Scapular Dyskinesis

Stretching: The Truth

I'm planning on a series of articles to update our readers on some of the current concepts in pitcher related injuries and diagnoses that most fans have not heard much about.

We've all had our fill of reading about pitchers with rotator cuff and glenoid labrum tears. There are some interesting trends in sportsmedicine that have lead to changes in exercise programs throughout the majors and minors in an attempt to protect pitchers from a cascade of preventable injuries most fans don't know about.

Diagnoses such as:

โ€ขGIRD: (Glenohumeral Internal Rotation Deficit...not to be confused with the stomach malady also known as GERD which Cubs fans get from watching too many losses). Pitching (both cocking phase and deceleration phase) leading to a tight or thickened posterior shoulder capsular ligament plus a loose anterior capsule and loss of internal rotation of the shoulder. Extra external rotation of the shoulder develops at the expense of internal rotation.

โ€ขScapular Dyskinesia: Shoulder blade weakness with altered kinematics.

โ€ขInternal Impingement: Thought to be related to posterior shoulder contracture from GIRD with subsequent instability of the shoulder as the humeral head (ball of the shoulder joint) which shifts back/posteriorly and upward/superiorly). This is a different entity from subacromial or rotator cuff impingement which is more common and typically occurs from friction outside the shoulder joint.

...and finally connecting the dots, sorting out how the the injured or weakened shoulder (scapula) leads to severe strain on the elbow and tearing of the Ulnar Collateral Ligament (aka the Tommy John injury).

My attention to this topic started last summer, when  I heard a remarkable interview on XM radio with renown Orthopedic Surgeon, Dr. Craig D. Morgan with hosts Jim Memolo and Rob Dibble. The focus of the interview was Stephen Strasburg's shoulder tightness and the subsequent ulnar collateral ligament elbow injury that lead to "Tommy John" reconstruction of that ligament last summer. Dr. Morgan said that he had predicted elbow problems in Strasburg by watching the way he held his shoulder.

More on how the arm bone is connected to the...after the jump.

  • Certainly might be the hottest pitcher right now, but he's behind a few pitchers by most objective full season standards.

  • Well noted. You may also note that Lester's Career Playoff ERA is almost a full point lower, and he has a lower WHIP as well.

    Can't have everything, I guess.

  • i'm happy enough with the Lester signing, but Scherzer has more than earned the extra money so far. If he was in the rotation instead of Lester, this team would feel practically bulletproof to me.

    Blaspheme maybe, but I think Scherzer is the best pitcher in the NL right now.

  • Now who can argue with that? I think we're all indebted to Gabby Johnson for clearly stating what needed to be said. I'm particularly glad that these lovely children were here today to hear that speech. Not only was it authentic frontier gibberish, it expressed a courage little seen in this day and age.
