Cervical Disc Herniation: A Stroke Risk?

A herniated cervical disc, commonly known as a slipped disc, can cause a variety of symptoms, including pain, numbness, and weakness in the neck, shoulders, arms, and hands. This occurs when the central part of the intervertebral disc protrudes into the spinal canal, often due to a tear in the fibrous ring surrounding the soft inner core. While these symptoms can sometimes be mistaken for a stroke, it is important to distinguish between the two conditions as they have different underlying causes and may require different treatments. This paragraph will explore the potential link between a herniated cervical disc and stroke-like symptoms, as well as the implications for diagnosis and management.

Herniated discs can cause pain in the neck, shoulders, and arms

A herniated disc, also known as a slipped disc, occurs when the central part of the intervertebral disc protrudes into the spinal canal. This can cause pain in the neck, shoulders, and arms, known as radiculopathy. The pain may radiate down the arm and into the hand, depending on the location of the herniation.

The cervical spine, or neck, is made up of seven vertebrae, C1 to C7, which are separated by discs. These discs act as shock absorbers, preventing the vertebrae from rubbing together. However, when a disc herniates, the gel-like centre of the disc ruptures through a weak area in the tough outer wall. This can irritate the spinal nerves, causing inflammation and swelling, which results in pain.

The location of the pain can indicate the presence of a herniated cervical disc. Arm and shoulder pain is a telltale sign, as is a shooting pain in the shoulder blade when turning the neck to the side. Muscle spasms, frequent headaches, and weakness are also possible indicators.

To diagnose a herniated cervical disc, a physician will take a complete medical history and perform a physical exam. Imaging studies such as Magnetic Resonance Imaging (MRI) scans, myelography, Computed Tomography (CT) scans, and X-rays can also be used to confirm the diagnosis.

Treatment for a herniated cervical disc typically begins with conservative, non-surgical methods such as rest, pain medication, spinal injections, and physical therapy. Most people will recover within six weeks using these methods. However, if symptoms persist, surgery may be recommended.

The condition can lead to myelopathy, causing issues with walking, spasticity, and bowel-bladder incontinence

A herniated cervical disc, commonly known as a slipped disc, is a condition in which the central part of the intervertebral disc protrudes into the spinal canal. This protrusion can impinge on the nerve, causing pain, numbness, and weakness in the skin and muscle supplied by the affected nerve. In some cases, a cervical disc may compress the spinal cord, leading to a condition called myelopathy.

Myelopathy is characterised by issues with walking, spasticity, and bowel-bladder incontinence. Patients with cervical myelopathy often experience balance and coordination problems, making walking difficult. They may also develop manual dexterity issues, such as having trouble buttoning shirts. In more severe cases, they can experience bowel and bladder dysfunction, also known as incontinence.

The symptoms of cervical myelopathy can vary depending on the location and extent of spinal cord compression. It usually affects the upper extremities, causing numbness, tingling, or weakness in the arms and hands. In some cases, it may also affect the legs.

The condition typically progresses over time and can lead to more severe complications if left untreated. Surgical and non-surgical treatments are available, with surgery being necessary if there are signs of myelopathy or if conservative treatments fail.

Herniated discs are caused by ageing or trauma, and can occur in the neck

A herniated disc, also known as a slipped disc, occurs when the soft, jelly-like centre of a spinal disc pushes through a crack in the outer layer. This can cause inflammation and compression of the nearby nerves, resulting in back pain, numbness, and tingling. While herniated discs are most common in the lower back, they can also occur in the neck.

Herniated discs are typically caused by two factors: ageing and trauma. Ageing discs naturally degenerate, becoming less flexible and more prone to damage. This degeneration is caused by years of wear and tear, use and misuse. As with other body tissue, discs dry out and become more brittle as a person ages, making them more susceptible to damage. The outer layer of the disc starts to display fissures and tears, usually in a person's 20s or 30s, even if these don't yet cause problems. The precise features of disc ageing vary widely between individuals, so there is no predictable pattern to disc degeneration.

Trauma can also cause disc herniation. Certain conditions or behaviours could increase the risk of a herniated disc, including demanding jobs with repetitive bending, lifting, or pulling, carrying extra weight (especially in the abdomen), and smoking. Smoking may interfere with the oxygen supply to the discs, and extra weight adds more force to the spine.

The symptoms of a herniated disc in the neck include pain in the neck, shoulders, and arms. This is called radiculopathy. Pain may radiate down the arm into the hand in the specific distribution of the compressed nerve root. If a cervical disc compresses the spinal cord, there may be significant problems with walking, spasticity, and bowel-bladder incontinence. This is called myelopathy.

Symptoms of a herniated disc include neck pain, radicular pain, and cervical radiculopathy

A herniated disc in the cervical spine can cause neck pain, radicular pain, and cervical radiculopathy.

Neck Pain

Neck pain is a prevalent issue that can cause significant pain and disability. It is responsible for up to 40% of work absenteeism.

Radicular Pain

Radicular pain is a type of pain that radiates along the path of a spinal nerve root. It can be caused by compression or irritation of a spinal nerve root. In the case of a herniated cervical disc, the disc can impinge on the nerve root, causing inflammation and pain.

Cervical Radiculopathy

Cervical radiculopathy occurs when a nerve root in the spine is compressed or impeded, leading to pain that spreads beyond the neck to other areas such as the arm, chest, shoulders, and upper back. It can also cause muscle weakness and impaired deep tendon reflexes.

The treatment for these symptoms will depend on their severity and can range from conservative management, including medication and physical therapy, to interventional therapies such as epidural steroid injections or surgical decompression.

Treatment options include medication, physical therapy, and in some cases, surgery

Treatment options for a herniated cervical disc include medication, physical therapy, and in some cases, surgery.

Medication

Nonsteroidal anti-inflammatory drugs (NSAIDs) are typically the first type of medication recommended to reduce inflammation and relieve pain. Examples of over-the-counter NSAIDs include Advil, Aleve, Motrin, aspirin, naproxen (Alleve, Naprosyn), ibuprofen (Motrin, Nuprin, Advil), and celecoxib (Celebrex). If over-the-counter medications do not provide sufficient pain relief, doctors may prescribe stronger NSAIDs, muscle relaxants, or oral steroids. Due to the risk of side effects, prescription painkillers are usually only used for a short time, such as during severe flare-ups or for one to two weeks.

Physical Therapy

Physical therapy can help improve the neck's strength, flexibility, and posture. Therapists may employ traction, ultrasound, electrical muscle stimulation, and exercises such as chin tucks to relax the muscles and reduce inflammation from the compressed spinal nerve. Therapeutic injections, such as cervical epidural steroid injections, may also be considered to reduce inflammation and provide pain relief.

Surgery

If non-surgical treatments are ineffective or if there are signs of myelopathy or radiculopathy, surgery may be necessary. The most common operation for a herniated cervical disc is anterior cervical discectomy and fusion (ACDF). This procedure involves making an incision in the neck to expose the spine, removing the disc, and inserting a bone graft or cage to create fusion. A posterior cervical discectomy may also be performed, where the bone is removed from the back of the spine to expose and remove the compressed nerve root. In recent years, artificial discs have been introduced as a treatment option, allowing for the preservation of normal neck mobility.
