An interbody spinal implant including a body having a top surface, a bottom surface, opposing lateral sides, and opposing anterior and posterior portions. At least a portion of the top surface, the bottom surface, or both surfaces has a roughened surface topography including both micro features and nano features, without sharp teeth that risk damage to bone structures, adapted to grip bone through friction generated when the implant is placed between two vertebrae and to inhibit migration of the implant. The roughened surface topography typically further includes macro features and the macro features, micro features, and nano features overlap. Also disclosed are methods of using such implants and processes of fabricating a roughened surface topography on a surface of an implant. The process includes separate and sequential macro processing, micro processing, and nano processing steps.

A method of manufacturing a resorbable, macroporous bioactive glass scaffold comprising approximately 15-45% CaO, 30-70% SiO.sub.2, 0-25% Na.sub.2O, 0-17% P.sub.2O.sub.5, 0-10% MgO and 0-5% CaF.sub.2 by mass percent, produced by mixing with pore forming agents and specified heat treatments.

Systems and methods for providing deeper knee flexion capabilities, more physiologic load bearing and improved patellar tracking for knee prosthesis patients. Such systems and methods include (i) adding more articular surface to the antero-proximal posterior condyles of a femoral component, including methods to achieve that result, (ii) modifications to the internal geometry of the femoral component and the associated femoral bone cuts with methods of implantation, (iii) asymmetrical tibial components that have an unique articular surface that allows for deeper knee flexion than has previously been available, (iv) asymmetrical femoral condyles that result in more physiologic loading of the joint and improved patellar tracking and (v) modifying an articulation surface of the tibial component to include an articulation feature whereby the articulation pathway of the femoral component is directed or guided by articulation feature.

A spinal interbody device fabricated of fully resorbable bioactive glass materials is used to maintain the intervertebral spacing in a fusion of adjacent vertebrae. The spinal interbody device can include regions of porous material having various levels of bioactivity so that fusion through ingrowth of bone tissue can be provided while regions of the spinal interbody device can continue to maintain the intervertebral space.

Techniques and systems for distracting a spinal disc space and supporting adjacent vertebrae are provided. Trial instruments are insertable into the disc space to determine a desired disc space height and to select a corresponding implant. Implants can be also be self-distracting and the implant providing the desired disc space height can be implanted in the spinal disc space.

An intervertebral implant for insertion into an intervertebral disc space between adjacent vertebral bodies or between two bone portions. The implant includes a spacer portion, a plate portion operatively coupled to the spacer portion and one or more blades for securing the implant to the adjacent vertebral bodies. The blades preferably include superior and inferior cylindrical pins for engaging the adjacent vertebral bodies. The implant may be configured to be inserted via a direct lateral trans-psoas approach. Alternatively, the implant may be configured for insertion via an anterior approach.

Embodiments described herein are related to pellets that are placed within an extraction site that is in need of bone augmentation and preservation. The pellets are typically cylindrical in shape and comprise a material and a polymer coating. The goal of the pellets are to encourage sufficient new bone growth that jaw bone deterioration is prevented. The pellets create, arrange, and assemble an ideal growth environment for new bone growth to rapidly grow and preserve the original contours of an individual's jaw bone.

A bone joint spacer has two endplates which have a bone engaging surface on one side, and ramps extending from an opposite side. A shaft has a threaded end, and another end which has ramp followers which mate with the endplate ramps of both endplates. A collar slides over the threaded end of the shaft, and also has ramp followers which mate with the endplate ramps of both endplates. A nut threads onto the end of the shaft and pushes the collar towards the ramp followers of the shaft. This movement causes the ramp followers to slide the ramp followers of the collar and the shaft against the endplate ramps, pushing the endplates apart. Two of these spacers can be combined by a link plate so that the spacers can be aligned or curved into a U-shape to be inserted into the body and positioned between bony surfaces, respectively.

Methods of implanting a talar component during ankle surgery are provided. A method includes cutting at least medial and lateral cuts in a talus bone. The method includes driving a first self-cutting distal edge of a lateral side wall of the talar component into the lateral cut and a second self-cutting distal edge of a medial side wall of the talar component into the medial cut. A thickness of the lateral sidewall tapers to form the first self-cutting distal edge and a thickness of the medial sidewall tapers to form the second self-cutting edge.
