Hallux valgus patients exhibit increased foot pressure on the small toe and reduced overall foot contact area. These findings suggest a link between altered pressure distribution and metatarsalgia in hallux valgus deformities.

Area of Science:

  • Biomechanics
  • Podiatry
  • Orthopedics

Background:

  • Hallux valgus, a common foot deformity, affects foot pressure distribution.
  • Understanding these changes is crucial for managing associated pain like metatarsalgia.

Purpose of the Study:

  • To analyze solar pressure zones in patients with hallux valgus compared to healthy individuals.
  • To investigate the relationship between altered pressure patterns and metatarsalgia.

Main Methods:

  • Utilized the EMED Gait Analysis System to assess plantar pressure.
  • Compared pressure data from 66 hallux valgus patients and 60 control subjects.

Main Results:

  • Hallux valgus group showed significantly increased pressure in the small toe region and near the metatarsophalangeal joint.

Related Experiment Videos

  • Normal subjects displayed increased pressure in the first four metatarsal and heel regions.
  • Hallux valgus patients generally had smaller foot contact areas.

    • Conclusions:

    • Altered pressure distribution, particularly increased pressure on the small toe and reduced contact areas, may cause metatarsalgia in hallux valgus.
    • This study provides biomechanical insights into the etiology of metatarsalgia in hallux valgus.
