INTRODUCTION AND DEFINITION
A cervical disc herniation can compress a nerve root or sometimes the spinal cord; not every herniation requires an operation.
This page provides general patient information rather than an individual diagnosis. Decisions depend on symptoms, examination findings, relevant tests and patient preferences. Two people with the same diagnosis may require different care plans.
CAUSES AND SYMPTOMS
Symptoms may include neck-to-arm pain, numbness or weakness; loss of hand dexterity and poor balance can suggest spinal cord involvement.
The intensity of symptoms does not always match the extent of changes seen on scans. New significant weakness, walking difficulty or changes in bladder or bowel control require urgent medical assessment.
DIAGNOSIS AND ASSESSMENT
Neurological examination and cervical MRI, when indicated, identify compression and its relationship to symptoms.
Assessment begins with the clinical history and an appropriate examination of strength, sensation and reflexes. X-rays, MRI, CT or nerve studies are used when they can answer a specific clinical question. A scan report alone does not establish the need for surgery.
TREATMENT OPTIONS
Nonoperative care may help selected nerve-root symptoms, while suspected myelopathy requires separate specialist assessment.
Management depends on the underlying cause, severity, overall health and realistic goals of treatment. Depending on the condition, monitoring, nonoperative care, activity modification, rehabilitation or clinician-selected medication may be considered. No single treatment suits everyone.
SURGICAL PROCESS WHEN INDICATED
Depending on the findings, surgery may involve anterior discectomy and fusion, disc replacement in selected patients, or posterior decompression.
Before surgery, the team should discuss likely benefits, alternatives and individual risks. Depending on the operation, complications may include bleeding, infection, anesthesia problems, nerve or spinal cord injury, and persistent symptoms; no outcome can be guaranteed.
RECOVERY AND POSTOPERATIVE PERIOD
Arm pain can improve early, while numbness and weakness may take longer; collar use and movement restrictions depend on the operation.
Follow-up, movement restrictions and return to work or sport vary with the procedure and neurological findings. New or worsening weakness, fever, wound drainage or bladder and bowel changes require prompt medical review.
