Title:
BONE FRACTURE FIXATION MEANS
Document Type and Number:
WIPO Patent Application WO/2011/089564
Kind Code:
A1
Abstract:
A bone fracture fixation plate juxta-articular stabilisation means comprises a plate with integral pin and tail parts, a plate specific jig, a plate and jig specific drill sleeve, a slotted head top loading screw, a plate positioner and a pin bender. This system can be used for fixation of most types of fractures involving the juxta-articular radius. The plate has a most juxta-articular row of screw holes in individually bendable and detachable extensions especially designed for very juxta-articular or the volar lip fractures. The plate also has bendable and detachable pin part and tail parts on either ends that allows the plate to be used with a chuck as a wire or drill bit and also have longer purchase into the bone with minimal soft tissue exposure. The plate and targeting assembly have plate positioning slots for wires in its juxta-articular part to allow adjustment in position of plate in longitudinal, transverse and oblique directions after initial fixation with wires without committing to a screw hole. This allows a very precise placement of the plate in the most ideal position. The targeting assembly can be mounted onto the plate prior to surgery thus reducing surgical step and time. The specific orientation of the screw holes in the shaft part of the plate orientates the screws such that when tendons apply forces across the fracture, the plate is wedged between screw and the bone rather than pushed away from the bone. Therefore, more aggressive physical therapy can be commenced earlier or plates with fewer screws in the proximal part can be used without compromising the strength of the fixation.
