Asymmetric rib profiles anchor intervertebral prostheses into vertebral bodies while minimizing bone damage during insertion.
Curved articulation surfaces increase intervertebral spacing as a smooth function of angular displacement, preventing end-motion impact and tissue degeneration.
An adjustable annular repair device seals damaged intervertebral discs, preventing nucleus pulposus leakage and preserving disc height.
A compressible prosthetic intervertebral disc expands in situ to restore natural spinal biomechanics.
Helical shock absorber resolves reliability complexity trade-off, mimicking natural spinal motion through elastic deformation.
Modular anatomic adaptation elements on a universal base prosthesis reduce manufacturing costs and stock levels while maintaining mobility.
An orthopedic implant system uses a plate, staple, and coupling device to stabilize vertebral bodies.
Nested cammed sleeve and rib mechanism secures cartilage implant during insertion, resolving retention control issues in bone repair procedures.
A multi-piece artificial disc prosthesis uses a fluid-filled balloon to maintain intervertebral space and absorb shocks while resisting hyperextension.
Segmented radial teeth resist multi-directional expulsion forces while tapered edges distract vertebral members during insertion.
Porous vertebral body replacement devices prevent bone subsidence by enabling osteointegration within the implant structure.
An intermediate polymeric ring absorbs compression stress during press-fitting of ceramic inlays, preventing damage while maintaining a secure connection.
Pivoting compression members press prosthetic endplates into vertebral anatomy to prevent implant migration.
A polymeric intervertebral implant uses a semi-spherical orientation protrusion to inhibit rotation within the disc space.
Adjustable coupling elements adapt spacing to engage diverse intervertebral implants.
Parametrized porous Ti6Al4V fusion cage reduces stress concentration by matching bone elastic modulus.
An expandable elliptical mesh cage integrates with a fixation plate to fill bone gaps without shortening the bone.
Asymmetric vertebral implant curvatures match endplate morphology, eliminating bone preparation and preserving vertebral body strength.
