Lumbar Bilateral Perched Facet Dislocation

Lumbar bilateral perched facet dislocation is a severe injury of the lower spine in which both facet joints of one vertebral segment slip out of their normal alignment, causing the vertebra above to move forward onto the one below. This condition typically arises from high-energy trauma and can threaten spinal stability, injure neural elements, and impair mobility. Understanding this injury requires a clear definition, knowledge of its various forms, and insight into the many ways it can occur, present clinically, and be accurately diagnosed.

Lumbar bilateral perched facet dislocation refers to the displacement of both superior articular facets of one lumbar vertebra slipping over the inferior articular facets of the vertebra below, without fully locking, resulting in a perched (partially dislocated) position. Unlike a locked facet dislocation, in which the facets are completely disengaged, a perched facet remains partially in contact, but may still compress nearby nerves and destabilize the spine.

Types of Lumbar Bilateral Perched Facet Dislocation

Type 1: Anterior Perched Facet Dislocation. Here, the upper vertebra shifts forward relative to the one below, causing the facets to rest in a perched position rather than their normal groove. This is the most common form and typically results from forward-bending injuries.

Type 2: Posterior Perched Facet Dislocation. In this rare pattern, the upper vertebra moves backward, pushing its facets onto the back of the inferior facets. These injuries often result from forceful extension or direct rear impact to the back.

Type 3: Rotational Perched Facet Dislocation. A twisting force causes one side of the vertebra to perch while the opposite side may partially lock or remain in place. This rotational injury can pinch nerve roots asymmetrically and lead to uneven symptoms.

Type 4: Combined Translation-Rotation Dislocation. Some injuries include both forward or backward translation and rotation, producing a complex perched orientation. These mixed-pattern dislocations often accompany more severe soft tissue damage and higher risk of nerve injury.

Causes of Lumbar Bilateral Perched Facet Dislocation

  1. Motor Vehicle Collisions. High-speed crashes can force the spine into sudden flexion or rotation, exceeding the tolerance of facet joints and leading to perched dislocations.
  2. Falls from Height. Landing on the feet or buttocks from a significant height transmits compressive forces to the lumbar spine, potentially shearing the facets into a perched position.
  3. Sports Injuries. Contact sports like football or rugby can involve tackles or falls that hyperflex or hyperrotate the torso, stressing facet joints beyond their limits.
  4. Crush Injuries. Heavy objects crushing the lower back can produce a distraction force, prying the facets apart and allowing them to perch.
  5. Severe Hyperflexion. Sudden bending forward, such as diving into shallow water, can disengage facets slightly and leave them perched.
  6. Hyperextension Trauma. Bending far backward, like in a fall onto the lower back, may drive the facets into a perched posture in reverse.
  7. Axial Loading. Vertical force down the spine, as when landing feet-first, can jam the facets together or shear them sideways into a perched position.
  8. Direct Blow to the Back. A focused impact to the lumbar region can displace facet joints without fracturing the vertebra, resulting in perched dislocation.
  9. Degenerative Facet Hypertrophy. Enlarged, arthritic facets can alter joint mechanics and predispose to subluxation under minor trauma.
  10. Osteoporosis. Weak, porous bones and compromised joint support can allow minor forces to dislocate facets.
  11. Rheumatoid Arthritis. Inflammatory damage to ligaments and joint capsules around the facets increases laxity and risk of perched dislocation.
  12. Spondylolysis. A defect or fracture in the pars interarticularis can destabilize the vertebra and ease facet slippage.
  13. Previous Spinal Surgery. Surgical disruption of ligaments or removal of stabilizing structures can leave the spine vulnerable to dislocation.
  14. Congenital Facet Anomalies. Unusual facet shapes or orientations at birth can compromise joint stability over time.
  15. Spinal Tumors. Lesions that erode bone or invade ligaments around the facets may weaken support and lead to dislocation.
  16. Spinal Infections. Osteomyelitis or discitis can destroy joint and ligament tissue, causing instability and perched facets.
  17. Chronic Steroid Use. Long-term steroids reduce bone density and weaken soft tissues around the spine.
  18. Connective Tissue Disorders. Conditions like Ehlers-Danlos syndrome increase joint laxity, predisposing individuals to subluxations and dislocations.
  19. Metastatic Cancer. Secondary tumors in vertebral bodies can erode bone and joint surfaces, destabilizing facet joints.
  20. Violent Seizures. Severe convulsions can apply unpredictable forces to the spine, occasionally resulting in perched facet dislocations.

