摘要： A new top-loading transverse connector of the present invention for bridging between longitudinal members of a spinal fixation system implant. The transverse connector is loaded and clamped to the longitudinal member from the top permitting easy access and adjustment and may clamp at the same location along the rod as a vertebral fixation element. The transverse connector comprises an elongate body and an engagement portion on each opposing end of the elongate body. The engagement portion includes downward legs each with a surface to engage the longitudinal member. The downward legs are displaced from each other to define a space therebetween. The engagement portion includes an upper surface defining an opening therethrough. The opening intersects the space defined between the downward legs. Together, the space and opening are configured to receive the clamp assembly carried on the longitudinal member. Another object of the invention, is to provide an improved system including the transverse connector. Another object of the invention is to provide a transverse connector that clamps to the longitudinal member at a variable angle. Another object of the invention is to provide a separate engagement portion which can be used with existing transverse connectors to permit clamping at the same site as vertebral fixation elements. Another object of the invention is to provide a way to adjust the length of the elongate body of the transverse connector.

摘要： A lateral connector assembly for connecting a bone engaging fastener to an elongated member, such as a spinal rod includes a lateral connector having an elongated opening for receiving a portion of the bone engaging fastener therethrough. The lateral connector includes a plate portion and an integral yoke portion, which yoke portion is attached to the elongated member by way of a clamp. The lateral connector assembly can include variable angle means between the clamp and the yoke portion of the lateral connector that permits rotation of the lateral connector about an axis projecting outward from the spinal rod. The plate portion and the yoke portion of the lateral connector are oriented at non-perpendicular angles, preferably an angle greater than 100 degrees. In a further embodiment the plate portion of the lateral connector is curved so that as the bone engaging fastener slides along the elongated opening, it assumes variable angular orientations relative to the lateral connector assembly and the elongated rod.

摘要： A positionable clip is provided that is engageable on a spinal rod to capture a rod-borne component in a variable position on the rod. In one embodiment, the positionable clip includes a pair of clamping members, each including a pair of opposed arms configured for engaging the rod therebetween. A biasing hinge biases the arms together to grip the rod with sufficient force to maintain the position of the clip on the rod during manipulation of the rod. A bar connects the two clamping members to define a receiving space to receive a component that is disposed on the spinal rod. In one aspect, the bar includes a pressure surface such that a force applied to the pressure surface will cause the arms of the clamping members to displace apart to disengage from the spinal rod. The clip is configured so that this force can be applied by the component captured by the positional clip as the component is itself tightened onto the spinal rod.

摘要： This invention relates to a porous bone implant (10, 110, and 210), a method of manufacturing the implant and a method of orthopedic treatment. The mesh implant can be manufactured using extrusion techniques and a variety of cutting and machining processes to provide the implant with the desired structural features and in the required dimensions to be matingly received within the bone defect or cavity. The implant can be used to strengthen bone structures and support bone tissue adjacent to a defect of cavity. Thus, the implant can be used to provide improved treatment of patients having bone defects or diseases with decreased postoperative pain and a shorter recovery time.

摘要： A laparoscopic surgical technique is provided for preparing a site for implantation of a fusion device or implant. In accordance with one embodiment of the technique, a laparoscope is provided having an outer sleeve with distraction fingers at one end to distract the disc space. The laparoscope includes a laparoscopic port at its opposite end through which instruments and implants are inserted. The laparoscope provides a sealed working channel to the disc space, through which the disc space is distracted, the vertebral endplates and surrounding disc is reamed, and the fusion device inserted. The laparoscope is alternately engaged within bilateral locations in the disc space for insertion of a pair of fusion implants. A switching sleeve extends through the laparoscope to protect the tissue at the surgical site as the laparoscope is moved between the bilateral fusion locations.

摘要： A template assembly is provided for marking locations on the disc annulus for the implantation of an interbody fusion device or the introduction of a working instrument. The template assembly includes a tubular body sized for percutaneous introduction into a patient and advancement to an affected intervertebral disc. An elongated shaft slidably extends through the tubular body and is threadedly engaged to the tubular body at its proximal end so that rotation of the shaft relative to the tubular body advances the shaft through the body. A guide foot is pivotably connected to the distal end of the tubular body to be pivoted from a first position aligned with the tubular body to a second deployed position oriented substantially perpendicular to the tubular body. The guide body is pivoted from the first position to the second position by advancement of the elongated shaft through the tubular body. The guide body in one embodiment defines a bore through which the working tip of an electrocautery instrument extends to mark the disc annulus. In another embodiment, the guide body itself defines an electrocautery projection. The template assembly can be anchored to the affected disc by a guide wire extending through the tubular body and about which the template assembly can be rotated to make an additional mark on the annulus at a predetermined distance from the first mark.

摘要： An interbody fusion device in one embodiment includes a tapered body defining a hollow interior or chamber for receiving bone graft or bone substitute material. The body defines exterior threads which are interrupted over portions of the outer surface of the device. The fusion device includes truncated side walls so that on end view the body takes on a cylindrical form. In another embodiment, the tapered body is solid and formed of a porous biocompatible material having sufficient structural integrity to maintain the intradiscal space and normal curvature. The material is preferably a porous tantalum composite having fully interconnected pores to facilitate complete bone tissue ingrowth into the implant. In further embodiments, the fusion devices are provided with osteogenic material to facilitate bone ingrowth. A cap is also provided to block the opening of hollow fusion devices. The cap includes an occlusion body and an elongated anchor. In some embodiments the anchor includes a lip which is engageable to openings in the body wall.
