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: A method for providing a tool system for removing prosthetic cement from a bone of a patient undergoing a joint prosthesis replacement operation includes scanning the patient in the area of the joint prosthesis to obtain a profile of a line of intersection of a prosthetic cement/bone interface at its intersection with a longitudinally pre-selected plane; providing a guide member shaped as a stem of the prosthesis in a prosthetic cavity located in said prosthetic cement; and providing a cutting tool for forming a running cut through the prosthetic cement along the line of intersection. A stem of the cutting tool includes two protrusions along the length thereof. A guide member includes two grooves which each engage one of said protrusions. Grooves are profiled so the outer end of the stem is forced to follow a path corresponding to the profile of the line of intersection of the cement/bone interface.

Abstract: A system and method for installation of a k-wire through a scaphoid or other fractured bone can include a guide block for accurate trajectory of a k-wire. A support frame for a guide block can be casted and/or secured into place, and a CT scan is obtained, so the fractured bone and the location of the window can be known in the same three-dimensional space. An ideal k-wire trajectory can be plotted through the fractured bone, and a guide block with a lumen can be designed and printed using a three-dimensional printer. The guide block can be inserted into the frame so the lumen aligns with the ideal k-wire trajectory, and a k-wire can be inserted through the lumen into the fractured bone. The net effect would be ideal placement of the k-wire that would facilitate the ultimate insertion of a percutaneous screw to provide fixation of the fractured bone.

Abstract: A medical balloon device includes an outer member extending along an axis. An inflatable member has a proximal end extending from a first end of the outer member and a distal end. An inner member is positioned within the outer member and the inflatable member such that a first end of the inner member is coupled to the distal end of the inflatable member. A support member is movably disposed within the inner member and includes a first end configured to removably engage the first end of the inner member. Translation of the support member along the axis causes the inflatable member to move between a first position in which the inflatable member has a first length and a first profile and a second position in which the inflatable member has a second reduced length and a second reduced profile. Methods of use are disclosed.
