This study introduces the cervical claw device (CCD) for treating upper cervical instability, offering a viable option for patients with osteoporosis or thin occipital bone. The CCD method demonstrated effective pain relief and stabilization of neurological symptoms in all patients.

Area of Science:

  • Neurosurgery
  • Orthopedic Surgery
  • Spinal Fusion Techniques

Background:

  • Occipitocervical fixation is crucial for treating upper cervical instabilities.
  • Traditional fixation methods using screws or wires are unsuitable for patients with severe osteoporosis or thin occipital bone.

Observation:

  • A clinical trial evaluated a novel fixation method utilizing cervical interlaminar hooks and occipital claws (CCD type).
  • Six patients (five women, one man; age 28-72) with nontraumatic upper cervical instabilities were treated with the CCD system.
  • The CCD system features rod plates with hooks for interlaminar and occipital placement; occipital screws can also be used.

Findings:

  • No postoperative complications were reported.
  • All patients experienced significant improvement in neck pain.

  • Neurological symptoms improved or stabilized in all four affected patients.

    • Implications:

    • The cervical claw device (CCD) is effective for correcting various upper cervical instabilities.
    • This method is particularly beneficial for patients with compromised bone quality, such as osteoporosis or thin occipital bone.
    • The CCD system offers a promising alternative fixation method in complex spinal cases.
