Purpose: To present clinical results of proximal first metatarsal opening wedge osteotomy and low profile plate fixation in hallux valgus deformity. Materials and Methods: Thirty-two patients (39 feet) underwent surgery for hallux valgus deformity. Fourteen patients (18feet; Group A) underwent proximal first metatarsal opening wedge osteotomy fixed with low profile titanium plate (Arthrex),and 18 patients (21 feet; Group B) underwent proximal chevron osteotomy with two K-wires. Improvement in hallux valgus angle (HVA), 1, 2 intermetatarsal angle (IMA), range of motion of 1st metatarsophalangeal joint, VAS score, and the length of first metatarsal on weight-bearing radiograph were evaluated preoperatively and at final follow-up. Results: HVA improved from 36.2±6.6 degrees to 11.7±5.1 degrees, and 1, 2 IMA improved from 15.7±2.6 degrees to 7.2±1.9 degrees. VAS score improved from 7.2±1.2 to 1.4±0.9. There were no significant differences clinically and radiologically. Conclusion: Proximal first metatarsal opening wedge osteotomy with stable fixation using low profile plate may be an effective surgical option for correction of hallux valgus deformity.
