Deltoid Osteomuscular Transfer Suppresses Humeral Head Translation Caused by Massive Irreparable Rotator Cuff Tears: A Cadaveric Biomechanical Study

The authors aimed to evaluate the biomechanical effectiveness of a modified deltoid flap transfer, termed deltoid osteomuscular transfer (DOT), in managing massive irreparable rotator cuff tears (MRCTs) using a cadaveric model. Their findings demonstrated that the anterior harvest DOT significantly reduced humeral head translation compared to MRCT under various conditions and improved functional abduction force, suggesting it may provide effective stabilization for patients with irreparable MRCTs.
