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.
