Ulnar nerve entrapment syndrome in baseball players

Abstract

Ulnar nerve entrapment at the elbow has been described in the literature. This paper deals with 19 skeletally mature baseball players with ulnar nerve entrapment who underwent surgery for correction of the problem. The surgery consisted of anterior transfer of the nerve and placement deep to the flexor muscles. Six players quit baseball because of continuing elbow problems, nine returned to playing, and four were lost to follow-up. Ulnar nerve entrapment is thought to represent one syndrome in a spectrum of diseases involving the medial side of the elbow in baseball players. The lesion is amenable to surgery.
