Abstract

Spinal fusion, which joins two vertebra, prevents abnormal movement of vertebras. Fusion is one of the most commonly used surgical interventions.Pseudarthrosis, however, is used to define the situation in which there is a no progression of solid fusion one year after solid fusion and the continuity of movement segments leading symptoms and clinical findings. If there is an insufficiency of obtaining fusion this may give rise to benign radiological symptoms to ongoing pain or severe neurologic deficiency. Although advancement in medicine is so fast, it is still difficult to diagnose, non-fusion with 100% accuracy (specificity and sensitivity). In this study it is mentioned how to evaluate the spinal fusion in combination of clinics and radiology.

Omurga Cerrahisinden Sonra Füzyon-Nonfüzyon"un Radyolojik ve Klinik Değerlendirilmesi

Abstract

Spinal füzyon, kemiksel birleşmeyle iki omur arasındaki anormal hareketin önlenmesi, yani iki omurun kaynaştırılmasıdır. Füzyon omurga cerrahisinin en sık yapılan girişimlerinden birisidir. Pseudoartroz ise opere edilen hareketli segmentte, solid füzyonun 1 yıl sonra gelişmediğinin dökümente edilmesi ve spinal hareket segmentinde hareketin füzyondan sonra devam etmesi ile bunun semptom ve bulgulara neden olması olarak isimlendirilir. Spinal cerrahi sonrası füzyon elde edilmesinde yetersizlik olur ise bu sadece beningn bir radyolojik bulgudan, devam eden ağrı veya ağır nörolojik defisite kadar değişebilen klinik sonuçlar doğurabilir. Tıptaki tüm gelişmelere rağmen %100 doğruluk ile (sipesifite ve sensitivite) non-füzyon teşhisi koymak zordur. Bu çalışmada spinal füzyonun klinik ve radyoloji ile birlikte nasıl değerlendirilmesi gerektiği anlatılmıştır.
