Spinal Cord Compression at the L2–L3

Spinal cord compression at the L2–L3 level occurs when structures around the lumbar spinal canal—such as a herniated disc, bone spur, tumor, or inflamed ligament—press on the nerve roots or the terminal spinal cord (conus medullaris/cauda equina). This pressure disrupts nerve signaling, causing pain, numbness, weakness, or autonomic dysfunction in the lower back, hips, legs, and pelvic organs. Though true spinal cord ends at approximately L1, compression here often affects the cauda equina, presenting with saddle anesthesia, bowel/bladder changes, and lower-extremity deficits. Early recognition and intervention are crucial to prevent permanent neurological injury.

Spinal cord compression at the L2–L3 vertebral level refers to any process that impinges on neural structures within the spinal canal at this segment. Although the true spinal cord typically terminates at the L1–L2 level (the conus medullaris), compression at L2–L3 primarily affects the cauda equina nerve roots and distal spinal cord elements NCBI. Clinically, this compression can manifest acutely, subacutely, or chronically, depending on the underlying cause and rate of progression. Prompt recognition and diagnosis are vital to prevent irreversible neurologic deficits, including motor weakness, sensory loss, and autonomic dysfunction Wikipedia.

Types of Compression

Spinal cord (or cauda equina) compression can be classified by location and onset:

• Extradural Compression: Occurs when structures external to the dura mater, such as vertebral fractures, metastatic tumors, or herniated discs, impinge upon the thecal sac. This is the most common form of spinal cord compression Wikipedia.

• Intradural Extramedullary Compression: Involves lesions located inside the dura but outside the spinal cord parenchyma, including meningiomas and nerve sheath tumors. These lesions gradually narrow the spinal canal from within Wikipedia.

• Intramedullary Compression: Results from processes originating within the spinal cord itself—such as astrocytomas or ependymomas—that expand and compress adjacent neural tissue NCBI.

Compression can also be categorized by tempo:

• Acute Compression develops within minutes to hours, often due to trauma (e.g., epidural hematoma) or rapidly expanding masses Wikipedia.

• Subacute Compression evolves over days to weeks, as with epidural abscesses or slowly enlarging tumors Wikipedia.

• Chronic Compression progresses insidiously over months to years, typically from degenerative conditions like spondylosis or ligamentum flavum hypertrophy Wikipedia.

Symptoms

Localized back pain is often the earliest symptom of L2–L3 compression, typically described as a deep, aching discomfort in the lower back. Pain may intensify with standing, walking, or spinal extension and can precede neurological deficits by weeks to months. NCBIWikipedia

Radicular pain manifests as sharp, shooting pain radiating from the lumbar region into the anterior thigh or groin, reflecting irritation of emerging L2–L3 nerve roots. This type of pain often worsens with maneuvers that increase intraspinal pressure, such as coughing. NCBIWikipedia

Numbness or decreased sensation in the L2–L3 dermatomal distribution affects the anterior thigh and medial knee. Patients may report a “dead” or “sleepy” sensation in these areas, often preceding motor weakness. NCBIWikipedia

Paresthesia refers to abnormal tingling or “pins and needles” occurring in the same dermatomes. These dysesthetic sensations may be intermittent or continuous and can interfere with daily activities and sleep. NCBIWikipedia

Muscle weakness in hip flexors (L2) and knee extensors (L3) can present as difficulty climbing stairs, rising from a seated position, or maintaining balance. Weakness often correlates with the severity of compression and can progress if untreated. NCBIWikipedia

Gait disturbance may emerge from combined pain, sensory loss, and motor weakness. Patients often describe a “stiff-legged” or “cautious” gait, favoring one side to alleviate discomfort or compensate for weakness. NCBIWikipedia

Hyperreflexia below the level of compression may develop as upper motor neuron signs appear in subacute to chronic compression. Increased deep tendon reflexes, particularly at the patellar tendon (L3), signal central involvement. NCBIWikipedia

Clonus—repetitive muscle contractions following sudden stretch—can be elicited at the ankle or knee and indicates corticospinal tract irritation from chronic compression. It may precede more obvious spasticity. NCBIWikipedia

Babinski sign denotes an extensor plantar response upon stroking the lateral foot sole, reflecting pyramidal tract involvement. It is a hallmark of upper motor neuron lesion and may appear as compression advances. NCBIWikipedia

Spasticity develops over time as inhibitory supraspinal control diminishes, leading to velocity-dependent resistance to passive movement in the lower limbs. This can contribute to gait impairment and discomfort. NCBIWikipedia

Muscle atrophy in proximal thigh muscles may occur with chronic denervation and disuse. Wasting is typically observed in vastus medialis and iliopsoas, reflecting long-standing root or cord involvement. NCBIWikipedia

Sensory examination includes testing for light touch, pinprick, vibration, and proprioception across dermatomes to map sensory deficits. Precise localization aids in targeting imaging studies. NCBIWikipedia

Rectal tone assessment is critical when autonomic involvement is suspected. Reduced anal sphincter tone suggests sacral cord or cauda equina compromise, indicating urgent intervention. NCBIWikipedia

Deep tendon reflexes can be either hypoactive at the level of the lesion or hyperactive below, reflecting mixed upper and lower motor neuron involvement. Analysis of reflex changes guides lesion localization. NCBIWikipedia

Babinski test evaluates plantar response for extensor versus flexor toe movement, indicating corticospinal tract integrity. An extensor response supports upper motor neuron lesion from cord compression. NCBIWikipedia

Clonus testing involves rapid dorsiflexion of the foot to elicit rhythmic contractions, a sign of upper motor neuron involvement from chronic compressive myelopathy. NCBIWikipedia
