Summary
Hallux valgus patients exhibit abnormal foot motion, including excessive joint rotation and limited toe movement, unlike healthy individuals. This study highlights a multi-segment foot model
Area of Science:
- Biomechanics
- Orthopedics
- Podiatry
Background:
- Hallux valgus (HV) is a common foot deformity.
- Understanding its biomechanical impact is crucial for effective treatment.
Purpose of the Study:
- To analyze and compare multi-segment foot motion between hallux valgus patients and healthy subjects.
- To evaluate the utility of a 9-segment foot model in diagnosing foot conditions.
Main Methods:
- Multi-segment foot motion analysis was conducted.
- The 9-segment foot model was employed.
- HV patients' foot motion was compared to that of normal subjects.
Main Results:
- No significant hindfoot motion differences were observed between groups.
- HV patients displayed hyperexternal rotation of the talocrural joint.
- Excessive subtalar joint eversion and reduced hallux metatarsophalangeal/medial metatarsophalangeal joint motion were noted in HV patients during specific stance phases.
Conclusions:
- The 9-segment foot model is a feasible tool for diagnosing and treating various foot diseases.
- Further research with larger cohorts is recommended to validate findings.
- Abnormal foot kinematics in HV patients suggest potential targets for therapeutic interventions.
