The invention relates to an implant for replacing bone or cartilage material, which is constituted by a plurality of elements (B, B1, B2, B3, B4) produced from a non-metallic, linearly elastic material, an element (B, B1, B2, B3, B4) being connected to adjacent elements (B, B1, B2, B3, B4) by a viscoelastic polymer material such that gaps (L) remain between the adjacent elements (B, B1, B2, B3, B4) and that the adjacent elements (B, B1, B2, B3, B4) can move relative to one another.

Surgical instrumentation may be used to insert a spinal implant into a vertebral space while in a contracted condition and then deploy the spinal implant into an expanded condition.

A system for performing a fusion procedure on a sacroiliac joint defined between a sacrum and an ilium. The system may include a working cannula including a proximal end, a distal end, a tubular body extending between the proximal and distal ends, a cannula passageway defined within the tubular body and having a cannula axis extending there through, a pair of prongs coupled to the tubular body and extending distally there from, an anchor arm engagement structure coupled to the tubular body, and a pin guide coupled to the tubular body and defining a pin passageway having a guidance axis there through that is generally parallel with the cannula axis.

An implant includes a central wall extending from a first side of a peripheral frame portion to a second side of the peripheral frame portion, and a first helical bone contacting member attached at the central wall and disposed within the superior half of the implant. The implant further includes a first support member attached at the central wall at a junction coincident with the first helical bone contacting member and extending to a central region of the implant internal to the first helical bone contacting member. In addition, the implant includes a non-helical bone contacting member extending from a portion of the first support member that is disposed internal to the first helical bone contacting member.

An intervertebral implant for implantation in an intervertebral space between vertebrae. The implant includes a body extending from an upper surface to a lower surface. The body has a front end, a rear end and a pair of spaced apart first and second side walls extending between the front and rear walls such that an internal chamber is defined within the front and rear ends and the first and second walls. The body defines an outer perimeter and an inner perimeter extending about the internal chamber. At least one of the side walls is defined by an integral porous structure which extends from the outer perimeter to the inner perimeter. The at least one of the side walls is free of vertical solid support structure between the upper and lower surface.

A system used for connecting a first implant and a second spinal implant. Among other things, the system includes a connector with a flexible member that allows the connector to be positioned a plurality of angles relative to the first implant.

Provided is a four-directional extended intervertebral fusion cage device including a front support, a rear support, and four plates having front ends engaged with the front support and rear ends engaged with the rear support, and configured to slide up in four different directions on inclined surfaces of the front support and the rear support and increase a height and a width of the cage device simultaneously, when the front support and the rear support move toward each other, facing each other.

Particular aspects provide novel devices for bone tissue engineering, comprising a metal or metal-based composite member/material comprising an interior macroporous structure in which porosity may vary from 0-90% (v), the member comprising a surface region having a surface pore size, porosity, and composition designed to encourage cell growth and adhesion thereon, to provide a device suitable for bone tissue engineering in a recipient subject. In certain aspects, the device further comprises a gradient of pore size, porosity, and material composition extending from the surface region throughout the interior of the device, wherein the gradient transition is continuous, discontinuous or seamless and the growth of cells extending from the surface region inward is promoted.

In various embodiments, an implant for interfacing with a bone structure includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue. In some embodiments, a method is provided that includes accessing an intersomatic space and inserting an implant into the intersomatic space. The implant includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue.

Systems and methods for treating musculoskeletal disorders of the spinopelvic anatomy including treating spinal deformities by spinopelvic fixation including fusion of the sacroiliac joint at the base of long spinal fusion construct cases. The system may include implants designed to be used as an adjunct to long spinal fusions to further the immobilization and stabilization of the sacroiliac joint. The implants may be designed to augment an S2AI screw and an S1 screw in order to improve durability of the foundation of the spinal construct. The implants may have a triangular cross section.
