A locking plate system has multiple locking pins, each with one end formed as a screw to lock in the pending fixation bones or vertebral tubercles, with another end defining rectangular or similarly shaped locking post having a threaded locking end. Near the locking post end, there is formed a stopping protrusion. A plate defines multiple locking bores disposed at one side to be placed over the locking post end until the plate reaches the stopping protrusion on the locking pin. The plate defines multiple threaded screwing bores near the other side to receive locking pin screw. Multiple locking devices fix the side of the plate having locking bores to the locking post end of its locking pins. Multiple screwing pins each have one end formed as a pin to be used for penetrating the the threaded screwing bore to lock into the bone or the vertebral tubercle. Another end which forms a head is for holding against the threaded screwing bore of the plate. Threads are provided near the head for the screwing pins to be screwed within the threaded screwing bore of the plate.
A locking plate system for locking together adjacent bones or vertebral tubercles comprising: a) a plurality of locking pins, each locking pin having a threaded end adapted to be threaded into a bone or vertebral tubercle, a locking end and a stopping protrusion located between the threaded end and
A locking plate system for locking together adjacent bones or vertebral tubercles comprising: a) a plurality of locking pins, each locking pin having a threaded end adapted to be threaded into a bone or vertebral tubercle, a locking end and a stopping protrusion located between the threaded end and locking end; b) a plate defining a first plurality of locking bores adapted to non-rotatably accept the locking ends of the locking pins such that the locking ends extend through the plate thereby enabling a side of the plate facing the bone or vertebral tubercle to rest on the stopping protrusions to prevent movement of the plate toward a bone or vertebral tubercle, the plate further defining a plurality of threaded bores; c) a plurality of screwing pins, each screwing pin having a first threaded portion adapted to be threaded into a bone or vertebral tubercle and a second threaded portion adapted to be threaded into a threaded bore of the plate; and, d) locking devices engageable with the locking ends of the locking pins after they have passed through the locking bores of the plate to hold the plate assembled to the locking pins.
