Pronator teres muscle strain is a rare sporting injury reported thus far only in cricket and golf players. The injury appears to occur when the sporting club or racket strikes the ground during a forceful swing and causes the elbow to experience an eccentric force during resisted elbow flexion and pronation. On initial presentation, this injury can be mistaken for injury to the medial ulnar collateral ligament, or exacerbation of medial epicondylitis. On examination, bruising and tenderness distal to the elbow over the course of the pronator teres are often present. Advanced imaging confirms the diagnosis and can help in grading injury severity. In this article, we report the case of a patient who was conservatively treated, and returned to function and sport by 6 weeks after a period of rest and restricted activities. The prognosis is excellent for even high-grade strains. Complete return to sporting function without residual weakness is expected.
