Differential onset patterns and causes of carpal tunnel syndrome after distal radius fracture: a retrospective study of 105 wrists

There were three onset patterns of CTS after DRF, and each CTS onset pattern had different etiologic mechanisms and different clinical features of CTS. In the acute onset group, a high-energy fracture pattern was associated with CTS. In the subacute and the delayed onset groups, low-energy injury in elderly women was associated with CTS. Both deformity of the fracture and preexisting median nerve dysfunction were suggested as predisposing factor for CTS.
