Slap lesions in pitchers
In this article Ross Hauser, MD. will discuss research concerning return to play in major league baseball pitchers undergoing surgical and non-surgical repair for SLAP lesions.
Doctors at Houston Methodist Hospital published these findings in the American Journal of Sports Medicine:
The published return-to-play (RTP) rates for athletes who have undergone surgical repair of superior labrum anterior-posterior (SLAP) tears vary widely and are generally accepted to be lower in the group of competitive throwers (baseball pitchers). Therefore the effectiveness of nonsurgical treatment should be explored.

The Houston group looked at 119 patients in a single professional baseball organization with persistent shoulder pain that limited the ability to compete.
- Sixty-eight patients had magnetic resonance imaging-documented SLAP lesions.
- All patients had failed 1 attempt at rehabilitation but had continued with supervised physical therapy.
- Treatment was according to an algorithm focusing on the correction of scapular dyskinesia and posterior capsular contracture with glenohumeral internal rotation deficit (GIRD), followed by pain-free return to throwing.
- Scapular dyskinesis or SICK scapula syndrome is considered an overuse injury (common in throwing athletes) in which there is abnormal movement and resting location of the scapula.
- Posterior capsular contracture with glenohumeral internal rotation deficit (GIRD) also dignify abnormal movement of the shoulder with overuse being a possible cause.
Those who failed 2 cycles of nonsurgical treatment were treated surgically.
Success was defined by 2 different standards:
(1) return-to-play (RTP), success was measured in accordance with previous study findings; and
(2) a more stringent standard of return to the same level/quality of professional competition (level A baseball, Double A baseball, Triple A baseball etc.) with the incorporation of a return to preinjury individual performance statistics (earned run average, walks plus hits per inning pitched), termed “return to prior performance” (RPP).
- Sixty-eight athletes were identified with SLAP lesions.
- Twenty-one pitchers successfully completed the nonsurgical algorithm and attempted a return.
- Their return-to-play rate was 40%,
and their return to prior performance rate was 22%.
- Their return-to-play rate was 40%,
- The return-to-play rate for 27 pitchers who underwent 30 surgical procedures was 48%, and the RPP rate was 7%.
- For 10 position players treated nonsurgically, the return-to-play rate rate was 39%, and the RPP rate was 26%.
- The return-to-play rate for 13 position players who underwent 15 procedures was 85%, with an RPP rate of 54%.
- Nonsurgical treatment correcting scapular dyskinesia and GIRD had a reasonable success rate in professional baseball players with painful shoulders and documented SLAP lesions.
- The rate of return after surgical treatment of SLAP lesions was low for pitchers.
- The return-to-play rate and RPP rates were higher for position players than for pitchers.
- Nonsurgical treatment should be considered for professional baseball players with documented SLAP lesions, as it can lead to acceptable return-to-play rate and return to prior performance rates.1
Non-surgical injection therapy for SLAP lesions
In a study from late 2016, doctors at Wayne State University School of Medicine published these findings:
- Of the twenty-four Major League Baseball players who had SLAP tear surgical repair between 2003 and 2010 who met the study criteria:
- 62.5% were able to return-to-play at the Major League level after SLAP repair surgery.
- Of those able to return-to-play, 86.7% were able to return to prior performance.
However, the overall rate of return to prior performance, including those unable to return-to-play rate, was 54.2%. A little more than half had a successful surgery and return to prior performance. However performance analysis of the return-to-play group revealed a statistically significant decrease in innings pitched for Major League pitchers throwing a mean 101.8 innings before injury and 65.53 innings after injury.2
