I am a professional pitcher and i was recently diagnosed after my mri with a tear in my common extensor tendon. where is that and how can i rehab it?

Lateral Elbow: The common extensor tendon is the confluence of tendons from the edc, ecrl and ecrb muscles. It is commonly called tennis elbow. Due to overload (eccentric) to these tendons causing them to tear, scar, shorten and hurt. Treatments are many but i would begin with your atc to begin astym treatment. For a symptomatic small tear in an in season athlete may consider platelet rich plasma injection.

Lateral epicondyle: The common extensor tendon originates off the lateral epicondyle. Is your tear partial or complete? If high grade or complete, you may need surgery. If it is a small tear, it may heal with a period of immobilization followed by rehab. I have used platelet rich plasma in my professional pitchers with this problem to speed healing in slow/refractory cases. No pitching until this heals! good luck.

Elbow: The common extensor tendon attaches to the side of the elbow. This injury is also called tennis elbow. Since you are a professional athlete treatment will differ from standard of care as peak performance is a must. A good team including physical rehabilitation, sports medicine and orthopedic physicians can design a plan of care that optimizes the level of performance you need. Best of luck!
