Hallux varus--a study of thirty cases
The Journal of Foot Surgery
|September 1, 1984
Summary
Hallux varus, a foot deformity, is common in unshod populations, particularly congenital types. Untreated cases progress, and middle-aged individuals can develop idiopathic hallux varus, linked to not wearing shoes.
Area of Science:
- Orthopedics
- Podiatry
- Human Anatomy
Background:
- Hallux varus, a deviation of the big toe, is traditionally considered uncommon.
- This study challenges that notion by observing its prevalence in populations that do not wear shoes.
Purpose of the Study:
- To investigate the prevalence and types of hallux varus in unshod populations.
- To identify potential causes and progression patterns of hallux varus, particularly in relation to footwear habits.
Main Methods:
- Analysis of 30 cases of hallux varus.
- Observation of deformity progression and association with age and footwear.
Main Results:
- Congenital hallux varus is the most frequent type, presenting in primary, secondary, and teratogenic forms.
- Untreated congenital hallux varus progresses with age in unshod individuals.
- Idiopathic hallux varus can develop in middle-aged, unshod individuals.
- Severe hallux varus correlates with medial deviation of adjacent toes.
- Foot structure (first metatarsal length, intermetatarsal angle, first metatarsal head shape) does not appear causative.
Conclusions:
- Hallux varus is more common than previously thought, especially in unshod populations.
- The lack of footwear is a significant factor in the progression of congenital hallux varus and the development of idiopathic hallux varus in middle age.
