Anatomical variations of sacral hiatus and associated clinical relevance - A review
نویسنده
چکیده
Sacral hiatus is caudal opening of sacral canal. Caudal epidural anaesthesia for various therapeutic and diagnostic procedures is administered through sacral hiatus. 25% failure rate of caudal epidural block has been reported in literature. The failure rate of this procedure may be due to variant anatomical features of sacral hiatus. Hence knowing the anatomical variations in shape, size, level of apex and baseof sacral hiatusis of paramount importance to clinicians to reduce failure rate of caudal epidural block. For this review, literature search was done in the department of anatomy using databases, Scielo, Scopmed, medline, pubmed and Wiley online library. Only English language articles and standard text books were referred. The anatomical features of sacral hiatus has immense value to orthopaedic surgeons, obstretricians, paediatricians, anaesthecians and anatomists. This review will update and consolidate the information on sacral hiatus and will serve a ready reference for future researchers and clinicians.

BACKGROUND This study determined the landmarks for caudal epidural block (CEB) after morphometric measurements of the sacral hiatus on dry sacral bones. Anatomical features of the sacral hiatus of clinical importance during CEB, along with distances and angles of use in detecting the apex, were measured. This provides detailed knowledge of the anatomy of the sacral hiatus and practical landmark...
متن کاملAnatomical Profile and Morphometric Evaluation of Human Sacral Hiatus in North Indians
Successful caudal epidural block (CEB) for various gynaecological and orthopaedic procedures requires an elaborate knowledge of anatomical profile of sacral hiatus. Varied morphology of sacral hiatus is likely to influence the success rate of CEB. Scanty literature is available on the morphometry of sacral hiatus in North Indian subjects. Therefore, sacral hiatus of 60 North Indian human sacra ...
