A minimal wrist arthroplasty for early wrist osteoarthritis.

Background The most common forms of salvage surgery for wrist arthritis of any stage are four corner fusion and proximal row carpectomy. Younger, high demand patients with early arthritis may not be candidates for this type of salvage surgery. We describe a technique and preliminary case series of a minimal radiocarpal arthroplasty aimed at patients with initial and isolated wrist arthritis (stage 1). This procedure does not preclude any procedure that may become necessary in the future. Patients A series of nineteen male heavy laborers with scapholunate advanced collapse (SLAC grade 1-2) wrist osteoarthritis that felt the wrist arthritis was prohibiting their function enough to warrant surgery, but were unwilling to undergo a salvage procedure, were treated with the technique. The average age was 57.2 (± 7.7) years. The average follow up period was 40.3 months (9-63 months). All patients returned to heavy labor. No revision surgery was needed within the follow up period. Range of motion (ROM) and grip strength did not significantly improve. Patient satisfaction was high despite imperfect results. Conclusions Minimal arthroplasty as described may provide a temporary solution for active patients with symptomatic early wrist arthritis who are not candidates for salvage wrist surgery. Longer -term follow up as well as investigation of additional stabilization procedures is necessary.
