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.
published the results of an investigation of pedicle screw implantation.
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.
5mm x 50 mm), pedicle markers, depth sleeves, dilator, marker inserter/extractor, cannulated taps, cannulated locking screw drivers and guidewires.

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.
