Cavovarus Deformity Surgery
The term “cavovarus” refers to a foot with an arch that is higher than normal, and that turns in at the heel. This is a deformity that tends to worsen gradually over time. Depending on the age of the patient and the degree of deformity and stiffness, treatment options may range from supportive care with bracing, to surgical treatment for soft tissue releases, tendon transfers, and possibly reshaping or fusion of the bones and joints.
Cavovarus Deformity FAQ
What Causes Cavovarus Deformity?
Cavovarus foot deformity is often caused by weakness in the peroneal muscles and, in some cases, the small muscles in the foot. These imbalances contribute to the abnormal shape and function of the foot.
What Are the Symptoms of Cavovarus Deformity?
Symptoms of cavovarus deformity may worsen as the condition progresses. Common symptoms include:
- Increasing pain at the ankle due to recurrent sprains
- Painful calluses at the side of the foot or base of the toes
- Difficulty with shoe wear
What Are the Treatment Options for Cavovarus Deformity?
Nonsurgical Treatment
Treatment depends on the severity of the condition and any associated pain. In mild cases, nonsurgical options include:
- Using orthotics or custom shoes to support and protect the foot, reducing pressure on affected areas
- Implementing a regular skin care routine to manage corns and calluses
- Engaging in a foot and ankle conditioning program(opens in a new tab) to improve strength and flexibility
Surgical Treatment
Surgery may be recommended in severe cases, particularly if pain persists or the arch continues to increase. Surgical options can include:
- Releasing contracted soft tissues
- Performing tendon transfers to rebalance the foot
- Conducting osteotomies to reshape the foot
- Fusing joints to realign and stabilize the foot in a corrected position
