Abstract
Aims Pedobarography has improved the understanding of load transmission in hallux valgus. The aim of this study is to evaluate Pedobarography in Modified McBride procedure which transfers the deforming of adductor hallucis into a correcting force on the first metatarsal neck. Material and Methods Nineteen patients with 27 feet in total who underwent this procedure were included in this study. Average age was 49 yrs (range 28 – 73). Average follow up was 7 months (range 6–14 months). Pedobarography was performed before and after the operation using EMED SFX 6 system to record the contact area, total force, peak pressures and contact time for total foot, great toe and areas of foot medial to gait line. Results Pedobarographic measurements showed a statistically significant improvement in the contact area of the great toe 7.4 cm preoperatively to 8.7 cm postoperatively (17.5%, p < 0.001) and reduction in peak pressures of the great toe from 67.5 N/cm to 48 N/cm (29%, p < 0.001) and the total foot from 89 N/cm to 82 N/cm (8% p < 0.05). Conclusion We conclude that Pedobarography demonstrates the normalisation of forces in the foot following Modified McBride Procedure.
