摘要:
The present invention discloses an alignment guide apparatus, system, and method. The alignment guide apparatus includes a body, a fixation insert, a guide pin, and a screw. The body may include an arm with a first end and a second end, an attachment portion at the first end, and an alignment portion at the second end. The fixation insert may be configured to pass through the attachment portion and the guide pin may be configured to pass through the alignment portion. The screw may be configured to engage the guide pin. The alignment system may include a bone plate, an alignment guide, a screw, at least one first fastener, and at least one second fastener. A method for moving a joint is also disclosed.

A distractor device (10) may include a tubular body (13) being internally threaded (19), a first foot plate (11) extending from the tubular body, and an internal post (14) in the tubular body. The internal post may include a first portion (16) having a first diameter being externally threaded (26) to cooperate with the internally threaded tubular body, and a second portion (17) coupled to the first portion, having a second diameter less than the first diameter, and also being externally threaded (18). The tubular body may include a longitudinal slot extending from adjacent the first foot plate. The distractor device may include a second foot plate (20) extending through the longitudinal slot and for threadingly coupling to the externally threaded second portion of the internal post. The second portion may include a tool interface (15) on a distal end thereof.

The various embodiments of the present invention provide a system, including methods, apparatus and kits for stabilizing and compressing bone fractures using a compression plate apparatus for stabilizing bone fragments with compression comprising a plate having at least two bone screw holes adapted to accept at least one bone screw each, the plate additionally having at least one elongate hole through the plate; a rack comprising rack teeth located along at least one linear edge of the elongate hole; a pinion axle assembly comprising a pinion axle having a head portion, a pinion gear having complementary gear teeth for engaging the rack teeth and a lower portion having threads for engaging bone, whereby when a first bone screw is anchored in bone through a bone screw hole in the plate and the pinion axle assembly is anchored in a portion of bone across a fracture from the anchored bone screw through the elongate hole in the plate, then rotation of the pinion gear causes sliding motion of the unanchored bone fragment relative to the plate.
摘要:
This invention is anatomically contoured anterior cervical plates (2) with bone ingrowth surfaces, providing for intersegmental compressive pre-loading, and a rigid and locked interface to all of the bone screws (30), with those engaging the vertebrae deployed in highly convergent pairs. Said plates comprising: a recess for retaining a locking element for locking bone screws in said bone screw receiving holes, said recess having a central longitudinal axis offset from a transverse line passing through the central longitudinal axes of said first and second bone screw receiving holes, and a locking element movably engageable in said recess, said locking element being movable from at least a first position to a second position when engaged to said plate, said locking element being configured so as to permit insertion of bone screws into each of said first and second bone screw receiving holes when said locking element is in said first position and is engaged to said plate.

This invention is anatomically contoured anterior cervical plates (2) with bone ingrowth surfaces, providing for intersegmental compressive pre-loading, and a rigid and locked interface to all of the bone screws (30), with those engaging the vertebrae deployed in highly convergent pairs. Said plates comprising: a locking element for locking at least two of said bone screws inserted in bone screw receiving holes, respectively, said locking element adapted to be coupled to said plates prior to the insertion of said bone screws into said bone screw receiving holes, said locking element being moveable from an initial position that permits the insertion of at least one of said bone screws into said bone screw receiving holes to a final position that is adapted to retain at least two of said bone screws to said plates.
