Full description
After the approval of the institutional review board and the Ethics Committee of Al Fayoum University number (D228) , and written informed consent from all patientṣ Pilot study will be done to confirm this sample size .The patients are classified in two groups group P for cervical epidural and group F for facet injection. Patients Inclusion criteria of chronic cervical pain syndromes will be made from their history, symptoms, and imaging diagnosis. Patients will be lying down on the prone position. In group( F) Under the C-arm fluoroscopic guidance targeted zygapophyseal joints will be identified. The mixture of 2 mL of 2% lidocaine with 2 ml of beta methasone (6 mg/ml) will be injected in the joints unilaterally or bilaterally according to complaints of patients. Another group ( P) patients will undergo translaminar or interspinous cervical epidural block (CEBs). The translaminar or interlaminar approach is considered the safest and most effective technique for cervical epidural placement.The patient will be in a prone position. This procedure will be performed with fluoroscopic guidance. The patient will be placed in an optimal flexed cervical spine posture stabilized with enough resistance to prevent movement of the head during the procedure. The skin will be prepared with an antiseptic solution. The midline of the selected interspace will be identified under fluroscopic guidance. LA, such as lidocaine, will be used, to mark the intended site of skin entry. As much as 1 mL of lidocaine will be used to infiltrate the skin and subcutaneous tissues. We will insert a 25-gauge, 2-inch needle exactly into the targeted midline. After the LA has been given time to anesthetize the area,we will hold the needle firmly at the hub with the left thumb and index finger. Then the palm of the left hand will be placed firmly against the patient's neck, so that the left hand acts as a unit to stabilize, protect, and control the needle's trajectory and its metered ingress from any unexpected patient activity. The needle will be then advanced with the left hand, which is braced against the neck with the needle hub held tightly between the left thumb and forefinger. We will use the right hand to monitor resistance through a syringe containing air. With constant pressure applied to the plunger of the syringe through light pressure applied by the right thumb, the needle and syringe will be advanced in a slow and deliberate manner. As the bevel passes through the ligament flavum and enters the epidural space, a sudden loss of resistance that we will appreciate also we can appreciate the entrence the epidural space under fluroscopic guidance in condition that not to cross J line (a line appear under flouroscopy imaging facet joint articulation if crossing this line we will puncture the dura).
Needle position within the epidural space will be checked by using fluoroscopic verification and by repeating the loss of resistance maneuver. The cervical epidural space should accept 0.5-1 mL of air or sterile preservative free saline without significant resistance. The force required to depress the plunger should not exceed that which is necessary to overcome the resistance of the needle. Any significant pain or sudden increase in resistance during the injection suggests incorrect needle placement, so the injection will be stopped and we will assess the position of the needle using fluoroscopy. If the needle remains satisfactorily placed and loss of resistance within the epidural space is confirmed without additional patient report of pain, gentle aspiration will be checked to assure that the needle is not positioned in the subarachnoid space or that it's not intravascular. If cerebrospinal fluid (CSF) is aspirated, we will repeat the block attempt at a different interspace. If aspiration of blood occurs, the needle will be tightly rotated and the aspiration test will be repeated. If the aspiration of blood continues, the procedure will be aborted due to the danger of developing an epidural hematoma and possibly neurological compromise. when the needle is correctly placed in the midline of the epidural space, then injection of the mixture of 2 mL of 2% lidocaine with 2 ml of beta methasone (6 mg/ml) will be done .
