摘要:
A method of implanting a spinal prosthesis comprises inserting a first member between superior and inferior spinous processes associated with respective superior and inferior vertebrae. The superior and inferior vertebrae are separated by an intermediate vertebra. The method further includes inserting a second member through a channel in the first member. After the second member is inserted, the method requires removing the second member from the channel and inserting a third member through the channel. The third member has a different stiffness than the second member. Finally, the method requires anchoring the third member to the intermediate vertebra, while the third member is inserted through the channel. The third member is anchored at first and second locations disposed on respective first and second lateral sides of the intermediate vertebra.
摘要:
A prosthetic device and method of inserting same between adjacent vertebrae, according to which a first member of a relatively flexible material is adapted to extend between the vertebrae; and at least one second member of a relatively stiff material is supported by the first member.

An implant assembly for stabilizing a spinal motion segment includes a spacer which is at least partially flexible and positionable in an interspinous spacer between adjacent spinous processes. The spacer member includes upper and lower surfaces structured to receive a respective adjacent one of the upper and lower spinous processes of the spinal motion segment and a body having distinctive first and second sections with differing flexibility to modify the manner of movement at the spinal motion segment.

Methods and systems for performing a surgical procedure using implantable sensors are disclosed. The method includes providing one or more implantable sensors, each sensor configured for implantation adjacent to an anatomical feature of a patient; imaging the patient to determine the relative positions of the one or more implantable sensors relative to the anatomical features of the patient; inserting an implant adjacent to at least one of the anatomical features; and tracking the position of the implant relative to the at least one anatomical feature during the inserting of the implant using the implantable sensors.

An implant is disclosed and can include a body and a plurality of pellets disposed within the body. The implant can be moved between an unmolded, relaxed configuration wherein the body is not conformed to a bone and a molded, relaxed configuration wherein the body is at least partially conformed to the bone.
摘要:
One embodiment of the present application includes a spinal disk prosthesis with one end portion to form a load transmitting relationship with one vertebra of a patient's spine and another end portion to form a load transmitting relationship with another vertebra of the patient's spine. A tube connects the end portions together and a damping material is positioned inside the tube. The end portions each include a magnet to generate a corresponding magnetic field. These magnetic fields are oriented to provide a repulsive force between the end portions to provide a magnetic bearing.