Symptoms of Lumbar Bilateral Perched Facet Dislocation

  1. Severe Low Back Pain. A sudden, intense pain in the lumbar region is often the first sign of facet dislocation.
  2. Local Tenderness. Touching or pressing on the affected vertebral level elicits sharp discomfort.
  3. Muscle Spasm. Paraspinal muscles tighten reflexively to protect the injured segment, causing stiffness.
  4. Limited Range of Motion. Bending, twisting, or extending the lower back becomes notably restricted and painful.
  5. Radicular Pain. Pain radiating down one or both legs indicates nerve root irritation from the displaced facets.
  6. Numbness. Patients may feel reduced sensation or a “pins and needles” sensation in the legs or feet.
  7. Weakness. Compression of nerve roots can lead to muscle weakness in hip flexors, knee extensors, or ankle dorsiflexors.
  8. Reflex Changes. Altered knee or ankle reflexes point to specific nerve root involvement.
  9. Gait Disturbance. Difficulty walking or dragging of the foot may occur if motor nerves are compromised.
  10. Cauda Equina Syndrome. Severe cases may disrupt bowel or bladder control, signaling urgent spinal cord involvement.
  11. Postural Deformity. A visible step-off or misalignment may be palpable or noticeable on inspection.
  12. Pain on Extension. Leaning backward often worsens symptoms as the facets contact more forcefully.
  13. Pain on Rotation. Turning the torso can grind displaced facets and intensify pain.
  14. Referred Buttock Pain. Discomfort may spread to the buttocks or posterior thigh.
  15. Sciatica. Sharp, shooting pain following the sciatic nerve path indicates nerve root compression.
  16. Allodynia. Non-painful stimuli like light touch may feel painful near the injury.
  17. Hyperalgesia. Exaggerated response to painful stimuli reflects nerve sensitization.
  18. Swelling. Soft tissue edema may develop around the injury site.
  19. Bruising. Hemorrhage under the skin can produce visible ecchymosis over the lumbar region.
  20. Shock Signs. In traumatic settings, low blood pressure and rapid pulse may accompany severe pain and blood loss.

Diagnostic Tests for Lumbar Bilateral Perched Facet Dislocation

Physical Examination Tests

  1. Inspection. Observe posture, alignment, and any visible deformity in the lumbar region, noting asymmetry or step-offs.
  2. Palpation. Gently press along the spinous processes and facets to locate tenderness and muscle spasm.
  3. Range of Motion Assessment. Ask the patient to bend forward, backward, and side to side to evaluate pain-limited movement.
  4. Straight Leg Raise (SLR) Test. With the patient supine, lift the straightened leg to detect radicular pain suggesting nerve root irritation.
  5. Adam’s Forward Bend Test. In standing, bending forward may accentuate facet displacement and reveal contour changes.
  6. Neurological Examination. Check motor strength, sensation, and reflexes in the lower extremities to identify nerve involvement.
  7. Gait Analysis. Observe the patient walking to detect limp, foot drop, or balance issues.
  8. Palpation for Step-off. Run fingers along adjacent spinous processes to feel for a sudden forward shift.

Manual Orthopedic Tests

  1. Kemp’s Test. While standing, the examiner extends, rotates, and side-bends the patient’s spine toward the painful side; a positive test reproduces pain at the facets.
  2. Facet Joint Compression Test. Applying gentle pressure on the posterior pelvis can provoke facet pain.
  3. Extension-Rotation Test. In prone position, lifting and rotating one hip stresses the facet on that side, causing discomfort if injured.
  4. Prone Instability Test. The patient lies prone with legs off the table; lifting the legs engages stabilizing muscles—if pain decreases, passive stability is compromised.
  5. Vertebral Spring Test. Gentle anterior pressure on spinous processes tests segmental mobility; excessive movement indicates instability.
  6. Gillet’s Test. Assessing posterior superior iliac spine and sacrum movement during one-leg stance reveals sacroiliac and lower lumbar involvement.
  7. Lateral Shift Test. Observing trunk lateral deviation during forward bending helps identify asymmetric facet injury.
  8. Quadrant Test. Combining extension, rotation, and lateral bending, this test compresses the facet joint and reproduces pain.

