In some embodiments, systems, spinal constructs, surgical instruments and methods are disclosed. In some embodiments, systems, spinal constructs, surgical instruments and methods are disclosed.

The invention discloses a Zn—Ga series alloy and a preparation method and application thereof, belonging to the technical field of medical alloys. The Zn—Ga series alloy includes Zn and Ga, and Ga accounts for 0-30 wt % but not including 0. The preparation method is to mix Zn and Ga or Zn, Ga and trace elements, then to obtain a Zn—Ga series alloy by coating paint after smelting or sintering. The mechanical properties of the prepared Zn—Ga series alloy meet the requirements of the strength and toughness of medical implant materials, and it can be degraded in vivo. It has the dual characteristics of biological corrosion degradation and suitable corrosion rate to provide long-term effective mechanical support.

The current invention is directed to a medical implant made of bulk-solidifying amorphous alloys and methods of making such medical implants, wherein the medical implants are biologically, mechanically, and morphologically compatible with the surrounding implanted region of the body.

A surgical instrument includes a first member defining a longitudinal axis and including a drive interface engageable with a first surface of a bone fastener. The first surface is configured for penetrating a sacrum. A second member includes a drive interface engageable with a second surface of the bone fastener to translate the second surface relative to the first surface such that the second surface engages an outer non-articular surface of an ilium to draw separated articular surfaces of the sacrum and the ilium into fixation. In some embodiments, systems and methods are disclosed. Systems and methods are disclosed.

The present invention relates to the preparation methods and applications of biodegradable zinc-copper alloys, which can be applied to medical implant materials. The alloy of present invention is mainly composed of copper (1-10 wt. %), the balance of zinc and trace impurity elements. As-cast alloy ingot is homogenized and then hot processed to refine microstructure. The mechanical properties of the alloys are improved due to the refined microstructure. The alloys are capable of being further fabricated into micro-tubes, wires and plates. There are many advantages of these Zn alloys such as excellent mechanical properties, easy to process, appropriate corrosion resistance, good biocompatibility and so on, which correspondingly can be applied to many kinds of biodegradable medical implant devices. With excellent mechanical properties, good biocompatibility and degrading completely in 6-18 months, the Zn alloys meet the requirements of implant materials for mechanical properties and biosafety.

Compression devices for joining tissue and methods for using and fabricating the same.

A medical grade thermoplastic or polymer implant with an osteoconductive coating is provided, specifically for corrections of the distal and proximal interphalangeal toe joints of the foot. The implant can be either straight or angled, and can be either solid or cannulated for insertion. The implant is sized and shaped depending on the specific anatomy and desired correction. End portions of the implant may be coated with an osteoconductive coating that promotes bone growth, but may reduce radiolucency. Thus, a central portion of the implant may remain uncoated to increase radiolucency of the implant at the region where two bones come together.

A method for fusing two adjacent stacked bones includes the following. First, inserting first and second pins into first and second locations of a first surface of one of the two adjacent stacked bones, respectively. Next, inserting a dilator over each of the first and second pins to dilate tissue around the first and second pins. Next, inserting a tissue protector over the dilator and removing the dilator. Next, inserting a cannulated drill through the tissue protector over each of the first and second pins and drilling first and second openings in the first and second locations, respectively, wherein the first and second opening extend through the two adjacent stacked bones. Next, tapping threads in the first opening and inserting a first bone fusing implant in the first opening, wherein the first bone fusing implant comprises threads configured to engage the threads of the first opening. Next, impacting a broach into the second opening to generate a pattern corresponding to a pattern of a second bone fusing implant and then inserting the second bone fusing implant in the second opening.

Method for manufacturing a bone pin for connection to a bone, particularly for fixing an implant to a bone, the bone pin having an implant contacting part arranged to contact the implant in connected situation and a bone contacting part arranged to engage the bone in connected situation, wherein the method comprises the steps of:—providing bone information which is indicative for the bone which the bone contacting part is arranged to engage;—providing a bone contacting part which is customized on the basis of the bone information for engaging said bone;—providing an implant contacting part; and—assembling the bone contacting part and the implant contacting part for manufacturing the pin.
