Abstract: The present invention relates to a vertebral osteosynthesis plate to maintain relative vertebral orientation correction using a correction instrument. The osteosynthesis plate has an overall rectangular shape and comprises at least four slots to insert, in each, fixation devices, wherein at least two of the slots opens onto a lateral edge of the osteosynthesis plate to enable positioning and fixation of the plate with no prior removal of the relative vertebral orientation correction instrument. The edge of the plate is defined by an edge located in the same direction as the longitudinal direction of the plate. The longitudinal direction of the plate is roughly identical to that of the direction of the spinal column.

Abstract: The present invention concerns a method and equipment for drilling bone, in particular for setting a pedicle screw using a manual or motorized drilling tool. The equipment includes a drilling instrument, a source of electric impulses and a connector for connecting the electric impulse source to the drilling instrument. The equipment includes at least one sensor for detecting a muscle signal either implanted in a muscle or placed on the skin in the vicinity of a muscle before and during drilling. An alert is produced in the event of detection by at least one sensor of a muscle signal correlated with the source of electric impulses connected to the drilling instrument.

Abstract: The present invention relates to an interbody spinal stabilization method and an interbody spinal stabilization cage. The cage has a parallelepipedic shape and comprises a central hollow space intended to be filled with bone fragments. The cage also comprises anchoring device(s) having an overall S shape and opening onto lateral faces connecting with adjacent vertebrae, actuated by at least one actuation device opening into a front face. The anchoring device(s) each have at least one main cutting edge.
