摘要:
A bone fixation device. The bone fixation device includes a receiver having a deformable portion, a bone fastener having a head, the head insertable into the receiver from the deformable portion, and a retaining member couplable to the deformable portion. The retaining member deforms the deformable portion and angulatably retains the fastener relative to the receiver.

An anterior cervical plating system for securing multiple bone segments relative to each other includes a plate member having multiple pairs of nodes. Each node defines a bone screw aperture. Linking segments connect the pairs of nodes to one another. Between adjacent linking segments are elongated viewing windows. The bone screw apertures each include an integral locking mechanism to ensure that the bone screws do not back out of the plate member. The locking mechanisms and the bone screw apertures allow for angular freedom of insertion of the bone screws into a vertebral body or other bone portion.

An apparatus for external fixation of the pelvis includes first and second pluralities of bone screws adapted to be connected to first and second portions of the pelvis, respectively. The apparatus additionally includes a first bone screw clamp for receiving the first plurality of bone screws and a second bone screw clamp for receiving the second plurality of bone screws. Further, the apparatus includes a frame for securing the first bone screw clamp to the second bone screw clamp. The frame includes a transversely extending member which is articulable between a first position and a second position such that the transversely extending member is displaced in an inferior/superior direction when the frame is articulated from the first position to the second position.
摘要:
An external fixator for securing a first bone portion in a position relative to a second bone portion. The fixator includes a first clamping assembly for receiving a first bone screw connected to the first bone portion and a second clamping assembly for receiving a second bone screw connected to the second bone portion. The first and second clamping assemblies are interconnected by a main body which includes a plurality of serrated joints. Each serrated joint preferably includes first and second overlapping flanges which carry cooperating serrated surfaces adapted to selectively interlock. Each joint includes a fastener defining a pivot axis, the fasteners being operative to mechanically separate the cooperating serrated surfaces upon rotation in a first direction.

A method of preparing a surgical plan comprises video capturing a range of motion of an anatomic joint of a patient to obtain a range of motion video, registering the range of motion video to two-dimensional images of a skeleton of the patient, identifying potential impingement and stability issues in the anatomic joint based on the range of motion video, templating a prosthetic implant on two-dimensional images of the anatomic joint using the identified potential impingement and stability issues of the anatomic joint to obtain position and orientation data, and electronically saving the position and orientation data of the prosthetic implant for use with a surgical navigation system. A system for planning and performing a surgical procedure comprises a motion capture system, an x-ray system, an electronic modeling system, and a surgical navigation system.

An orthopedic device can include an intramedullary nail and an insert telescopically received in the intramedullary nail. The insert includes at least two guiding bores for corresponding bone fasteners that can be locked at an angle to the intramedullary nail. A locking set screw can be coupled to the insert and move the insert to a position that locks the bone fasteners to the nail.
摘要:
An external fixator for adjustably securing a first bone portion in a position relative to a second bone portion. The fixator includes a first clamping assembly for receiving a first bone screw connected to the first bone portion and a second clamping assembly for receiving a second bone screw connected to the second bone portion. The first and second clamping assemblies are interconnected by a connection member. The external fixator also includes a drive unit for controlling angular adjustment of the second clamping assembly relative to the first clamping assembly.
摘要:
An implantation apparatus for preparing adjacent vertebral bodies to receive an intervertebral implant including a plurality of keels. The implantation apparatus includes an elongated handle portion, and a template portion carried at a distal end of the handle portion substantially perpendicularly to the handle portion. The template portion defines a plurality of open channels corresponding in position and shape of the plurality of keels. Each channel is positioned and shaped for preparing a vertebral opening to receive a corresponding keel.

A system for performing osteotomies includes a bone plate and a retractor assembly. The bone plate generally includes a first mounting portion for attachment to a first bone portion, a second mounting portion for attachment to a ssecond bone portion, and an intermediate portion connecting the first mounting portion and the second mounting portion. The retractor assembly includes first and second handle members coupled for relative movement about a first pivot axis and first and second jaw members coupled to the first and second handle members, respectively.