Laboratory and Pathological Tests

  1. Complete Blood Count (CBC). Evaluates infection or bleeding, which may accompany open injuries or systemic trauma.
  2. Erythrocyte Sedimentation Rate (ESR). Elevated in inflammation or infection that can weaken joint structures.
  3. C-Reactive Protein (CRP). A more sensitive marker of acute inflammation than ESR.
  4. Coagulation Profile. Ensures safe imaging and surgery by detecting bleeding disorders.
  5. Blood Type and Cross-match. Prepares for possible transfusion in severe trauma cases.
  6. Metabolic Panel. Checks kidney and liver function before using contrast agents.
  7. Creatine Kinase (CK). High levels may indicate muscle injury around the spine.
  8. Blood Gas Analysis. Monitors oxygenation and acid-base status in critical trauma patients.

Electrodiagnostic Tests

  1. Nerve Conduction Study (NCS). Measures the speed and strength of signals traveling through peripheral nerves.
  2. Electromyography (EMG). Records electrical activity of muscles to detect denervation from nerve root compression.
  3. Somatosensory Evoked Potentials (SSEP). Evaluates conduction through sensory pathways in the spinal cord.
  4. Motor Evoked Potentials (MEP). Tests motor pathway integrity by stimulating the brain and recording muscle responses.
  5. F-wave Latency Test. Assesses proximal nerve segment function by measuring late responses in motor nerves.
  6. H-reflex. Evaluates the monosynaptic reflex arc in the S1 nerve root.
  7. Reflex Latency Testing. Quantifies delay in reflex responses, indicating nerve damage.
  8. Paraspinal Mapping. Multi-site EMG of paraspinal muscles to localize nerve root lesions.

Imaging Tests

  1. Plain Radiographs (X-rays). AP and lateral views reveal perched facets as step-offs between vertebrae.
  2. Oblique X-rays. Highlight facet joint alignment and show displaced articular processes.
  3. Flexion-Extension Radiographs. Dynamic images assess stability by comparing alignment in different positions.
  4. Computed Tomography (CT) Scan. Offers detailed bone images to define facet orientation and any fractures.
  5. Magnetic Resonance Imaging (MRI). Visualizes soft tissues, ligaments, discs, and neural elements for associated injuries.
  6. CT Myelography. Combines CT imaging with contrast in the spinal canal to outline nerve root compression.
  7. Bone Scintigraphy. Detects increased uptake at sites of acute injury or occult fracture.
  8. Ultrasound. Point-of-care evaluation can identify soft tissue swelling and guide injections or aspirations.

9. High-impact sports until cleared by your surgeon.
10. Skipping follow-up or ignoring warning symptoms.


Frequently Asked Questions

  1. Can bilateral perched facets heal without surgery?
    No—because the posterior ligamentous complex is disrupted, bracing alone cannot restore stability; surgery is almost always required.

  2. How long until I can walk normally?
    Most people begin assisted walking within 2–3 days post-op and unassisted walking by 1–2 weeks, pending pain and surgeon clearance.

  3. Will I need a fusion?
    Yes—instrumented fusion across the injured level prevents future displacement and pain.

  4. How long does the surgical hardware stay in?
    Typically permanently, unless it causes pain or rare complications.

  5. What are the biggest surgical risks?
    Infection, bleeding, nerve injury, non-union (pseudoarthrosis), and hardware failure.

  6. When can I return to work?
    Sedentary jobs: 4–6 weeks. Manual labor: 3–6 months, depending on strength recovery.

  7. Is permanent back pain inevitable?
    With proper surgery and rehab, many regain near-normal function—but mild stiffness or discomfort can persist.

  8. Do I need lifelong NSAIDs?
    No—short courses for postoperative pain, then taper as you progress in rehab.

  9. Can physical therapy harm my fusion?
    When guided by a trained therapist following surgeon protocols, therapy is safe and essential.

  10. Are there alternatives to spinal fusion?
    For this injury type, fusion is standard. Motion-preserving implants aren’t indicated for unstable facet dislocations.

  11. Will I need a brace after surgery?
    Often for 6–12 weeks to support soft tissues as they heal.

  12. How do I know if my spinal cord was harmed?
