Transforaminal prosthetic spinal disc apparatus

摘要

An intervertebral prosthetic implant having a first endplate having a first surface configured to substantially engage with a first vertebral body and a second surface having an extension with a concave contact surface, the concave contact surface being spaced apart from the second surface. A second endplate is provided with a first surface configured to substantially engage with a second vertebral body and a second surface comprising a convex contact surface, and the second endplate having a securing element positioned along and above the second surface defining a first and second window on opposing sides of the second surface. The securing element extends along the width and length of the lower endplate and configured with an access hole. An extension portion extends from the first surface of the first endplate through the access hole of the securing element and contacts the second surface of the second endplate.

主权项

1. An implant for positioning between adjacent vertebral bodies comprising:
a first endplate having a first surface configured to substantially engage a first vertebral body, the first endplate including a first keel; and a second endplate having a second surface configured to substantially engage with a second vertebral body, the second endplate including a second keel, wherein the second endplate includes a first window and an opposing second window, wherein a portion of the first endplate directly contacts a surface of the second endplate and is retained within the first and second windows of the second endplate.
