Cervical bilateral perched facet refers to a specific type of neck injury in which both the left and right facet joints at a single cervical level become partially displaced but not fully dislocated. Facet joints are small, paired joints on the back of each vertebra that guide and limit motion. In a perched facet injury, the tip of the inferior articular process of the vertebra above “perches” on the superior articular process of the vertebra below without sliding fully past it. When this occurs bilaterally at the same level, it indicates a more unstable situation than a unilateral perched facet and carries a higher risk of progressing to complete dislocation or neurological injury radiopaedia.org.
This injury typically results from a hyperflexion‐distraction force applied to the neck, often encountered in high‐energy trauma such as motor vehicle collisions, sports accidents, or falls. The ligaments that normally hold the facet joints in place—particularly the interspinous and ligamentum flavum—are stressed or partially torn, allowing the joint surfaces to lose their normal apposition. Although the vertebral bodies may remain in near‐normal alignment, the perched facets signal an unstable spinal segment that requires prompt diagnosis and often surgical stabilization to prevent progression to locked facets or spinal cord injury radiopaedia.org.
Cervical Bilateral Perched Facet occurs when both facet joints at the same vertebral level lose their normal alignment. Facet joints are small stabilizing joints on the back of the spine; in this condition, the inferior facets of the vertebra above sit abnormally on the superior facets below. Unlike a full facet dislocation, “perched” facets maintain partial contact, so the vertebrae are not completely displaced. Common causes include sudden trauma (e.g., whiplash in a car crash), progressive degeneration from arthritis, or congenital joint laxity. Patients typically experience neck pain that worsens with movement, muscle spasm, and sometimes arm pain or numbness if nearby nerves are irritated.
Types of Cervical Facet Joint Injuries
While our focus is on bilateral perched facets, it helps to understand the broader classification of cervical facet injuries based on the degree of displacement and ligamentous damage:
Vertebral Subluxation (Facet Sprain):
The earliest and mildest form involves ligamentous stretch or partial tear without any visible bony displacement on imaging. Patients may have pain and muscle spasm but no joint malalignment.Perched Facet (Partial Facet Subluxation):
Here, the articular surfaces begin to lose their snug fit. In a unilateral perched facet, only one side is affected; in bilateral perched facets, both facet joints at the same level are perched. Translation is usually less than 25% of the vertebral body’s width learningradiology.com.Locked Facet (Complete Facet Dislocation):
This represents a more severe stage in which the inferior articular process of the superior vertebra has translated fully anterior to the superior articular process below—typically more than 50% translation—and both facets can be locked in front of the lower vertebra, often causing significant angulation and kyphosis.Jumped Facet (Intermediate Dislocation):
Sometimes considered a gray zone between perched and locked facets, jumped facets have translation between 25% and 50% of the vertebral body width and carry a high risk of progressing to full dislocation.
Understanding these types helps clinicians determine the urgency of intervention. Bilateral perched facets fall under the “perched facet” category but are inherently less stable than unilateral injuries, often prompting surgical reduction and fixation.
Causes of Cervical Bilateral Perched Facet
Below are twenty evidence‐based factors and events that can lead to a bilateral perched facet injury of the cervical spine. Each cause is explained in simple, plain English.
Motor Vehicle Collisions
Rapid deceleration and forward flexion of the head during a car crash can place extreme stress on the facets, leading to perched facet injuries.Sports Trauma
High‐impact sports such as football, rugby, or gymnastics can cause sudden hyperflexion of the neck, contributing to facet subluxation.Falls from Height
Landing on the head or neck from a significant height can hyperflex the cervical spine, disrupting ligamentous support of the facets.Diving Accidents
Striking the water head‐first can abruptly force the neck into flexion against resistance, perched facets being a known risk.Physical Assault
Direct blows to the head or neck, such as in a fight, can shear the facet joints partially out of alignment.Workplace Injuries
Falls or heavy object strikes in construction or manufacturing settings may hyperflex or distract the neck enough to perch facets.Whiplash Injuries
Rapid back‐and‐forth motion of the head in rear‐end collisions can overstretch facet joint capsules.Recreational Vehicle Crashes
Motorbike or ATV accidents often involve high energy forces acting on a freely moving head, risking perched facets.Severe Axial Loading
Vertical forces transmitted down the spine—such as in improper weightlifting technique—can overload facet joints.Degenerative Facet Disease
Advanced arthritis can weaken the joint capsule, making it easier for minor trauma to perch the facets.Rheumatoid Arthritis
Autoimmune inflammation of the cervical facets can erode ligaments, predisposing to subluxations even with low‐grade trauma.Ankylosing Spondylitis
Abnormal fusion and stiffness can concentrate forces at adjacent mobile segments, risking perched facets in a fall.Congenital Cervical Instability
Developmental abnormalities of the facets or ligaments may allow subluxations under minimal stress.Osteoporosis
Fragile bone and ligament attachments can fail under stress, leading to partial loss of facet apposition.Prior Cervical Surgery
Fusion or instrumentation at one level may increase motion and stress on the adjacent facets.Tumors or Metastases
Bone‐weakening lesions in the vertebrae or facets can allow partial displacement under normal loads.Infections (e.g., Osteomyelitis)
Destructive infections can degrade facet integrity, permitting subluxation.Iatrogenic Injury
Facet damage may occur accidentally during medical procedures such as surgery or injection.Rapid Deceleration Sports
Activities like skydiving or roller coasters that abruptly slow the head can impart flexion forces.Repeated Microtrauma
Chronic, low‐level stresses—such as poor posture or repetitive overhead activity—can weaken the facet capsules over time.
