Four-corner arthrodesis is a usual procedure for treatment of advanced collapse of the wrist. Initially performed with k-wires, hardware development led to use screws, staples and more recently dorsal plates. Published results using circular plates are sparse, and rate of complication and nonunion seem greater than standard fixation means. The goal of this study was to assess the clinical and radiographic outcomes and complications of four-corner arthrodesis using the Xpodey cup and to compare results to literature. Patients who underwent four-corner arthrodesis performed with Xpodey plate, between March 2010 and November 2015, were asked to return to clinic for clinical and radiographic assessment. Patient demographics, range of motion, grip strength and complications were collected from medical records. They completed two functional scores (Quick-DASH and PWRE). A paired t-test was used to compare quantitative values and a P value<0.05 was considered statistically significant. Thirty patients were analysed with a mean follow-up of 3.11±1.7years. Postoperative mean flexion-extension arc of motion was 50.3° (46.3%), mean radio-ulnar deviation was 34.8° (60.7%) and mean grip strength was 79.7% of the opposite side. Pain intensity and pain frequency were significantly decreased by surgery for rest, daily living activities and work (all P<0.001). Mean Quick-DASH score was 30 100 (0–79.55), mean PWRE score was 31.33/100 for pain component (0–82), and 19.23/100 for function component (0–73). Twenty-five patients (83.3%) were very satisfied (n=16), or satisfied (n=9) and 5 globally satisfied (16.7%). None was not satisfied and all recommended this intervention to a relative if needed. VAS for satisfaction was 9.2 (7–10). Twenty-height patients (93.3%) returned to usual activities and 15 returned to work (88.2%). Time away from daily activities was 70.3±34.2 days (range 30–180 days) and mean time off work was 126±91 days (range 45–365 days). The nonunion rate was 16.7% in this study and decreased to 10% after revision of 2 symptomatic non-fused wrists. Watson's procedure using Xpodey cup is a reliable surgical option, conferring good clinical outcomes and a high fusion rate, around 83% in our experience.
