  • Common flexor-pronator muscle origin from the medial epicondyle provides dynamic support to valgus stress especially during throwin.
  • Flexor-pronator contractile forces resist valgus stress during early arm acceleration and help produce wrist flexion during ball release. (Sisto DJ, Am J Sports Med 1987;15:260).

Flexor-Pronator Muscle Strain Clinical Evaluation

  • Medial elbow pain during the late cocking or acceleration phases of throwing
  • tenderness just distal to the common tendon origin from the medial epicondyle.

  • A/P, lateral and oblique elbow films indicated, generally normal.

Flexor-Pronator Muscle Strain Classification / Treatment

  • generally responds well to a period of active rest with antiinflammatory medication, physical therapy, and gradual return to throwing.
  • Consider  corticosteroid injection for chronic flexor-pronator tendinitis, avoid injection in the region of the ulnar collateral ligament.
