Study Notes
Cervical Spine Overview
- The cervical spine is susceptible to degenerative changes such as arthritis.
- Disc and nerve root pathologies can occur.
- Trauma can cause indirect (e.g., whiplash) or direct (e.g., impact) injuries.
Cervical Spine Anatomy (C1-C7)
- The cervical spine consists of seven vertebrae (C1-C7).
- Structures like transverse processes, spinal canal, spinous process, lamina, and pedicles are key components.
- Important lateral neck muscles include splenius, levator scapulae, sternocleidomastoid, scalene, thyrohyoid, omohyoid, trapezius, and deltoid.
Atlas and Axis (C1 and C2)
- The atlas (C1) connects the skull to the cervical spine.
- The axis (C2) is a crucial component in transmitting load from the atlas to the rest of the spine.
- The dens (odontoid process) is a projection on the axis that acts as a fulcrum.
Ligamentous Anatomy
- Anterior longitudinal ligament: Reinforces anterior discs and limits extension.
- Posterior longitudinal ligament: Reinforces posterior discs and limits flexion.
- Ligamentum nuchae (supraspinous ligament): Thicker in the cervical region than other parts of the spine.
- Interspinous/intertransverse ligaments: Limit flexion and rotation/lateral flexion.
- Ligamentum flavum: Attaches laminae of vertebrae, reinforcing articular facets. It limits flexion and rotation.
Palpable Landmarks
- C7 is palpable.
- Anterior curvature is present.
Spinal Nerves
- C1-T1 nerves form the cervical plexus.
- C1-C4 nerves form the phrenic nerve crucial for breathing.
- C4-T1 nerves form the brachial plexus, supplying nerves to the arm.
Dermatomes/Myotomes
- Dermatomes define sensory areas associated with specific spinal nerves.
- Myotomes define muscle groups controlled by specific spinal nerves.
- Relevant examples provided for C1-T1.
Brachial Plexus
- The brachial plexus is a network of nerves originating from C5-T1.
- Five peripheral nerves stem from this network, including the Musculocutaneous, Axillary, Radial, Median, and Ulnar nerves.
- Detailed branching patterns are described.
Cervical Injuries
- Cervical injuries are relatively rare in athletics but are associated with a high percentage of fatalities.
- Common mechanisms include tackling, falling, spearing, and whiplash.
- Assessing emergency plans concerning personnel roles, equipment, and the importance of initially assuming the worst-case scenario are critical.
- Types of injuries include fractures, dislocations, nerve root injuries, herniated discs, and cord shock. Specific examples of common MOIs (Mechanisms of Injury) are presented.
Cervical Spine Evaluation
- Evaluation procedures like Observation, Palpation, Special Tests, HOPS, and History are emphasized.
- Establishing spinal cord and nerve root integrity is the first priority.
- Important aspects of history include location, onset, and consistency of pain, and past history.
Location of Pain, Onset, Consistency and History
- Localized pain usually points to muscular strain, ligaments, fractures, or subluxations.
- Radiating pain suggests increased risk of spinal cord, cervical nerve root, or brachial plexus injury.
- Acute onset pain frequently correlates to a mechanism of injury.
- Chronic pain often results from overuse, poor posture, and repetitive movements.
- Prior history of cervical spine injury is significant and must be carefully assessed.
