In a first broad aspect, there is provided herein a bioactive device and system for fusion between two bones, two parts of a bony joint, or a bony defect, such as of the spine. The fusion device includes a screw having a head and a threaded shaft. The fusion device also includes a bone dowel having an internal bore of which at least a distal portion is threaded to engage the threads of the screw shaft. The bone dowel is made of a bone-like, biocompatible, or allograft material to provide a layer of bone-like, biocompatible, or allograft material between the screw and the spinal bone. The device is generally coaxial and is further described in the drawings and description herein.

A dental implant made of a material comprising titanium. The implant includes a head portion having a non-rotational feature, a lowermost end opposing the head portion, and a threaded bottom portion for engaging bone between the head portion implant and the lowermost end. The implant further includes a nanocrystalline surface formed on at least a portion of the implant. The nanocrystalline surface includes discrete nanocrystals deposited on a roughened surface of the implant. The roughened surface includes at least one of a grit-blasted surface or an acid-etched surface. A portion of the roughened surface is exposed between at least some of the discrete nanocrystals such that the exposed roughened portion between the discrete nanocrystals is capable of contacting bone.

The present invention relates to dynamic bone fixation elements and a surgical method to stabilize bone or bone fragments. The dynamic bone fixation elements preferably include a bone engaging component and a load carrier engaging component. The bone engaging component preferably includes a plurality of threads for engaging a patient's bone and a lumen. The load carrier engaging component preferably includes a head portion for engaging a load carrier (e.g., bone plate) and a shaft portion. The shaft portion preferably at least partially extends into the lumen. Preferably at least a portion of an outer surface of the shaft portion is spaced away from at least a portion of an inner surface of the lumen via a gap so that the head portion can move with respect to the bone engaging component. The distal end of the shaft portion is preferably coupled to the lumen.

The invention primarily relates to fastening and stabilizing tissues, implants, and/or bondable materials, such as the fastening of a tissue and/or implant to a bondable material, the fastening of an implant to tissue, and/or the fastening of an implant to another implant. This may involve using an energy source to bond and/or mechanically to stabilize a tissue, an implant, a bondable material, and/or other biocompatible material. The invention may also relate to the use of an energy source to remove and/or install an implant and/or bondable material or to facilitate solidification and/or polymerization of bondable material.

Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment. Mounting members include, for example, flanges, blades, hooks, and plates. In some embodiments, the orthopedic attachments may be adjustably positionable about the base member or other attachments, thereby providing modularity for assembling and implanting the device, and various securing and/or locking mechanisms may be used between the components of the implant.

A bone anchor includes an anchor member including a first material, and having a tubular section extending along a longitudinal axis, a region configured to expand radially outwards from the longitudinal axis, and a bone engagement structure projecting from at least a portion of the expandable region of the tubular section, and a core member including a second material, and configured for insertion into and connection to the anchor member. When the core member is in the anchor member and is actuated relative to the anchor member, the tubular section is adjustable between a first position where the expandable region of the tubular member has a first length and a first maximum diameter, to a second position where the expandable region of the tubular member has a length shorter than the first length and a maximum diameter greater than the first maximum diameter.

An implant, a method for production thereof, and use thereof for growing patients are disclosed, containing a Mg—Zn—Ca-based alloy. In order to meet extremely strict requirements with regard to compatibility, chemical resistance, and mechanical strength, it is proposed that the alloy contain 0.1 to 0.6 wt % zinc (Zn), 0.2 to 0.6 wt % calcium (Ca), and a remainder of magnesium (Mg), as well as impurities that are an inevitable part of the manufacturing process, which each total no more than 0.01 wt % and altogether total at most 0.1 wt %, with the quotient of the percentages by weight of Zn and Ca being less than or equal to 1.

This disclosure is directed to surgical fixation devices (e.g., staples, screws, etc.) which are able to bring bone fragments into close proximity with each other, generate a compressive load, and maintain that compressive load for a prolonged period of time while healing occurs. The surgical fixations devices are manufactured from a shape memory material (e.g., a material capable of exhibiting superelasticity and/or a temperature-induced shape change).

A flexible tubular member for guiding insertion of instrumentation to a bone screw affixed within bone includes a tubular body that is flexible, constructed of textile material, and defines a longitudinal axis. The tubular body also defines a proximal end and a distal end opposite each other along the longitudinal axis. The tubular body further defines a guide channel that extends from a proximal opening at the proximal end to a distal opening at the distal end. An attachment member is located at the distal end of the tubular body and is configured to couple the distal end to a proximal portion of the bone screw. The attachment member has an annular shape around the guide channel and is configured to expand responsive to a predetermined tensile force applied to the tubular body for decoupling from the bone screw

Bone plates for engaging bone members are described herein. The bone plates can receive one or more screws to secure the bone plates to an underlying bone member. The one or more screws can be inserted into bone plate holes that can be considered locking or non-locking. The bone plates described herein can have particular combinations of locking and/or non-locking holes. In addition, instruments such as distal and proximal aiming guides can accompany the bone plates to guide one or more screws into the bone plates.
