Thoracic Bilateral Complete Facet Dislocation

Thoracic bilateral complete facet dislocation is a serious spinal injury in which both facet joints at a thoracic vertebral level are completely displaced. This injury results in extreme instability of the spine, risking damage to the spinal cord and nerves. Although more common in the neck (cervical spine), bilateral facet dislocations can occur in the mid‐back (thoracic) region after high‐energy trauma. Understanding its types, causes, and warning signs, as well as how to diagnose it, is vital for prompt treatment and good recovery.

Thoracic bilateral complete facet dislocation is a severe spinal injury in which both the left and right facet joints of one or more adjacent thoracic vertebrae become entirely displaced, leading to a loss of normal alignment and function of the spinal column. This injury typically results from extreme flexion–distraction forces applied to the spine, such as those encountered in high-speed motor vehicle collisions or falls from height, causing the inferior facets of the superior vertebra to slip anteriorly over the superior facets of the inferior vertebra by 100% or more pubmed.ncbi.nlm.nih.govradiopaedia.org. Clinically, it often presents with intense mid-back pain, deformity on inspection, and potentially severe neurological deficits if the spinal cord or nerve roots are compromised mdpi.compmc.ncbi.nlm.nih.gov. Early recognition via radiography and CT scanning is critical, as unrecognized dislocations can lead to progressive instability, neurological deterioration, and chronic deformity pubmed.ncbi.nlm.nih.govmdpi.com.

In a healthy spine, each vertebra connects to the one below it through paired facet joints. These small, strong joints guide movement and keep the spine stable. In a bilateral complete facet dislocation, both joints at the same level slip entirely out of position, so that the vertebra above shifts forward relative to the one below and locks in place. This displacement breaks the normal alignment and can pinch or tear the spinal cord, leading to pain, paralysis, or other serious problems. Evidence shows that without quick recognition and surgical realignment, patients face permanent nerve damage and severe disability¹. Early and accurate diagnosis through thorough tests is essential to reduce long‐term harm.

Types of Thoracic Bilateral Complete Facet Dislocation

While all bilateral facet dislocations share the feature of complete displacement, clinicians often describe sub-types based on imaging and injury patterns:

1. Perched Facet Dislocation
   Both facets are partially perched on each other without full locking. The joints are misaligned but not fully locked, making reduction somewhat easier.

2. Locked Facet Dislocation
   Facets are completely locked together, forming a fixed forward shift of one vertebra. This is the classic “complete” type requiring surgical release.

3. Rotational (Posterolateral) Dislocation
   In addition to forward shift, one or both facets rotate slightly, producing a twisted deformity. This can complicate reduction maneuvers.

4. Translation (Anterior) Dislocation
   The entire vertebra translates straight forward relative to the one below, often with a perched or locked facet on each side.

5. Multi-Level Dislocation
   Although rare, dislocations can involve more than one thoracic level in very severe traumas, demanding complex surgical planning.

Causes

Each cause below increases stress on the thoracic facet joints or involves trauma that can push facets out of place:

1. High-Speed Motor Vehicle Collision
   Rapid deceleration forces thrust the upper body forward, placing huge shear stress on the thoracic facets, causing them to dislocate.

2. Fall from Height
   Landing on the feet or buttocks can compress the thoracic spine, driving one vertebra forward over the next.

3. Direct Blow to the Thoracic Spine
   Sports collisions or industrial accidents that strike the mid-back with force can pop facets out of their sockets.

4. Diving Injury
   Hitting water at high speed head-first can hyperextend and shear the upper back, dislocating facets.

5. Hyperflexion Injury
   Sudden bending of the back beyond its normal range tears ligaments and allows facets to slide forward.

6. Hyperextension Injury
   Extreme backward bending stresses posterior ligaments, opening facet joints and leading to dislocation.

7. Rotational Forces
   Twisting the torso violently can rotate facet joints out of alignment on both sides.

8. Compression Fracture with Displacement
   When a vertebral body fractures and collapses, its collapse can lever the facets forward.

9. Asian Seat-Belt Positioning
   Improper lap belt placement across the abdomen rather than pelvis focuses force on the thoracic spine.

