Risks associated with a laminectomy include:
- damage to the spinal cord or other nerves
- weakening or loss of function in the legs
- blood clots
- leakage of spinal fluid resulting from...
tears in the dura, the protective membrane that covers the spinal cord
- worsening of back pain
Laminectomy is a spine operation to remove the portion of the vertebral bone called the lamina. There are many variations of laminectomy, in the most minimal form small skin incisions are made, back muscles are pushed aside rather than cut, and the parts of the vertebra adjacent to the lamina are left intact. The traditional form of laminectomy (conventional laminectomy) excises much more than just the lamina, the entire posterior backbone is removed, along with overlying ligaments and muscles. The usual recovery period is very different depending on which type of laminectomy has been performed: days in the minimal procedure, and weeks to months with conventional open surgery.
More than 60 percent of procedures neurosurgeons perform are spine-related, according to the National Neurosurgical Procedural Statistics 2006 Survey from the American Association of Neurological Surgeons (AANS).
