Cropped shot of woman in sweater holding her wrist pain
A patient presents 2 years after an ulnar nerve laceration at the wrist that was never repaired. Which of the following treatments can improve the patient’s hand function?
Tendon transfer to improve thumb abduction
Opponensplasty procedures are tendon transfer procedures that can be performed to improve thumb abduction in median nerve palsies
Tendon transfer to correct pseudoclawing
Tendon transfers, such as the Zancolli lasso procedure, can be performed to correct late clawing from an ulnar nerve palsy
Wrist fusion
An ulnar nerve laceration at the wrist would result in loss of intrinsic hand function and clawing. Wrist flexion and extension would not be affected, and wrist fusion is not indicated
Tendon transfer to the extensor pollicis longusy
An extensor indicis proprius tendon transfer to the extensor pollicis longus is performed for an attritional rupture of the extensor pollicis longus, as can occur in the setting of a distal radius fracture
