To determine the location of the subscapularis split during arthroscopic Latarjet created by an inside-out technique passing a switching stick from the posterior portal across the glenohumeral joint.
An inside-out technique was used to arthroscopically create a subscapularis split in 20 fresh-frozen human cadaveric shoulders. The distance between the exit point of the switching stick and the upper border of the subscapularis and the anterior circumflex vessels was measured arthroscopically and after open dissection.
Twelve splits were in the upper third of the subscapularis, 3 were at the junction of the upper third and the middle third, and 5 were in the middle third. None were at the junction between the middle and lower third as desired.
Using the inside-out method during arthroscopic Latarjet may produce a high subscapularis split if it is performed from with a switching stick that is inserted through the posterior approach, and passed across the glenohumeral joint at the level of the inferior glenoid.
This study analyzed the relative risk of high subscapularis split during the arthroscopic Latarjet procedure.
确定经关节镜下由内向外技术使用转换棒从前后入路穿过关节盂肱关节创建 Latarjet 时肩胛下肌劈开的位置。
在 20 个新鲜冷冻的人体尸体肩中，使用经关节镜的由内向外技术创建肩胛下肌劈开。在关节镜下和开放解剖后测量转换棒的出口点与肩胛下肌的上缘和旋肱前血管之间的距离。
12 处劈裂位于肩胛下肌的上三分之一，3 处位于上三分之一和中三分之一的交界处，5 处位于中三分之一。没有一处如预期的那样位于中三分之一和下三分之一的交界处。
如果使用从后方入路插入并穿过盂肱关节在肩胛盂下水平的转换棒进行关节镜下 Latarjet 时，使用由内向外方法可能会导致较高的肩胛下肌劈开。
本研究分析了关节镜下 Latarjet 手术中肩胛下肌高位劈开的相对风险。
