Sacrum is formed by the fusion of five sacral vertebrae and forms the lower part of vertebral column. The opening present at the lower end of sacral canal is known as sacral hiatus. Anatomical variations in morphology and morphometry of sacral hiatus are important clinically as well as surgically. 159 dry clean human Sacra were taken from Department of Anatomy, Sri Guru Ram Das Institute of Med...

Sacral nerve stimulation through the retrograde approach has been used for peroneal or irritable bowel syndrome through the retrograde approach. However, several reasons, lead could not be advanced down ward. In this case, anterograde sacral nerve stimulation through the sacral hiatus could be used. The aim of this report is to present of technique of sacral nerve root stimulation through the s...

The variations of sacral hiatus in dry bone are important as it determines access of sacral hiatus for caudal epidural anesthesia and analgesia. So the present study was conducted on 44 adult dry sacra in department of Anatomy, All India Institute of Medical Sciences,Bhubaneshwar,Odisha,India with the aim to find out the anatomical variations of sacral hiatus(SH) including shape, length, antero...

AIMS To test different technical setups for stimulation and recording of the sacral reflex, provide confidence intervals and discuss the utility of the sensory threshold and the sacral reflex threshold in women with "non-neurogenic" sacral dysfunction. METHODS All women without neurologic disorder, with normal neurologic examination, and bilaterally normal quantitative electromyography of the...

BACKGROUND Upper sacral segment dysplasia increases the risk of cortical perforation during iliosacral screw insertion. Dysmorphic sacra have narrow and angled upper osseous corridors. However, there is no validated definition of this anatomic variation. We hypothesized that pelves could be quantitatively grouped by anatomic measurements. METHODS One hundred and four computed tomography (CT) ...

The laminae of fifth and sometimes fourth sacral vertebrae fail to fuse posteriorly in the sagittal plane leading to formation of a deficiency in the posterior wall of the sacral canal commonly known as sacral hiatus. During osteology demonstration class of MBBS students of the Department of Anatomy, U.C.M.S and G.T.B Hospital, Delhi, we noticed a sacrum in which sacral hiatus was extending to ...

Background: Sacral pit is a shallow or deep dimple in the lower sacral region, with a reported prevalence of 3-5% among newborns. The aim of the present study was to investigate spinal cord abnormalities in newborns with sacral pit via ultrasound examinations. Methods: In this descriptive study, 3071 infants born at 34-42 weeks of gestation were studied in hospitals affiliated to Islamic Azad U...

BACKGROUND Caudal block is a common technique in children for reducing postoperative pain, and there have been several reports on the variations of the sacral canal in children. However, previous studies have mainly focused on the needle trajectory for caudal block, and there is limited information on the structural variations of the sacrum in children. The purpose of this study was to analyze ...

OBJECTIVE To assess the outcomes and safety after CT-guided percutaneous sacroplasty in patients with painful sacral insufficiency fractures or pathologic sacral lesions. METHODS A retrospective multicenter analysis of consecutive patients undergoing CT-guided sacroplasty for painful sacral insufficiency fractures or sacral lesions was undertaken. The inclusion criteria consisted of severe sa...

Introduction: Single bony landmark may not help to detect the hiatus properly for caudal epidural block (CEB). The aim of the study was to measure the different aspects of the sacral hiatus and to identify significant anatomical landmarks to locate it. Methods: Different morphometric measurements were taken of one hundred sacra with a Vernier caliper. These measurements may provide a guideline ...
