    Abstract:
    UNLABELLED: The deformity of hallux valgus is multifactorial, albeit primarily in the transverse plane. In order to achieve an anatomic correction, a surgical technique must be able to address the deformity with consistent outcomes. The purpose of the present study was to evaluate a technique designed to reposition the first metatarsal bone, metatarsophalangeal joint, and sesamoid apparatus in an anatomic and biomechanical corrected position for correction of hallux valgus deformity. This article is a retrospective analysis of 36 operations performed in 28 individuals between January 1995 and December 2005. Each case involved the use of a modified-Mau osteotomy combined with a Reverdin osteotomy to correct the first intermetatarsal and proximal articular set angles. Comparisons were made between the preoperative and postoperative first IM angle, proximal articular set angle, tibial sesamoid position, and hallux valgus angle. The median follow-up period was 48 (range 12-121) months from the date of surgery. The median reduction of the 1-2 intermetatarsal angle was 12 degrees (range 5-19 degrees). The median decrease for the hallux valgus angle was 20.5 degrees (range 0-63 degrees). The median reduction in the PASA was 16 degrees (range 4-69 degrees). The median decrease in the tibial sesamoid position was 5 (range 2-6). These differences were all highly statistically significant (P < .001), and all of the patients experienced a high rate of satisfaction (median AOFAS score 95 [range 70-95]) following the intervention. The Mau-Reverdin double osteotomy appears to be an effective intervention for the radiographic and clinical correction of hallux valgus. LEVEL OF CLINICAL EVIDENCE: 4.
