A61B 17/70

US Classification:

606279, 606246, 623 1716

Abstract:

Misaligned bones on opposite sides of a joint are aligned using a first rigid extension securable to one of the misaligned bones using a particular surgical approach, and a second rigid extension having a contacting surface positionable in contact with the other the two misaligned bones from the same surgical approach. The first and second rigid extensions are moved with respect to each other using a lever, whereby a pulling force is exerted on one of the bones, and a pushing force on the other, thereby aligning the first and second misaligned bones.

International Classification:

A61B 17/70

US Classification:

606279

Abstract:

The present invention provides a bone screw which can be used for fixation and/or fastening of prosthetic devices or instruments to bone tissue whose structure or dimensions differ from one region to another. In particular, the present invention provides a bone screw which is designed to optimize purchase in both the cancellous and cortical regions of a vertebral body. In an exemplary embodiment, the bone screw has a distal portion and a proximal portion in which the diameter of the thread on the proximal portion of the screw is greater than the diameter of the thread on the distal portion of the screw.

International Classification:

A61B 17/70

US Classification:

606249

Abstract:

A resilient core is positioned between bony projections which are offset from a principal load bearing region of a spinal joint. Shaped projections extend from the core, and engage the bony projections by conforming to anatomical landmarks, and may be fastened to the bony projections. During flexion of the joint, the core absorbs some of the force of compression, and limits an extent to which the joint may compress. If the shaped projections are connected to the bony projections, extension of the joint is inhibited by the projections and the core, limiting the extent to which the joint may be distracted. In this manner, healing is fostered, and a weakened or damaged joint is protected from excessive movement.

International Classification:

A61F 2/44
A61F 2/46

Abstract:

The present application generally relates to orthopedic systems, and in particular, to systems including independent plates and spacers. A plating system can include a spacer and a plate that is independent from the spacer. A number of locking mechanisms can be provided to secure the plate to the spacer. In some cases, the spacer includes a pair of notches that extend on an outer surface of the spacer. The plate can include a pair of lateral extensions that can engage the notches to secure the plate to the spacer. In other cases, the spacer includes an opening including a pair of inlets. The plate can include an enclosed posterior extension that can be received in the pair of inlets to secure the plate to the spacer.

International Classification:

A61F 2/44
A61F 2/46

Abstract:

A method of implanting an intervertebral spacer may include positioning the intervertebral spacer within an intervertebral space defined by adjacent vertebral bodies. The intervertebral spacer may include a plurality of bores, and each of the plurality of bores may be configured to receive either a linear fastening element or a curvilinear fastening element. The method also may include selecting a first fastening element from a group including linear fastening elements and curvilinear fastening elements, and inserting the first fastening element into a first bore of the plurality of bores such that the first fastening element is inserted into one of the adjacent vertebral bodies to secure the intervertebral spacer within the intervertebral space.
