This study introduces a flexible stainless steel cable system for posterior cervical fusion, offering an easier and safer alternative to traditional rigid wires for improved spinal stability.

Area of Science:

  • Neurosurgery
  • Orthopedic Surgery
  • Spinal Fusion Techniques

Background:

  • Cervical instability from fracture/dislocation or subluxation requires fusion.
  • Traditional rigid stainless steel wires present challenges in posterior cervical fusion insertion and tensioning.

Purpose of the Study:

  • To describe a novel posterior cervical fusion technique using flexible stainless steel cables.
  • To evaluate the safety and efficiency of this cable system as an alternative to monofilament wires.

Main Methods:

  • A flexible, 49-strand stainless steel cable with a blunt leader and islet was utilized.
  • The cable system was applied in various posterior cervical fusion techniques, including occipitocervical and atlantoaxial fusions.
  • A tension/crimper device was used to secure the cable loop and achieve desired tension.

Main Results:

  • The flexible cable system demonstrated superior biomechanical strength compared to traditional wires.
  • Greater ease of insertion and tension adjustment was observed due to cable flexibility.
  • The technique proved safe and efficient for posterior cervical arthrodesis in both upper and lower cervical spine.

Conclusions:

  • Flexible stainless steel cables offer a safe and efficient alternative for posterior cervical fusion.
  • This novel cable system overcomes the limitations of rigid wires, improving graft construct conformation and tensioning.
  • The technique is suitable for a range of posterior cervical fusion applications, enhancing surgical outcomes.
