Abstract: An orthopedic fixation system includes an implant and an implant insertion device. The implant transitions between a natural shape and an insertion shape and includes a bridge and first and second anchoring members extending from the bridge. The first and second anchoring members each include a segment extending exterior to the bridge to provide an engagement point. The implant insertion device moves between loaded and unloaded positions. The implant insertion device in its loaded position by-passes the bridge and engages the segment of the first anchoring member at its engagement point and the segment of the second anchoring member at its engagement point such that the implant insertion device constrains the implant in its insertion shape. The implant insertion device in its unloaded position releases the implant.

Abstract: An orthopedic fixation system including an orthopedic implant transitionable between a natural shape and an insertion shape. The orthopedic implant includes a bridge deformable to move the orthopedic implant between the natural shape and the insertion shape, a claw extending from the bridge at a first end thereof, and an anchor extending from the bridge at a second end thereof. The orthopedic implant when in the insertion shape affixes a bone fragment and a bone in that the anchor implants in the bone, the bridge extends over the bone and the bone fragment to position the claw at the bone fragment, and the claw captures the bone fragment. Moreover, upon an attempted transition of the orthopedic implant from the insertion shape to the natural shape, the orthopedic implant delivers energy stored therein to the bone fragment and the bone thereby affixing the bone fragment with the bone.

The present disclosure additionally describes a method of preparing an oil-infused BNC material that includes fermenting bacteria to form a porous body of bacterial nanocellulose fibers having a three-dimensional network defining a plurality of interconnected pores; mechanically pressing the porous body; dehydrating the porous body; and infusing the porous body with an oil infusion fluid including an oil so as to entrap the oil in the pores of the porous body forming an oil-infused BNC material.

Abstract: A storage system, including: a lid; a bottom side of the storage system opposite the lid; a first plurality of medical implants stored in a rack, wherein first plurality of medical implants are oriented in a first direction from the lid to the bottom side; a first drawer located between a portion of the first plurality of medical implants and the bottom side of the storage system; a second plurality of medical implants stored in the first drawer, wherein the second plurality of medical implants are oriented in a second direction that is substantially perpendicular to the first direction; and a drawer locking mechanism configured to engage the first drawer when the lid is closed to prevent the first drawer from sliding out of the storage system and to disengage the first drawer when the lid is open to allow the first drawer to slide out of the storage system.

Abstract: A central inflatable distractor and a perimeter balloon are inserted into the disc space in uninflated configurations. The central inflatable distractor is then expanded, thereby distracting the vertebral endplates to the controlled height of the central inflatable distractor. The perimeter balloon is then inflated with a curable substance. The perimeter balloon expands as it is filled with the curable substance and conforms to the void remaining in the disc space around the central inflatable distractor, thereby creating a horseshoe shape. Once the flowable material in the perimeter balloon has cured, the central inflated distractor can be deflated and removed. The remaining void (or inner space) is then packed with graft for fusion.

Abstract: A modular bone fixation linkage includes a plurality of interconnected links that can angulate with respect to an adjacent one of the links in-plane or out-of-plane. The links can further include fixation holes that are configured to receive fixation members that secure the links to an underlying anatomical structure.

Abstract: In an illustrative embodiment, a motor-driven orthopedic impacting tool for orthopedic impacting in the hips, knees, shoulders and the like may be capable of holding a surgical implement such as a broach, chisel, or other end effector, which when gently tapped in a cavity with controlled percussive impacts, can expand the size or volume of an opening of the cavity or facilitate removal of the surgical implement from the opening. A stored-energy drive mechanism may store potential energy and then release it to launch a launched mass or striker to communicate a striking force to an adapter in either a forward or reverse direction. The tool may further include a combination anvil and adapter and an energy adjustment mechanism to adjust the striking force the launched mass delivers to the adapter.

Abstract: An orthopedic impacting tool comprises a motor, a linear motion converter, an air chamber, a compression piston, an impacting element, an anvil element, and a broach adapter. The compression piston may cause the impacting element to apply controlled force on a broach adapter to create a precise opening for subsequently disposing a prosthesis in a patient. The tool allows forward or backward impacting for expanding the size or volume of the opening or for facilitating removal of the broach and tool from the opening. A force adjustment control of the tool allows a user to increase or decrease the impact force. A light source and hand grips improve ease of operation of the tool.

Abstract: An expandable intervertebral implant is provided for insertion into an intervertebral space defined by adjacent vertebrae. The expandable intervertebral implant includes a pair of outer sleeve portions and an inner core disposed between the outer sleeve portions. Movement of the inner core relative to the outer sleeve portions causes the outers sleeve portions to deflect away from each other, thereby engaging the expandable intervertebral implant with the vertebrae and adjusting the height of the intervertebral space.

Abstract: A retractor includes a first arm, a second arm, and a translating member. The first arm comprises a proximal portion configured to retain a first retractor member and a distal portion configured to rotate relative to the proximal portion about a first axis. The second arm is configured to retain a second retractor member, such that rotation of the distal portion about the first axis causes the first retractor member to pivot toward or away from the second retractor member when the first retractor member and the second retractor member are coupled to the first arm and the second arm, respectively. The translating member is coupled between the proximal portion and the distal portion, and is configured to receive a drive force that causes the translating member to bias the distal portion to pivot relative to the proximal portion about the first axis.

Abstract: A bone plate comprises a plate body and at least one tab. The plate body defines an inner body surface configured to face an underlying bone, an outer body surface opposite the inner body surface, and an outer side surface that extends between the inner body surface and the outer body surface. The outer side surface defines an outer perimeter of the plate body. The at least one tab includes a head and an arm that extends from the plate body to the head. The tab defines a tab aperture that extends through the head and is configured to receive a bone anchor. The bone anchor can be coupled with a screw hole in the nail. The arm is configured to deflect with respect to the plate body so as to move the head between a pre-fixation position and a fixation position spaced from the pre-fixation position.

Abstract: An example method is provided for maintaining stability to an injury defined by a separation of two bones (e.g., the tibia and fibula), the separation being an injured distance greater than a pre-injury distance between the two bones in a first human patient.
