Abstract
Background
Cervical laminectomy is a common strategy to decompress the spinal canal.
Methods
The anatomy of the cervical spine and surrounding critical structures as viewed from the posterior approach is described. The use of a high-speed drill with a footplate attachment to make laminar troughs with an en-bloc subaxial cervical laminectomy is described with a discussion on surgical technique and complication avoidance.
Conclusion
This technique allows for a safe, comfortable, and rapid decompression of the cervical spine with minimal risk. For routine cases, this may potentially be more safe and cost-effective than using a cutting bur or bone scalpel attachment.

Clip 2
Intraoperative demonstration of a laminar cut in the cervical spine over several levels. This posterior view shows how the footplate attachment is held and positioned from the surgeon’s perspective. This is a safe and effective way to decompress the spine in the cervical and thoracic regions. Following bilateral cuts, the lamina is removed in standard fashion (MP4 6155 kb)
