Internal Impingement

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.

  • Phil,

    With Mutton on the DL now, does Victorino finally get to Iowa?

  • Chat ... is happening.

  • They call me Schwarberino because I'm basically Ruth,
    and as long as we're rapping I'm gonna tell you the truth:
    This team would be even better if I wasn't laid up;
    we'd win the World Series, the Superbowl, and the Stanley Cup.
    As long as we're at it, I'm putting the Premier League on notice.
    Hell, if I were healthy, the Cubs could run for POTUS.
    My busted knee's even sadder than this presidential kerfuffle,
    but my first rehab assignment will be the World Series Shuffle.

    I am avoiding grading papers.

  • I definitely hang around here looking to reply to your comments as noticed by my nearly year long absence.

    there's a fine line between posting something relevant, useful or at least humorous versus posting something irrelevant, useless or unfunny...actually it's rather quite a thick line and easy to see for most people not named crunch.

  • I agree completely with Dusty. I appreciate him much more as the Nats skipper than as the Cubs.

  • so, what you're saying is you keep bringing up something over and over and over and over and over and over and over and over and over and over and over and over and over like you did with this issue for years back in the day...and obviously still into today...

    ...but that's fine if you do it.

    brb, forming my next dozen replies for why you should shut up and never say anything about it again...oh wait, no i'm not because i'm not hanging around looking to tell you to shut up about repeating the same thing over and over and over and over...

  • Heyward looked fine shagging flies in BP. Wouldn't surprise me to see him in the line up tomorrow.

  • this seems like it could be an interesting series...parachat worthy.

  • speed leads...nothing ever changes. that's been a dusty thing since...forever.

    holy shit, really? I made the comment because I had just discovered this novel trait that Dusty possesses.

    btw, check out the leadoff hitter of the WS champion KC last year.

    waaaat????? again with the knowledge dropping, I literally had no idea.

  • speed leads...nothing ever changes. that's been a dusty thing since...forever.

    worst part is he's barely a speedster...just the best fitting.

    btw, check out the leadoff hitter of the WS champion KC last year.

  • Gotta make sure you're not clogging up those bases.

  • Guess the OBP of Dusty's lead off hitter tonight?

    .221/.272 for his career

  • CRAIG: Albertos was throwing both his fastball and curve for strikes today, displaying the best command I've seen from him so far. The Cubs have limited his outings at EXST, so he hasn't been stretched-out beyond one inning on a semi-regular basis.  

  • K-K-K inning for Albertos, 9/13 strikes. How did he look? All fastballs, or did he get some breaking pitches for the K's?

    Is Moreno showing any hint of improved velocity?

  • Awesome! Also, dammit! I just finished a Russell verse!

    I’m Addison Russell, flashin’ leather and muscle
    Hit a grounder up the middle, damn right ya better hustle
    I don’t miss, you know this, my D is the dopest,
    I’m lovin’ it and glovin’ it and shovelin’ it to Zobrist
    Another twin killing, score it six-four-three
    If I keep this up they’ll name another street for me
    There ain’t no SS better than Russell
    And I’m just here to do the World Series Shuffle
