BACKGROUND: To present the results of the treatment of hallux valgus with the proximal metatarsal opening wedge (PMOW) osteotomy using two different screw and plate systems. METHODS: Forty-one patients with moderate and severe hallux valgus were treated with the PMOW osteotomy between 2005 and 2009. The fixation was obtained by the Darco(®) BOW or by the Arthrex(®) LPS plate. Biplanar chevron and/or Akin osteotomy were associated according to the magnitude of distal angles. Each patient was evaluated with weight-bearing radiographs and AOFAS score. RESULTS: The HV, IM, DMA and IP angles improved by a mean of 14°, 8°, 11°, 7° respectively. The sesamoid position improved in 79% of the feet. AOFAS score improved from a mean of 50 to 82. CONCLUSION: The PMOW osteotomy is effective to correct high-level hallux valgus deformities. Both systems guarantee the stability and correction of the osteotomy site. The combination with distal procedures is advisable to correct distal angles.
