The causes of high arched feet can vary greatly. They range from neurological disorders, club foot, injury, and often times there may be no known reason. The idea behind surgery to correct this often painful condition is to bring the arch down and thereby, allow the ground pressure of walking to be more evenly distributed across the entire bottom of the foot. Over time high arch feet can cause severe plantar calluses, ulcerations broken metatarsals and even chronically sprained ankles.
I will only briefly describe the major types of procedures that are used to surgically correct the deformity. You must understand that this is a deformity that is occurring in all 3 of the cardinal planes of the body, and there is rarely only one procedure that can be done to correct the deformity.
The soft tissue surgeries usually would include a lengthening of the Achilles tendon, releasing of the plantar fascia as well as tendon transfers. These procedures are usually done in conjunction with bony procedures such as calcaneal osteotomies (to lower the heel bone and get it more under the leg itself), as well as metatarsal osteotomies. These procedures usually involve either cutting or fusion of the bones, and placement of fixation devices to allow the bones to heal. Healing time is usually at least 6-8 weeks and usually the patient must be non-weight bearing during the healing process.
These types of surgical corrections are usually reserved for the more difficult, painful and deformed feet. They can require more surgeries down the line. These procedures are usually the last resort after all other modes of treatment have been exhausted (except in children where it is usually best to treat the deformity early). There are many different degrees of high arched feet and these procedures should be left for the more extreme cases. These cases usually require a very high degree of surgical skill and should only be done by those who frequently perform these types of cases.
