Ligament Demonstrations

See how DMX captures sub-failure ligament injuries in motion — injuries often invisible on static imaging.

Alar Transverse Accessory Anterior Longitudinal Posterior Longitudinal Capsular Interspinous

Upper Cervical & Craniocervical Ligaments

These ligaments are critical for head and neck stability. DMX is often the only modality that can demonstrate their functional integrity.

Alar Ligament

C0–C1–C2 Stability

Demonstration of sub-failure stretching of the alar ligament. Note the bilateral overhang of the C1 lateral masses — a classic sign of rotational instability at the craniocervical junction.

DMX Motion Study Real-time visualization of C1 lateral mass overhang during dynamic movement.

Anatomical Reference Location and orientation of the alar ligaments.

Key Finding Bilateral C1 lateral mass overhang — hallmark of alar ligament compromise.

Why This Matters

Damaged alar ligaments can cause profound instability, dizziness, and pain that static imaging fails to explain. DMX provides the objective proof needed for diagnosis and legal documentation.

Transverse Ligament

Atlantoaxial Stability

Demonstration of transverse ligament insufficiency. Anterior translation of C1 on C2 produces an increased atlanto-dental interspace (ADI).

DMX Motion Study Clear anterior translation of C1 on C2 during flexion-extension.

Anatomical Reference The transverse ligament holds the odontoid against the anterior arch of C1.

Key Finding Pathologically increased atlanto-dental interspace (ADI).

Why This Matters

Transverse ligament injury can lead to serious atlantoaxial instability. Many patients with “normal” MRIs continue to suffer because the injury only becomes visible under dynamic stress.

Accessory Ligament

Rotational & Lateral Stability

Demonstration of accessory ligament damage. Widening of the para-odontoid space bilaterally indicates loss of secondary stabilization around the odontoid.

DMX Motion Study Dynamic widening of the para-odontoid spaces during movement.

Anatomical Reference Accessory ligaments provide secondary restraint to the craniocervical complex.

Key Finding Bilateral para-odontoid space widening.

Why This Matters

Accessory ligament injuries frequently coexist with alar and transverse damage. When all three are compromised, patients can experience severe craniocervical instability.

Lower Cervical Ligaments

Ligamentous and disc injuries in the mid and lower cervical spine are frequently missed on static studies but can produce significant pain and functional loss.

Anterior Longitudinal Ligament (ALL)

Disc & Vertebral Stability

Sub-failure injury to the ALL produces characteristic anterior disc space widening during extension — a finding often invisible on neutral or flexed static images.

DMX Motion Study Anterior disc space opening during dynamic extension.

Anatomical Reference The ALL runs along the anterior vertebral bodies and resists hyperextension.

Key Finding Pathologic anterior disc space widening confirming ALL insufficiency.

Why This Matters

ALL damage is common in whiplash-type injuries and can lead to segmental instability and accelerated disc degeneration. DMX captures the precise level and degree of instability.

Posterior Longitudinal Ligament (PLL)

Posterior Disc Protection

PLL injury allows posterior disc space widening during flexion. This finding is frequently overlooked on standard imaging yet has important implications for spinal stability.

DMX Motion Study Posterior disc space widening during controlled flexion.

Anatomical Reference The PLL lies posterior to the vertebral bodies and anterior to the spinal cord.

Key Finding Abnormal posterior disc space opening indicating PLL compromise.

Why This Matters

PLL injuries can contribute to chronic axial pain and instability. Because the injury is dynamic, it is rarely diagnosed correctly without motion imaging.

Capsular Ligament

Facet Joint Stability

Capsular ligament damage produces facet gapping and abnormal motion at the zygapophyseal joints — a common source of chronic neck pain after whiplash.

DMX Motion Study Clear facet gapping during lateral bending and rotation.

Anatomical Reference The capsular ligaments surround and stabilize the facet joints.

Key Finding Abnormal facet joint gapping confirming capsular ligament injury.

Why This Matters

Facet capsular injuries are a leading cause of chronic whiplash-associated disorders. They create painful segmental hypermobility that static imaging often misses.

Interspinous Ligament

Posterior Element Stability

Interspinous ligament damage allows excessive separation of the spinous processes during flexion — a posterior ligamentous injury that produces significant mechanical pain.

DMX Motion Study Increased spinous process separation during flexion.

Clinical Finding Widened interspinous spaces indicating posterior ligamentous disruption.

Anatomical Reference The interspinous ligaments connect adjacent spinous processes and limit flexion.

Why This Matters

Interspinous ligament injuries often coexist with other posterior element damage and contribute to segmental instability. Accurate identification helps prevent misdiagnosis as simple “muscle strain.”

Cases Traditional Imaging Missed

Patients told their MRI, CT, or X-rays were “normal.” DMX proved otherwise.

Severe Multi-Level Neck Ligament Injuries

Real case: This patient suffered for years with debilitating neck pain and instability after a motor vehicle collision. Multiple static MRIs and CT scans were reported as normal. DMX revealed extensive multi-level ligamentous damage that finally explained the symptoms and opened the door to appropriate care.

Shoulder Instability Missed on Static Imaging

Real case: Pronounced shoulder instability with supporting ligament and capsular damage that traditional static imaging completely failed to identify. DMX captured the true dynamic nature of the injury and provided objective evidence for treatment and the patient’s personal injury claim.
