Indications
Total wrist arthroplasty should be considered for the rheumatoid wrist when there is severe wrist destruction and partial fusions are no longer appropriate. Patients who are candidates for a total wrist fusion, but in whom the loss of wrist motion would increase their functional disability, should be offered the option of a total wrist implant. A few degrees of wrist motion greatly increases the reach of fingers in space and may have enormous functional consequences.
Patients with rheumatoid arthritis are suitable candidates for arthroplasty because of their low demands and low levels of activity. It remains very questionable whether patients with osteoarthritic or post-traumatic arthritic wrists are good candidates for an artificial joint as their demands may cause early failure of the prosthesis. Certainly, wrist arthrodesis may be the preferred choice for patients engaged in heavy manual labour. When bilateral wrist disease exists, arthroplasty of the dominant side would seem an appropriate choice and has been favoured by other surgeons.
Arthrodesis of the wrist is an effective surgical procedure, but only provides a compromise for pain relief with some loss of motion and is not without complication. |
