PURPOSE: We conducted this study to examine the clinical results of the proximal metatarsal wedge osteotomy using a single screw fixation and the distal soft tissue procedure in patients with moderate to severe hallux valgus deformity. MATERIALS AND METHODS: Between February 2002 and February 2004, we performed these procedures on 12 patients (15 cases). The 6 cases of all patients had mild to moderate instability in the first MTC (metatarsocuneiform) joint. We estimated the clinical outcomes, the radiological findings and complications. RESULTS: AOFAS score was improved from preoperative 41.5 points to 87.7 points lastly on average. The mean correction angle of HVA and IMA was 23.8 degrees and 6.6 degrees, respectively. The mean position of tibial sesamoid was 2.67 before surgery and 0.87 after surgery. The mean shortening of the first metatarsal bone was 3.07 mm after surgery. There was no pain and complications on the first MTC joint except the breakage of screw in one case and instability of the first MTC joint was improved postoperatively. CONCLUSION: We obtained good clinical and radiographic outcomes in our series. So, proximal metatarsal wedge osteotomy using a single screw fixation and distal soft tissue procedure seems one of the good surgical treatments for moderate hallux valgus deformity.
