Introduction: Tension band wiring (TBW) and compression screw fixation are the most common methods used for proximal interphalangeal (PIP) and metacarpophalangeal (MCP) joint arthrodesis. The aim of this study was to compare outcomes between patients treated with those methods. Materials and Methods: A 10-year retrospective comparative study. The study population included skeletally mature patients treated for osteoarthritis or arthritis. Union rates, healing times, complications, and reoperation rates were compared between TBW and compression screw fixation methods. Outcomes were also studied in terms of rheumatic and nonrheumatic patients. Results: The study sample consisted of 56 cases and 44 patients (average age, 53 years). Group 1: 35 patients treated with TBW. Group 2: 21 patients treated with compression screw fixation. There were 32 rheumatic cases and 24 nonrheumatic cases. The average follow-up was 24 months. Union rates were 94.2% (Group 1) and 85.7% (Group 2). Complication rates were 11.4% (Group 1) and 23.8% (Group 2). Reoperation rates were 17.1% (Group 1) and 0% (Group 2). Conclusions: Both methods have high union rates; however, the nonunion incidence in the compression screw group was almost three times higher than in the TBW group. The reoperation rate was higher in the TBW group, mostly due to hardware removal. Healing time was shorter in non-rheumatic patients regardless of the method.
