Cervical Spine Sprain

Cervical spine sprain—often called a neck sprain or, in the context of high-speed collisions, “whiplash”—is an injury in which one or more ligaments that stabilize the cervical vertebrae (C1–C7) are overstretched or torn. This can occur from rapid acceleration–deceleration forces, direct blows, or excessive bending and twisting of the neck. The result is inflammation, pain, and potential instability of the cervical segment NCBIMedscape.

Anatomy of the Cervical Spine

Structure and Location

The cervical spine comprises seven vertebrae (C1–C7) forming a flexible column between the base of the skull and the thoracic spine. Each vertebra consists of a vertebral body, pedicles, laminae, transverse processes (unique for their transverse foramina), and spinous processes, creating an S-shaped curvature that balances head weight and protects the spinal cord KenhubNCBI.

Ligament Origins and Insertions

• Anterior Longitudinal Ligament (ALL): Runs along the anterior surfaces of vertebral bodies from the occiput to the sacrum, preventing hyperextension Kenhub.

• Posterior Longitudinal Ligament (PLL): Lies within the vertebral canal along the posterior surfaces of vertebral bodies from C2 to the sacrum, restraining flexion Kenhub.

• Ligamentum Flavum: Connects the laminae of adjacent vertebrae, preserving normal curvature and elastic recoil during extension Kenhub.

• Interspinous and Supraspinous Ligaments (including Ligamentum Nuchae): Span between spinous processes (C7 to occiput for the nuchal ligament), limiting flexion KenhubKenhub.

• Craniovertebral Ligaments (Alar & Apical):

  • Alar Ligaments: From the dens of C2 to the occipital condyles, stabilizing rotation Kenhub.

  • Apical Ligament: Apex of the dens to the foramen magnum, assisting in stability of the atlanto-occipital joint Kenhub.

Blood Supply

Arterial supply to the cervical vertebrae and ligaments primarily derives from:

• Vertebral arteries traversing the transverse foramina of C1–C6, which also supply the spinal cord and posterior cranial fossa KenhubPhysio-pedia.

• Ascending cervical and deep cervical arteries (branches of the thyrocervical trunk), which give off segmental branches to vertebral bodies, ligaments, and intervertebral discs Kenhub.

Nerve Supply

• Recurrent meningeal (sinuvertebral) nerves (from ventral rami of C1–C8) innervate the PLL, dura, facet joints, and ligaments, conveying pain and proprioception PMCKenhub.

• Medial branches of the dorsal rami supply the facet joint capsules.

• Cervical plexus (C1–C4) and brachial plexus roots (C5–T1) lie adjacent to the vertebrae, carrying motor and sensory fibers to muscles and skin of the neck NCBITeachMeAnatomy.

Functions

1. Head Support: Bears the weight of the head (~4.5–5 kg) and transmits load to the thoracic spine Kenhub.

2. Spinal Cord Protection: Encases and shields the cervical spinal cord within the vertebral canal.

3. Flexion/Extension: Permits nodding and tilting motions (e.g., looking up/down).

4. Lateral Flexion: Enables side-to-side bending of the neck.

5. Axial Rotation: Allows turning the head as in looking over the shoulder.

6. Shock Absorption: Intervertebral discs and ligamentous tension dampen vertical and shear forces during movement.

Types of Cervical Sprain

1. Grade I (Mild): Ligament stretch without fibrous disruption; minimal pain, full range of motion Physio-pedia.

2. Grade II (Moderate): Partial ligament tear with decreased range of motion and point tenderness. Patients have musculoskeletal signs (e.g., swelling) but no neurological deficits Physio-pedia.

3. Grade III (Severe): Complete ligament tear or avulsion, often with instability and neurological signs (sensory deficits, diminished reflexes, weakness) Physio-pediaPhysio-pedia.

4. Acute vs. Chronic:

   • Acute Sprain: Symptoms appear within 72 hours of injury.

   • Chronic Sprain: Persistent pain and instability >6 weeks, often from inadequate healing.

5. Whiplash-Associated Disorders (WAD): Classification by the Quebec Task Force:

   • Grade 0: No neck complaints or physical signs.

   • Grade I–III: Align with the above grades.

   • Grade IV: Neck injury with fracture or dislocation Physio-pedia.
