20080269752 | Hip fracture device with barrel and end cap for load control - A hip fracture device providing distance limited dynamization, load controlled dynamization and combinations of both dynamization methods by varying components. The hip fracture device includes a plate having a head portion and a shaft portion. A barrel projects from the head portion of the plate and a screw is inserted in the barrel. A friction pin is slidably connected with the screw, and an end cap is fixed to the head portion of the plate. The friction pin is fixedly connected with the end cap. The screw slides over the friction pin and toward the end cap when a load is applied on the fracture device. The load required for further sliding of the screw over the friction pin increases incrementally as the screw slides towards the end cap. | 10-30-2008 |
20080269807 | Hip fracture device with static locking mechanism allowing compression - A bone plate having a plurality of openings for receiving a compression bone screw or a cortical screw. An end cap, threadably insertable in the opening and having a layer of polymeric material interposed between the end cap and the top of the head such that the compression of the polymeric material would allow slight axial movement of the screw. Alternatively, a locking ring adapted to attach to the head of the screw and having shape complimentary to the features formed on the head. The locking ring and the bone screw being assembled together and being insertable in the bone simultaneously using a dedicated instrument. Compression may be applied to a bone fracture by turning the bone screw alone after the locking ring has reached its final axial position. | 10-30-2008 |
20110213379 | COMPUTER ASSISTED SURGERY SYSTEM - A computer assisted surgery system and a method for operating a computer assisted surgery system is described therein. The system and method includes providing a virtual representation of a medical device to provide an easier application of a medical device, such as an implant or the like. The described system and method allows for simple and fast positioning of a medical device to be applied, such as an implant, for example. | 09-01-2011 |
20130211386 | SURGICAL TARGETING SYSTEM AND METHOD - A targeting system is used for positioning of a medical sub device with respect to a medical device. A reference body is reproducibly positioned with respect to a targeting device coupling section and reproducibly positioned with respect to a targeting unit. The targeting unit has a targeting direction and is adjustable with respect to the targeting device so that the targeting direction points toward a medical sub device receptacle of the medical device coupled to the targeting device coupling section. The imaging system is positionable with respect to the targeting device such that the imaging system is capable of imaging a single two-dimensional view of the reference body and the medical sub device receptacle. The evaluation unit generates position data of the single two-dimensional view and to determine from the position data a lateral distance between the targeting direction and a receiving direction of the medical sub device receptacle. | 08-15-2013 |
20130314440 | VIRTUAL 3D OVERLAY AS REDUCTION AID FOR COMPLEX FRACTURES - A method and device for assisting reduction for complex fractures includes the steps of receiving an x-ray image of a fractured bone having a plurality of bone fragments, identifying structural aspects of at least one of the bone fragments, adapting a virtual bone model to the imaged bone based on the identified structural aspects, and generating an overlay of the virtual bone model onto the x-ray image, with the virtual bone model aligned to the identified structural aspects. The device is adapted to perform the method. | 11-28-2013 |
20130315371 | BONE DENSITY MEASUREMENT - A method and device for determining a tissue density based on an x-ray image including a reference body. The method uses a device for receiving an X-ray image of a region of interest and information about a theoretical distribution of more or less dense tissue in the region of interest. Pixels of the X-ray image related to tissue are compared with a pixel related to a reference body. The actual distribution of tissue density is estimated based on the received information and the result of the pixel comparison. | 11-28-2013 |
20140094802 | INTRAMEDULLARY NAIL AND IMPLANT SYSTEM COMPRISING THE NAIL - An intramedullary nail has a posterior side, an anterior side, a proximal portion and a distal portion is described. A transverse bore is arranged in the proximal portion and is configured to receive a bone engagement member. The transverse bore includes at least two recesses formed at an inner wall of the transverse bore, wherein one recess is arranged on the posterior side and the other recess is arranged on the anterior side of the transverse bore of the intramedullary nail. | 04-03-2014 |
20140148861 | HIP FRACTURE DEVICE WITH STATIC LOCKING MECHANISM ALLOWING COMPRESSION - In one embodiment, the present invention is a method of fusing fractures of a femoral neck using a bone plate including the steps of: placing a bone plate on the femur; inserting an assembly of a bone screw and a locking ring in an opening in the plate; simultaneously threading the locking ring and the bone screw in the femur; threading the bone screw in the femur to compress the fracture; creating a space between the locking ring and the bone screw; and allowing the bone screw to move towards the locking ring when the femur is loaded. In another embodiment, the present invention is a bone plating system including a bone plate having a plurality of openings; at least one bone screw capable of being received through the opening and into a bone; at least one end cap fixedly insertable in the opening; and a layer of polymeric material interposed between the end cap and the top of the head. | 05-29-2014 |
20140163571 | DISTAL TARGETING DEVICE - A targeting device for targeting a cross bore in a bone nail has an arm member coupled to an end portion of the bone nail and an aiming portion forming part of the arm member extending parallel to a longitudinal axis of the bone nail. An adjustable aiming device is mounted on the aiming portion, the adjustable device having a guide bore alignable with the cross bore in the nail. The adjustable device is moveable with respect to the aiming portion in a direction perpendicular to a plane containing both the nail longitudinal axis and central axis of the cross bore. A target indicator is mounted on the adjustable aiming device. The target indicator has a radiolucent body including first and second spaced parallel planar portions each having a spaced radiopaque element therein. | 06-12-2014 |
20140214035 | BONE NAIL WITH SMOOTH TRAILING END - A bone nail has a shaft with a leading section and a trailing section, wherein the trailing section includes an end surface having at least one depressed portion and at least one elevated portion. The transition between one of the depressed portions and the adjacent elevated portion is smooth. The end surface is formed so as to transmit rotational forces as well as translational forces from a medical device to the shaft of the bone nail, when the medical device is coupled at the end surface to the trailing section of the bone nail. | 07-31-2014 |
20140214098 | MODULAR LAG SCREW - An elongated modular implant is provided which has a distal part and a proximal part both having a leading end and a trailing end, respectively. The trailing end of the distal part includes a tool engagement portion and the leading end of the proximal part includes a distal part engagement portion for an engagement with the tool engagement portion of the distal part. The implant further includes an assembly element for firmly coupling the distal part and the proximal part when the first tool engagement portion of the distal part engages the distal part engagement portion of the proximal part. The proximal part trailing end may also have a tool engagement portion identical to the trailing end of the distal part. | 07-31-2014 |
