Simple Shoulder Surgery Technique for Rotator Cuff Repair

• Implant can be attached in two steps firmly connecting the tendon to the humerus over a large area
• Minimal instrumentation required, plus no suture management or knot tying steps
• No reduction or mobilization of tissue needed for partial thickness tears

Improved Tendon to Bone Fixation

• Higher pull-out forces than double row fixation using less implants
• Minimizes punctual pressure aiming to reduce risk of loosening post surgery
• Demonstrates less gap formation than double row fixation to optimize contact pressure

Ensuring blood flow and facilitating healing

• Even pressure load over the tendon ensuring good blood circulation
• Permanent and secure repair with no punctual pressure points
• Instrumentation designed to limit depth of medial anchor to prevent excessive compression of tendon

BIOMECHANICAL EVALUATION

In a direct comparison, the new SINEFIX implant had higher pull-out forces and less gap formation than a double-row repair (DDR). 10 fresh sheep infraspinatus tendons were refixed with SINEFIX and DRR (2x medial and 1x lateral all-suture anchor) respectively.

Methodology: after preloading with 10 N, the tendons were cyclically loaded with 10 to 62 N over 200 cycles at 0.2 Hz. The tendons, which were then still refixed, were loaded until they ruptured. View the poster.
