Threaded spinal implant

TL;DR: In this article, a spine distraction implant alleviates pain associated with spinal stenosis and facet arthropathy by expanding the volume in the spine canal and/or neural foramen.

TL;DR: A guarded sleeve system for use in human spinal surgery across the height of a disc space between two adjacent vertebral bodies is described in this paper, where an outer sleeve having an opening for providing protected access to the disc space and at least portions of the adjacent vertebras.

TL;DR: In this paper, a structural configuration of interbody spinal fusion implant (100) is proposed for the maintaining and creating of the normal anatomic angular relationship of two adjacent vertebrae (V2, V3) of the spine to maintain and create spinal lordosis.

TL;DR: In this article, an apparatus for delivering a clip to close an opening through tissue includes a sheath and a carrier assembly including a clip therein that is slidable on the sheath.

TL;DR: In this paper, an intervertebral disc prosthesis is proposed to replace a natural intervein disc and to restore the normal intervertesbral spacing without complete loss of flexibility of the spinal joint.

TL;DR: In this article, the articular surface forms curvatures of different mean radius in the median section and in the frontal section, and stops are provided on the prosthesis plates and the prosthetic core.

TL;DR: The most commonly used form of the prosthesis is a curved, flat, bar-like element shaped into a spiral configuration, so that the overall appearance approximates a flat disc.

TL;DR: A collapsible plastic bladder-like prosthesis of the same external form as the nucleus pulposis of an intervertebral disc has a stem through which liquid and/or plastic is introduced to inflate the prosthesis to natural form as discussed by the authors.
