Intraarticular Fractures of the Sigmoid Notch of the Distal Radius: Analysis of Progression to Distal Radial Ulnar Joint Arthritis and Impact on Upper Extremity Function in Surgically Treated Fractures

Level 3 Evidence
      Studies have established increased risk of radiocarpal joint post-traumatic arthritis (PTA) in patients with displaced intra-articular fractures of the distal radius, although this has yet to be evaluated in the distal radioulnar joint (DRUJ). We hypothesize that patients with displaced intra-articular fractures of the sigmoid notch would have a higher prevalence of DRUJ PTA and greater upper extremity dysfunction compared to fractures without sigmoid notch involvement.
