Abstract

Purpose: The pedicle anatomy is the most important point during lumbar pedicle screw fixation. The pedicle measurements provide the spine surgeon additional useful information in order to place safer and stronger pedicle screws. Although several studies of pedicle anatomy have been published, pedicle wall thickness has not been studied before such as radiologic anatomy in Turkish people. Methods: In this radio-anatomical study, we aimed to measure the medial and lateral cortical walls of each lumbar pedicle to obtain quantitative data and to demonstrate if there are any differences between lateral and medial pedicle walls. A total of 500 pedicle in 50 patients (mean age: 45.2) were measured from L1 to L5 by computed tomography (CT) scanning. We investigated and measured both lateral and medial aspects of pedicle walls by thin-section CT. Results: In all levels, the medial wall of the pedicle was found to be thicker than lateral wall (p<0.001). Conclusion: Medial pedicle wall is thicker than lateral wall in the lumbar pedicles in the Turkish population. The medial wall should not purchase to preserve the nerve root. It is also important to preserve the integrity of this wall for biomechanical stability.

Özet

Amaç: Lomber pediküler vida ile fiksasyonunda pedikül anatomisi çok önemlidir. Güçlü ve emniyetli pedikül vidalaması için pedikül ölçümü önemli bilgi vermektedir. Birçok pedikül anatomisi ile ilgili çalışma olmasına rağmen Türk nüfusunda bugüne kadar yapılmışbir radyolojik anatomi çalışması yoktur. Gereç ve yöntem: Bu radioanatomik çalışmada, her lomber vertebranın iç ve dışpedikül duvarının kalınlıkları ölçülerek arasındaki kalınlık farkının ölçülmesi amaçlanmıştır. Toplam 50 hastanın (ortalama yaş45.2) L1-L5 arası 500 pedikülünün lateral ve medial duvarları ince kesit tomografi ile ölçülerek incelenmiştir. Sonuç: Tüm L1-L5 vertebralarda medial duvar, lateral duvardan daha kalın bulunmuştur (p<0.001). Tartışma: Türk toplumunda lomber pedikül medial duvar kalınlığı laterale göre daha kalın bulunmuştur. Pedikülün medial duvarı sinir köklerinin korunması için feda edilmemelidir. Biyomekanik stabilite için bu duvarın bütünlüğü ayrıca önemlidir.
