Abstract: A retractor assembly includes a base, a first side assembly, a second side assembly, and a medial arm assembly. The first side assembly is coupled to a first side of the base and translates relative to the base along a first direction. The second side assembly is coupled to a second side of the base and configured to translate relative to the base along the first direction. The medial arm assembly is coupled to the base and can extend in an extension direction and retract in a retraction direction. The extension direction is opposite the retraction direction. The extension direction and the retraction direction are perpendicular to the first direction. The medial arm assembly includes a body, and a blade assembly. The blade assembly includes a receiving portion and a medial blade. The receiving portion and the medial blade are rotatably interfaced via a ball and a socket.

Abstract: A spine plate implant utilizes cam lock setscrews to retain bone screws in the plate once implanted. A cam lock setscrew is received in a setscrew pocket adjacent a configured bone screw bore of the plate and is configured to allow a bone screw to be received in the plate when in an unlocked rotational position, and to retain the received bone screw when in a locked rotational position. The bone screw may include a tang that allows engagement with external teeth of the cam lock setscrew when the cam lock setscrew is rotated into the locked position. Once the cam lock setscrew is in the locked position, the bone screw is inhibited from backing out of the bone screw bore. When the cam lock setscrew is in the unlocked position, a flat of the cam lock setscrew is adjacent the bone screw tang so the bone screw may be removed.

Abstract: The invention is a subtalar implant able to expand after implantation. The subtalar implant has two or more expansion segments or wings. In all forms, the expansion wings are hinged on the distal portion of the subtalar implant which causes only the proximal portion of the wing to expand relative to the midplane of the implant. The expansion wings and the entire subtalar implant are threaded to prevent the implant from backing out of the sinus tarsi once implanted. In one form, the subtalar implant includes an integral expansion screw that, when rotated, expands the expansion wings. In another form, the subtalar implant includes a separate expansion screw that, when rotated, expands the expansion wings. The integral and the separate expansion screw includes a socket that accepts a like driver tool for rotating the expansion screw and expanding the expansion wings.

Abstract: A device for insertion into a spinal (intervertebral or intravertebral) space is expandable and contractable. The device includes a body assembly, a top member configured to fit within a gap in the body assembly, a drive gear disposed within the body assembly at a distal end of the body assembly, a proximal gear assembly, and a distal gear assembly. The drive gear includes a receiver accessible from outside the body assembly and configured to be rotated in order to rotate the drive gear. Each gear assembly is attached to the top member. The distal gear assembly engages the drive gear. Rotation of the drive gear in a first direction causes the gear assemblies to translate the top member away from the body assembly, and rotation of the drive gear in a second direction causes the gear assemblies to translate the top member towards the body assembly.

Abstract: A spinal implant for immobilizing the C1 vertebra with respect to the C2 vertebra of the spine provides controlled coupling between the C1 and C2 vertebrae, and includes a C1 component attachable to the C1 vertebra, two C2 components attachable to the C2 vertebra, and a transverse element. The C1 component has two wings each of which retains a rod holder that rotates and translate for capturing a C2 component rod. Each C2 component has a hook for connection with a side of the C2 vertebra lamina and a rod for attachment to one of the rod holders of the C1 component. Each C2 component receives and secures the transverse connector which holds position of the C2 components relative to one another. Each C2 component may include a plate configured for compression against the C2 vertebra spinous process, with each plate including spikes to aid in preventing construct migration.

Abstract: A medical instrument set and method of use for surgically treating bony aberrations of the calcaneus such as calcaneal compression fractures. The present medical instrument set allows surgical treatment of bony aberrations through a minimally invasive procedure that provides better outcomes than both a closed reduction and an open reduction procedure. The medical instrument set includes one or more of an access needle, drill, depth guide, cement plunger, and curette. The access needle is used to provide access to a desired calcaneal site and is characterized by a cannula and a removable trocar tip. The drill is used to bore into the calcaneus. The depth guide is used to visually indicate how far a medical instrument extends beyond and/or through the access needle cannula. The cement plunger is used to introduce bone cement into the desired calcaneal site. The curette is used to mechanically create a void at the desired calcaneal site.
