Abstract
The invention is related to medicine and, in particular, to a class of implants intended for osteosynthesis i.e. in the treatment of essentially all kinds of bone fractures. It is the aim of the present invention to eliminate the above contradiction and to design a bone implant and a spacer thereof that would not cause periosteum necrosis and osteoporosis of the bone and also a method of placing a bone implant of the kind. This aim is achieved by using polytetrafluorethylene, in particular, in the form of a porous surface three-dimensional structure as a spacer for a support surface of a bone implant.
Claims9
A bone implant, comprising:
- an apertured plate having a support surface substantially conformal to fractured portions of a bone treated using the implant;
- and
- a spacer disposed on the support surface of the apertured plate,
- wherein the spacer is fabricated from a solid non-mesh block of biologically inert material capable, under influence of mechanical loads exerted on the spacer by the apertured plate, to undergo gradual in-situ recrystallization resulting in contraction of a thickness of the spacer.
