摘要： Spine stabilization devices, systems and methods are provided in which a single resilient member or spring is disposed on an elongate element that spans two attachment members attached to different spinal vertebrae. The elongate element passes through at least one of the two attachment members, permitting relative motion therebetween, and terminates in a stop or abutment. A second resilient member is disposed on the elongate element on an opposite side of the sliding attachment member, e.g., in an overhanging orientation. The two resilient members are capable of applying mutually opposing urging forces, and a compressive preload can be applied to one or both of the resilient members.

摘要： A prosthetic nucleus replacement embodiment of the present invention comprises a rounded shaped ceramic domed body with a receptacle in its bottom side. A keeled base of biocompatible metal is press-fit into the receptacle at any relative angle to complete a two-piece assembly. A keel part of the base especially is finished in porous coated metal and shaped to promote natural in-growth of bone from the inferior vertebrae.

摘要： A system for surgically coupling the spinous processes includes a first plate, a second plate, a pair of semi-rigid guide members, and a coupler. The first plate engages with a first lateral side of the spinous processes. The pair of semi-rigid guide members attaches to the first plate for inserting the first plate between the spinous processes. The second plate includes a pair of apertures that slide over the pair of semi-rigid guide members engage a second lateral side of the spinous processes. The coupler couples the first plate and the second plate together.

摘要： A dynamic spine stabilization device is provided that includes at least one force imparting member, e.g., a spring. The force imparting member is adapted to deliver a force of between about 150 lb/inch and 450 lbs/inch, and restrict the relative travel distance between said first and second pedicles to a distance of between about 1.5 mm and 5 mm. The spinal stabilization devices also have a minimal impact on the location of the center of rotation for the spinal segment being treated. By providing resistance in the noted range and restricting the travel distance to the noted range, it has been found that the stabilization device provides a desired level of stabilization, as reflected by range of motion values that closely approximate pre-injury range of motion levels. In addition, the resistance levels are not so high as to alter the location of the center of rotation of the treated spinal segment from its normal anatomical location to levels previously obtained, thereby permitting substantially unimpeded angular motion despite the posterior presence of a stabilization device.
