A new concept of transforaminal ventral facetectomy
including simultaneous decompression of foraminal and lateral recess stenosis: Technical considerations in a fresh cadaver model and a literature review.
Roh, "Clinical and radiological outcomes of unilateral facetectomy
and interbody fusion using expandable cages for lumbosacral foraminal stenosis," Journal of Korean Neurosurgical Society, vol.
Using the high-speed drill, a laminectomy, medial facetectomy
, and partial lateral facetectomy
(removal of the rostral aspect of the lateral facet, down to the cranial edge of the pedicle) were then performed, similar to the open technique.
 showed that removing supraspinous/interspinous ligaments did not affect the range of motion but that total facetectomy
made the spine unstable.
The miTLIF procedures were performed using a tubular retractor for total facetectomy
, diskectomy, and interbody fusion, followed by percutaneous instrumentation.
"Layla's case was more complicated and also required an osteotomy (the surgical removal of a part of bone), facetectomy
(where a part of the vertebral joint is removed to alleviate nerve compression) and spine correction to ease the extreme curvature in her spine," explained Dr Firas M.
A monosegmental or multisegmental laminectomy above and below the extent of the tumor was performed, completed with partial facetectomy
on tumor side in order to increase the view in only two cases.
Patellofemoral osteoarthritis treated by partial lateral facetectomy
: Results at long-term follow up.
One neuron was investigated per animal because of the irreversible nature of the [L.sub.5/6] facetectomy
According to published surgical series, conventional open posterior midline approaches have typically been used to treat extradural schwannomas, requiring a dorsal midline incision, wide-ranging bilateral disruption to the paraspinal muscles and ligaments (major contributors to the maintenance of proper spine biomechanics), extensive laminectomy (from one or two levels above and below the tumor), radical foraminotomy, and complete unilateral facetectomy
[7, 10, 13, 14].
The company's new minimally invasive facetectomy
removal instrument, iO-Tome, was cleared by the FDA in October last year, and Baxano plans to release it in the fourth quarter of 2013.
