This study aims to evaluate the impact of pre-procedure training using a 3D simulator, based on lumbar CT images, on the success rate and efficiency of lumbar transforaminal steroid injections in patients who are expected to be difficult to treat. The training is provided to practitioners prior to performing the procedure on these patients.
This study aims to evaluate the impact of pre-procedure training using a 3D simulator, based on lumbar CT images, on the success rate and efficiency of lumbar transforaminal steroid injections in patients who are expected to be difficult to treat. The training is provided to practitioners prior to performing the procedure on these patients. The lumbar transforaminal epidural steroid injection (TFESI) is a widely used non-surgical treatment for chronic lower back pain and sciatica. TFESI is effective in reducing inflammation and alleviating pain, but the procedure can be challenging due to anatomical structures and individual variations. In particular, when chronic degenerative changes in the lower back, such as reduced disc height, hypertrophy of the facet joints, foraminal stenosis, lateral recess hypertrophy, and the formation of osteophytes, complicate the needle insertion path or increase the likelihood of the needle contacting bone, a high level of skill and experience is required. Recently, advancements in virtual reality (VR) technology have enabled highly realistic 3D simulations, which have spurred a growing body of research on VR-based simulations in healthcare. These simulations range from complex surgeries to disaster preparedness training in hospital settings. VR-based simulations offer an environment similar to real procedures, allowing practitioners to improve their skills and providing opportunities to rehearse complex or difficult cases in advance. However, despite the growing interest in VR simulations across various fields, research on their application to precise procedures like TFESI remains scarce. To the best of our knowledge, no studies have utilized real patient imaging to create 3D models in a virtual environment for this purpose. This study, against this background, aims to evaluate the impact of 3D virtual reality simulations using lumbar CT images of actual patients on the outcomes of transforaminal epidural steroid injections through a randomized controlled trial. The study will clarify how VR simulations can alleviate procedural difficulties and improve success rates and patient satisfaction compared to conventional image assessment methods. Moreover, it will contribute to establishing the foundation for incorporating VR-based simulations into standard protocols for complex procedures in the future.

Procedure time (seconds)
The time taken to perform each procedure will be measured in seconds.
Time frame: Immediately after the procedure
Number of fluoroscopic image shots
The number of fluoroscopic image shots taken will be measured.
Time frame: Immediately after the procedure
Number of bone contacts
The number of times the needle tip contacts the bone will be measured based on the practitioner's tactile feedback.
Time frame: Immediately after the procedure
Patient satisfaction
After the procedure, patient satisfaction will be assessed using a questionnaire consisting of four items, with responses measured on a 5-point Likert scale ranging from "strongly agree" to "strongly disagree."
Time frame: Immediately after the procedure
Presence of vascular injection
The procedure image will be analyzed to determine whether contrast dye was visualized in the blood vessels, confirming the presence or absence of intravascular injection.
Time frame: Immediately after the procedure
Procedure success or failure
The success or failure of the procedure, as determined by the practitioner, will be recorded.
Time frame: Immediately after the procedure
