Long-term outcome of trapeziectomy with ligament reconstruction and tendon interposition (LRTI) versus prosthesis arthroplasty for basal joint osteoarthritis of the thumb.

Several surgical techniques are available to treat thumb basal joint arthritis. In this study, we compare the long-term results of a thumb basal joint prosthesis (de la Caffinière or Roseland type prosthesis) with those of trapeziectomy with ligament reconstruction and tendon interposition (LRTI). We could not find any difference between both techniques with respect to impairment, pain reduction, patient satisfaction and disability.
