Cavus foot — pes cavus and cavovarus
In a cavus foot, the arch is excessively high and load is concentrated on the heel, forefoot and often the outer border. The deformity may be flexible or rigid and can sometimes reflect an underlying neurological condition.
Clinical context
What you should know
The cause may be idiopathic, post-traumatic or neuromuscular. Asymmetry, progression, weakness and family history may indicate the need for neurological assessment.
Correction aims to achieve a plantigrade foot and a more balanced distribution of pressure, not simply to reduce the appearance of the arch.
First step
Consultation and assessment
Assessment covers gait, hindfoot flexibility, muscle strength, sensation, tendon function and ankle stability. Weight-bearing radiographs define alignment.
Neurological tests, MRI or CT are selected according to the suspected cause and the procedures being considered.
Stepwise treatment
Options are chosen according to the diagnosis and treatment goal
Conservative treatment
- footwear with room for the toes and adequate cushioning
- orthoses that redistribute pressure and support a flexible alignment
- rehabilitation for movement, strength and balance
- protection of pressure areas and skin monitoring, especially when sensation is reduced
Medication, injections and devices each have their own indications and contraindications. They are not recommended automatically and do not replace a diagnosis or monitoring of the response.
When surgery is considered
Correction may combine soft-tissue releases, tendon transfers and osteotomies; rigid or arthritic deformities may require fusion. The cause, flexibility and muscular imbalance determine the combination.
Do not delay
Signs that require prompt assessment
- progressive weakness, falls or new numbness
- a wound in a pressure area or signs of infection
- persistent bone pain with a suspected stress fracture
In an emergency or if symptoms are severe, call 112 or go to the nearest emergency department.
Frequently asked questions
Concise answers, without blanket promises
Can a cavus foot have a neurological cause?
Yes. This is why strength, sensation, symmetry and progression are assessed. Neurological evaluation is sometimes indicated before planning reconstruction.
Can one operation correct every type?
No. Procedures are combined according to flexibility, alignment, tendon function and the joints affected. A standard plan would ignore the individual mechanism of the deformity.
