Study Notes

Cervical Radiculopathy

  • The cervical spine consists of vertebrae C1-C8, with C1 labeled as the "Atlas" and C2 as the "Axis".
  • Nerve root entrapment occurs due to narrowing of intervertebral foramina and/or the spinal canal, caused by:
    • Disc pathology (extrusion and/or protrusion)
    • Degenerative disc disease (DDD)
    • Osteoarthritis (OA)
    • Osteophytes
    • Facet joint degeneration or hypertrophy

Clinical Presentation

  • Impairments:
    • Radiating pain, numbness, and tingling
    • Muscle weakness and atrophy
  • Activity limitations and participation restrictions:
    • Difficulty with ADLs involving the upper extremity (UE)
    • Impaired bathing, dressing, and toileting abilities
    • Difficulty with writing, grasping, feeding, and driving

Medical Management

  • Pharmacological interventions:
    • NSAIDs
    • Epidural steroid injection (reduces inflammation, provides temporary relief for 3-6 months)
  • Surgical procedures:
    • Decompression surgery (laminectomy, discectomy, fusion)

Conservative Management

  • Goals of physical therapy:
    • Centralize symptoms
    • Manage pain using heat, cold, ultrasound, electrical stimulation, and mechanical traction
    • Postural education and training
    • Stretching and resistance training to address patient impairments

Cervical Degenerative Disc Disease

  • Pathophysiology:
    • Degeneration of the disc as part of the normal aging process
    • Loss of disc height due to nucleus pulposus (NP) dehydration
    • Disc becomes stiffer, and the annulus becomes weaker (increasing the risk of tears)
  • Types of disc degeneration:
    • Protrusion (aka prolapse)
    • Herniated:
      • Extruded: NP outside the annulus, limited by the posterior longitudinal ligament
      • Sequestrated: NP outside the posterior longitudinal ligament and into the central canal

Disc Degeneration Stages

  • Healthy disc
  • Prolapse: disc starts to bulge out
  • Extrusion: disc is entirely outside its original position
  • Sequestration: disc is completely broken, and some of its content has migrated
