The Clinical Results of the Proximal Opening Wedge Osteotomy Using a Low Profile Plate in Hallux Valgus: Comparison with Proximal Chevron Osteotomy Fixed with K-wires / 대한족부족관절학회지

ABSTRACT

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 (18 feet; Group A) underwent proximal first metatarsal opening wedge osteotomy fixed with low profile titanium plate (Arthrex(R)), 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.
