CERVICAL RETROLISTHESIS

Causes of Cervical Retrolisthesis:

Cervical retrolisthesis is a multifactorial condition, and several underlying factors can contribute to the development of this spinal deformity. The most common causes include:

Degenerative Changes (Aging Process)

• Over time, the intervertebral discs and surrounding ligaments in the cervical spine undergo degenerative changes. The discs lose water content and elasticity, leading to a reduction in disc height and the weakening of the ligaments. This degeneration causes vertebrae to shift from their original positions, potentially leading to retrolisthesis.
• Osteoarthritis, a common degenerative joint disease, can also contribute to the breakdown of cartilage and the formation of bone spurs (osteophytes). These bony projections may force vertebrae backward, resulting in cervical retrolisthesis.

Trauma or Injury

• A sudden trauma, such as whiplash from a car accident, a sports injury, or a fall, can cause cervical retrolisthesis. The impact can damage the soft tissues, muscles, and ligaments that support the spine, leading to misalignment or backward displacement of vertebrae.
• Repetitive microtrauma or stress to the cervical spine, such as from poor posture, heavy lifting, or sustained forward head positioning, can gradually weaken the supportive structures and cause vertebral misalignment.

Congenital Spine Anomalies

• Some individuals are born with spinal abnormalities that predispose them to conditions like retrolisthesis. These congenital anomalies can result in vertebral malformation, improper vertebral alignment, or weakened spinal support, leading to a higher risk of displacement over time.

Disc Pathology

• The intervertebral discs act as cushions between the vertebrae, maintaining proper spacing and alignment. Disc herniation, bulging discs, or disc degeneration can disrupt this spacing, increasing the risk of retrolisthesis. When the disc loses its structural integrity, the vertebrae are more prone to shifting out of place.

Muscle Weakness or Imbalance

• Weak or imbalanced cervical muscles can lead to insufficient support for the vertebrae. Conditions like kyphosis or scoliosis may increase the stress on the spine, making it more susceptible to displacement and abnormal curvature, which may cause cervical retrolisthesis.

Systemic Diseases

• Systemic conditions like osteoporosis and rheumatoid arthritis can also contribute to cervical retrolisthesis. Osteoporosis leads to weakened vertebrae, making them more prone to movement and displacement, while rheumatoid arthritis causes joint inflammation that can affect spinal stability.

Cervical Retrolisthesis Symptoms:

Cervical retrolisthesis can present with a wide range of symptoms depending on the severity of the displacement and the extent of nerve or spinal cord involvement. The symptoms can appear in the neck or radiate to other parts of the body due to nerve compression. Common symptoms include:

Neck Pain and Stiffness

• One of the most common symptoms of cervical retrolisthesis is persistent neck pain. This pain can range from a dull ache to sharp, stabbing pain. Stiffness in the neck often accompanies this pain, limiting the range of motion and making it difficult to turn the head or look up and down.

Radiating Pain (Radiculopathy)

• If the displaced vertebra compresses nearby nerves, it can cause radiating pain down the shoulders, arms, and even into the hands and fingers. This condition, known as cervical radiculopathy, may result in shooting pain, numbness, tingling, or burning sensations along the affected nerve pathway.

Headaches

• Cervical retrolisthesis can lead to tension-type headaches or cervicogenic headaches, which originate from the neck and radiate toward the head. These headaches are often caused by muscle tension, nerve irritation, or changes in spinal alignment due to vertebral displacement.

Muscle Weakness and Fatigue

• Compression of spinal nerves can cause weakness in the muscles of the upper extremities, leading to reduced grip strength, arm fatigue, and difficulty performing everyday tasks like lifting objects or typing.

Balance and Coordination Issues

• In severe cases, cervical retrolisthesis may compress the spinal cord, leading to balance problems, difficulty walking, or impaired coordination. This is a more serious symptom and may indicate that the spinal cord is being compromised.

