Quantitative baropodometry can detect differences in hallux valgus deformity with similar radiographic measurments

Abstract

Objective: The aim was to explore differences in dynamic baropodométric preoperative measurements in patients with hallux valgus operated with the same minimally invasive technique but with different postoperative results. Methods: Seventeen cases with elevated first metatarsal head after surgery and 52 controls without elevation were identified and were compared the baropodometric measurements with a force platform Tekscan®. Results: The medium in 17 cases and 52 controls were 3.7 versus 2.7kgs maximum pressure in 1st metatarsal (p=0.0157), 2.9 versus 2.1kg of average pressure (p=0.0069) and 1 versus 0.9 seconds, speed (p=0.0918). Conclusion: The main contribution of this exploratory study was to describe the relationship of preoperative baropodometric measurements and the elevation of the first metatarsal head after hallux valgus surgery.
