Abstract

Giriş

Halluks
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 Yöntem

Ortopedi
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.

Sonuçlar

Preoperatif
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.
