A Comparison of with and without in the Fixation of Distal Chevron Osteotomies for Hallux Valgus

무지 외반증 환자의 원위 갈매기형 절골술시 절골면 고정유무에 따른 치료결과 비교

Purpose: The distal chevron osteotomy has gained popularity for the mild to moderate hallux valgus, but necessity of fixation is controversy. No fixation of distal chevron osteotomy cause instability, but fixation has problem which has pin site infection and irritability, extension of operation time, discomfort of rehabilitation. So, the author was going to analyse and compare with and without in the fixation of distal chevron osteotomy. Materials and Methods: Between 2004 and 2005, a total 18 patients (20 feet) following with and without in fixation of distal chevron osteotomies. The fixation group (A) was performed for the treatment of 10 patients (10 feet) and no fixation group (B) was done to 8 patients (10 feet). Results: On group A, the mean first MTP (metatarsophalangeal) angle corrected $17^{\circ}$ pre-operatively to average $29^{\circ}$ (range; $20-37^{\circ}$) and the mean first IM (intermetatarsal) angle corrected $10^{\circ}$ pre-operatively to average $15^{\circ}$ (range; $9-18^{\circ}$). On Group B, the mean first MTP angle corrected $16^{\circ}$ pre-operatively to average $29^{\circ}$ (range; $18-33^{\circ}$) and the mean first IM angle corrected $7^{\circ}$ pre-operatively to average $13^{\circ}$ (range; $9-16^{\circ}$) (P>0.05). Clinical results, based on AOFAS score showed an improvement in the overall results. Conclusions: Comparing the clinical and radiographic results of the distal chevron osteotomies no difference in with and without fixation of distal chevron osteotomies.
