PediGuard is a handheld device capable of alerting surgeons to potential pedicular
or vertebral breaches.
A possible explanation is that these larger core sizes were due to removing the trocar too soon, thereby sampling a greater proportion of healthy pedicular
Repair of defects in spondylolysis by segmental pedicular
screw hook fixation.
4,5) If symptomatic, a vertebrectomy with fusion of the bodies and support by posterior pedicular
instrumentation is usually sufficient to provide pain relief.
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.
It is now possible to insert morselized particles of bone allograft into a compressed vertebra utilizing a percutaneous, unilateral, para pedicular
approach with a moderate-sized coaxial cannula system.
PediGuard is the first patented, wireless, handheld instrument capable of accurately detecting changes in tissue type, thus alerting surgeons to potential pedicular
or vertebral breaches during pedicle screw site preparation.
The shrew delivered a series of rapid bites to the membranous region between the pedicular
plate and the telson (stinger), severing the telson from the body.
