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:

GIRD: (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.

Scapular Dyskinesia: Shoulder blade weakness with altered kinematics.

Internal 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.

  • Awesome report, and good to see Beeler on his way back.

    I'm also very happy to hear about the bi-level bump for Daniel Lewis. In the Name of Theo, he was the Last of the Full-Season Cuts, and There Will Be Blood for those who unnecessarily slow his development. Sure, he might end up in independent ball pitching for Lincoln. But if everything breaks right, he may even have a shot at joining up with the Gangs of Chicago. I wouldn't bet My Left Foot on it, though.

  • CHARLIE: The Cubs did the same thing with LHSP Eric Jokisch last month, and it has nothing to do with needing the player's 40-man roster slot. 

    The hope is that another MLB club will claim the player, so that you aren't on the hook for any termination pay (which you would be if you release him) AND you pick up $20,000 from the claiming team, all for a guy you don't want going forward anyway.

  • Moosetacos, I like it. All I can think of is a bearded lumberjack dude operating a Mexican style taco truck with a Canadian accent.

  • How strange is this for May? Is it insignificant, or does it suggest some sort of trade might be in the works?

  • The Cubs have sent LHRP C. J. Riefenhauser outright to Iowa. 

    Cubs MLB 40-man roster now stands at 37 (three slots open).

  • yow...the a.gordon/m.moustakas collision now makes the schwarb collision look minor in scope.

    gordon broke his wrist, expected to miss 4+ weeks...and today moosetacos has been diagnosed with a torn ACL. fun times in KC.

  • dodgers calling up julio urias for tommorow's game. neat.

    fernando-mania might have a new heir...dude is 19 (turns 20 in august) and he's got a legit argument for being MLB-ready.

  • Happ was the #9 pick last year, and he moved from OF to 2B in the same offseason that Castro was traded.

    Gleyber also in the picture at second.

  • O&B: I think D. J. Wilson is a legit MLB prospect.

    He is a hyperactive dynamo on the field, a protypical lead-off hitter who is looking to get on base any way he can, a triple machine (if there is such a thing) when he does make solid contact, a daring baserunner who goes berserk once he is on base, and a CF who plays a "no fear" crash & burn style of defense.

    Guys like that sometimes get injured more-often than the average player, but if he can stay healthy and continue to progress, I believe he will be an MLB CF, or at worst a 4th OF.

  • The hot start was nice, but it won't always come easy. It's nice to see them have to work for it every once in a while.
