Mau osteotomy: an alternative procedure to the closing abductory base wedge osteotomy

The authors analyzed the postoperative results of the closing abductory wedge osteotomy and the Mau osteotomy for the reduction of metatarsus primus adductus deformity in terms of radiographic position of the first metatarsal. A review of 21 Mau osteotomies was performed. Data were collected on preoperative and long-term postoperative x-rays to evaluate first metatarsal shortening and elevation.
