A vertebral insert may include a first linkage, a second linkage, and a third linkage. The first, second, and third linkages may at least partially defining a cavity. The insert may be movable between a collapsed configuration and an expanded configuration, and the movement of the first and second linkages with respect to one another may be configured to reciprocally move the insert between the collapsed and expanded configurations.

A surgical pelvic drill for operating hip osteoarthritis adapted to create a hole in the pelvic bone of a human patient is provided. The pelvic drill is adapted to create a through-going hole placed in the acetabulum area from the abdominal side of the pelvic bone of the human patient. The pelvic drill comprises: a driving member, a bone contacting organ in connection with said driving member, an operating device adapted to operate said driving member. The bone contacting organ is adapted to create a hole in the acetabulum area starting from the abdominal side of the pelvic bone through repetitive or continuous movement. A surgical and a laparoscopic/arthroscopic method of using said pelvic drill is further provided.

An intervertebral fusion cage that is adapted to contain an inserter within its inner volume during insertion of the cage.

An intervertebral implant is provided. The intervertebral implant comprises a first component comprising an outer tissue engaging surface and an inner surface. A second component is connected to the first component, and is relatively moveable therefrom. The second component comprises an outer tissue engaging surface and an inner surface. The second component includes an actuator. A third component is disposed for engagement and is movable relative to the first and second components. The third component comprises at least a first ramp and a second ramp axially spaced apart from the first ramp. The actuator is engageable with the third component to effect axial translation of the wedge such that the ramps engage the inner surface of at least one of the first component and the second component to move the components between a first, collapsed configuration and a second, expanded configuration. Methods of use are disclosed.

The present invention relates generally to a prosthetic spinal disc for replacing a damaged disc between two vertebrae of a spine. The present invention also relates to a method for implanting a prosthetic spinal disc via anterior or anterior lateral implantation. Other surgical approaches for implanting the prosthetic disc may also be used.

An implant device is provided that is configured for implantation at multiple locations between adjacent vertebrae. The implant device comprises an implant body, a first portion of the implant body, and a second portion of the implant body adjustably interconnected with the first portion. The implant body has a compact orientation and an extended orientation to allow the implant body to be shifted from one orientation to the other orientation for being positioned in any one of areas between the spinous processes of the adjacent vertebrae, between laminar regions of the adjacent vertebrae, spanning an opening in the annulus between the adjacent vertebrae, and in the intervertebral space between the adjacent vertebrae.

A prosthetic device for replacing at least part of one vertebral body, the prosthetic device being expandable from a fully collapsed state to a fully expanded state and comprising an upper endplate, a lower endplate and an expandable support structure extending between the two endplates, said expandable support structure being configured to displace the two endplates relative to one another along a longitudinal axis of the prosthetic device and to hold the two endplates at a minimum axial distance that corresponds to the height of at least one intervertebral disc and half a vertebral body, wherein the expandable support structure includes an anterior post and a posterior post, wherein the length (L1/L2) of each post is individually adjustable and is lockable independently from one another to hold the two endplates with an inclination of 0 to 40 relative to each other.

Prostheses and methods are described for stabilizing dysfunctional sacroiliac (SI) joints. The prostheses are sized and configured to be press-fit into surgically created pilot SI joint openings in dysfunctional SI joint structures. The prostheses have a pontoon shape with opposed elongated partially cylindrical sections connected by a bridge section. The bridge section can have various shapes, such as an offset, arched structure, to accommodate the delivery and/or positioning of a primary or supplemental support member or device between the first and second elongated sections, such as a sacral-alar iliac (S2AI) screw or surgical dowel member.

Methods for altering the natural history of degenerative disc disease and osteoarthritis of the spine are proposed. The methods focus on the prevention, or delayed onset or progression of, subchondral defects such as bone marrow edema or bone marrow lesion, and subchondral treatment to prevent the progression of osteoarthritis or degenerative disc disease in the spine and thereby treat pain.
