Distal radius fracture complicated by carpal tunnel syndrome

Abstract

Carpal tunnel syndrome is a well-described complication following distal radius fractures. Onset of symptoms can vary from hours to years after injury. It is important to identify the risks of median nerve compression such as local anesthetic hematoma-block injection, immobilization in a Cotton-Loder position, or malunion. Delayed carpal tunnel syndrome can be treated similar to chronic carpal tunnel in the general population. Although prophylactic carpal tunnel release at the time of distal radius fixation has not been recommended by the AAOS, it is important to recognize and treat acute carpal tunnel syndrome when symptoms occur. Lack of early recognition can lead to a delay in diagnosis and treatment, which can cause permanent nerve dysfunction.
