APEX Shoulder Mastering Surgical Techniques for Clinical Success-ER Lag: When to think Lower Trap Transfer

Video Transcription

Video Summary

In the video, the speaker discusses external rotation lag signs and when to consider a lower trapezius tendon transfer for rotator cuff tears. The speaker acknowledges their mentors and the research and educational support they receive. An external rotation lag sign is the loss of external rotation, and it indicates a disrupted force couple involving the supraspinatus, infraspinatus, and teres minor muscles. The management of massive rotator cuff tears is controversial, and the speaker emphasizes the importance of determining if the infraspinatus tendon is reparable before deciding on treatment options. They discuss the use of MRI findings to assess reparable tendons and explain the advantages of the lower trapezius tendon transfer in restoring dynamic function to the shoulder. The speaker also compares the outcomes of lower trapezius tendon transfer and latissimus dorsi transfer, concluding that arthroscopic lower trapezius transfer provides improved outcomes.
