Treatment of Metatarsus Adductus in Adults With First Metatarsal Cuneiform Arthrodesis and Closing Osteotomy of the Cuboid

Nine adult patients, between 2001 and 2004, diagnosed with metatarsus adductus were treated surgically with a closing osteotomy of the cuboid and a first metatarsal cuneiform arthrodesis. All patients were followed over the course of their complete postoperative treatment period. Preoperative and postoperative radiographic metatarsus adductus angles were analyzed. Preoperative metatarsus adductus angles ranged between 25 and 40 degrees, whereas postoperative angles ranged between 0 and 16 degrees. These results show that the closing osteotomy of the cuboid in conjunction with a first metatarsal cuneiform arthrodesis has the capacity to correct metatarsus adductus deformity, and stabilize the medial column of the forefoot.
