There is an incidence of failures of total wrist arthroplasties. We review our experiences in revising total wrist implant arthroplasties to arthrodeses. The most common mode of failure of the arthroplasties in our series was metacarpal loosening with dorsal perforation of the stem.

We used for the revision arthrodesis in all our cases tricortical iliac crest bone grafts and additional spongiosa transplants from this donor site region. In one case we used a vascularized iliac crest bone graft to bridge the bone defect because of a bad host quality of the recipient area. Fixation was achieved with plates and screws.

Our average follow-up period was 28 month. 14 patients with 15 failed wrist implants were treated with this technique. 14 patients undergoing arthrodesis attained a solid painless fusion after a single operation. In one case a non-union with a loosening of the screws due to using a non-rigid plate was seen. In this case a revision was necessary to achieve a bone healing. All patients were pain free and achieved an increased grip strength after bony fusion.

Arthrodesis after failed total wrist arthroplasty is a satisfactory salvage procedure even in cases with a bad quality of the recipient area. We recommend a rigid fixation technique to prevent non-unions.
