Cervical spinal interbody fusion with Kiel bone.

Area of Science:

• Spine surgery
• Orthopedic research
• Neurosurgery

Background:

• Cervical spondylosis is a degenerative condition affecting the cervical spine.
• Anterior cervical interbody fusion aims to stabilize the spine and decompress neural elements.
• The Kiel bone graft is a biomaterial used in spinal fusion procedures.

Purpose of the Study:

• To evaluate the efficacy of the Kiel bone graft in achieving bony fusion in anterior cervical interbody fusion.
• To assess the clinical outcomes of using Kiel bone grafts in patients with cervical spondylosis.

Main Methods:

• A retrospective review of 73 disc spaces in 65 patients undergoing anterior cervical interbody fusion with Kiel bone grafts.
• Follow-up ranged from 2 to 5 years post-operation.

Main Results:

• Bony fusion, in the true sense, was not confirmed with the use of Kiel bone grafts.
• Surgical aims, including disc and osteophyte removal, spinal fixation, and distraction, were achieved.
• Neural tissue compression was prevented, and stability of the spine was attained.

Conclusions:

• While the Kiel bone graft may not consistently lead to bony fusion, it can facilitate successful surgical outcomes in anterior cervical interbody fusion for cervical spondylosis.
• The procedure effectively addresses spinal instability and neural compression, improving patient stability.
