Thinly traded nano cap Xtant Medical Holdings (NYSEMKT:XTNT) is up 16% premarket, albeit on turnover of only 2,200 shares, in response to its announcement that wholly owned subsidiary X-spine Systems has received FDA clearance of its Xspan Laminoplasty Fixation System.
Laminoplasty is a surgical procedure to relieve pressure on the spinal cord due to stenosis (narrowing of the canal). It involves cutting a portion of the vertebrae called the lamina to relieve the compression. The lamina is then restructured by a small plate that allows the spinal canal to increase in size without losing stability or movement in the vertebrae.
