Özet
Posterior yaklaşım yoluyla, C1 vertebrasına yerleştirilecek ideal vida boyunu belirlemek amacıyla 30 adet kuru atlas vertebrası üzerinde morfometrik ölçümler yapılmıştır. Aynı zamanda tüm vertebralara 3D BT çekilerek, radyolojik tetkikler üzerinde uzunluk ve açı ölçümleri yapıldı.Daha önce C1 vidalama için yapılan morfometrik çalışmalar titizlikle incelendi. İdeal vida boyunu belirlemek amaçlı olarak, literatür taramasının sonuçlarına göre, daha önce ölçülmemiş 2 uzunluk parametresi üretilmiştir. Bu parametrelerden ilki, sagittal plandaki ideal vida uzunluğu, sağ tarafta ortalama 17,80 mm ve sol tarafta ortalama 18,72 mm olarak ölçülmüştür. İkinci parametre olan vertikal plandaki ideal vida uzunluğu sağ tarafta ortalama 19, 06 mm, sol tarafta ortalama değer ise 19,26 mm olarak saptanmıştır. Görüldüğü gibi, bu iki ölçüm parametrelerinde aralık değerleri arasındaki farklar 5,65 mm ile 9,25 mm arasında değişmektedir. Yapılan ölçümler ve literatür taramasının sonuçlarına göre, C1 yan kitle vidalama tekniğinde standart bir vida boyu yoktur. Vida boyu her bireye göre değişmektedir. C1 yan kitle vidalaması yapacak cerrahın operasyon öncesi yapacağı servikal BT tetkiki ile uygun vida boyunu hesaplayarak, uygun ölçülerde vida kullanması gereklidir.
Morphometrical analysis of 30 dry stored atlas (C1) vertebrae was performed in order to determine the appropriate length of the screws to be placed on the atlas via posterior approach. In addition, a 3D CT scanning was performed on all samples and angles and lengths were measured on radiological data derived from CT scans.The previous morphometric studies carried out on C1 screw fixation were meticulously reviewed. The literature review has revealed that two non-assessed measurement parameters akin to the ideal screw length have been generated in this study. The first of these parameters, the length of the screw in the saggital plane, has been found 17.8 mm on right and 18.72 mm on left sides. The length of the screw in the vertical plane was found 19.06 mm on right and 19.26 mm on left sides. It's clear that the differences between the interval values of the two measurement parameters range between 5.65 mm and 9.25 mm at minimum. According to the measurements and the literature review carried out so far, there is not a standard screw length for C1 lateral mass screwing technique. The screw length is different for every individual. The surgeon to apply C1 lateral mass screwing must calculate the appropriate screw length via pre-operative cervical CT examinations and use the appropriate-sized screws in the operations.
