Proximal versus distal screw placement for biceps tenodesis: a biomechanical study.
PURPOSE To assess the maximum and end torque of a fourth-generation composite humerus model with no screw inserted or with a screw inserted in the distal (subpectoral) position or proximal (suprapectoral) position. METHODS 24 large-size, fourth-generation composite humeri were randomised to the control (n=8), proximal (n=8), or distal (n=8) group. For the latter 2 groups, an 8-mm-head interfe...
متن کاملBiomechanical analysis of subpectoral biceps tenodesis: effect of screw malpositioning on proximal humeral strength.
BACKGROUND Humeral fracture after subpectoral tenodesis of the long head of biceps tendon (LHB) is a rare but devastating complication. PURPOSE To determine whether malpositioned (laterally eccentric) tenodesis screw placement has an influence on humerus strength reduction compared with central placement. STUDY DESIGN Controlled laboratory study. METHODS Two groups, each consisting of 10 ...

Methods: Twenty fresh-frozen cadaveric shoulders were dissected for analysis. Initial anatomic measurements involving the proximal long head of the biceps tendon (BT) were made, which included: the labral origin to the superior bicipital groove (LO-SBG), the total tendon length (TTL), the musculotendinous junction (MTJ) to the inferior pectoralis major tendon border, the MTJ to the superior pec...
متن کاملBiceps Tenodesis with Interference Screw Fixation: A Biomechanical Comparison of Screw Size and Technique
Introduction Numerous surgical procedures have been developed to address pathology associated with the long head of the biceps tendon. Tenodesis might be preferred over tenotomy for several reasons, including improved cosmetic appearance, maintenance of elbow flexion and supination strength, and maintenance of the biceps muscle length-tension relationship. To our knowledge, there have been no s...
متن کاملBiomechanical evaluation of subpectoral biceps tenodesis: dual suture anchor versus interference screw fixation.
BACKGROUND Subpectoral biceps tenodesis has been reliably used to treat a variety of biceps tendon pathologies. Interference screws have been shown to have superior biomechanical properties compared to suture anchors; although, only single anchor constructs have been evaluated in the subpectoral region. The purpose of this study was to compare interference screw fixation with a suture anchor co...
