Too Young Pitching Age Linked To Humeral Retrotorsion

Too Young Pitching Age Linked To Humeral Retrotorsion

According to a recent study, baseball pitchers with an ulnar collateral ligament injury who started pitching younger than 10 years of age demonstrated greater dominant limb humeral retrotorsion and nondominant limb humeral retrotorsion than UCL-injured pitchers who started to pitch at 10 years or later, a new study finds.  

“Increased humeral retrotorsion (HRT) has been found to be a risk factor for ulnar collateral ligament (UCL) tears in baseball players. Recent work has demonstrated the age of 11 years as a potential watershed age for humeral retrotorsion development,” the researchers wrote. 

In the study, “Effect of Younger Starting Pitching Age on Humeral Retrotorsion in Baseball Pitchers With an Ulnar Collateral Ligament Injury,” published recently in The American Journal of Sports Medicine, the researchers hypothesized that “in a group of baseball pitchers with UCL injuries, athletes who started pitching before the age of 10 years will demonstrate significantly more dominant limb humeral retroversion when compared with a group of baseball pitchers who reported starting pitching at 10 years or older.”
