Abstract
The invention relates to a bone fixation device which includes a pair of bone plates and a longitudinal carrier. The longitudinal carrier can be used to permit the bone plates to telescope with respect to one another, such as in a direction parallel to the longitudinal axis of the vertebral column. A joint also may be used to permit swivelling of the plates with respect to each other.
Claims41
A fixation device for connecting bone portions comprising:
- a first plate and a second plate, each plate having a top surface, a bottom surface for contacting bone, and at least one fixation bore extending from the top surface to the bottom surface;
- at least one member associated with at least one of the plates;
- and
- a releasably lockable joint,
- wherein the at least one member permits translation of the plates with respect to each other about a translation axis, and the releasably lockable joint permits swivelling of the plates with respect to each other about a swivel axis oriented transverse to the translation axis.

A fixation device for connecting bone portions comprising:
- a first plate and a second plate, each plate having a top surface, a bottom surface for contacting bone, and at least one fixation bore extending from the top surface to the bottom surface, at least one of the plates having a channel;
- at least one longitudinal member slidably associated with the channel in at least one of the plates;
- and
- a releasably lockable joint,
- wherein the at least one member permits translation of the plates with respect to each other about a translation axis, and the releasably lockable joint permits swivelling of the plates with respect to each other about a swivel axis oriented transverse to the translation axis.

A fixation device for connecting bone portions comprising:
- first and second plates, each plate having a top surface, a bottom surface for contacting bone, and a fixation bore extending from the top surface to the bottom surface;
- first and second members, each member being slidably associated with the first plate and second plate respectively;
- and
- a joint defining a first axis and comprising a clamping member disposed in a sleeve,
- wherein the members permit translation of the plates with respect to each other, the joint permits angulation of one of the plates with respect to at least one of the members about the first axis, and the clamping member is actuable with respect to the sleeve to releasably fix the angulation.
