Differential Diagnosis for Popping Sensation in the Neck

• Single most likely diagnosis
  • Cervical spondylosis or cervical spine osteoarthritis: This condition is characterized by wear and tear on the cervical spine, leading to popping or cracking sensations in the neck due to the movement of joints and ligaments.
• Other Likely diagnoses
  • Cervical facet joint syndrome: Inflammation or irritation of the facet joints in the cervical spine can cause popping sensations, along with pain and stiffness.
  • Cervical disc herniation: A herniated disc in the cervical spine can cause a popping sensation, as well as pain, numbness, and weakness in the neck and arms.
  • Temporomandibular joint (TMJ) disorder: Although primarily affecting the jaw, TMJ disorders can radiate pain and cause popping sensations to the neck area.
• Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
  • Cervical spine fracture or instability: A fracture or instability in the cervical spine can cause a popping sensation and is a medical emergency, as it can lead to spinal cord injury or paralysis.
  • Vertebral artery dissection: A tear in the vertebral artery can cause a popping sensation in the neck, and if left untreated, can lead to stroke or death.
  • Cervical spinal cord injury: Trauma to the cervical spine can cause a popping sensation and is a medical emergency, as it can lead to paralysis or death.
• Rare diagnoses
  • Atlantoaxial subluxation: A rare condition where the joint between the atlas (C1) and axis (C2) vertebrae becomes unstable, causing a popping sensation in the neck.
  • Cervical ligamentous laxity: A condition where the ligaments in the cervical spine become loose, causing excessive movement and popping sensations in the neck.
