Elbow Common Flexor Tendon Repair Technique

Medial epicondylitis, also known as "golfer's elbow," is a common orthopaedic condition that typically results from overuse of the flexor pronator mass. Repetitive eccentric loading of the muscles responsible for wrist flexion and forearm pronation leads to microtrauma and subsequent degeneration of the flexor pronator tendon. Patients with medial epicondylitis typically present in the fourth to sixth decade of life and have an insidious onset of medial elbow pain. Occasionally, medial epicondylitis may result from an acute traumatic event, such as an acute avulsion of the common flexor tendon. Patients should be examined for concomitant elbow pathologies, including ulnar neuritis and ulnar collateral ligament injury. T2-weighted magnetic resonance imaging can show increased signal intensity in the common flexor tendon or a complete rupture. Nonsurgical management is the mainstay of treatment; however, surgical treatment may be indicated in elite athletes and patients with persistent symptoms after conservative treatment. This technique article with accompanying video describes open debridement and repair of the flexor pronator tendon, with an emphasis on restoration of the anatomic footprint and compression across the repair site to promote biological healing.
