Inter-vertebral disc motion devices and methods of use

摘要

A mobile device is adapted to at least partially replace the motion characteristics of a natural inter-vertebral disc positioned in a disc space. In an embodiment, a receptacle is coupled to the bearing surface. The receptacle is adapted to accept an implantable material without the removal of the bearing surface, wherein the implantable material contacts the abutment surface of each of the vertebral bodies adjacent to the disc space and leads to fusion and immobilization of two vertebral bodies adjacent the disc space.

主权项

1. A method for the correction of vertebral scoliosis without bone fusion using a minimally invasive surgical technique, comprising:
laterally approaching a side of a convexity of a deformity in the spine, wherein the side of the convexity is a side of the vertebral midline in which the vertical distance between the pedicle portion of each vertebral body of the spine is greatest; and placing a mobile orthopedic prosthesis into a disc space via the lateral approach, wherein the orthopedic prosthesis contains at least one bearing surface that is adapted to at least partially replace a natural inter-vertebral disc, wherein the length of the prosthesis in the coronal plane is less than that of the inter-vertebral disc.
