    摘要: A method for treating a vertebral bone comprises providing a gaseous substance and providing a flowable and settable bone filling material. The method further comprises introducing the gaseous substance into the bone filling material to form a porous bone augmentation material and inserting a material delivery device into the vertebral bone. The method further comprises injecting the porous bone augmentation material from the material delivery device and into the vertebral bone.

    摘要: A bone fastener includes a fixation portion configured to interface with boney tissue, a connection portion having a longitudinal axis and being configured to interface with an elongated support structure, and a flexible portion disposed between the fixation portion and the connection portion. The flexible portion is configured to permit flexure of the connection portion relative to the fixation portion. The flexible portion has a first set of opposed facing surfaces that mechanically limit the range of flexure in a first direction. It has a second set of opposed facing surfaces that mechanically limit the range of flexure in a second direction. The opposed facing surfaces are substantially transverse to the longitudinal axis.

    摘要: This invention relates to orthopedic implants and to methods of treating bone defects. More specifically, but not exclusively, the present invention is directed to non-metallic implants and to methods for intra-operative assembly and fixation of orthopedic implants to facilitate medical treatment. The non-metallic implant assembly can be secured to underlying tissue by a fastener, such as a bone screw, that is capable of swelling on contact with fluid in the underlying tissue. Alternatively, the non-metallic implant assembly can be assembled intra-operatively using a fastener that is adhesively bonded to a bone plate or the bone plate can be deformed using heat, force, or solvents to inhibit withdrawal of the fastener. In preferred embodiments, both the fastener and the bone plate are formed of biodegradable material.
