7 results about "Disc height" patented technology

The embodiments provide various interbody fusion spacers, or cages, for insertion between adjacent vertebrae. The cages may have integrated ratchet assemblies that allow the cage to change size and angle as needed, with little effort. The cages may have a first, insertion configuration characterized by a reduced size to facilitate insertion through a narrow access passage and into the intervertebral space. The cages may be inserted in a first, reduced size and then expanded to a second, larger size once implanted. In their second configuration, the cages are able to maintain the proper disc height and stabilize the spine by restoring sagittal balance and alignment. Additionally, the intervertebral cages are configured to be able to adjust the angle of lordosis, and can accommodate larger lordotic angles in their second, expanded configuration. Further, these cages may promote fusion to further enhance spine stability by immobilizing the adjacent vertebral bodies.

Described herein is a technique (e.g., apparatus and method) to improve consistency of lumbar lordosis (LL) and disc height index (DHI) measurements. In at least one embodiment, one or more processors are to measure lumber spine based, at least in part, on cross-sectional area and optical center of mass of segmented intervertebral discs (IVDs).

The embodiments provide various interbody fusion spacers, or cages, for insertion between adjacent vertebrae. The cages may contain an articulating mechanism to allow expansion and angular adjustment, and enable upper and lower plate components to glide smoothly relative to one another. The cages may have a first, insertion configuration characterized by a reduced size at each of their insertion ends to facilitate insertion through a narrow access passage and into the intervertebral space. In their second, expanded configuration, the cages are able to maintain the proper disc height and stabilize the spine by restoring sagittal balance and alignment. The intervertebral cages are able to adjust the angle of lordosis, and can accommodate larger lodortic angles in their second, expanded configuration. Further, these cages may promote fusion to further enhance spine stability by immobilizing the adjacent vertebral bodies.

The utility model discloses a disc height adjusting structure of a disc buckle type supporting frame. The disc height adjusting structure comprises a disc, a movable adjusting piece, an anti-sliding-down auxiliary piece and a vertical rod. The disc is formed by butting two semicircular discs; the movable adjusting part comprises a movable sleeve, a fixed lead screw, an opening-closing-opening rotating shaft and a locking assembly, the movable sleeve is composed of two semicircular sleeves, one ends of the two semicircular sleeves are connected through the opening-closing-opening rotating shaft, the other ends of the two semicircular sleeves are correspondingly provided with the locking assembly, and the two semicircular sleeves are provided with corresponding radial threaded holes; the radial threaded holes of the semicircular sleeves are in threaded connection with rotary fixing lead screws, the upper ends of the two semicircular sleeves are correspondingly welded to the two semicircular discs, and the lower ends of the two semicircular sleeves are provided with pressing openings matched with the anti-sliding-down auxiliary parts. The anti-gliding auxiliary part comprises two semicircular elastic parts which are in butt joint, magnetic stickers are pasted and embedded in the inner walls of the semicircular elastic parts, and the anti-gliding auxiliary part is fixed to the vertical rod through the magnetic stickers. The height of the disc can be effectively adjusted, and the site construction requirement is met.

A bi-directional fixating transvertebral (BDFT) screw / cage apparatus including an intervertebral cage for maintaining disc height, and a method of inserting the same is provided. The intervertebral cage includes a first internal screw guide and a second internal screw guide, a first screw member and a second screw member, and a central screw locking lever coupled to the intervertebral cage, wherein the central screw locking lever prevents the first screw member and the second screw from pulling-out of the first internal screw guide and the second internal screw guide. The central screw locking lever includes a rotatable handle and stem portion, or a screw locking horizontal bracket. A pliers device for inserting and removing the bi-directional fixating transvertebral (BDFT) screw / cage apparatus, a posterior cervical and lumbar facet joint staple, and a staple gun for a posterior cervical and lumbar facet joint staple also are provided.

A method of treating lower back pain in a subject in need thereof, the method comprising administering to the subject a composition comprising mesenchymal lineage precursor or stem cells (MLPSCs), wherein the lower back pain is associated with an intervertebral disc that has a disc height that is not substantially reduced compared to that of an adjacent healthy disc in the subject. 20 26 20 47 17 18 J un 2 02 6 A B S T R A C T 2 0 2 6 2 0 4 7 1 7 1 8 J u n 2 0 2 6
