Özet
AmAÇ: Yakın zamanda sakral kanal, omurga hastalıklarının minimal invaziv tanı ve tedavi işlemleri için "bir koridor olarak" sıkça kullanılmaya başlanmıştır. Çalışmanın amacı sakral kanalın, hiatusun ve çevre yapıların farklı yaş gurupları ve cinsiyete göre morfometrik analizlerinin çok kesitli bilgisayarlı tomografi yöntemiyle incelenmesidir. yÖNTem ve GeReÇLeR: Üç farklı yaş grubuna (20-80 yaş arasında) ayrılan 300 yetişkin (150 kadın ve 150 erkek; 20-80 yaş) hastanın multiplanar rekonstrüksiyon görüntüleri kaydedildi ve geriye dönük olarak incelendi. Sakral hiatus ve çevre yapılar ile sakral kanala ait çeşitli anatomik ölçümler yapıldı. Sakral kurvatür açısı ve lumbosakral lordotik açı kaydedildi. BuLGuLAR: Bazı olgularda hiatus yokluğu (%0,3), komplet agenezis (%1) ve kemik septum (%2,6) gibi kemik anomalilerine rastlandı. Anteroposterior (AP) Hiatus çapı olguların %5'sinde 2 mm nin altındaydı. Tüm yaş gruplarında, hiatus AP çapı ve hiatus alan ve "sakral kanal AP çapının en kısa mesafesinin" ortalaması, 60-80 yaş grubunda, 20-40 yaş grubuna göre daha kısaydı (p0,01). Sakral kanal AP çapın en küçük olduğu lokalizasyon, en çok olguların %59,2'unda S2 ve %33,9'unda S3 seviyesinde idi. Maksimum kurvatür seviyesi olguların %63,3'ün de S3 ve %26,7'sin de S2 seviyesinde idi. Sakral kürvatur açı ve lumbosakral lordotik açı sırayla 164 and 134 olarak ölçüldü. soNuÇ: Sakral yapılarda anatomik varyasyonlar sık görünür. Anatominin ayrıntılı analizi, girişimsel işlemlerin başarısını ve güvenilirliğini artırabilir.
AIm: The sacral canal has been frequently used as "a passage" for minimally invasive diagnostic and therapeutic procedures for spinal diseases. The aim of the present study was to investigate morphometric analyses of the sacral canal, hiatus, and surrounding structures according to different age groups and gender by using the "multidetector computed tomography" method. mATeRIAL and meTHods: Multiplanar-reconstructed images from 300 adult (150 females and 150 males, between 20 and 80 years old) were divided into three groups according to age and retrospectively examined. Various anatomic measurements of the sacral hiatus, surrounding structures, and sacral canal were performed. Sacral curvature angle and lumbosacral lordotic angle were noted. ResuLTs: Bony anatomic abnormalities such as absent hiatus (0.3%), complete agenesis (1%), and bony septum (2.6%) were detected in some cases. The anteroposterior (AP) diameter of the hiatus was less than 2 mm in 5% of cases. In all groups, the mean values of the hiatus AP diameter and area, and the shortest distance of the sacral canal AP diameter were shorter in the 60-80 years age group when compared with those in 20-39 years age group (p0.01). The shortest sacral canal AP diameter was commonly located at the S2 and S3 levels in 59.2% and 33.9% of cases, respectively. The levels of maximum curvature were at S3 and S2 in 63.3% and 26.7% of cases, respectively. Median sacral curvature angles and lumbosacral lordotic angles were measured as 164° and 134°, respectively. CoNCLusIoN: Sacral structures have morphometric variations. Understanding of the detailed anatomy may improve the reliability of interventional procedures.