Numbness and Tingling

• Numbness and tingling in the upper extremities, particularly the arms and fingers, can appear from nerve root compression caused by the misaligned vertebrae. This sensory loss may occur with a “pins and needles” sensation.

Diagnosis Methods:

Accurate diagnosis of cervical retrolisthesis is essential for developing an effective treatment plan. The diagnostic process involves a combination of patient history, physical examination, and imaging studies.

Patient History

• A detailed medical history is crucial to understand the patient’s symptoms, their onset, and any potential causes, such as trauma or degenerative conditions. The clinician will inquire about the patient’s level of pain, location, and any history of injuries or underlying conditions like arthritis.

Physical Examination

• A physical examination will focus on evaluating the range of motion in the neck, muscle strength in the upper extremities, and reflexes. The clinician may also check for signs of nerve compression, such as numbness, tingling, or muscle weakness.
• Special tests, like the Spurling test, may reproduce symptoms of cervical radiculopathy, helping to confirm the involvement of nerve roots.

Imaging Studies

Imaging is a key component of diagnosing cervical retrolisthesis. Common imaging modalities include:

• X-rays: X-rays are typically the first imaging test ordered to assess the alignment of the cervical vertebrae. Lateral (side-view) X-rays can reveal the degree of vertebral displacement, as well as the presence of bone spurs or disc degeneration.
• MRI (Magnetic Resonance Imaging): An MRI provides a more detailed view of the soft tissues, including the intervertebral discs, spinal cord, and nerve roots. It helps identify nerve compression, herniated discs, or any damage to the spinal cord caused by retrolisthesis.
• CT Scan (Computed Tomography): CT scans are useful for providing detailed images of the bony structures in the spine. Doctors may use this imaging modality if there is a need to assess fractures, bone spurs, or severe degenerative changes.
• Flexion and Extension X-rays: These specialized X-rays are taken while the patient moves their neck through flexion (bending forward) and extension (bending backward). These images help assess the stability of the cervical spine and the extent of vertebral displacement during movement.

Electromyography (EMG) and Nerve Conduction Studies

• If nerve involvement is suspected, doctors may order EMG and nerve conduction studies to evaluate the function of the affected nerves and muscles. These tests can help pinpoint the location and severity of nerve compression.

Conclusion Cervical retrolisthesis is a condition that can arise due to various causes, including degenerative changes, trauma, and congenital abnormalities. The backward displacement of the vertebrae can lead to a variety of symptoms, ranging from neck pain and stiffness to more severe complications like nerve compression and muscle weakness. An accurate diagnosis requires a comprehensive assessment involving patient history, physical examination, and advanced imaging techniques. Early diagnosis and appropriate intervention are crucial to managing symptoms and preventing further complications associated with cervical retrolisthesis.

Cervical Retrolisthesis Treatment Options:

The management of cervical retrolisthesis is multifaceted, aiming to alleviate symptoms, restore spinal stability, and improve the overall quality of life for affected individuals. Additionally, conservative approaches are often the initial line of treatment and may include physical therapy, pain management, and exercise programs designed to strengthen the supporting muscles and improve posture. In addition, doctors may prescribe nonsteroidal anti-inflammatory drugs (NSAIDs) and muscle relaxants to manage pain and inflammation.

Non-Surgical Treatments for Cervical Retrolisthesis

Non-surgical treatments focus on symptom management, reducing inflammation, restoring function, and preventing further progression of the condition. These treatments are generally preferred in cases where the retrolisthesis is mild to moderate and there are no signs of significant nerve compression or spinal cord involvement.

Physical Therapy

Physical therapy is one of the cornerstones of non-surgical treatment for cervical retrolisthesis. It focuses on strengthening the muscles surrounding the neck and improving flexibility to help stabilize the spine and reduce the strain on the affected vertebrae.

