I have a steady flow of baseball players who come to see me for shoulder and elbow rehab. As a former pitcher whose playing career was altered by an arm injury at age 14, I have a particular interest in throwing injuries. My son is a 6’2″ left-handed pitcher that plays showcase baseball. He will be the subject matter of this post moving forward.
Many of the players I see for shoulder and elbow pain suffer from pathological GIRD (glenohumeral internal rotation deficit). While it is common to see throwers with less internal rotation on their dominant side, it is important to assess total shoulder motion to make sure their mobility is within 5 degrees of their non-dominant side. Asymmetry in total shoulder motion and shoulder flexion increase the odds of elbow injuries. Click here to see the correlation in professional pitchers. Additionally, insufficient external rotation gain on the throwing arm increases injury risk. Click here to read an abstract summarizing data within the same group of professional pitchers.
Given this information and my background, I have preached arm care for years to my son. For some background, my son has pitched since he was 9 years old. Since I have been a coach for his team in one capacity or another since he was 10, I have closely monitored and controlled his pitch counts, innings per outing and total innings per year. He has always been able to throw hard, but he had a big growth spurt in middle school and his velocity grew with that.
He now throws between 75-77 mph as a HS freshman. He is projected to be 6’5″ tall and weighs 170 pounds at this time. His showcase coach pitched in MLB, and we have two other organizational pitching instructors with big league experience who supervise his weekly bullpens. His total innings pitched for 2017 = 43. Research indicates anything over 100 significantly increases injury risk. With all that said, he has developed some medial elbow pain over the past 4 months. He has no history of arm trouble to date. My intention is for this post to serve as useful diagnostic and proactive intervention for those who may see and experience similar cases.
It is no secret that elbow injuries have been on the rise in MLB as well as all levels of baseball. I see far too many adolescent baseball pitchers in my clinic with medial elbow pain. Often it is related to pathological GIRD and proximal imbalances in the shoulder complex.
Researchers have been studying biomechanics for years. It has long been a belief that younger pitchers should focus on fastballs and change-ups, while minimizing curveballs. Currently, the prevailing thought and latest evidence seems to suggest that velocity may be the bigger risk factor or determining factor in leading to UCL injuries.
A paper in the August 2016 edition of the American Journal of Sports Medicine from Rush University Medical Center sought to determine factors associated UCLR among MLB pitchers. The hypothesis was that those pitchers who underwent UCLR would have a higher pre injury pitch velocity.
This retrospective case controlled study looked at data for pitch velocity, type and number for every pitcher and game were gathered from the PitchFx database from April 2, 2007 to April 15, 2015. Data from 2013 – 2015 was excluded to avoid lead in time bias, as pitches in these seasons may contribute to injuries in pitchers who have not yet undergone UCLR. Pitchers were classified as control, pre injury or postoperative.
