Wrist arthrodesis for failed wrist implant arthroplasty.
Thirteen wrist arthrodeses were performed for failed wrist implant arthroplasties between 1984 and 1992. Twelve patients were available for review, with an average follow-up period of 28 months. The original arthroplasties consisted of 8 silicone implants and 4 metal-plastic total wrist implants. The surgical method involved a tricortical iliac bone graft and an intramedullary Steinmann pin. There were 7 excellent results, 4 good results, and 1 poor result. All but 1 patient had markedly improved function with no or mild pain. Seven patients had solid fusions and 5 patients had pseudarthroses. Four pseudarthroses occurred at the graft-metacarpal junction and 1 occurred at the graft-radius junction. Each patient with a solid fusion had an excellent result. All graft-metacarpal pseudarthroses were painless and did not limit the patients' activities. There were 17 complications in 9 patients. Wrist arthrodesis can be a successful salvage procedure for failed wrist implant arthroplasty in patients with rheumatoid arthritis. However, the complication rate can be high. Owing to the high incidence of distal graft-metacarpal pseudarthrosis, we recommend using more rigid fixation techniques in patients with failed wrist arthroplasties.
