摘要:
There are provided systems and methods for positioning a connecting member adjacent the spinal column that include one or more anchor assemblies having an anchor engageable to bony structure and an extended receiver having a guide portion and an implantation portion. A connecting member is movable along the guide portion from a location outside the patient to the implantation portion in the patient, where the connecting member is secured to the anchor assembly with an engaging member. The guide portion is formed as a single unit with but separable from the implantation portion to provide a modified low-profile anchor assembly after implantation of the connecting member.

An apparatus is provided for guiding a surgical implant to a bone anchor during surgery. The apparatus includes a bone anchor extender releasably attachable to the bone anchor wherein the bone anchor extender clips onto a head portion of the bone anchor to assist in guiding the surgical implant to the bone anchor.
摘要:
Systems and methods include an anchor engage able to a vertebra and an extender removably mounted to the anchor. The extender includes an insulating member extending at least partially thereabout to electrically insulate the extender and prevent shunting of electrical signals delivered through the extender to the anchor to structures adjacent the extender.
摘要:
A spinal surgical system includes at least two extenders extending proximally from respective ones of first and second anchors engaged to the spinal column. A connecting member is positionable between the at least two extenders such that the connecting member extends between the at least two extenders. The connecting member is movable distally along the at least two extenders and engageable to the first and second anchors.

Devices, instruments, systems and techniques for guiding an implant to a location adjacent a bone anchor include a guide member with a connecting portion and a guiding portion. The connecting portion is adjacent the bone anchor, and the guiding portion extends proximally from the connecting portion and is adapted guide an implant therealong toward the bone anchor. The guiding portion is flexible to facilitate manipulation and implant placement in the patient's body.

Orthopedic medical devices for use in orthopedic procedures are provided, having in certain embodiments a first member and a second member configured to replace a disk between a first vertebra and a second vertebra. Additionally, the second member is also configured to fuse the second vertebra to at least a third vertebra. In one embodiment, the second member has a first portion that is elastic and a second portion that is substantially rigid. In other embodiments, the second member is substantially rigid. In yet another embodiment, the first member and second member are configured to replace a disk between the first vertebra and the second vertebra, and the second member and a third member are configured to replace a second disk between the third vertebra and a fourth vertebra. In this embodiment, the first, second, and third members may be connected to vertebrae by various anchors.
摘要:
A plating system for stabilization of a bony segment includes a plate engageable to at least first and second bony elements. For spinal stabilization, the plate is attached to the antero-lateral portions of at least first and second vertebrae and is structured to facilitate engagement of the plate to the vertebrae from an approach extending in the anterior-posterior directions.
摘要:
An apparatus and procedures for percutaneous placement of surgical implants and instruments such as, for example, screws, rods, wires and plates into various body parts using image guided surgery. An apparatus for use with a surgical navigation system, an attaching device rigidly connected to a body part, such as the spinous process of a vertebrae, with an identification superstructure rigidly but removably connected to the attaching device. This identification superstructure, for example, is a reference arc and fiducial array which accomplishes the function of identifying the location of the superstructure, and, therefore, the body part to which it is fixed, during imaging by CAT scan or MRI, and later during medical procedures.

Devices and methods include an anchor assembly engageable to a vertebra and a connecting element positionable through a receiver of the anchor assembly. The receiver includes chamfered surfaces along a leading end of the receiver to facilitate endwise insertion of the connecting element into the passage.
