Provided is a cage for spinal surgery, in which an elastic structure having elasticity and a porous structure are combined with each other to elastically support the vertebra and increase a bone fusion rate.

The cage for the spinal surgery includes an elastic structure having a plurality of leaf springs provided, respectively, on both sides of a frame, one end of which protrudes, and a porous structure coupled to the elastic structure while being elastically supported by the elastic structure, and disposed in space between neighboring vertebrae, with a plurality of bone fusion holes for bone growth being formed on a surface of the porous structure.

A system and method for sharing and absorbing energy between body parts. In one particular aspect, the system facilitates absorbing energy between members forming a joint such as between articulating bones.

A device and methods for intervertebral spinal fusion of adjacent intervertebral bodies. An intervertebral spacer is positioned within a narrow disc space between adjacent intervertebral bodies of a patient. The spacer is arranged with upper and lower guides. The guides are adapted to simultaneously guide the deployment of upper and lower anchors of an anchoring device into their respective intervertebral bodies. The spacer is also adapted to lock the upper and lower anchors to the spacer in the deployed position.

An interbody support system that includes a support and a containment body, the containment body having a fixed height or an adjustable height, and the support having a support column, which may have a fixed height or an adjustable height, an inferior plate at one end of the support column and a superior plate at the other end of the support column.

A system for implanting an inter-body device between adjacent vertebrae comprises an inter-body device having a plurality of cans secured to a flexible bridge and having a relief portion therebetween. An inserter tube and complementary bullnoses are advantageously secured to the vertebrae by an extension arm for securing the assembly precisely in place. A plurality of articulating trial implants are provided to test fit a disc space for the proper sized inter-body device.

A process for introducing a stabilizing element into a vertebral column, in which the stabilizing element is introduced in such a manner that the stabilizing element connects two adjacent vertebral bodies to one another.

Osteogenesis scaffold such as for spinal fusion or an intermedullary nail includes a number of arcuate struts. The scaffold may have a functional modulus of elasticity that is a result of the modulus of the material of the struts together with the architecture of the struts, and may be within the range of 5 GPa and 75 GPa. An anisotropy of a physical property such as stiffness, compressive strength or elastic modulus corresponds to the same physical property of native bone in the vicinity of the intended implantation site.

An orthopedic system that includes a first augment that has a body and a first biasing member projecting from the body. The body has a first and second face. The first and second faces are separated by a thickness of the augment. The system also includes a femoral prosthesis that has an articular side that defines condylar portions and a bone-facing side opposite the articular side. The bone facing side defines an augment opening that is sized to receive the augment therein. When the first augment is received within the augment opening, the first biasing member presses directly against the femoral prosthesis so as to retain the body within the augment opening.

A glenoid component for securement to a glenoid surface of a scapula comprises a body portion having a first surface adapted to contact the glenoid surface of a scapula and a second surface configured to receive the head portion of a humerus. The glenoid component further includes an anchor peg for penetrating the glenoid surface of the scapula so as to secure the body portion to the glenoid surface of the scapula. The anchor peg includes a cylindrical shaft extending from the first surface of the body portion and a fin secured to and extending outwardly from the cylindrical shaft. The glenoid component further includes a feature that prevents rotation of the glenoid component.

A system for implanting an inter-body device between adjacent vertebrae comprises an inter-body device having a plurality of cans secured to a flexible bridge and having a relief portion therebetween. An inserter tube and complementary bullnoses are advantageously secured to the vertebrae by an extension arm for securing the assembly precisely in place. A plurality of articulating trial implants are provided to test fit a disc space for the proper sized inter-body device.
