title: Clinical outcomes of total wrist arthroplasty.
abstract: OBJECTIVE
  Current indications for total wrist arthroplasty include patients with symptomatic end stage posttraumatic wrist arthritis, rheumatoid arthritis, and Kienböck disease, as an alternative to wrist arthrodesis. Arthroplasty may have advantage over arthrodesis because of the ability to retain motion. The purpose of this study was to evaluate the short-term clinical outcomes and complications of the Maestro Total Wrist System.
  
  
  METHODS
  We report the results of a retrospective review of 23 total wrist prostheses implanted in 22 patients. We administered the visual analog pain scale and Mayo wrist and Disabilities of the Arm, Shoulder, and Hand questionnaires. We reviewed wrist motion, grip strength, radiographs, and complications.
  
  
  RESULTS
  At a mean follow-up of 28 months (range, 4-55 mo), the Disabilities of the Arm, Shoulder, and Hand score and Mayo wrist score were 31 and 54, respectively. Mean pain scores improved from 8.0 to 2.2. The mean wrist flexion-extension arc was 90°. Radiographs revealed no evidence of prosthetic loosening. Grip strength averaged 60% of the strength of the opposite hand. Complications occurred in 7 of 23 patients. One failure occurred as a result of deep infection in a patient with prior intercarpal fusion, and was successfully converted to a wrist fusion.
  
  
  CONCLUSIONS
  Total wrist arthroplasty performed for pancarpal arthritis as an alternative to wrist arthrodesis can yield successful outcomes with low short-term failure rates.
