Title: Comparison of Plantar Pressure Distribution Between Postoperative Hallux Valgus Feet and Healthy Feet. Author: Tsujinaka S, Shima H, Yasuda T, Mori K, Kizawa M, Togei K, Neo M. Journal: Foot Ankle Int; 2019 May; 40(5):578-585. PubMed ID: 30654653. Abstract: BACKGROUND: Proximal crescentic osteotomy (PCO) in patients with moderate-to-severe hallux valgus (HV) is a well-established and effective procedure for correcting the deformity. However, there are no published studies comparing plantar pressure in postoperative HV feet with healthy feet. This study aimed to compare the plantar pressure distribution in postoperative HV feet with healthy feet. METHODS: Twenty-six patients were included in the HV group, and 24 healthy participants were included in the control (C) group. All patients in the HV group underwent unilateral PCO. After undergoing PCO, this group was defined as the OP group. All subjects were women with no significant differences in age, height, weight, and body mass index. There were no significant differences in demographic characteristics between patients in each group. We divided the subjects' feet into 8 regions and measured the peak pressure (Peak-P), maximum force (Max-F), contact time, contact area, and the force-time integral in each region. RESULTS: All parameters of the great toe were significantly higher in the OP group than in the HV group. All forefoot parameters were not significantly different between the 2 groups. No parameter of the great toe was significantly different between the OP and C groups. However, mean Peak-P and Max-F of the central forefoot were significantly higher in the OP group than in the C group. CONCLUSION: PCO can improve the plantar pressure of the great toe in patients with moderate-to-severe HV to a level similar to that in healthy subjects. LEVEL OF EVIDENCE: Level III, comparative study.[Abstract] [Full Text] [Related] [New Search]
