Lumbosakral vertebral kolonun sagittal morfolojisi ile lumbal intervertebral disk dejenerasyonunun derecesi arasındaki ilişki

Amaç: Bu çal›flmada genifl genç eriflkin örnekleme grubunda lumbosakral morfoloji ile interver- tebral disk dejenerasyonunun derecesi aras›ndaki iliflki araflt›r›ld›. Ek olarak farkl› morfolojik pa- rametreler (sakral yüzey aç›s› ve sakral kifoz aç›s›) ile lumbal disk herniasyonu ya da disk deje- nerasyonunun varl›¤› aras›ndaki ba¤lant› de¤erlendirildi. Çal›flma plan›: 2008-2009 y›llar› aras›nda alt bel a¤r›s› nedeni ile klini¤imize baflvuran hastala- r›n lumbal manyetik rezonans görüntüleme (MRG) tetkikleri retrospektif olarak de¤erlendirildi. Daha önce lumbal spinal cerrahi geçirmifl hastalar ya da lomber MRG tetkikinde ciddi konjeni- tal anomali, inkomplet ya da komplet lumbosakral transizyon, ciddi skolyoz ve spondilolizis ya da spondilolistezis tespit edilen hastalar çal›flma kapsam›na al›nmad›. Geri kalan hastalardan yafl- lar› 20-30 aras›nda olan 131 kad›n hasta çal›flma kapsam›na dahil edildi. Her hasta için interver- tebral disk herniasyonu ve dejenerasyonunun varl›¤› incelendi ve disk dejenerasyonunun derece- si de¤erlendirildi. Ayr›ca her hasta için lomber lordoz, sakral yüzey ve sakral kifoz aç›s› ölçül- dü. Sonuçlar: Sakral kifoz ve lomber lordoz aç›s› azald›kça ya da sakral yüzey aç›s› artt›kça interver- tebral disk dejenerasyonun düzeyinin artt›¤› görüldü. Lomber lordoz, sakral kifoz ve sakral yüzey aç›s›, intervertebral disk dejenerasyonu bulunan (s›ras›yla 23.37±7.09°, 163.09±9.48°, 104.34± 5.47°) ve bulunmayan (s›ras›yla 26.94±7.39°, 168.94±10.52°, 100.83±4.32°) bireyler aras›nda an- laml› olarak farkl›l›k (s›ras›yla p=0.006, p=0.001, p=0.0001) gösterdi. Ayr›ca lomber lordoz, sak- ral kifoz ve sakral yüzey aç›s› intervertebral disk herniasyonu bulunan (s›ras›yla 22.82±6.94°, 162.23±9.53°, 104.94±5.19°) ve bulunmayan (s›ras›yla 27.25±7.26°, 169.39±9.96°, 100.48±4.33°) bireyler aras›nda anlaml› olarak (s›ras›yla p=0.001, p=0.0001, p=0.0001) farkl›yd›. Ç›kar›mlar: Sakral kifoz ve lomber lordoz aç›s› azald›kça ya da sakral yüzey aç›s› artt›kça in- tervertebral disk dejenerasyonun düzeyi artar, ayr›ca intervertebral diskte dejenerasyon ve herni- asyon geliflim riskinde art›fl izlenir.
