Abstract:

Interposition arthroplasty reportedly improves outcomes after traditional salvage procedures for advanced hallux rigidus. We hypothesized this procedure can provide pain relief and satisfactory function with few complications. We examined 18 patients with severe articular cartilage loss who received 21 interposition arthroplasties. The patients a mean age was 56 years. They had a mean followup of 38 months. All patients had substantial loss of articular cartilage when examined intraoperatively. Patients were evaluated using the American Orthopaedic Foot and Ankle Society and Short Form-36 scores. All 18 patients had pain relief, and 17 of 18 patients said they would have the procedure again. The mean postoperative increase in range of motion of the first meta-tarsophalangeal joint was 37[degrees]. The mean American Orthopaedic Foot and Ankle Society and Short Form-36 scores were 78.4 and 96.3, respectively. The complication rate was 6%. Results of our study indicate that interposition arthroplasty relieves pain and restores motion in patients with advanced hallux rigidus and may offer a reliable option to fusing the joint.