Symptoms of Cervical Bilateral Perched Facet
Patients with bilateral perched facets often present a combination of local and radiating symptoms. Here are twenty common signs, each explained clearly.
Neck Pain
A sudden, sharp pain localized at the injury site often begins immediately after trauma.Muscle Spasm
The neck muscles reflexively tighten to protect the unstable segment, causing stiffness.Reduced Range of Motion
Patients struggle or refuse to move the neck due to pain and mechanical blockage.Tenderness on Palpation
Pressing along the back of the neck reproduces pain over the affected vertebral level.Facet Joint Clicking
Some may feel or hear a subtle “pop” as the perched facet surfaces rub during gentle movement.Headache
Referred pain to the head, especially at the back of the skull, can accompany facet injuries.Radicular Pain
Sharp, shooting pain may radiate down one or both arms if nerve roots become irritated.Paresthesia
Tingling or “pins and needles” in the shoulders, arms, or hands can indicate nerve involvement.Numbness
Loss of sensation in dermatomal patterns reflects pressure on specific nerve roots.Muscle Weakness
Difficulty lifting the arm or gripping objects may point to motor nerve compromise.Reflex Changes
Hyperreflexia or reduced reflexes in the biceps or triceps can occur with nerve irritation.Gait Imbalance
Severe cases with spinal cord contusion may manifest as unsteady walking.Diplopia or Dizziness
Vertebral artery compression during sudden neck movement can lead to transient vision changes or lightheadedness.Swelling or Bruising
Soft‐tissue trauma around the neck may produce visible swelling or ecchymosis.Difficulty Swallowing
Edema and muscle spasm in the cervical region can make swallowing uncomfortable.Voice Changes
In rare cases, edema around the larynx or vagus nerve irritation may alter the voice.Shoulder Pain
Referred pain to the trapezius or shoulder blade is common in facet injuries.Scapular Dyskinesis
Uneven shoulder blade movement may result from muscle spasm or nerve root irritation.Sleep Disturbance
Patients often cannot find a comfortable position, leading to insomnia or restless sleep.Anxiety or Fear of Movement
The sudden onset of pain and instability may lead to a psychological reluctance to move the neck.

Light pressure along the spinous processes and facet joints identifies focal tenderness.Spurling’s Test
With the neck extended and rotated toward the painful side, a downward force is applied; reproduction of radicular pain suggests nerve root irritation.Distraction Test
Upward traction on the patient’s head that relieves arm pain indicates nerve compression at the facet level.Compression Test
Axial load on the head in neutral position reproducing neck pain suggests facet joint involvement.Valsalva Maneuver
Bearing down increases intrathecal pressure; worsening of pain can indicate neural structure compression.Lhermitte’s Sign
Passive neck flexion causing an electric shock–like sensation down the spine suggests spinal cord involvement.Jackson’s Test
Rotation of the head to the opposite side while applying axial compression reproducing radicular pain also points to nerve root compression.Tenderness‐Point Localization
The examiner pinpoints the exact painful spot over the facets by palpating in a grid pattern.Observation of Posture and Guarding
Visible muscle contraction, head tilt, or protective bracing are noted as signs of underlying instability.
Manual and Provocative Tests
Kemp’s Test
With the patient seated, the spine is extended, rotated, and side-bent toward the painful side; reproduction of symptoms localizes facet involvement.Vertebral Artery Test
Extended neck rotation held for 30 seconds checks for dizziness or vision changes, ruling out vascular compromise.Spring Test (Posterior-to-Anterior Mobilization)
Applying a gentle posterior-to-anterior force on each spinous process assesses segmental mobility and pain reproduction.Shear Test
Lateral-to-medial pressure on the lateral masses evaluates facet stability and pain response.Flexion-Rotation Test

Frequently Asked Questions
What exactly is a perched facet?
A perched facet is a partial misalignment of the small joints at the back of the spine. The joint surfaces “perch” on each other, causing pain and limited movement.How does it differ from a full dislocation?
In a full dislocation, one vertebra shifts completely off the one below. A perched facet maintains partial contact, so it’s less severe but still painful.Can it heal on its own?
Mild cases may improve with rest, physical therapy, and anti-inflammatory measures. Severe or chronic perched facets often need medical intervention.Is surgery always required?
No. Many patients respond well to conservative treatments. Surgery is reserved for persistent pain, neurological deficits, or instability.How long does recovery take?
With proper therapy, most people see improvement in 6–12 weeks. Complete healing can take several months.Can I continue working?
Light-duty work is often possible. Avoid heavy lifting and extreme neck movements until cleared by your doctor.Are there long-term complications?
Untreated perched facets can lead to arthritis, chronic pain, and reduced neck mobility over time.Do I need imaging?
X-rays or MRI are useful to confirm the diagnosis and rule out fractures or disc herniations.Are facet injections helpful?
Yes. Steroid or PRP injections under imaging guidance can reduce inflammation and promote healing.Will a cervical collar weaken my neck?
Prolonged use can lead to muscle atrophy. Use collars only short-term under medical advice.Is physical therapy painful?
Properly guided therapy should not significantly increase pain; any discomfort is kept within tolerable limits.Can I drive with a perched facet?
If you can comfortably turn your head and have no neurological deficits, driving is generally safe.What’s the role of ergonomics?
Proper workstation setup and posture reduce repetitive stress on the neck, aiding recovery and prevention.Are supplements really effective?
Supplements like glucosamine and omega-3s can support joint health and reduce inflammation when used consistently.How can I prevent recurrence?
Maintain neck strength, practice good posture, use ergonomic supports, and avoid high-risk activities.
