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.

摘要:
Orthopedic implants include a device that is non-rigid, i.e., flexible and/or malleable, in a first form for insertion into a desired in vivo site, and then transformable into a rigid, or hardened, form for providing a load-bearing function or providing other structural and/or mechanical function after implant. The device includes a biocompatible sheath and a curable material sealed within the sheath. The curable material is provided in a first form that provides flexibility to the device and is structured to rigidize in a second form after application of a quantity of an initiating energy to the material. Related methods and kits are also provided.

摘要:
Apparatus and methods include implants insertable into the body of a patient for posterior lateral fusion of one or more vertebral levels. The implant can be osteoinductive and/or osteoconductive to facilitate or initiate the fusion between two or more bony portions of the spinal column. The fusion implant can be used in isolation or in conjunction with a posterior stabilization construct.
摘要:
A spinal rod includes an elongated tubular member that is inflatable from a first insertion profile to a second enlarged profile. An expandable tubular reinforcement sleeve is concentrically positioned adjacent to the balloon. The balloon may be bonded to the sleeve. The spinal rod may also have longitudinal reinforcement members. A joining member may join two or more of the longitudinal reinforcing members at a discrete point along each. The spinal rod may further include end portions on either side of an inflatable portion.
