Cavus Foot Surgery

You have been advised to have surgery on your foot to correct a high arch, known also as a Cavus foot.  There are many different smaller procedures that can be used to correct this deformity and often more than one or even several of these may be used at the same operation.  Below are the main principles that will apply to your operation.

  • The procedure will correct the high arch of your instep
  • You are likely to have more than one scar
  • The operation will often involve surgery on the tendons as well as bones of your foot
  • It is common to need a bone graft procedure.  This involves taking a wedge shape of bone from your pelvis and inserting this into a cut in one of the bones in the middle of the foot
  • The pelvis can be reasonably painful after the operation but appropriate pain relief will be given to you
  • Your foot will be placed in a plaster slab from the toes to below the knee
  • You will not be allowed to take weight through your foot for 6 weeks after surgery
  • You will therefore need to use aids such as crutches, a frame or wheelchair
  • The wound will be checked 2 weeks after the operation when a full plaster will be applied.  You can rest this plaster on the floor but you will still not be able to take weight when walking
  • At 6 weeks after surgery the plaster will be changed for a cast that allows you to take half your body weight through it.  This is worn for 6 weeks
  • The total time in a cast is therefore 12 weeks after this type of surgery
  • Once the cast is removed an x-ray will be taken to check on the healing
  • Physiotherapy will be required to aid rehabilitation
  • The end point of recovery is usually about 9 months after surgery although function will be good for the last 3 months or so
  • As with any operation there are risks associated with this surgery.  Infection occurs in about 1%. Minor nerve injury may occur resulting in pins & needles or numbness over an area of the foot, this is usually temporary.  Delayed healing to the wounds or bones may occur.  Thrombosis of the veins in the leg happens occasionally
  • The majority of patients undergoing this type of surgery have a good result and are pleased with the outcome
