We reviewed 33 consecutive Mau-Reverdin osteotomies in 23 patients performed for correction of hallux abducto valgus from November 2010 to May 2013. All patients were followed up and evaluated for a mean of 401 days and median of 360 days after surgery. In each foot, the preoperative first intermetatarsal angle, hallux abductus angle, and proximal articular set angle were obtained. The mean correction of these angles was as follows: intermetatarsal angle 10.5° ± 3.31°, hallux abductus angle 24.4° ± 8.8°, and proximal articular set angle 28.39° ± 11.2°. Furthermore, we evaluated for metatarsus elevates, and no statistically significant first metatarsal elevation was present in any of the 33 feet (p < .0001). Additionally, 21 of the 33 feet (63.6%) were available for first metatarsophalangeal joint American Orthopaedic Foot and Ankle Society scale score evaluation. The mean preoperative score was 25.5 ± 16.7. After correction, the mean American Orthopaedic Foot and Ankle Society scale score had increased to 95.4 ± 5.7. All these differences were statistically significant (p < .0001), and the patients had a very high level of satisfaction. In all 33 feet, no deep infection, malunion, nonunion, avascular necrosis of the first metatarsal, or hardware failure developed. One patient developed hallux varus deformity. The Mau-Reverdin osteotomy is a very effective and reproducible procedure that successfully corrects large bunion deformities and provides patients with a high level of satisfaction and a low complication rate.
