摘要:
A bone plate secured by both a screw and a post. The head of the post may act as a cam that prevents screw backout. Preferably, the shaft of the first post passes partially through the first post through hole so that the distal unthreaded portion of its shaft substantially extends beyond the plate and the proximal threaded portion of its shaft substantially remains in the first post through hole.
摘要:
Plate-based fixation system having dual anchors. The plate can include cams. The plates can have a banana-shape. The plates can be adapted to receive a polyaxial bone screw. The plates can be jointed so as to be height-adjustable.
摘要:
A separate nub component between the plate and an intervertebral fusion cage, wherein the nub is attached to the plate. The nub lessens the undesired pivotal movement of the plate. It is believed that when the nub fits snugly between the endplates of the adjacent vertebral bodies, it acts as a stop against the undesired pivotal movement of the plate.

摘要:
An access device for providing access from a skin incision to a surgical site is described. The access device has a first section having a proximal end and a distal end defining a first path therethrough. The access device has a second section having a proximal end and a distal end defining a second path therethrough, the second section is movable relative to the first section, and the first and second sections cooperate to form a continuous path such that movement of the second section changes the length of the path.
摘要:
A surgical access system for providing access to a surgical site in a patient includes a surgical access device defining a port and a light emitter coupled to the surgical access device for illuminating the port. The light emitter preferably comprises an elongated shaft having a light transmitting element housed therein, which emits light transmitted to the elongated shaft from a light source. The elongated shaft is configured to be inserted in an elongated channel in the access device. The elongated channel has or forms a window for transmitting light emitted by the light emitter into the interior of the access device.

摘要:
A method of trialing an intervertebral disc space, including the steps of creating the disc space, inserting a trial into the disc space, wherein the trial has i) a distal head having an upper surface and a lower surface connected by a pair of side walls, the side walls defining planes, and ii) a proximal rod, so that the head and rod form an obtuse angle and the rod extends through at least one of the planes defined by the side walls of the head.
