Öz

Spine fixation is required in cases such as congenital spinal curvatures, vertebral fractures, sagittal collapse over time, painful kyphosis, and bone load due to tumors. Although there are many methods in the literature, the most commonly used spine fixation method is the fixation with pedicle screws. In these cases, it is known that pedicle screws are used frequently in the body. In this study, how the radiological exposure of the pedicle screws in the vertebral column that dose was evaluated by simulation methods. First, the elemental analysis of the pedicle screw was analyzed via Scanning Electron Microscopy (SEM) equipped with the Energy Dispersive X-ray Spectroscopy (EDS). Then, the elemental compositions of the pedicle screw obtained were used for simulation codes. subsequently, the half-value thickness and the attenuation coefficient calculations were conducted for the pedicle screw and vertebral column. Both XCOM software and MCNP (Monte Carlo N-Particle) simulation code were used to obtain photon interaction parameters within the energy range of 60-250 keV.

Teşekkür

The authors very much appreciate the support to the density value of pedicle screw by Kayahan Medical, Turkey for providing Orion brand pedicle screw.

Konjenital omurga eğrilikleri, vertebra kırıkları, zamanla sagital kollaps, ağrılı kifoz, tümörlere bağlı kemik yükü gibi durumlarda omurga tespiti gerekir. Literatürde birçok yöntem olmasına rağmen en sık kullanılan omurga sabitleme yöntemi pedikül vidaları ile sabitlemedir. Bu durumlarda vücutta pedikül vidalarının sıklıkla kullanıldığı bilinmektedir. Bu çalışmada vertebral kolondaki pedikül vidalarının radyolojik maruziyetinin simülasyon yöntemleri ile nasıl değerlendirildiği araştırılmıştır. İlk olarak, pedikül vidasının element analizi, Enerji Dağıtıcı X-ışını Spektroskopisi (EDS) ile Taramalı Elektron Mikroskobu (SEM) ile analiz edildi. Daha sonra elde edilen pedikül vidasının elementel bileşimleri simülasyon kodları için kullanılmıştır. Daha sonra pedikül vidası ve vertebral kolon için yarı değer kalınlık ve zayıflatma katsayısı hesaplamaları yapılmıştır. Enerji aralığı 60-250 keV olan foton etkileşim parametrelerini elde etmek için hem XCOM yazılımı hem de MCNP (Monte Carlo N-Particle) simülasyon kodu kullanılmıştır.