10. Osteoporosis
    Weakened bone can compress unevenly, leading to facet instability and eventual dislocation under lower stresses.

11. Ankylosing Spondylitis
    Stiff, fused segments transfer stress to adjacent mobile levels, risking dislocation at the interface.

12. Tumor-Related Bone Erosion
    Spine tumors can erode facet joint surfaces, weakening their hold and increasing chance of slip.

13. Infection (Osteomyelitis)
    Infection can weaken bone and ligaments around facets, permitting easier displacement.

14. Iatrogenic (Surgical Complication)
    Excessive resection of bone or ligaments during spine surgery can destabilize facets and cause dislocation.

15. Chronic Degenerative Facet Arthritis
    Worn cartilage and lax ligaments allow abnormal sliding of vertebrae under load.

16. Thunderclap Lifting Injury
    Lifting a very heavy load without spine support can hyperload facets suddenly, popping them out.

17. Dysplastic Facet Joint Anatomy
    Congenital shallow or irregular facets predispose them to slip under normal forces.

18. Ligamentous Laxity Disorders
    Conditions like Ehlers–Danlos syndrome weaken ligaments, making facet dislocation easier.

19. Repetitive Microtrauma
    Athletes or workers with repeated thoracic strain can gradually loosen facets until complete dislocation occurs.

20. Electrical Shock Falls
    Sudden muscle spasms and loss of balance from shocks can lead to uncontrolled falls injuring the thoracic spine.

Frequently Asked Questions

1. Q: What exactly is facet joint dislocation?
   A: It is when the small joints between vertebrae slip out of place, causing instability and pain radiopaedia.orgcambridge.org.

2. Q: Can thoracic facet dislocation heal without surgery?
   A: Minor subluxations may be managed conservatively, but complete bilateral dislocations typically require surgical reduction and stabilization to prevent chronic deformity and neurologic injury pubmed.ncbi.nlm.nih.govpreprints.org.

3. Q: How long is recovery after surgery?
   A: Most patients require 3–6 months of rehabilitation, with gradual return to activities over 12 months jtss.orgpreprints.org.

4. Q: Are high-dose steroids always recommended?
   A: Steroid use is controversial; guidelines suggest considering methylprednisolone within 8 hrs of injury but weigh risks of infection and bleeding pmc.ncbi.nlm.nih.govmedcentral.com.

5. Q: When can I start physiotherapy?
   A: Gentle breathing and isometric exercises begin within days; more intensive therapy starts after stabilization and surgeon clearance (usually 1–2 weeks) physio-pedia.comphysio-pedia.com.

6. Q: Will I regain full sensation?
   A: Neurological recovery varies; incomplete injuries have better prognosis, while complete injuries may have permanent deficits jtss.orgneurology.org.

7. Q: Are stem cells a cure?
   A: Stem cell therapies are investigational; early studies show potential but are not standard care en.wikipedia.orgpmc.ncbi.nlm.nih.gov.

8. Q: How can I prevent osteoporosis post-injury?
   A: Weight-bearing exercises when safe, vitamin D/calcium supplementation, and bisphosphonates help maintain bone density en.wikipedia.orgen.wikipedia.org.

9. Q: Is back brace necessary?
   A: A custom thoracic brace may support healing but long-term use can weaken musculature; use as directed by specialist preprints.orgen.wikipedia.org.

10. Q: Can I drive again?
    A: Driving resumes once neck and back motions are near normal, pain is controlled, and surgeon approves (often 3–6 months) jtss.orgpreprints.org.

11. Q: What exercises should I avoid?
    A: Avoid heavy lifting, twisting, and high-impact sports until fully healed physio-pedia.comen.wikipedia.org.

12. Q: Are dietary supplements effective?
    A: Supplements may support healing but should complement, not replace, medical therapy en.wikipedia.orgen.wikipedia.org.

13. Q: Can I return to work?
    A: Return-to-work depends on job demands; sedentary roles often resume sooner than manual labor jtss.orgen.wikipedia.org.

14. Q: Is spinal cord injury rehabilitation covered by insurance?
    A: Coverage varies; early liaison with payers and documentation of medical necessity are key en.wikipedia.orgen.wikipedia.org.

15. Q: What is the long-term outlook?
