Abstract
BACKGROUND: Hallux valgus is a common condition that affects the forefoot. A large number of procedures are described for managing this condition. Mitchell's osteotomy and its modifications are being widely used for treating hallux valgus. However, most of the studies describe the results from the developed world. We present results of the classic Mitchell's osteotomy in hallux valgus in Indian subcontinent. MATERIALS AND METHODS: Forty eight adult patients (including 12 bilateral ones) in the age range of 18-60 years with hallux valgus were managed with the classic Mitchell's osteotomy. Pain over the bunion was the reason for surgery in 53 of 60 feet and cosmesis in the remaining 7 feet. Patients with hallux valgus angle more than 20 degrees and not responding to a trial of conservative treatment were included. Patients having metatarsophalangeal (MTP) joint osteoarthritis (Grade II and higher), hallux rigidus, rheumatoid arthritis, and with subluxation of MTP joint were excluded from the study. Further, patients with first metatarsal more than 3 mm shorter than second metatarsal were also excluded. RESULTS: The average follow-up period is 3 yrs (range 18months - 6yrs). About 55 feet (83%) were painless after surgery. Forty-two (70%) patients were happy with the cosmetic results of the surgery. Metatarsalgia was the reason for dissatisfaction with the procedure in five patients. The average correction of hallux valgus and the intermetatarsal angles achieved was 19.7 degrees and 6.9 degrees , respectively. Using the Broughton and Winson scoring system, 37 (61.7%) feet had excellent results, 18 (30%) had good, and five (8.3%) feet had a poor results. CONCLUSION: The classic Mitchell's procedure is a simple procedure and gives good cosmetic and radiological results.
