带转移,但临床是还缺乏前瞻性对照研究来证实生物力学结果。
背景
Semitendinosus tendon graft for coracoclavicular ligament reconstruction is associated with superior clinical pared with a modified Weaver-Dunn procedure in plete acromioclavicular joint dislocation.
Hypothesis
对于慢性肩锁关节完全脱位,半腱肌肌腱移植重建喙锁韧带在临床上优于Weaver – Dunn术。

Study Design
Twenty-four patients (mean age, 42 years) with painful, chronic Rockwood type III through V acromioclavicular joint dislocations were subjected to surgical reconstruction. In 12 patients, a modified Weaver-Dunn procedure was performed; in the other 12 patients, autogenous semitendinosus tendon graft was used. Clinical evaluation was performed using the American Shoulder and Elbow Surgeons shoulder score and the Constant score after a mean follow-up time of 37 months. Preoperative and postoperative radiographs pare
