Second Extensor Compartment Entrapment in an Adult Following Distal Radius Fracture.

Extensor tendon entrapment in the presence of distal radius fracture is a known but relatively uncommon complication. Single tendon or entire compartment entrapment has been described through the literature in youths and adults. However these findings generally are limited to a certain age demographic or are found on advanced imaging but are unable to be confirmed intraoperatively. We describe to our knowledge the first known description of second extensor compartment entrapment in an adult seen on computerized tomography scan and confirmed intraoperatively.
