Device for Stabilizing a Vertebral Joint and Method for Anterior Insertion Thereof

摘要

A prosthetic device can be used as a prosthesis following a discectomy or a corpectomy. The prosthetic device includes two endplates with staggered motion limiting members. The device can be configured to allow six degrees of motion when comparing one endplate relative to the other. The endplates can be configured to fix the joint by changing the body held within the device and by adding a locking plate and fasteners. A method teaches how to insert a device to an intervertebral space via an anterior incision.

主权项

1. A device for stabilizing a first vertebra relative to a second vertebra, the device comprising:
a superior endplate having an inferior surface and a motion limiting member, said motion limiting member extending downward below said inferior surface; an inferior endplate having a superior surface and a motion limiting member, said motion limiting member extending upward above said superior surface; a compressible and flexible body having a superior surface and an inferior surface, said superior surface of said body facing said inferior surface of said superior endplate, said inferior surface of said body facing said superior surface of said inferior endplate, said body being held in contact with and laterally between said superior endplate and said inferior endplate by said motion limiting members; and a locking plate having a superior screw anchoring member configured to connect to a first vertebra and an inferior screw anchoring member configured to connect to a second vertebra, said locking plate overlying said superior endplate and said inferior endplate.
