Traumatic rupture of the extensor pollicis longus tendon due to hyperextension of wrist

A case of a traumatic rupture of the EPL tendon due to sudden extreme hyperextension of wrist, where the tendon was crushed between the Lister's tubercle and the base of the third metacarpal was encountered. The patient didn't have history of rheumatoid arthritis or steroid injection or any wrist fracture. During surgery, the EPL tendon was found to be ruptured at the level of the lister's tubercle and direct repair was not possible. Reconstruction of the extensor tendon using the palmaris longus tendon was performed. At the 24-months follow-up, the patient showed satisfactory extension of the thumb at interphalangeal joint and full extension and flexion at the wrist.
