Cervical epidural steroid injections (CESIs)~For the conservative management of head, neck, and upper extremity pain~Important to identify the epidural space for minimizing the chance of a dural puncture injection~Dural puncture injection makes CESIs prone to rare but catastrophic complication like permanent spinal cord injury~The hanging drop (HD) technique~Commonly used for identifying the cervical epidural space~Using the negative pressure in the epidural space~The subject of debate whether the epidural space exhibits negative pressure~In previous studies using a closed pressure measurement systems~The epidural pressure (EP) was commonly positive at the thoracic level in the lateral decubitus position.~EP was consistently negative only in the sitting position.~EP might be influenced by body position.~The patient should be sitting for using the HD technique.~No report or peer-reviewed literature to demonstrate the cervical epidural pressure (CEP) now.~The hypothesis of this study~There is a difference in the cervical epidural pressure between in the prone and sitting positions~To evaluate this hypothesis, CEPs in the prone and sitting groups were measured and compared in the two groups.~Using a closed pressure measurement system~Under fluoroscopic guidance.