• Strengthening Exercises: Therapists design specific exercises that target the muscles supporting the cervical spine, particularly the deep neck flexors and the muscles of the upper back and shoulders. Stronger muscles help alleviate pressure on the vertebrae and improve spinal stability.
• Stretching and Flexibility: Gentle stretching exercises are prescribed to improve the range of motion in the neck, reduce stiffness, and alleviate muscle tension. Proper stretching can also relieve pressure on compressed nerves.
• Posture Correction: Poor posture, such as forward head posture, can exacerbate cervical retrolisthesis by increasing strain on the cervical vertebrae. Physical therapy programs often emphasize correcting posture through awareness, ergonomic adjustments, and specific exercises.
• Manual Therapy: Some physical therapists use manual therapy techniques such as soft tissue mobilization, joint mobilization, and myofascial release to relieve muscle tension, improve mobility, and decrease pain in the cervical spine.

Medications

Medications provide an important component of conservative treatment for cervical retrolisthesis, particularly for managing pain and inflammation. The following medications are commonly used:

• Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): Over-the-counter or prescription NSAIDs such as ibuprofen or naproxen can help reduce pain and inflammation associated with retrolisthesis. These medications are often used short-term to manage acute symptoms.
• Muscle Relaxants: If muscle spasms or tension contribute to cervical pain, doctors will prescribe muscle relaxants. These medications help ease muscle stiffness, allowing for better movement and reduced discomfort.
• Corticosteroids (Oral or Injectable): In cases where there is significant inflammation or nerve impingement, doctors will prescribe corticosteroids. Oral corticosteroids provide systemic relief, while corticosteroid injections (such as epidural steroid injections) are targeted to the affected area to reduce inflammation around nerve roots.
• Pain Relievers: Acetaminophen or other analgesics manage pain. In more severe cases, doctors may consider short-term use of opioids, though this is usually reserved for acute or post-surgical pain due to the risks of dependence.

Cervical Traction Devices

Cervical traction is a therapeutic technique used to stretch the cervical spine, helping to reduce compression on the vertebrae and alleviate pressure on the intervertebral discs and nerve roots. Traction can be performed in a clinical setting or with at-home cervical traction devices.

• Clinical Traction: Physical therapists or chiropractors may use mechanical devices or manual traction techniques to apply a controlled stretching force to the neck. This gentle traction helps create space between the vertebrae, potentially reducing retrolisthesis and alleviating nerve compression.
• At-Home Traction Devices: At-home cervical traction units are available for patients to use under the guidance of a healthcare provider. These devices are designed to provide gentle neck traction, based on the patient’s symptoms and tolerance. Doctors recommend using these devices under supervision to avoid overextension or injury.

Bracing and Immobilization

For patients with acute cervical retrolisthesis or after a significant trauma, wearing a cervical brace may provide temporary immobilization to allow the spine to heal. Cervical collars or soft neck braces help limit movement and support the cervical vertebrae.

• Short-Term Use: Bracing is generally recommended for short-term use, as prolonged immobilization can lead to muscle weakening. Braces are typically worn during the acute phase of injury or after certain procedures.

Lifestyle Modifications and Ergonomic Adjustments

Certain lifestyle changes can help prevent the worsening of cervical retrolisthesis and alleviate symptoms. These include:

• Posture Corrections: Maintaining proper posture while sitting, standing, or working can reduce strain on the cervical spine. Ergonomic adjustments, such as using a supportive chair, ensuring proper monitor height, and avoiding prolonged forward head posture, are important.
• Activity Modification: Patients are advised to avoid activities that place excessive strain on the neck, such as heavy lifting or prolonged phone use. Low-impact exercises, like swimming or walking, can help maintain fitness without exacerbating symptoms.

Surgical Treatments for Cervical Retrolisthesis

Doctors consider surgery when conservative treatments fail to relieve symptoms or when evidence suggests a neurological compromise, such as severe nerve compression, spinal cord involvement, or progressive weakness. The primary goal of surgery is to stabilize the spine, decompress affected nerves, and restore proper vertebral alignment.

