Objectives The aim of this study was to clarify differences in the anatomic structure sacral hiatus and angle needle insertion during caudal epidural steroid injection using ultrasound guidance patients according sex age. Methods A total 237 with low back pain or without sciatica were included. Sonograms obtained, performed all patients. intercornual distance, diameter canal, thickness sacrococcygeal ligament, optimal for insertion, actual measured. Results Between men women, significant observed distance (17.7 versus 16.5 mm; P < .01) ligament (4.3 3.9 = .02). In patients, ( r 0.28) canal 0.40) positively correlated .01). −0.24), −0.27), −0.29), −0.18) negatively men, only age −0.30). Conclusions We found that has between different sexes ages. Understanding these differences, especially may improve safety reliability injection.
