Cervical Disc Herniation
What is a cervical disc herniation?
Between each vertebra in the cervical spine sits an intervertebral disc — a structure with a tough outer fibrous ring (the annulus fibrosus) and a soft gel-like centre (the nucleus pulposus). A cervical disc herniation occurs when the nucleus pulposus pushes through a tear in the annulus fibrosus, potentially compressing adjacent nerve roots or, in severe cases, the spinal cord itself.
The terminology around disc injuries can be confusing — herniation, prolapse, bulge and slipped disc are often used interchangeably by patients, though they describe slightly different degrees of disc disruption. A disc bulge involves the outer ring bulging outward without a discrete tear. A herniation involves nuclear material extruding through the annular fibres. A protrusion is a contained herniation. An extrusion involves disc material that has broken free of the disc space. In clinical practice the most important distinction is whether nerve compression is producing symptoms, and how severe those symptoms are.
What causes a cervical disc herniation?
Most cervical disc herniations develop from a combination of age-related disc degeneration and mechanical loading rather than a single dramatic event. As discs degenerate they lose hydration and height, the annular fibres become more vulnerable to tearing, and relatively minor forces can produce herniation in a disc that is already compromised. The incidence of cervical disc herniation is more common in people in their third to fifth decades of life and is more common in women, accounting for more than 60% of cases.
Acute disc herniations can also occur from significant trauma — motor vehicle accidents, contact sport injuries, or heavy lifting — particularly at the C5-6 and C6-7 levels, which are the most commonly affected segments in the lower cervical spine.
Lifestyle factors that accelerate disc degeneration include prolonged poor posture — particularly sustained forward head posture at a desk or on a phone — smoking, sedentary behaviour, and occupations involving heavy manual work or prolonged vibration.
What are the symptoms?
Symptoms depend on whether the herniation is compressing a nerve root, the spinal cord, or neither.
When a nerve root is compressed — cervical radiculopathy — symptoms include neck pain that radiates into the shoulder, arm, forearm and hand in a pattern corresponding to the affected nerve root. Tingling, numbness and weakness in the arm or hand are characteristic. The specific distribution of symptoms provides important diagnostic information about which disc level is involved — C6 radiculopathy affects the thumb and index finger, C7 the middle finger, C8 the ring and little fingers.
When the herniation is large enough to compress the spinal cord — cervical myelopathy — the symptoms are more serious and include bilateral arm or leg symptoms, hand clumsiness, gait disturbance and bladder dysfunction. Myelopathic symptoms require prompt specialist medical assessment.
Many cervical disc herniations produce only local neck pain and stiffness without nerve compression, particularly in the early stages. Headaches, upper trapezius tightness and reduced neck movement are common accompanying features.
How is it diagnosed?
Clinical assessment by a physiotherapist includes evaluation of neck movement, neurological testing of the upper limb — including reflexes, sensation and muscle strength in the relevant distributions — and specific tests such as the Spurling's test (axial compression with lateral flexion toward the affected side that reproduces arm symptoms) and the shoulder abduction relief sign. These tests help confirm or raise suspicion of radiculopathy before imaging is organised.
MRI is the gold standard imaging for cervical disc herniation, showing the disc material, its relationship to the nerve roots and cord, and the condition of the surrounding structures. It is worth noting — as with many spinal conditions — that imaging findings need to be interpreted carefully. Disc herniations are common incidental findings on MRI in people without symptoms, and the severity of imaging changes does not reliably predict symptom severity or prognosis.
Does a cervical disc herniation need surgery?
The majority of cervical disc herniations — including those producing radiculopathy — resolve or improve significantly without surgery. The natural history of cervical disc herniation is favourable in most cases: the herniated material gradually resorbs, nerve root compression reduces, and symptoms improve over weeks to months. Surgery is generally considered when neurological deficit is progressive, when symptoms are severe and not responding to conservative management, or in the rare case of myelopathy with significant cord compression.
How can physiotherapy help?
Physiotherapy is the cornerstone of conservative management for cervical disc herniation and is highly effective for the majority of presentations. The goal is to manage pain, optimise conditions for natural disc resorption, and restore full function.
In the acute phase, pain management through positioning advice, activity modification, and gentle range-of-motion exercises within comfortable limits is the priority. Neural mobilisation techniques — gentle nerve gliding movements that reduce neural mechanosensitivity — can significantly reduce arm symptoms when radiculopathy is present. Cervical traction, either manual or mechanical, can provide temporary symptom relief by reducing compression on the affected nerve root.
As the acute phase settles, deep cervical flexor retraining is central — these muscles are consistently inhibited in people with neck pain and disc pathology, and their rehabilitation significantly reduces pain and protects the cervical spine from further injury. Real time ultrasound guides this retraining by providing direct visualisation of the deep muscles that are impossible to feel and difficult to isolate without biofeedback.
Scapular and thoracic spine rehabilitation addresses postural contributors to cervical loading. Clinical Pilates provides an excellent environment for this work — improving thoracic mobility, scapular control and deep cervical stability in a way that directly reduces mechanical stress on the herniated disc segments.
Dry needling of the cervical and periscapular musculature assists with pain management and muscle relaxation, particularly during acute flare-ups.
For patients whose disc herniation occurred in a motor vehicle accident or workplace injury, CTP and WorkCover funded physiotherapy is available.
