Manyetik rezonans görüntüleme yöntemi ile lumbal intervertebral disklerin morfometrik değerlendirilmesi

Bu çalışma ile, sağlıklı Türk bireylerde, manyetik rezonans görüntüleme yöntemi kullanılarak, lumbal intervertebral disk yüksekliklerinde yaşa, cinsiyete ve kiloya bağlı değişikliklerin ortaya konulması amaçlandı. Toplam 305 semptomsuz kişi (131’i erkek (yaş aralığı 10-72 yaş; ortalama 36 ± 15,79 yaş) ve 174’ü kadın (yaş aralığı 10-80 yaş; ortalama 38 ± 13,37)) çalışma periyodu esnasında seçildi. Hepsi lumbal intervertebral disklerin anterior ve posterior yüksekliklerini ve disk derinliklerini ölçmek için midsagital manyetik rezonans görüntülemeye maruz bırakıldı. Disk anterior yüksekliğinde ve disk derinliğinde; genel olarak; her iki cinste ve her dekadda L1'den L5'e doğru sefalokaudal (yukarıdan aşağı) bir yükseklik artışı görülmesine rağmen disk posterior yüksekliğinde; değişken bir durum görüldüğünden herhangi bir genelleme yapılamadı. Elde edilen bilgilerin semptomatik hastalarda lumbal disklerin değerlendirilmesinde referans olarak kullanılabileceği, bu verilerin hem intervertebral disklerin geometrik modellemesine hem de biyomekanik ve ergonomik analizlere önemli katkılar sağlayacağı düşünülmektedir.

Morphometric evaluation of lumbar intervertebral discs by using magnetic resonance imaging

The aim of the present study was to reveal the changes in lumbar intervertebral disc heights in asymptomatic Turkish individuals relative to the age, gender and weight by using magnetic resonance imaging. A total of 305 asymptomatic individuals (131 males, age range 10-72 years; mean 36 ± 15.79 and 174 females, range 10-80 years; mean 38 ± 13.37) were selected during the study period. All the individuals underwent midsagittal magnetic resonance imaging for measuring the anterior and posterior heights and disc depths of all lumbar intervertebral discs. In anterior heights and disc depths of intervertebral discs, as a whole, from L1 to L5, cepalocaudal, the increases were seen in both genders and in all decades. However, it was not possible to make any generalizations for judging the variables in the posterior heights of intervertebral discs. Therefore, it was considered that the database established would eventually serve as a reference for evaluation of lumbar discs in symptomatic patients and making important contributions to both geometric modelling and biomechanical and ergonomic analyses.
