摘要: A prosthetic disk having ball and socket members made of a material having expected durability to function properly for 40 years in a typical lumbar spine. The disk is shaped to provide movement in 6 degrees of freedom mimicking normal intervertebral movement, except compression. The arthroplasty device is non-compressible to maintain distraction of the facet joints posteriorly. Base plates with tabs can be fastened to the ball and socket members to ensure short-term and long-term fixation, although it is expected not to be necessary.

摘要: A disk arthroplasty device (310) is provided for replacement of a spinal disk. The device is implantable into a resected disk space and is formed with ball (346) and socket (326) members and shaped to provide lateral bending and backward extension of up to about 5.degree. and forward flexion of up to about 15.degree.. Four embodiments (10), (110), (210) and (310) permit up to about 5.degree. axial rotation and a fifth embodiment (410) permits unrestricted axial rotation. Metal insert cups (70) and (170) are provided for attaching to the device surfaces and are convexly shaped along one axis to conform to the natural contours of the top and bottom vertebra surfaces. The metal insert cups (70) and (170) provide tensile support to the structure and provide for the attachment of additional structures for retaining the device in position after implantation into a disk space.

摘要: A spinal fixation device and method for the stabilization of the spine after surgical procedures such as those related to degenerative disc diseases are described. The device comprises a spacer, which is placed between adjacent vertebrae when installed and a locking mechanism attached to the spacer. The locking mechanism attaches the device to the spinous processes of adjacent vertebrae of the spine in a manner which is non-invasive with respect to the vertebrae to which it is attached.
