BACKGROUND: The aim of this study was to assess national trends in the utilization and complication rates of total wrist arthroplasty (TWA) and total wrist fusion (WF) as identified via review of the American Board of Orthopedic Surgery (ABOS) Part II candidate database. METHODS: The ABOS Part II candidate database is a collection of cases reported by candidates of the ABOS Part II board certification oral exam. The ABOS database was queried for all TWA and WF cases performed from 2005 to 2014. Linear regression analyses were used to assess trends in procedure utilization. Treatment diagnoses, patient characteristics, and reported complications were also compared between the 2 treatment cohorts. RESULTS: No significant increases in the proportion of candidates performing TWA or WF, number of TWA or WF cases, nor the number of TWA or WF cases performed per candidate performing those procedures were noted during the study period. Significantly less TWA cases were performed when compared with WF cases (68 vs 327; P = .006). Patients undergoing TWA were significantly older ( P = .005), more likely female ( P < .001), and more likely to have a diagnosis of osteoarthritis ( P = .003) than patients undergoing WF. There were no significant differences in complication rates, including postoperative infection, nerve palsy, or rate of secondary surgery, between the TWA and WF cohorts. CONCLUSIONS: Utilization of both TWA and WF has remained unchanged among emerging career orthopedic surgeons. Although WF is performed nearly 5 times more frequently than TWA, our short-term findings suggest that TWA compares favorably with WF. DOI: 10.1177/1558944716668846 PMCID: PMC5484443
