Justin Duchscherer, pitcher for the Oakland A's, was placed on the disabled list for the 3rd time in his career. The previous 2 were for a R hip torn labrum and some exostosis on the femoral head. This one is for his R elbow. Could there be a connection here?
In my thought process, biomechanical problems that injure the throwing shoulder are the same that injure the elbow. It's just a matter of how the athlete chooses to compensate for their LE issues. The baseball pitcher requires a tremendous amount of extension, I/ER in the hips. They really need to be as strong & flexible as a hurdler in track & field. As the R handed pitcher runs out of R hip extension/external rotation in the acceleration phase, they will often drop the elbow to shorten the lever arm to give it a chance to catch up with the body. Another strategy is to lean the torso away from the ball to steal a little more extension out of the hip by getting it to externally rotate.
The other issue is that Justin is one of those pitchers who throws his 2 seam fast ball almost like a screw ball. This creates a tremendous amount of movement on the ball, but really beats up the radial head/capitulum.
