摘要:
A system for the treatment of a spine generally comprises an implant and an attachment device for securing the implant to a portion of a patient's bone. A first portion of the attachment device is sized for insertion into a hole in the bone, and a second portion of the attachment device is configured to be received in an opening of the implant. The first portion comprises a biocompatible material defined by a network of interconnected pores configured promote bone growth into the first portion.

A device for fixing a rod to an osseous structure. The device is configured to receive the rod with the main axis oriented in a first direction. The device includes a main body, a first fastening member directly connected to the main body and accessible from an outer surface of the main body for fastening the rod to the main body, and a second fastening member, also directly connected to the main body, offset with respect to the first fastening member in said first direction, and separately accessible from an outer surface of the main body for fastening to the main body. A flexible elongate member is provided to attach the main body to the osseous structure. The first and second fastening members are arranged so that the flexible elongate member can be fastened adjacent to the rod.

A spinal stabilization system according to the present invention, comprises: an anchor member configured to be secured to a vertebra within a patient's body including: a pedicle screw body; a housing having internal threads ; and a set screw;
a flexible element; a rigid element securable to the anchor member and having an end portion with an end surface, an axial bore extending from the end surface, an outer surface, and an opening on the outer surface extending into the axial bore, the axial bore receiving a portion of the flexible element therein; and a fastener extending through the opening in the outer surface of the rigid element to retain the flexible element in the axial bore.
摘要:
A system for reduction of vertebral bodies (or vertebrae) in various embodiments includes a reducer, and extender, and a hollow tube. The reducer couples to the extender, which in turn couples to an elongated member, such as a rod, and to a bone fastener assembly. The reducer allows reduction of the vertebral body incrementally, and by a desired amount. The reducer may include or may be used in conjunction with a holding device or holder in order to hold or keep the amount of reduction constant or steady once the desired amount of reduction has been obtained. The reducer may use one of several embodiments, including embodiments that use threaded assemblies or members, inclining members or wedges, offset cams, scissor jacks, and/or levers.
摘要:
A vertebral fixing system having a flexible elongated member, a connecting part, and an anchor, where the anchor may engage a bone structure (e.g., a vertebra) through an opening of the connecting part and the flexible elongated member may connect to the connecting part. In some cases, the vertebral fixing system may include a tightening part configured to apply a tension to the elongated member and/or secure the elongated member with respect to the connecting part. The vertebral fixing system may be configured to receive a rod and may be capable of connecting thereto. The connecting part may have a plurality of connecting members, where at least one of the connecting members includes an opening for receiving the anchor and at least one of the connecting members connects to the elongated member.
