title: The modified McBride procedure: clinical, radiological, and pedobarographic evaluations.
abstract: Nineteen patients (27 feet) with symptomatic hallux valgus who underwent modified McBride procedure were studied prospectively. The outcome measures included preoperative and postoperative American Orthopaedic Foot and Ankle Society's Hallux Metatarsophalangeal-Interphalangeal scoring, weight-bearing radiographs, and pedobarography using the EMED-SF*6 System. The average patient age was 49.7 years, and all patients were women. The average follow-up was 7 months. Results showed an average improvement in rating scale score from 53 to 87/100, in the hallux valgus angle from 32 degrees to 15 degrees, and in the first intermetatarsal angle from 15 degrees to 10 degrees. Pedobarographic analysis showed a statistically significant increase in the contact area of the hallux by 17.5% (P<.001), with a reduction of peak pressures of the hallux by 29% from 67.5+/-29.5 N/cm2 to 48+/-34 N/cm2 (P<.001; confidence interval, 9.887, 29.233) and the total foot by 8% from 89+/-26 N/cm2 to 82+/-25 N/cm2 (P<.05; CI, 0.727, 14.900). The overall satisfaction rate was 96%. We conclude that the modified McBride procedure has a role in patients with passively correctable hallux valgus and a supple metatarsocuneiform joint.
