What is it about?

Facet Joint- and Nuchal Ligament-Sparing Laminectomy (FNL) is not inferior to conventional open-door laminoplasty in terms of clinical or radiologic outcomes, reducing the detachment of muscle from each lamina. The surgical concept in FNL is to spare the facet joints and nuchal ligament, providing laminectomy of approximately 20 mm in width with deviation to the side of dominant symptoms.

Why is it important?

In conventional open-door laminoplasty, excessive stripping of the posterior cervical muscles as a preparatory step is inevitable in the creation of bilateral gutters. Facet joint- and nuchal ligament-sparing laminectomy (FNL) reveals clinical and radiologic outcomes that are noninferior to those of conventional open-door laminoplasty in patients withcervical myelopathy due to degenerative cervical spine diseases. Instead, FNL appeared less invasive in that muscle detachment from each lamina was reduced, potentially maintaining the cervical motion compared with open-door laminoplasty.


Simple procedure. Good outcome. Easy postoperative management. Cost effective.
