Carpometacarpal Hemiarthroplasty

Successfully treated patients with hemiarthroplasty in one limb versus a ligament reconstruction tendon interposition in the contralateral limb have expressed that they would undergo the hemiarthroplasty as their first choice between the 2 procedures. As the current solution of hemiarthroplasty for thumb CMC arthritis demonstrates early patient satisfaction and preserves techniques in the event of implant failure, we would recommend the use of hemiarthroplasty as an alternative to ligament reconstruction tendon interposition in patients with Eaton stage II or Eaton stage III arthritis with good trapezium bone stock.
