Role of the superior labrum after biceps tenodesis in glenohumeral stability
Post-SLAP repair shoulder pain may be a result of the tendon of the long head of the biceps (LHB) causing pain due to its extensive innervation. This cadaver study sought to determine whether SLAP repair surgery combined with biceps tenodesis would lead to increased translations in the glenohumeral joint.
In 27 shoulders, SLAP lesions were created. Subsequently, a biceps tenodesis was performed in all shoulders. Tests were conducted at baseline, after creation of SLAP lesion, after tenodesis and after a SLAP repair. The testing protocol included both anterior as well as posterior translations in a neutral position, and anterior translation at 90 degrees of abduction and maximal external rotation.
Except for anterior translations, which remained increased after repair of anterior type II SLAP lesions, no differences were found in translations between the baseline and the repaired condition. Moreover, no differences were found between a SLAP lesion only and a SLAP lesion combined with biceps tenodesis. Taking this into account, additional biceps tenodesis in SLAP repairs may therefore be a appropriate procedure to decrease pain. > From: Strauss et al., J Shoulder Elbow Surg 23 (2014) 485-491.
