We used a dynamic shoulder-testing apparatus and nine fresh-frozen, entire upper extremities from cadavera to evaluate the effects of varying degrees of capsulolabral injury on the kinematics of the glenohumeral joint during abduction in the scapular plane and external rotation. Joint kinematics were recorded with use of a six-degrees-of-freedom magnetic tracking device before and after the creation of each capsulolabral lesion in a progressive manner. Dislocation did not occur after simulation of a large Bankart lesion or even after sectioning of the anterior aspect of the joint capsule. However, division of the entire joint capsule (that is, both the anterior aspect and the posterior aspect) resulted in a significant increase (p < 0.05) in posterior translation during abduction in the scapular plane, and two of the nine shoulders dislocated posteriorly. External rotation of the abducted extremity produced no increase in anterior or posterior translation.
我们使用了一种动态肩部测试装置以及九具来自尸体的新鲜冷冻的完整上肢，以评估不同程度的盂唇损伤对肩胛平面外展和外旋过程中盂肱关节运动学的影响。在逐步制造每个盂唇损伤之前和之后，使用六自由度磁跟踪装置记录关节运动学数据。模拟大型Bankart损伤后甚至在切开关节囊前部后均未发生脱位。然而，切开整个关节囊（即前部和后部）导致肩胛平面外展过程中后向平移显著增加（p < 0.05），并且九个肩部中有两个发生了后脱位。外展肢体的外旋未导致前向或后向平移增加。
