Biceps Tenodesis With Interference Screw Fixation: A Biomechanical Comparison of Screw Length and Diameter

Suprapectoral biceps tenodesis: A biomechanical comparison of a new “soft anchor” tenodesis technique versus interference screw biceps tendon fixation

“…However, the ultimate failure load value determined for IS technique is comparable with those reported by other authors (Table 2) (Ahmed et al, 2013;Arora et al, 2013;Golish et al, 2008;Krushinski et al, 2007;Mazzocca et al, 2005;Ozalay et al, 2005;Patzer et al, 2011;Salata et al, 2014;Slabaugh et al, 2011). Therefore, it is indirectly confirmed that the "soft anchor" technique shows excellent fixation strength.…”

“…All IS techniques failed by tendon tearing at the bone-screw interface, which was not observed in the "soft anchor" but has been frequently reported in the literature (Patzer et al, 2011;Sethi et al, 2013;Slabaugh et al, 2011). The present findings suggest that tendon damage at the bone-screw interface may occur during screw insertion, which is required in the IS technique (Lo and Burkhart, 2004).…”

“…8502, Instron, Norwood, MA). Cyclical loading, ranging from 20 N to 100 N (Kusma et al, 2008;Mazzocca et al, 2005), was applied in load control for 500 cycles at 1 Hz (Slabaugh et al, 2011;Su et al, 2013). The maximum load was selected to simulate the load acting on the proximal LHB when a subject is bearing 1 kg weight in the hand with the elbow flexed at 90° (Nordin and Frankel, 2001).…”

Arthroscopic Suprapectoral and Open Subpectoral Biceps Tenodesis: A Comparison of Restoration of Length-Tension and Mechanical Strength Between Techniques

“…27,32,33,35 Arthroscopic suprapectoral and open subpectoral techniques are 2 common distal techniques for biceps tenodesis. 9 Although numerous cadaveric and biomechanical studies have assessed these methods in isolation, 4,7,17,[36][37][38][39][40][41] few studies are available that directly compare the 2 techniques. 9,39 Additionally, there has been increasing recognition that restoration of the anatomic length-tension relationship of the long head biceps is a critical aspect of the tenodesis procedure.…”

Subpectoral Biceps Tenodesis Using Dynamic Endobutton Fixation in a Humeral Bone Tunnel With Interference Screw Augmentation

“…4 Interference screw diameter of 1-mm smaller than bone tunnel diameter is recommended and provides appropriate fixation strength. 30 Flush insertion of the interference screw helps to minimize development of mechanical irritation of the pectoralis major tendon from the fixation device. 4 The described technique has been used in 15 patients to date with follow-up of up to 12 months.…”
