Big thanks to Daniel Haber MD for letting me observe his surgery and educating me on the procedure and common surgical techniques used to improve patient outcomes post surgery. The picture is not from the actual surgery, but the same procedure: Arthroscopic Rotator Cuff Repair.
The repair involved sewing together multiple muscles from the rotator cuff and reinserting them into their original insertion (greater tubercle).
Lesson learned: superior translation of the humeral head can cause adaptations of the acromion to change it’s mechanical structure to resemble that of an articulating joint surface. The body is very adaptable to stress that helps the short term prognosis of a patient, but can hinder the person’s long term success.
