Fate of failed Meuli total wrist arthroplasty.
Sixteen Meuli wrist arthroplasties in 13 patients suffering mainly from rheumatoid arthritis were revised for failure. Causes for failure were mechanical problems with the implant in three wrists, soft tissue problems in two wrists and a combination of mechanical failure and soft tissue problems in 11 wrists. Management included 11 revision arthroplasties in ten wrists, four arthrodeses and two primary soft tissue reconstructions. Twenty-six additional soft tissue procedures were required in association with the revision arthroplasties or arthrodeses. Five of the 11 revision arthroplasties had to be converted to arthrodeses after an average of 5 (range 3-8) years. After removal of a failed wrist implant union of the salvage arthrodesis was difficult to achieve in two of the nine instances. This series demonstrates that revision arthroplasty may be a useful alternative to arthrodesis for the salvage of primary wrist arthroplasties in rheumatoid patients. However, complications and reoperations may occur after both revision arthroplasty and arthrodesis.
