A spinal implant including porous and solid portions is disclosed. The implant includes porous portions on upper and lower surfaces and in an interior thereof. Methods of manufacturing and implanting such implants are also disclosed.

Spinal implant with porous and solid surfaces

A spinal interbody device (IBD) includes a solid wall that at least partially defines a boundary of the IBD and a porous body connected to the solid wall. The porous body includes a plurality of sections that form at least a portion of both a superior and inferior bone interface side of the IBD. Each section of the porous body has a different porosity than an adjacent section such that the porosities increase toward a center of the IBD.

Interbody implants and optimization features thereof

Implants including non-resorbable frameworks and resorbable components, as well as methods of use thereof are disclosed. The embodiments include different combinations of a non-resorbable framework (in some case structural and in other cases non-structural), and a resorbable component embedded within and/or around the framework (again, in some cases structural and in other cases non-structural). The disclosed implants provide an efficient means of providing structural support for the vertebral bodies post-implantation, as well as encouraging resorption of the implant and fusion of the associated vertebral bodies without negative side effects and/or failure, such as subsidence of the implant or cracking/fracturing of a portion of the implant when implanted.

Partially resorbable implants and methods

Disclosed herein is a spinal implant with a solid frame and a porous inner layer. The implant may have a cavity defined by the porous inner layer. The solid frame may have one or more ribs extending from a medial wall to a lateral wall. The thickness of the porous layer may vary relative the thickness of the solid frame at various locations. An inserter to place a spinal implant and a method to perform same are also disclosed.

Spinal implants

A bone fastener includes a head, and a screw portion extends from the head. The screw portion includes a shaft and a thread extending along and about the shaft. The thread has a height extending from a root to a tip thereof. The thread also has first and second portions disposed between the root and the tip. The second portion has a porous structure configured to promote bone ingrowth and has a porosity greater than that of the first portion.

Orthopedic screw and porous structures thereof

A prosthesis for spinal surgery includes a spacer adapted to be secured into the bone and attached to one of a plurality of configuration plates. The configuration plates are interchangeable and each one is configured to utilize a different combination of bone screws, anchors or both. The prosthesis may further include a retaining mechanism to prevent bone screws and/or anchors from backing out.

Spinal implant system

A spinal fusion implant including a body and a jacket is disclosed. The jacket includes at least two radiopaque markers extending therefrom for use in determining the position of the implant after placement between intervertebral bodies. Methods of implanting and evaluating positioning of the implant are also disclosed.
