Posterior Ramus Syndrome

Posterior ramus syndrome—also known as thoracolumbar junction syndrome, Maigne syndrome, or dorsal ramus syndrome—is a condition in which the primary division of a posterior ramus (dorsal ramus) of a spinal nerve becomes activated without clear cause. This activation irritates the dorsal ramus and produces a characteristic tri-branched pattern of referred pain, often without pain at the actual lesion site. Diagnosis is purely clinical, based on four variable criteria: (1) pain in one of three well-defined skin territories, (2) absence of spontaneous pain at the spinal level, (3) normal findings on routine imaging, and (4) relief of pain following a local anesthetic injection into the affected facet joint en.wikipedia.org.

Posterior ramus syndrome—also called thoracolumbar junction syndrome, Maigne syndrome, or dorsal ramus syndrome—is a form of back pain caused by irritation of the dorsal (posterior) ramus of a spinal nerve. This branch divides into three “sclerotomal” pathways, producing referred pain in the groin/pubis, lower back/upper gluteal region, and anterolateral thigh/trochanter region. Diagnosis is clinical, based on characteristic referral patterns, absence of spontaneous pain at the spine level, non-contributory imaging, and relief with a diagnostic anesthetic block into the affected facet joint en.wikipedia.org. Anatomical studies confirm that the medial, intermediate, and lateral branches of the posterior ramus follow consistent zones over the transverse processes, providing a basis for targeted injections and interventions frontiersin.org.

Types

1. Pathomechanism-Based Variants

Posterior ramus syndrome can be divided into two main variants. The central variant arises from nerve afferent activity triggered by degenerative or arthropathic changes in the thoracolumbar facet joints. The peripheral variant results from entrapment of cutaneous branches—most commonly the superior cluneal nerves—leading to similar referral patterns of pain pubmed.ncbi.nlm.nih.gov.

2. Anatomical-Level Classifications

Depending on the spinal level involved, dorsal ramus syndrome may present as:

• Cervical Dorsal Ramus Syndrome (CDRS): Irritation of cervical dorsal rami causing neck pain and referred pain into the head or upper limbs e-neurospine.org.

• Thoracic Dorsal Ramus Entrapment: Compression of thoracic dorsal rami (e.g., at T3–T5) by bony spurs or costotransverse ligaments, producing mid-back and chest wall sensory disturbances pubmed.ncbi.nlm.nih.gov.

• Thoracolumbar Junction Syndrome (Maigne Syndrome): Involves dorsal rami at the T12–L1 junction, with referral to groin, buttock, and lateral thigh regions en.wikipedia.org.

• Lumbar Dorsal Ramus Syndrome (LDRS): Irritation of L1–L5 dorsal rami, distinguished from discogenic pain by absence of nerve-root compression signs pubmed.ncbi.nlm.nih.gov.
