Abstract: An expandable intervertebral implant (20) is provided for insertion into an intervertebral space defined by adjacent vertebrae. The expandable intervertebral implant includes a pair of outer sleeve portions (30A, 30B) and an inner core (50) disposed between the outer sleeve portions. Movement of the inner core relative to the outer sleeve portions causes the outers sleeve portions to deflect away from each other, thereby engaging the expandable intervertebral implant with the vertebrae and adjusting the height of the intervertebral space.

The particles of the shaped article are present in the form of interlocked particles, whereby the interlocking of said particles is obtained in a 100% water-saturated atmosphere.

Abstract: An expandable implant for treating bone preferably in a minimally invasive manner includes a preferably cylindrical core element extending along a longitudinal axis and preferably a plurality of nestable, expandable sleeves extending along a longitudinal axis for placement radially about the core element. The plurality of nestable sleeves are sequentially insertable over the core element in such a manner that a first nestable sleeve is inserted over the core element and each subsequently inserted nestable sleeve is received between the core element and the previously inserted nestable sleeve such that the insertion of each additional sleeve causes each previously inserted sleeve to outwardly expand.

Also provided are first and second fasteners, with the first fastener adapted to fit to the proximal end of the anchoring member, and the second fastener adapted to fit to the proximal end of the locking member. The end of the second fastener can have an angle that matches an angle of the locking member.

Abstract: A simplified external bone fixator assembly is provided which allows the surgeon to snap a bone fixation rod into the assembly at any location along the length of the rod. The invention does not require “threading” of the assembly onto the rod starting at the end and sliding it down the length of the rod to the desired location. In particular, a bone pin locking assembly is provided for use with standard bone fixation rods and bone pins. The assembly includes a bone pin vise, a single-piece fixation rod attachment member and a coupling to allow relative adjustment of pin vise and rod attachment member. The single-piece rod attachment member has two opposing jaws that loosely capture the bone fixation rod when the surgeon presses the rod into the attachment member. The assembly may be rigidly fixed to the rod using a bolt which tightens the attachment member onto the rod.

Abstract: A bone clamp moving bone segments relative to each other. The clamp comprises a first and second branch and a bridge connecting the first and second branch. The bone clamp may have a first, undeformed state, where the branches may be angled or substantially parallel with respect to each other. The bone clamp may have a second, deformed state, where the branches may be moved from the first state. The bone clamp may be deformed using an instrument such as pliers. When the bone clamp is in the deformed state, the branches may be inserted into bone segments. Thereafter, the instrument may be disengage from the bone clamp and the clamp may return to its undeformed state. While returning to the first, undeformed, state the bone clamp may apply compressive or distraction forces on the bone segments, thereby moving the bone segments relative to each other.

Abstract: The invention relates to an osteosynthesis implant (1) that preferably consists of a bioresorbable plastic material. The inventive implant receives the longitudinal fixation elements (10) to be anchored in the bone, especially in the form of wires, nails, pins or screws. The openings destined to receive the fixation elements (10) do not completely extend through the implant (1) like in conventional bone plates or intramedullary nails but are degenerated to indents (2) in the surface of the implant (1) so that they may serve as a guide for the fixation elements (10) to be guided through the implant (1). The inventive implant (1) allows insertion of the fixation elements (10) in the bone diverging angles and crossing one another, so that the fixation elements (10) extending intramedullarly or in the spongiosa are primarily prevented from migrating in a proximal or distal direction.
