Abstract

 Concomitant severe radiocarpal (RC) arthritis with asymptomatic or minimally symptomatic distal radioulnar joint (DRUJ) arthritis can be debilitating for patients. Surgical management of these combined arthritides can pose a dilemma for surgeons and patients. The purpose of this study was to evaluate patients with concomitant RC and DRUJ arthritides who underwent only total wrist arthrodesis (TWA) to determine the need for subsequent surgical management of preoperative asymptomatic/minimally symptomatic DRUJ arthritis.  All patients who underwent TWA between 2008 and 2018 at a single institution were evaluated. Those patients who underwent TWA for degenerative, inflammatory, or posttraumatic arthritis with concomitant asymptomatic or minimally symptomatic DRUJ arthritis preoperatively were included. A retrospective review was performed for demographic variables, TWA indications, pre- versus post-TWA DRUJ symptoms, and severity of DRUJ arthritis on radiographs. Primary outcome measure was survivorship from subsequent DRUJ surgery for development of symptomatic arthritis after initial TWA.  One hundred and eighty-three patients underwent TWA during the study period, of which 39 wrists met inclusion criteria. Indications for TWA included posttraumatic arthritis (  = 22), avascular necrosis of the lunate (  = 10), and inflammatory arthritis (  = 7). The mean clinical follow-up was 5.7 years (range: 1.5-12.7 years). Four patients (10%) who underwent TWA ultimately required a subsequent procedure to address DRUJ arthritis at a mean time of 20 months (range: 3-60 months) after initial TWA. The initial indication for TWA in these patients included symptomatic posttraumatic arthritis (  = 3) and lunate avascular necrosis (  = 1).  In patients with symptomatic RC and asymptomatic or minimally symptomatic DRUJ arthritides undergoing TWA alone, 10% in this series required subsequent surgical management for progressive DRUJ arthritis.  Surgical management of concomitant symptomatic RC and asymptomatic/minimally symptomatic DRUJ arthritides with TWA alone is a reasonable initial approach. Patients should be counseled preoperatively that subsequent surgical management of progressive DRUJ arthritis may be necessary in ∼10% of patients.
