Abstract
A fixation system includes a plate intended to be positioned against a bone and which includes a plurality of threaded holes for receiving the pegs. The threaded holes define respective axes at least two of which are oblique relative to each other. When the pegs are inserted axially through their respective holes, the pegs are relatively divergent from each other. The pegs are also angularly adjustable relative to the hole axes and can be independently fixed in selectable orientations; i.e., the pegs are multidirectional, so as to provide a surgeon selected angular adjustment relative to the hole axes.
Claims29
A fracture fixation system, comprising:
- a) a substantially rigid plate having a bone contacting surface and a plurality of holes having an internal threaded, said holes defining at least two axes which are oblique relative to each other;
- b) a plurality of pegs each having a head and a shaft, said shaft sized to be received through said threaded holes, wherein said pegs when received within said threaded holes are capable of being in an angular orientation relative to respective axes through said holes;
- and
- c) a plurality of set screws engageable with said internal threads of said threaded holes for applying a force to said heads of said pegs to limit angular movement of said pegs relative to said holes.
A fracture fixation plate, comprising:
- a substantially rigid plate having a plurality of holes adapted to individually receive fixation pegs therein, said holes having an upper portion and a lower portion, said upper portion having a first internal thread, and said lower portion having a substantially spherical radius of curvature, said first internal threads of said holes defining respective axes at least two of said axes being oblique relative to each other.
