This approach can allow undercutting of the facet joint (ventral facetectomy), discectomy, mobilization, neurolysis of the exiting and traversing nerve roots, and ablation of osteophytes.
Most of the dumbbell spinal hemangiomas described in the literature were resected using a posterior microsurgical approach with laminectomy or hemilaminectomy, and with or without facetectomy and costotransversectomy (Table 1).
Partial facetectomy may be performed in patients with traumatic lumbosacral dislocationtofacilitatereduction[34, 46, 70, 85, 99], although intact apophyseal joints are preferred to prevent redislocation [34].
Schwannomas of the lumbar region were treated with posterior laminectomy/laminotomy, extended with facetectomy, or even a transpeduncular approach in selected patients with dumbbell tumors.
Based on the basis procedure type the market is segmented into major procedures such as discectomy, laminectomy, foraminectomy, facetectomy, corpectomy among others.
This new code covers endoscopic decompression of the spinal cord, nerve root(s), including laminotomy, partial facetectomy, foraminotomy, discectomy and/or excision of herniated intervertebral disc, 1 interspace, lumbar, and will be enforced as of January 1st, 2017.
