MEASUREMENT OF LUMBAR INTERVERTEBRAL DISC HEIGHTS BY COMPUTED TOMOGRAPHY: MORPHOMETRIC STUDY

Amaç: Çalışmanın amacı sağlıklı insan lomber vertebral disk aralıklarının bilgisayarlı tomografi ile ölçümünü yapmaktır.Materyal ve metod: Acil servise minör travmalar nedeni ile başvuran ve hikayelerinde lomber bölgeden hastalık veya operasyon bulunmayan 18 ve 60 yaş arası 50 bayan ve 50 erkek hasta retrospektif olarak incelendi.Sonuçlar: Çalışmada 50 bayan (% 50) ve 50 erkek (% 50) toplam 100 hasta incelendi. Ortalama yaş erkeklerde 44.84 ± 9.9 ve bayanlarda 45.1 ± 10.7 olarak hesaplandı. Cinsiyetler arasında yaş bakımından istatistiksel anlamlı fark yoktu(p=0.950). Erkeklerde L1-2 mesafesi disk aralığı yüksekliği ortalama 9.46 ± 0.86 mm, bayanlarda 9.81 ± 0.95 mm olarak bulundu ve bayanlarda bu aralık istatistiksel anlamlı olarak daha büyük hesaplandı(p=0.006). L2-3 disk aralığı erkeklerde ortalama 9.68 ± 0.9 mm, bayanlarda 9.42 ± 0.68 mm olarak hesaplanmış ve istatistiksel fark bulunamamıştır. L3-4, L4-5 ve L5-S1 disk mesafeleri erkeklerde bayanlarla karşılaştırıldığında daha yüksek olarak bulunmuştur.Çıkarım: Bu çalışmada lomber disk aralıkları yükseklikleri morfometrik olarak bilgisayarlı tomografi ile hesaplanmaya çalışılmış ve disk aralıklarına yapılan ameliyatların daha güvenli yapılabilmesi için anatomik bilgi desteği sağlanmaya çalışılmıştır.

LOMBER DİSK ARALIKLARIN YÜKSEKLİKLERİNİN BİLGİSAYARLI TOMOGRAFİ İLE ÖLÇÜMÜ: MORFOMETRİK ÇALIŞMA

Purpose: We aimed to obtain data from computed tomography of healthy human lumbar intervertebral disc heights.Materials and Method: We inspected 50 female and 50 male between the ages of 18 and 60 who have admitted to emergency room for minor traumas. Data collected from files of the patients who did not have any history of operations or disease for the lumbar spine rethrospectively.Results: This study included a total of 100 patients, of whom 50 were female (50 %) and 50 were male (50 %). Mean age was 44.84 ± 9.9 years for males, and 45.1 ± 10.7 for females. There was no statistically significant difference between males and females of age (p=0.950). Intervertebral disc heights between L1 and L2 vertebrae were 9.46 ± 0.86 mm in males, and 9.81 ± 0.95 mm in females. The L1-L2 intervertebral disc heights were were significantly higher in females (p=0.006). The L2-L3 intervertebral disc heights were 9.68 ± 0.9 mm, and 9.42 ± 0.68 mm in males and females, respectively, which were statistically similar (p=0.072). L3-L4, L4-L5, and L5-S1 intervertebral disc heights were significantly higher in males, when compared to females. Conclusions: This study has been conducted to evaluate lumbar disc heights with morphometric measurements by using computed tomography to support anatomic knowledge for safe surgery performed to intervertebral disc space.
