Minimal Invasive Spine Surgery (MISS) as a surgical approach is increasingly utilized because of the advantages it offers over conventional spine surgery. The smaller incision results in decreased tissue damage, less blood loss, decreased hospital stay & faster postoperative recovery. The drawbacks of MISS are the long learning curve of working through a smaller incision, longer length of surgery, & potential higher complication rate due to compromised visual field. These limitations can be overcome by more effectively using imaging and navigational devices. The pedicle device simplifies the hardest part of MISS instrumented fusion of conventional pedicle screw insertion by introducing a percutaneous temporary device to locate and create the channel for later conventional pedicle screw implantation using available imaging techniques. This results in faster conventional pedicle screw insertion with precision, thereby decreasing implantation error and minimizing soft tissue injury and blood loss, as well as neurological, vascular, and dural injuries and complications.

Geldanamycin derivatives that block the uPA-plasmin network and inhibit growth and invasion by glioblastoma cells and other tumors at femtomolar concentrations are potentially highly active anti-cancer drugs. GA and various 17-amino-17-demethoxygelddanamycin derivatives are disclosed that block HGF/SF-mediated Met tyrosine kinase receptor-dependent uPA activation at fM levels. Other ansamycins (macbecins I and II), GA derivatives, and radicicol required concentrations several logs higher (≧nM) to achieve such inhibition. The inhibitory activity of tested compounds was discordant with the known ability of drugs of this class to bind to hsp90, indicating the existence of a novel target(s) for HGF/SF-mediated events in tumor development. Methods of using such compounds to inhibit cancer cell activities and to treat tumors are disclosed. Such treatment with low doses of these highly active compounds provide an option for treating various Met-expressing tumors, in particular invasive brain cancers, either alone or in combination with conventional surgery, chemotherapy, or radiotherapy.
