Bunion surgery is a procedure in which overgrown, inflamed bones and tissues that surround the big toe joints, also referred to as bunions, are surgically removed, realigned or reshaped to relieve foot discomfort, according to Johns Hopkins Medicine. The type of surgery performed depends on the extent of the condition.
Bunion surgery options include arthrodesis procedures in which inflamed joint surfaces are surgically removed and exostectomy procedures that remove the overgrown bony lumps on the big toe, according to the American Academy of Orthopaedic Surgeons. Additional procedures include surgical joint realignment and tendon repair procedures. In most cases, bunion surgery is an outpatient procedure that is typically performed under local anesthesia.
