  • Z-shaped boneplate and the method for internal fixation of long bone fractures and allograft materials
    Patent number: 5133718
    Abstract: The present invention provides a kind of boneplate for fixation of long bone fracture and allograft materials in humans and mammals. It is a Z-shaped boneplate, which fixes the fractured bone internally by inserting the boneplate into the boneslot. A Z-shaped boneplate is made up of an upper flange member and a lower flange member and both related to a web member. Its cross section is a Z-section beam. The surgical procedure concerning this invention mainly involves cutting a proper boneslot and inserting the boneplate into the boneslot, thus making the upper and lower flanges abut the inner and outer cortexes respectively and avoid bending and torsion between the fractured ends and any displacement between the cross sections of the fractured ends, therefore, provide stable locking of the fractured ends.
