title: Short-term results of the Ascension pyrolytic carbon metacarpophalangeal joint replacement arthroplasty for osteoarthritis.
abstract: BACKGROUND
  Osteoarthritis of the metacarpophalangeal joints is difficult to manage due to the high demands placed on any prosthesis. We report the preliminary results of our experience using the Ascension pyrolytic carbon implant.
  
  
  METHODS
  A pyrocarbon metacarpophalangeal joint replacement was implanted into seven patients (10 metacarpophalangeal joints) with osteoarthritis. Patients were reviewed both clinically and radiologically.
  
  
  RESULTS
  At a mean follow-up of 2.2 years (1-4 years) there were no implant failures nor loosenings. Pain scores improved from 68% to 3% postoperatively, and there was a very high rate of patient satisfaction.
  
  
  CONCLUSIONS
  Pyrocarbon implants are a promising solution to a condition which may be otherwise difficult to treat surgically.
