We have reviewed a single surgeon's experience with isolated talonavicular fusion in 16 patients with talonavicular arthritis. Fixation was either by staples or screws. Fifteen solid unions were achieved in the 16 patients who were followed (mean: 51 months). The average Ankle-Hindfoot Scale improved from 77.2 preoperatively to 92.9 postoperatively (p < 0.001). Subjectively, 15 patients were satisfied and one patient dissatisfied with the results. Further osteoarthritis in the adjacent joints was noted in five patients. We concluded that isolated talonavicular fusion is an effective method of treatment of talonavicular arthritis regarding pain relief and functional improvement. Though osteoarthritis was found in some adjacent joints postoperatively, the results were still satisfactory.

On the basis of our result, we recommend that type II and type III fractures be treated with open reduction and internal fixation. Despite the results of type IV fractures being significantly worse than that of type II and type III fractures, we recommend open reduction and internal fixation for type IV fractures to restore the hindfoot architecture and the subtalar joint, if possible. When the disrupted subtalar joint is so comminuted that it is beyond the surgeon's ability to reconstruct, primary subtalar arthrodesis should be performed in addition to open reduction and internal fixation.

From 1988 to 1995, 96 patients (161 feet) underwent a modified Mitchell distal metatarsal osteotomy performed for mild-to-moderate hallux valgus. On AP x-rays of the standing foot, the average intermetatarsal angle was corrected from 15 degrees to 9 degrees, and the first metatarsophalangeal angles were corrected from an average of 41 degrees to 15 degrees. Criteria for evaluation of clinical results included relief of pain, appearance of foot, and shoe wear. After an average follow-up of 38 months, the overall satisfaction rate was 92.5%. Complications included 13 pin tract infections, two delayed unions, and two correction losses. The most common late sequela was transfer metatarsalgia of the lesser toes, which occurred in 20 feet (12.4%), leading to some dissatisfaction. The Mitchell osteotomy can be used on cases with less than 20 degrees of intermetatarsal angle, offering a stable construct with easy postoperative care.