Anterior Cervical Discectomy and Fusion (ACDF)

ACDF is one of the most common surgical procedures for treating cervical retrolisthesis. It is particularly useful when disc degeneration or herniation contributes to the vertebral displacement and nerve compression.

• Procedure: During ACDF, the surgeon approaches the cervical spine from the front (anterior). The damaged disc between the affected vertebrae is removed (discectomy), and the vertebrae are fused together using a bone graft or synthetic spacer. A metal plate with screws is often used to provide additional stability.
• Indications: ACDF is indicated in cases of significant disc degeneration, nerve root compression, or spinal instability. It aims to decompress the affected nerves and prevent further vertebral movement.
• Recovery: Following ACDF, the patient’s neck is typically immobilized with a brace or collar for several weeks to allow the fusion to heal. Physical therapy is initiated after recovery to restore strength and mobility.

Posterior Cervical Fusion

In some cases, the surgeon may opt for a posterior cervical fusion, which is performed from the back (posterior) of the neck. This procedure is similar to ACDF but is more suited for patients with multi-level instability or posterior ligament damage.

• Procedure: The surgeon stabilizes the cervical spine by fusing the affected vertebrae together using bone grafts and metal rods or screws placed at the back of the neck. This prevents further backward slippage and stabilizes the vertebrae.
• Indications: Posterior cervical fusion is indicated for patients with multi-level cervical retrolisthesis, significant instability, or failed anterior fusion.

Cervical Disc Replacement (Artificial Disc)

Cervical disc replacement is an alternative to fusion that preserves motion between vertebrae while relieving symptoms of retrolisthesis. It is typically indicated in cases where disc degeneration is the primary cause of vertebral displacement.

• Procedure: The damaged intervertebral disc is removed, and an artificial disc is implanted between the vertebrae. Unlike fusion, which eliminates movement, artificial disc replacement allows the patient to retain motion in the affected segment.
• Indications: Disc replacement is considered in younger patients with isolated disc degeneration who prefer to preserve mobility. However, doctors are hesitant to use it for for patients with severe instability or advanced degenerative changes.

Laminectomy or Laminoplasty

In cases of severe nerve compression or spinal stenosis due to cervical retrolisthesis, doctors will use laminectomy or laminoplasty to decompress the spinal cord or nerve roots.

• Laminectomy: The surgeon removes part of the vertebral bone (lamina) to create more space for the spinal cord and nerve roots. This reduces pressure and alleviates symptoms caused by nerve compression.
• Laminoplasty: In this procedure, the lamina is cut and restructured to enlarge the spinal canal without removing it entirely. This preserves spinal stability while creating more space for the spinal cord.
• Indications: These procedures are indicated when there is significant spinal cord compression. Especially, when it leads to myelopathy (spinal cord dysfunction) or severe neurological symptoms.

Foraminotomy

Foraminotomy is a surgical procedure aimed at enlarging the foramen, the openings through which nerve roots exit the spine. It is performed to relieve nerve compression caused by retrolisthesis or degenerative changes.

• Procedure: The surgeon removes bone spurs, disc material, or other structures that are narrowing the foramen.  This allows the compressed nerve to exit the spinal canal more freely.
• Indications: Foraminotomy is indicated when nerve root compression is causing radiculopathy (pain radiating down the arm), weakness, or numbness, and conservative measures failed.

Time to Recuperate:

The recovery period for cervical retrolisthesis varies based on the chosen treatment approach and the individual patient’s response. Conservative treatments may require several weeks to months for noticeable improvements, as patients engage in physical therapy and lifestyle modifications. Surgical recovery timelines are influenced by the complexity of the procedure, ranging from a few weeks to several months before patients can resume normal activities. Rehabilitation and postoperative care are integral components of the recovery process to ensure optimal outcomes.

Expert Opinions and Insights:

Leading experts in the field emphasize the importance of an individualized approach to treating cervical retrolisthesis. Dr. Richard A. Hostin, a renowned spine surgeon, underscores the significance of accurate diagnosis in guiding treatment decisions.
