Abstract:
1. A device for the fixation of two vertebra of a subject one to the other, the device comprising: an elongated member having a longitudinal axis, said elongated member terminating at a first end of said longitudinal axis in a first terminal portion and terminating at a second end of said longitudinal axis at a second terminal portion; a first securing portal defined within and passing through said first terminal portion and a second securing portal defined within and passing through said second terminal portion; said elongated member being sized and configured to extend transversely across a first vertebra of a subject such that when said device is in use and fitted in said transverse relationship to said vertebra, said first securing portal will be positioned over a first facet of said first vertebra and said second securing portal will be positioned over a second facet of said vertebra; a central portion of said elongated member connecting said first terminal portion to said second terminal portion; said central portion being upwardly displaced from said longitudinal axis so as to form an upward curvature in the central portion of said elongated member, said central portion also being displaced laterally to form a twist angle; a first and a second securing member, each having a head portion and an elongated bone penetration portion, said bone penetration portions being sized and configured to respectively pass through said first securing portal and said second securing portal and having sufficient length to also pass through a portion of bone of an adjacent first vertebra and a portion of bone of an underlying second vertebra such that when in use, said first and second securing members serve to secure the device at both the first end and the second end of said elongated member to said first vertebra and said second underlying vertebra such that said first and second vertebra are secured one to the other and at least one connection member configured to rigidly and immovably fix said first vertebra to said second vertebra.
