Food and Drug Administration approval in 2005, enables surgeons to accurately place
pedicle screws during spinal procedures.
In the clinical practice, the insertion trajectory of screws isusually along the
pedicle axis for increasing the placement safety, but in the same time, the insertion direction must bechoosen to provide the strongest possible interface between bone and screw.
Since the
pedicle is the preferred site for fixation of posterior spine implants, this patent extends our leading intellectual property position in the facet joint replacement market worldwide," he added.
Screw fixation of the fractured
pedicles could provide accurate reduction and early union of the fractured
pedicles.

The insertion of pedicular screw, used for fixation and stabilization of the spine and for enhancing the long-term biological fusion by holding bony structures together, poses specific problems to spine surgeons mainly due to the difficulty of accurately inserting the screw without damaging the
pedicle.

Pedicle screws are bone screws implanted in the
pedicles of the spine to anchor a variety of devices used to stabilize the spine and thereby speed bone union.
SpineVision[R] announced today that preliminary data from an ongoing postmarketing study show that its FDA-cleared PediGuard[TM] device allows a two-fold reduction of the risk of inadvertent
pedicle screw "misplacement" during lumbar degenerative spine surgery.
Indeed, accuracy of
pedicle screw placement is still an important issue in spine surgery: published rates of intraoperatively 'misplaced'
pedicle screws range from 10 to 40 percent, some of which result in pathological consequences such as spinal cord damage, including paraplegia or quadriplegia.
The introduction of the "smart" PediGuard Curv
pedicle screw placement device is expected to enable SpineGuard to further penetrate the spine surgery market, as about 30% of spine surgeons prefer a "curved"-tipped probe.
