Posterior Cord Syndrome: Symptoms and Treatment
Posterior cord syndrome is a rare but significant condition that affects the spinal cord. Understanding its symptoms, diagnosis, prognosis, and treatment options is crucial for medical professionals and patients alike.
These columns are responsible for transmitting sensations of delicate touch, vibration, and proprioception (the sense of body position) to the brain.
Causes of Posterior Cord Syndrome
The causes of posterior cord syndrome are varied and can include traumatic injuries, such as fractures or dislocations of the vertebrae, and non-traumatic factors, like tumours, infections, and degenerative diseases. Understanding the root cause is essential for proper diagnosis and treatment.
Pathophysiology
The dorsal columns of the spinal cord, which are most affected in posterior cord syndrome, consist of white matter tracts that carry sensory information to the brain. Damage to these tracts can lead to a loss of sensory function below the level of injury, while motor function often remains intact.

Recognizing the symptoms of posterior cord syndrome is vital for timely diagnosis and intervention. The symptoms can vary depending on the extent and location of the injury but generally include:
Sensory Loss
Patients with posterior cord syndrome typically experience a loss of delicate touch, vibration, and proprioception below the level of the spinal cord injury. This sensory loss can significantly impact daily activities and quality of life.
Motor Function
Interestingly, motor function is usually preserved in patients with posterior cord syndrome. This preservation is because the motor pathways, located in the anterior and lateral columns of the spinal cord, remain unaffected.
Ataxia
Another common symptom is ataxia or a lack of coordination. This condition arises due to the loss of proprioception, making it challenging for patients to perform precise movements.
Other Symptoms
Additional symptoms may include urinary incontinence, sexual dysfunction, and altered reflexes, depending on the level and severity of the spinal cord injury.
Diagnosis of Posterior Cord Syndrome
Accurate diagnosis is crucial for effective treatment and management of posterior cord syndrome. The diagnostic process typically involves a combination of clinical evaluation, imaging studies, and electrophysiological tests.
Clinical Evaluation
The first step in diagnosing posterior cord syndrome is a thorough clinical evaluation by a neurologist or spinal cord specialist. This evaluation includes a detailed medical history, physical examination, and assessment of sensory and motor function.
Imaging Studies
Imaging studies, such as magnetic resonance imaging (MRI) and computed tomography (CT) scans, play a pivotal role in diagnosing posterior cord syndrome. These studies help visualize the extent and location of the spinal cord injury and identify any underlying causes, such as fractures or tumours.
Electrophysiological Tests
Electrophysiological tests, including somatosensory evoked potentials (SSEPs) and nerve conduction studies, can provide additional information about the integrity of the sensory pathways in the spinal cord. These tests are valuable in confirming the diagnosis and assessing the severity of the injury.
Treatment for Posterior Cord Syndrome
The treatment for posterior cord syndrome aims to address the underlying cause, alleviate symptoms, and improve the patient's quality of life. The treatment approach can vary depending on the etiology of the syndrome and the severity of the injury.
Medical Management
Medical management is often the first line of treatment for posterior cord syndrome. This approach can include:
- Medications: Pain relievers, anti-inflammatory drugs, and muscle relaxants may be prescribed to manage symptoms and reduce inflammation.
- Steroids: High-dose corticosteroids may be administered in acute cases to minimise swelling and inflammation around the spinal cord.
- Antibiotics: If an infection is the underlying cause, antibiotics are essential for treating the infection and preventing further damage.
Surgical Intervention
In some cases, surgical intervention may be necessary to address the underlying cause of posterior cord syndrome. Surgical options can include:
- Decompression Surgery: This surgery aims to relieve pressure on the spinal cord caused by fractures, tumours, or herniated discs.
- Spinal Stabilization: If the spinal column is significantly unstable, surgical stabilization may be required to prevent further injury.

Rehabilitation plays a crucial role in the recovery and management of posterior cord syndrome. A comprehensive rehabilitation program may include:
- Physical Therapy: Physical therapy focuses on improving strength, coordination, and mobility. Therapeutic exercises and gait training can help patients regain function and independence.
- Occupational Therapy: Occupational therapy aims to enhance daily living skills and adapt the patient's environment to promote independence.
- Psychological Support: Coping with a spinal cord injury can be challenging, and psychological support is essential for addressing emotional and mental health needs.
Prognosis of Posterior Cord Syndrome
The prognosis of posterior cord syndrome can vary widely depending on factors such as the cause, extent of the injury, and timeliness of treatment. While some patients may experience significant improvement with appropriate treatment and rehabilitation, others may have persistent symptoms.
Factors Influencing Prognosis
Several factors can influence the prognosis of posterior cord syndrome, including:
- Age: Younger patients generally have a better prognosis due to greater neuroplasticity and regenerative potential.
- Severity of Injury: The extent of damage to the dorsal columns and other spinal cord structures can significantly impact the prognosis.
- Timeliness of Treatment: Early diagnosis and prompt treatment can improve outcomes and reduce the risk of complications.
