This activity for healthcare professionals discusses cervical epidural injection, a minimally invasive procedure used to deliver corticosteroids or anesthetics into the epidural space of the cervical spine. This intervention is primarily indicated for managing neck pain, radiculopathy, and inflammation resulting from conditions such as herniated discs, spinal stenosis, or degenerative disc disease. The procedure involves precise needle placement, typically under fluoroscopic guidance, to ensure accurate medication delivery and avoid complications. Patient selection, proper technique, and thorough anatomical knowledge are critical for procedural success. When performed correctly, cervical epidural injections can reduce pain, improve function, and delay or eliminate the need for surgery. This educational activity improves clinician competence by reinforcing best practices in patient assessment, needle guidance, medication selection, and complication management. The course provides detailed instruction on imaging techniques and procedural protocols, enhancing safety and efficacy. The activity also emphasizes the importance of interprofessional collaboration involving clinicians, radiologic technologists, nurses, and pharmacists. Effective teamwork ensures accurate diagnosis, streamlined workflow, patient education, and optimal follow-up care. Such collaboration promotes individualized treatment plans, reduces procedural risks, and improves patient outcomes in cervical spine pain management. Objectives: Identify the appropriate clinical indications for cervical corticosteroid injections to support effective patient selection and targeted pain management. Assess the procedural technique for cervical corticosteroid injections to ensure accurate delivery, minimize risks, and optimize therapeutic outcomes. Screen patients for contraindications to cervical epidural injections, such as active infections, bleeding disorders, or severe spinal deformities, to ensure procedural safety. Coordinate post-procedural follow-up care with the interprofessional healthcare team, including pain reassessment, physical therapy referrals, and monitoring for adverse effects, to optimize long-term outcomes and reduce the need for surgical intervention.

Many individuals with cervical radiculopathy may experience symptom relief through cervical epidural injections, particularly when conservative treatments—such as rest, non-steroidal anti-inflammatory drugs (NSAIDs), physical therapy, and cervical collars—fail to provide adequate relief after 6 to 8 weeks. These injections are typically reserved for patients whose symptoms persist despite non-invasive therapies, provided there is no evidence of progressive neurological decline. Cervical radiculopathy affects approximately 107 per 100,000 men and 63 per 100,000 women annually, with peak incidence between ages 40 and 60.[1][2][3] While most cases resolve without invasive intervention, epidural injections can offer substantial relief in refractory cases, with about 50% of patients achieving a 50% reduction in pain lasting 3 months.[4][5][6] A standard treatment plan includes an initial injection followed by 1 or 2 additional injections spaced 2 to 4 weeks apart.[7] Common causes of radiculopathy include degenerative disc disease, spondylolisthesis, and cervical spinal stenosis, with nerve root compression being the most frequent source.[2][8] The transforaminal approach offers more precise targeting but carries higher risks, including infection, spinal headaches, nerve injury, and, rarely, paralysis or death.[9][10] In select cases, catheter-based techniques—utilizing a 20-gauge catheter advanced through a loss-of-resistance syringe—may provide access to higher cervical levels, particularly at the cervicothoracic junction.

Serious complications from epidural corticosteroid injections are uncommon, though fatal events have been reported, particularly with the transforaminal technique.[4][26][27] The overall complication rate associated with cervical epidural injections is estimated at approximately 16.8%.[28] These complications can occur if the needle becomes contaminated or inadvertently contacts the spinal cord, blood vessels, or spinal nerves.[18][29][30] Although the exact mechanisms are not fully understood, proposed causes include embolism and thrombus formation, aortic dissection leading to hemorrhage, arterial vasospasm, and dural puncture.[27][28][31][32] Potential adverse events include epidural hematoma, spinal abscess, hemorrhage, or infarction. Notably, no severe complications have been reported with the corticosteroid dexamethasone. Specific complications associated with interlaminar cervical epidural corticosteroid injections include dural puncture, vasovagal reactions, nerve root injury, epidural hematoma, subdural hematoma, transient paresthesias, transient blindness, epidural abscess, spinal cord injury, paralysis, and death. Transforaminal cervical epidural corticosteroid injections have been linked to transiently increased radicular pain, vasovagal reactions, dural puncture, temporary lightheadedness, transient global amnesia, paralysis, vertebral artery injury, cerebellar infarction, and death. The most frequently reported side effects were neck pain (6.7%), headache (1.7%), insomnia (1.7%), and vasovagal reactions (1.5%). The incidence of dural puncture with the transforaminal approach is approximately 0.3%, while the intralaminar approach shows a dural puncture rate between 0.25% and 2.0%.[33][34][35] Headaches have been reported in 4.5% of patients receiving interlaminar injections, and a temporary increase in radicular pain has been noted in up to 18% of cases.[36]

Cervical epidural injections are considered a minor outpatient procedure with a relatively low risk profile; however, serious complications have been reported and can lead to increased patient morbidity. Patients who have experienced stable radicular pain for at least 4 to 6 weeks due to cervical nerve compression may benefit from a cervical epidural corticosteroid injection. Before the procedure, a comprehensive patient evaluation and careful identification of potential risk factors are crucial. An interprofessional team approach enhances care for patients with cervical radiculopathy by reducing complications and improving outcomes and satisfaction. Patients should undergo the following assessments both before and after the injection: Evaluation by their primary care clinician. The patient should be considered for an epidural injection only after unsuccessful attempts at conservative management of cervical radiculopathy. Complete advanced imaging, including x-ray, computed tomography, or MRI, confirms the underlying pathology causing cervical radiculopathy by a radiologist. When imaging results are inconclusive, a neurologist or physical medicine specialist may conduct nerve conduction studies or electromyography to aid in diagnosis. Consult with a pharmacist regarding the use of blood thinners before the procedure. In cases of worsening or severe symptoms, a neurosurgeon should be consulted for surgical decompression of the spinal cord rather than a minimally invasive epidural injection. Various specialists may perform cervical epidural injections based on the severity and duration of the patient’s neck pain. Primary care clinicians can refer patients to specialists such as anesthesiologists, pain medicine physicians, physical medicine and rehabilitation clinicians, or interventional neurologists. Specially trained nurses in radiology, neuroscience, and rehabilitation are essential for the care of these patients. A fluoroscopy technician should be present for the procedure. Following the procedure, nurses should monitor the patient for post-procedure sequela.

Patients can typically return to full activity the day after a cervical epidural injection. While some may experience soreness at the injection site, this can usually be alleviated with ice and over-the-counter pain relievers like acetaminophen. The clinician or nursing staff typically reviews potential adverse events with the patient after the procedure. Opinions vary, but sometimes 3 doses are performed, up to 1 to 4 weeks apart, following an initial injection. Transient paralysis has been reported following injection; however, numbness or weakness of muscles usually resolves within 8 hours of onset. Occasionally, a patient may need to be monitored for more than 30 minutes after the epidural.

After the procedure, patients are typically monitored for 20 to 30 minutes. In some severe cases, or if sedation is given intravenously, intramuscularly, or orally, patients should be driven home, and it is recommended that someone stay with them that night. The corticosteroid's analgesic effects can relieve pain for a few weeks to a few months, making it easier for patients to engage in physical therapy. Physical therapy focuses on improving posture, mobility, and strength, addressing potential underlying causes or contributing factors to pain, and creating a personalized home exercise program to support long-term spinal health.
