Cresentic Osteotomy Bunion Correction

Edited by Sam Dellenbaugh, MD


A Cresentic osteotomy is a surgical procedure to correct a moderate or severe bunion deformity.  It is one of many different types of bunion procedures that may be performed. The crescentic osteotomy involves an incision on the inside (medial aspect) of the forefoot, and then a semicircular bone cut (osteotomy) through the base of the 1st metatarsal (the bone that leads to the great toe).  The two parts of the cut bone are then rotated to change the position of the bone and help correct the bunion deformity. The cut bone fragments are then stabilized with screws or a plate. This procedure is usually combined with a 1st MTP joint capsularraphy (tightening of the soft tissue on the inside of the big toe).


As this procedure involves cutting the bone, about 6 weeks of limited weight-bearing is required to allow the bone to heal.
