While podobarometric techniques have been applied to the study of pressures in Hallux Valgus (HV), little is known about its clinical and radiological
determinants. So, the aim of the present study was to determine the plantar
pressure pattern in participants with mild HV, comparing to a control group, and
their clinical and anthropometric determinants.
Biofoot/IBV((R)) in-shoe system
was used to evaluate 79 participants with mild HV. Computerized measurements of
the 1st intermetatarsal angle (IMA) and the hallux abductus angle (HAA) were made
on antero-posterior radiographs. The clinical outcome was assessed using the
AOFAS score. The dependent baropodometric variables and the independent clinical
and anthropometric variables were subjected to a multiple regression analysis. In
both groups, the highest average pressure was in the 2nd metatarsal head (MTH).
The mean pressure under the Hallux was significantly higher in HV group
(controls, 146.5+/-92.5kPa; HV, 328.5+/-113.2kPa; p<0.001). An 18.6% of average
pressure under the 1st MTH was accounted for pain, first ray alignment and total
AOFAS score. Variations of the HAA explained 26.8% of the mean Hallux pressure.
Women with mild HV present with pathologically increased pressure under the
Hallux, which is caused by the altered alignment of the first ray. Pain and
clinical result were associated with the pressure under the 1st MTH and the remaining variables were only moderate predictors of dynamic plantar pressures.
