A cavus foot or a high-arched foot refers to a condition that can vary from a slightly high arch to a severe deformity. Cavus foot can lead to symptoms such as pain and instability. The condition may be inherited or associated with neurological disorders or other conditions.
Cavus foot reconstruction is performed to reduce pain and increase stability in the foot. It is indicated when conservative treatment including orthotic appliances, shoe modifications, and bracing does not resolve the symptoms.
Cavus foot reconstruction involves various surgical techniques:
- Soft tissue surgery:
- Tendon release in case of over pull from the muscles
- Tendon transfer to correct a deformity in the ankle joint
- Achilles tendon lengthening to reduce the tension from the calf muscle, and
- Release of a tight plantar fascia, a fibrous band that runs along the bottom of the foot.
- Removal of bone (osteotomy) from the heel, toes or other parts of the foot
- Joint fusion in case of severe joint deformity and pain
Recovery following cavus foot reconstruction takes approximately 6 weeks for the bone to heal and total recovery may last 8-12 weeks. The post - surgical protocol varies amongst patients, and may be strict non-weightbearing for 6 weeks after the surgery. The decision to initiate an early weight-bearing program depends on the stability of the fixation used to correct the problem. In any case, do not put weight on the foot until instructed by your surgeon.
As with any surgical procedure, complications can occur and include the risk associated with anaesthesia, bleeding, blood clots, infection, damage to surrounding blood vessels and nerves.
