Abstract: A flexible shaft includes a tubular body extending along a central longitudinal axis and having proximal and distal ends opposite one another. The flexible shaft also includes a slot defined by the tubular body and extending along a helical path around and along at least a portion of the body between the proximal and distal ends. The helical path extends around the portion of the body for a plurality of rotations. The slot defines at least two teeth adjacent one another along a direction parallel to the central axis. Each tooth of the two teeth has a feature. In some implementations, a line extending through center points of the features on the two teeth is angularly offset from the central longitudinal axis. In some implementations, a line parallel to the central longitudinal axis intersects a different point on each feature of the two teeth.

Abstract: An osteotomy instrument for compression and/or distraction spinal procedures includes a first leg and a second leg pivotally attached to the first leg. The first leg and the second leg each include a proximal portion, a distal portion with a distal end and a pocket extending within the distal end towards the proximal portion. The distal portion of each leg is configured to rotatably engage a bearing attached to a spine of a patient. The pocket may be generally hemispherical with an inner surface configured to engage the bearing and form a ball-in-socket joint with the bearing.

Abstract: A reamer shaft extension includes a shaft positioned between a first end having a first coupling and a second end having a second coupling. The first coupling of each reamer shaft extension is selectively couplable with the second coupling of another reamer shaft extension such that a select amount of reamer shaft extensions are assembled together to form a reamer shaft extension assembly for use in a reaming procedure. Each reamer shaft extension further has a sufficiently short enough length such that each reamer shaft extension is insertable within a sterilization tray for use in a sterilization procedure.

Abstract: A multi-layered implant and methods of forming the multi-layered implant are disclosed. The multi-layered implant includes a Metal Injection Molded body comprising a titanium alloy, a porous coating layer on a first surface of the Metal Injection Molded body, and a zirconium alloy layer on a second surface of the Metal Injection Molded body. The first surface and the second surface are on opposite sides of the Metal Injection Molded body. A zirconia layer may be formed over the zirconium alloy layer. The porous coating may be a titanium-based porous coating.

Abstract: An alignment guide is provided for aligning a cannulated intramedullary reamer shaft with a guidewire. The alignment guide includes a tray, a guidewire alignment flange extending from a rear portion of the tray, and a reamer shaft alignment flange extending from a front portion of the tray. The guidewire alignment flange includes a sidewall curved to form a first recess within the sidewall. The reamer shaft alignment flange includes at least one tab having a curved portion to form a second recess within the at least one tab. The first and second recesses are aligned along a longitudinal axis to position the reamer shaft and guidewire along the longitudinal axis.

Abstract: Some embodiments of the invention may provide a bracket assembly for selectively receiving a stem portion of a medical device therein. The bracket assembly may be movably or permanently disposed within a case or tray assembly. The case or tray assembly may then be placed within a sterilization chamber such as an autoclave to sterilize the medical device. The bracket assembly includes a main body coupled with a gripping element for selectively clamping or otherwise holding the stem portion of the medical device therein in response to pressing the medical device into the gripping element.

Abstract: Instruments for inserting an implant in a space between adjacent bony portions include upper and lower guide members separated by a spreader with the implant positioned forwardly of the spreader. The spreader is movable forwardly between the guide members with a drive member to position the implant in a space between the bony portions. The spreader contacts the adjacent bony portions to facilitate withdrawal of the inserter instrument when the implant is positioned in the space.

Abstract: An angular surgical driver including a first rotatable member, a second rotatable member, an angled housing and a plurality of pins. The first rotatable member and second rotatable member are angularly associated with each other. The angled housing is rotatably connected to the first rotatable member and the second rotatable member. A plurality of pins drivingly connecting the first rotatable member to the second rotatable member.

Abstract: The present invention comprises a set of instruments and a method for their use in preparing a knee joint to receive knee implants. The inventive instruments and method are generally suitable for knee joint surgery. Furthermore, they include features that make them suitable for performing a minimally invasive knee surgery in which a smaller than normal incision is made and oriented to preserve the quadriceps mechanism and protect the suprapatellar pouch. The instruments permit switching from a minimally invasive technique to a standard open technique at any point in the procedure. An illustrative set of instruments for total knee arthroplasty and an associated minimally invasive technique are described.

Abstract: An interbody spacer for insertion between vertebral members. The spacer includes a body having posterior and anterior sides, and inferior and superior faces. The spacer further includes a plurality of teeth to maintain the position of the spacer between the vertebral members. The teeth are aligned in a pattern and have a shape to allow insertion into the space between the vertebral members, and prevent or limit movement once the spacer is positioned in the space.
