Bunion correction surgery

A bunion (hallux abducto valgus) is a deformity cause by the big toe turning towards the other toes. This deformity is often associated with a painful hammer toe deformity. A bunion is a structural dysfunction of the foot, not an excess lump of bone. Bunions are significantly more common among women than men. A number of factors can contribute to the deformity. Particularly in women, bunions may develop as a result of excessive use of narrow and high-heeled shoes. More than half of the patients are also found to have a genetic disposition to bunions. Congenital or acquired foot deformities and problems such as calf tightness can make a person susceptible to bunions.

Toe splints, toe separators, insoles, etc. can help relieve the symptoms. However, the deformity itself can only be corrected through surgery. The planning of the procedure involves determining the causes of the deformity and selecting a surgical technique that suits the patient. Bunion surgery can be performed using different techniques. A thorough clinical examination and high-quality X-ray images of the foot are essential to the planning. Typically, the procedure involves shortening and realigning the big toe bone and repairing the joint capsule. The cut-off line and the type of repair procedure are selected from case to case. The shortened bone is fixed with screws, plates or pins.

After the procedure, the patient is required to wear a toe splint, and sometimes also a special shoe, for six weeks. During this time, the toes and the forefoot must not be subjected to strain. The patient is also not allowed to drive during this time.  The stitches are removed after two weeks. During the follow-up visit six weeks after the procedure, X-rays are taken to confirm that the toe is stable in its new position and that new bone tissue is forming as expected. The patient needs 6-8 weeks of sick leave after the procedure, depending on the physical demands of his or her work. We recommend that you avoid activities which put intense strain on the forefoot, such as jumping and tennis, for three months after having bunion surgery.
