Comparison of bioabsorbable pins and Kirschner wires in the fixation of chevron osteotomies for hallux valgus.

Abstract

A retrospective review of the medical records and radiographs of 32 consecutive patients, totaling 52 extremities with chevron osteotomies for hallux valgus, was conducted to compare K wire fixation with absorbable (poly-p-dioxanone) pin fixation. Each group comprised 21 feet, with a mean clinical follow-up of 35.6 months (25.6-50.5 months) in the K wire group and 23.1 months (13.7-28.8 months) in the absorbable pin group. Demographics as well as final clinical follow-up scores (hallux-metatarsophalangeal-interphalangeal scale and visual analogue scores) were similar in both groups. Postoperative hallux valgus and intermetatarsal angles were similar in both groups. No complications, such as osteolysis for inflammatory sinus formation, occurred in the absorbable pin group. Two patients in the K wire group had a malunited osteotomy and two patients had a retained K wire at final follow-up. Our experience suggests that poly-p-dioxanone pins are at least as effective as K wires, and the previous reports of inflammatory sinus formation and osteolysis are not a significant concern in the fixation of chevron osteotomies for hallux valgus.
