Total arthroplasty with Ivory prosthesis versus resection-suspension arthroplasty: a retrospective cohort study on 82 carpometacarpal-I osteoarthritis patients over 4 years.

Background: To elucidate the performance of carpometacarpal-I joint prostheses in comparison with the current gold standard treatment, resection-suspension arthroplasty (RA), we conducted a study comparing outcomes of the Ivory prosthesis to those of a cohort of patients receiving RA.

Methods: Initially, we had enrolled 34 prosthesis patients and 48 RA patients, of which 5 and 11 were lost to follow-up. We defined Eaton/Littler stage 3 osteoarthritis, no previous surgery, no concomitant arthrosis, no rheumatic arthritis, no history of trauma and a minimum follow-up period of 2 years as inclusion criteria.

Re-motion total wrist arthroplasty: 39 non-rheumatoid cases with a mean follow-up of 7 years.

We evaluated the outcomes of the Re-motion total wrist arthroplasty in 39 non-rheumatoid patients. The mean follow-up was 7 years (range 3-12). Postoperative wrist flexion-extension and radial-ulnar deviation as well as the scores of the Disability of Arm Shoulder and Hand questionnaire and the visual analogue scale pain scores improved significantly.
