First Extensor Compartment Tendon Rupture in the Setting of a Radial Styloid and Both-Bone Forearm Fracture: A Case Report

Case We report on the rare occurrence of first extensor compartment tendon injury at the myotendinous junction after fractures of the radial styloid and both-bone forearm in a healthy 59-year-old man. Here, a novel technique for repair of this unique injury and an additional proposed mechanism of tendon rupture are discussed. Conclusion We advocate for the suspicion of tendon rupture in the first dorsal compartment with fractures of the radial styloid and both-bone forearm. Tubularization and transfer of the abductor pollicis longus and extensor pollicis brevis tendons to the brachioradialis muscle may be of benefit in these patients.
