Results with the Roseland(®) HAC trapeziometacarpal prosthesis after more than 10 years.

The Roseland(®) hydroxyapatite-coated prosthesis is a total trapeziometacarpal joint prosthesis used for the surgical treatment of thumb basal joint arthritis. The aim of this retrospective study was to evaluate its long-term outcomes. Fifty-one patients (64 thumbs) underwent trapeziometacarpal joint replacement with this prosthesis. The mean follow-up was 12.5 years. Survival rate of the prosthesis was 91%. There was either no pain or only occasional pain in 91% of cases. The mean QuickDASH score was 27.6. Abnormal radiographic findings were present in 70% of cases. Since they were often asymptomatic, no further treatment was carried out. Complications were common (25%) and occurred early on but could often be treated without surgery. The long-term results with the Roseland(®) HAC prosthesis are satisfactory in terms of pain relief and function. However, the high complication rate is a major concern.
