Subscapularis Tenotomy - most common technique used in a TSA procedure. - Easy to suture - has poor blood supply - can often heal as scar tissue. Subscapularis Peel-Off - least common technique used in a TSA procedure. - repairs back through transosmosis bone tunnels. - bone to tendon healing can be unpredictable - allows surgeon to medialize the tendon. Lesser tuberosity Osteonomy - Most challenging technique to manage subscapularis. - Remove subscapularis with chunk of bone s...
