Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Facet joints are synovial joints located on the dorsolateral side of the vertebral column. Normally, both facet joints are symmetrical. Facet tropism (FT) is defined as asymmetry between the angles of orientation of the joints, in which a facet joint in the same segment is more sagittally oriented than the other. In 1967, Farfan and Sullivan first reported that FT is a possible risk factor for the development of disk herniation. However, this is controversial as there are other views advocating that FT is not a risk factor for the development of cervical disc herniation. Further, it has been emphasized that patients with FT have a greater need for adjacent segment degeneration and new spinal surgery after spinal fusion surgeries than those without FT.

In the current literature, studies have been conducted to examine the clinical and radiological parameters that may be related to the effectiveness of cervical interlaminar epidural steroid injections (ILESI). The aim of this study was to examine the effect of the presence of FT on ILESI results in patients with cervical disc herniation-induced radicular pain.

With cervical facet tropism

Interlaminar Epidural Steroid Injection

Intervention Type PROCEDURE

The patient will be placed in the prone position and cutaneous anesthesia is performed with 3 mL of 2% prilocaine using the sterile technique. After imaging the C7-T1 space with fluoroscopy, it will be entered from the right/left paramedian part of the C7-T1 space with an 18G Touhy needle, and the C-arm will be set in the contralateral oblique position for depth determination.

Under intermittent fluoroscopic imaging, the needle will be advanced, and access to the epidural space wiil be confirmed by the loss of resistance technique. Afterwards, the epidural spread will be controlled with a contrast agent, and a mixture of 10 mg dexamethasone, 1 mL 2% lidocaine hydrochloride, and 1 mL 0.9% saline will be applied to the epidural space. The patient will be discharged with recommendations after being kept under observation for 2 hours post-procedure. All injections will be performed by the same pain medicine specialist who has at least 5 years of experience.
