Preoperative planning and intraoperative technique for accurate realignment of the Dwyer calcaneal osteotomy.

The Dwyer calcaneal osteotomy is an effective procedure for the correction of calcaneal varus deformity. However, no intraoperative method has been described to determine the amount of bone resection. We describe a simple intraoperative method for assuring accurate bone resection and measure the realignment effects of the Dwyer calcaneal osteotomy.
