Chevron Osteotomy with Herbert Screw Fixation for Treatment of Hallux Valgus Deformity Results

GirişHalluks valgus 1.parmağın abduktor ve adduktor kaslarında gelişen dengesizlik sonucu meydana gelen ağrılı bir deformitedir. Chevron osteotomisi hafif ve ortaşiddette seyreden halluks valgus deformitelerin cerrahi tedavisinde etkili bir yöntemdir. Gereç ve YöntemOrtopedi ve Travmatoloji kiliniğine başvuran, hafif ve orta şiddetli ağrılı halluks valgus deformitesi olan 33 genç hasta çalışmaya dahil edildi. Herbert vidası kullanılarak distal chevron osteotomy uygulanan hastalar ortalama 18 ay (6-30 ay) takip edildi. Hastaların değerlendirilmesinde preoperative ve postoperative 12. ayda The American Orthopedic Foot and Ankle Society’s (AOFAS) hallux-metatarsophalangeal-interphalangeal skalası kullanıldı.SonuçlarPreoperatif ve postoperatif ortalama halluks valgus açıları (HVA) sırasıyla 28.93 ° ± 6.66º ve 9.48 ° ± 3.21 ° olarak ölçüldü. HVA arasındaki fark istatistiksel olarak anlamlı bulundu (p=0.0001). İntermetatarsal açı (İMA) ise preoperative dönemde ortalama 11.51 ° ± 2.41 ‘den postoperatif dönemde ortalama 7.53° ± 2.10° ‘ye düştüğü saptanmıştır (p = 0.0001). Metatarsofalanjial dorsifleksiyon derecesinde 52.48 ° ± 9.71 °’den 61.90 ° ± 10.47 °’ye yükselme gözlenmiştir (p = 0.0001). Plantar fleksiyon skorlarında ise anlamlı yükselme saptanmıştır (p = 0.0001) . Preoperatif AOFAS skoru ortalaması 43,77 ± 14.14 iken postoperatif dönemde ortalama 85.38 ± 14.34 olarak saptanmıştır (p = 0.0001).Tartışma Halluks valgus cerrahisinde Herbert vidası ile yapılan Chevron osteotomisi ile kalıcı rotasyonel ve translasyonel stabilite sağlanabilmektedir.
