Publication number: 20130178860Abstract: A drill guide for guiding elements, especially drill bits and implants of an implantation kit during a surgical intervention, has a main body having a gripping portion. The drill guide has an upper and a lower central opening along its longitudinal axis with a through going cavity for receiving the element to be guided. A lower contact surface is positioned on an object, such as a bone, on or into which the element is to be guided. The diameter of the through going cavity can be varied by a.) radial positioning of three or four jaws inside the cavity through a groove-slide block system and/or b.) against the force of a spring at the lower free end of guiding extensions. The spring is provided on the back side of the extensions which bear against the inner wall of the drill guide sleeve.Type: ApplicationFiled: January 4, 2013Publication date: July 11, 2013Applicant: STRYKER TRAUMA SAInventor: STRYKER TRAUMA SA

Publication number: 20130165932Abstract: A fixation clamp, more particularly for use in an external fixation system for holding bone fragments adjacent to each other with the help of fixation elements, has at least one clamping assembly having at least one reception opening to accommodate a fixation element along the longitudinal axis of the reception opening. At least one locking element extends through the clamping assembly which locking element provides a clamping force to clamp the fixation element upon tensioning the locking element. The fixation clamp further comprises an actuation element which is in connection with the locking element such that the locking element is actuateable by means of the actuation element, and the actuation element is designed such that it is detachable from the locking element after use and that remounting onto the locking element is prevented after having detached the actuation element from the locking element.Type: ApplicationFiled: February 21, 2013Publication date: June 27, 2013Applicant: Stryker Trauma SAInventor: Stryker Trauma SA

Publication number: 20130165930Abstract: A system for fixing a wire to a surface of an external fixator having a wire adapted to extend through bony structure fastened with respect to the surface. A bolt having a shaft which comprises a threaded section, a head section and at least one clamping element is provided wherein the bolt is adapted to extend through an opening in the external fixation element with a nut, and clamps the wire to the surface. A counter torque tool is used to provide a counter torque while fastening the wire with the bolt and the nut. The bolt comprises a counter torque opening and wherein the counter torque tool comprises a section which is adapted to engage into the counter torque opening of the bolt to apply the counter torque.Type: ApplicationFiled: February 19, 2013Publication date: June 27, 2013Applicant: STRYKER TRAUMA SAInventor: STRYKER TRAUMA SA

Publication number: 20130165979Abstract: A wrist fusion plate has a proximal portion comprising at least one opening, wherein the proximal portion attaches to the radius by inserting bone screws through the proximal portion opening. A distal plate portion has a plurality of openings and is adapted to be attached to a metacarpal (M) by inserting bone screws through the distal portion attachment openings and into the metacarpal. A central plate portion has at least one attachment opening and is adapted to be attached to a carpal bone by inserting bone screws through the attachment opening. The proximal and distal portions are aligned along a longitudinal axis of the wrist fusion plate. One of the distal portion attachment openings is elongated in a direction perpendicular to the longitudinal axis.Type: ApplicationFiled: December 13, 2012Publication date: June 27, 2013Applicant: STRYKER TRAUMA SAInventor: Stryker Trauma SA

Publication number: 20130144289Abstract: A fixation clamp for use in an external fixation clamp has a clamping assembly having a reception to accommodate a fixation element. The clamp has a locking element extending through the clamping assembly for blocking the position in a defined angular position. A washer is arranged between the locking element and a central opening of the clamping assembly having a cutout extending radially from the through opening such that the washer is mountable and demountable in a radial direction to a locking element longitudinal axis. The cutout has a smaller distance between its sidewalls then the diameter of the through opening. The locking element has circular cross-section below its head portion adapted to fit through the through opening of the washer but larger than the opening of the cutout and has at least one pair of parallel beveled surfaces spaced closer than the distance between sidewalls of the washer cutout.Type: ApplicationFiled: December 6, 2012Publication date: June 6, 2013Applicant: STRYKER TRAUMA SAInventor: STRYKER TRAUMA SA

Publication number: 20130110175Abstract: A bone plate system is disclosed which includes a bone plate having at least one plate hole, at least one pin adapted to be disposed in the at least one plate hole, and a polymer component disposed between the at least one pin and the bone plate. The polymer component includes a polymer that may be melted through the application of ultrasonic energy. The at least one pin is constructed of a material that will not melt under such application of ultrasonic energy. The re-solidified polymer component creates a bond between the at least one pin and the bone plate to provide a more rigid and secure mating therebetween, and to at least substantially prevent backout of the at least one pin with respect to the bone plate. A method of implanting the bone plate system is also disclosed.Type: ApplicationFiled: December 20, 2012Publication date: May 2, 2013Applicant: STRYKER TRAUMA SAInventor: Stryker Trauma SA

Publication number: 20130079775Abstract: An adjustment tool for an external fixator comprises a fitting element for holding fast a clamping assembly of the external fixator. A positioning clamp is provided for fixing the adjustment tool on a rod of the external fixator near the clamping assembly. A connecting element is attached to the fitting element and the positioning clamp is adapted to move the fitting element towards to or away from the positioning clamp. The fitting element comprises a blocking sleeve adapted to push the uppermost jaw of the clamping assembly in the direction of the longitudinal axis of the clamping assembly to block the second upper most jaw against an abutment portion of the fitting element. The tool further comprises an actuation element within the blocking sleeve to actuate the locking element of the clamping assembly for releasing the rod within the clamping assembly without releasing the bone pin.Type: ApplicationFiled: September 25, 2012Publication date: March 28, 2013Applicant: Stryker Trauma SAInventor: Stryker Trauma SA
