We describe a technique that arose from the observation of the clinical outcome of failed arthrodeses of the thumb carpometacarpal joint. In these cases a pseudoarthrosis developed which, surprisingly, rarely lead to a poor clinical outcome. Thus we developed a simple technique which deliberately caused the formation of a narrow pseudoarthrosis in the carpometacarpal joint. We present a retrospective review of 248 consecutive patients treated for Eaton stages II and III osteoarthritis. We observed a statistically significant improvement in mean appositional and oppositional pinch strength, mean DASH score (63.8 pre-operatively to 10.5 at final follow-up), and the mean pain score (8.3 to 0.2). We conclude that trapeziometacarpal limited excision arthroplasty is a simple and reliable alternative to existing surgical techniques for treating Stage II or III thumb carpometacarpal joint arthritis.
