'''Posterior Ramus Syndrome''', also known as '''dorsal ramus syndrome''', is a condition characterized by pain and dysfunction associated with the [[posterior ramus]] of a [[spinal nerve]]. The posterior ramus is responsible for innervating the deep muscles and skin of the back.

Posterior Ramus Syndrome, also known as dorsal ramus syndrome, is a condition characterized by pain and dysfunction associated with the posterior ramus of a spinal nerve. The posterior ramus is responsible for innervating the deep muscles and skin of the back.

Anatomy[edit]

The spinal nerve is a mixed nerve that emerges from the spinal cord. It divides into two primary branches: the anterior ramus and the posterior ramus. The posterior ramus innervates the erector spinae muscles and the facet joints of the spine.

Pathophysiology[edit]

Posterior Ramus Syndrome occurs when there is irritation or injury to the posterior ramus. This can result from trauma, degenerative disc disease, or facet joint arthritis. The condition leads to localized pain, muscle spasm, and sometimes referred pain patterns.

Clinical Presentation[edit]

Patients with Posterior Ramus Syndrome typically present with:

  • Localized back pain
  • Muscle tenderness
  • Reduced range of motion
  • Pain that may radiate to the buttocks or thighs

Diagnosis[edit]

Diagnosis is primarily clinical, based on the patient's history and physical examination. Imaging studies such as MRI or CT scan may be used to rule out other conditions. Diagnostic nerve blocks can confirm the involvement of the posterior ramus.

Treatment[edit]

Treatment options include:

Prognosis[edit]

With appropriate treatment, many patients experience significant relief of symptoms. However, chronic cases may require ongoing management.
