title: Little League survey: the Eugene study.
abstract: In a clinical and radiographic survey of the elbows of 120 pitchers ages 11 and 12, 20% were found to have symptoms, 10% flexion contractures, and 23% roentgenographic changes related to traction stresses on the medial side of the elbow. Five per cent had more serious lateral compression findings related to the radial head or capitellum, but none of these had symptoms. Although this represents a definite incidence of abnormal occurrence, there were no statistically significant correlations or interrelations found relating to pitching experience, valgus elbow deformities, symptoms, flexion contractures, or x-ray findings.
