Patent number: 11202668Abstract: A system and method for improving installation of a prosthesis, particularly an acetabular cup. The system and method may include implementation of a constant velocity relative motion between a prosthesis and an installation site. For example, an installation system may be fixed relative to the installation site, with the prosthesis fixed into an initial position. The prosthesis is moved at constant speed (i.e., with minimal if any acceleration or applied impulses) relative to the installation site. That is, one or both of the prosthesis or the installation site may be in motion. Resistive forces to installation of a prosthesis may thus be reduced by maintaining the prosthesis constantly in motion relative to the installation site. Securing a processing/implanting tool directly to the installation site may offer advantages.Type: GrantFiled: September 28, 2019Date of Patent: December 21, 2021Inventor: Kambiz Behzadi

The system also may include a plate member including (a) a mounting portion configured to be placed on and attached to a lateral cortex of the proximal femur and (b) a barrel portion configured to be placed into a lateral region of the proximal femur and positioned around a portion of the fixation element. The system further may include a compliant member positioned or positionable at least partially in the plate member and configured to be reversibly deformed in response to a load applied to the head of the proximal femur, to change an angular orientation of the fixation element with respect to the plate member.Type: GrantFiled: December 9, 2014Date of Patent: October 11, 2016Assignee: Acumed LLCInventors: Larry W. Ehmke, Steven P. Horst, Mark B. Sommers, Brian R. Conley

Patent number: 9456857Abstract: The present invention relates to an apparatus for the strictly limited flexible stabilization of long bone fractures, said apparatus incorporating a stabilization element configured to be a helical rod that may be introduced into the cavity of a long bone and that comprises a fixation device at one end at least. In accordance with the invention there is provided that the helical rod comprises, beside a very high vertical spring rate, a bending spring rate that is reduced to the “physiological” level as compared to a marrow nail so that, once placed in the bone, minimal healing-promoting movements are being stimulated. It is further preferred that the helical rod has a normalized, uniformly configured head that is independent of the variable outer diameter of the helical rod, which is adapted to the respective bone.Type: GrantFiled: April 2, 2009Date of Patent: October 4, 2016Assignee: H&R SPECIAL SPRINGS L.P.Inventor: Reiner Labitzke

Patent number: 9433451Abstract: System, including methods, devices, and kits, for hip fixation. The system may include a support member defining an aperture and including an intramedullary nail for a proximal femur or a plate member for a proximal femur. The system also may include a fixation element having a compliant region and configured to be received in the aperture of the support member such that the fixation element extends out of the support member from the aperture and into a head of the proximal femur and is slideable with respect to the support member along a long axis defined by the fixation element. The system further may include a set of stiffening inserts each insertable into the fixation element and configured to stiffen the compliant region differently from one another.Type: GrantFiled: December 10, 2014Date of Patent: September 6, 2016Assignee: Acumed LLCInventors: Larry W. Ehmke, Steven P. Horst, Mark B. Sommers, Brian R. Conley

Patent number: 9408648Abstract: Disclosed is a fracture fixation device, for reducing and compressing fractures in a bone. The fixation device includes an elongate body. An axially moveable proximal anchor is carried by the proximal end of the fixation device and comprises a tubular sleeve that includes a plurality of graduations positioned on an outer surface of the tubular sleeve. The device is rotated into position across the femoral neck and into the femoral head, and the proximal anchor is distally advanced to lock the device into place. In certain embodiments, the elongated body includes a distal anchor with a distal cutting tip.Type: GrantFiled: March 17, 2014Date of Patent: August 9, 2016Assignee: Interventional Spine, Inc.Inventor: Brad S. Culbert

Patent number: 9387011Abstract: A system is disclosed for repairing and reconstructing a joint which has been injured by trauma, and especially an acromioclavicular joint. Means are disclosed to strengthen the repair or reconstruction and to maintain alignment while the ligaments in the joint heal, thus allowing more aggressive rehabilitation. A new joint repair tool is disclosed which is inserted into two separated bones adjacent to their respective articular joint surfaces to connect the two bones and approximate the adjacent bearing articular joint surfaces while still allowing motion between the two bones. Instruments to perform the methods are also disclosed.Type: GrantFiled: February 2, 2007Date of Patent: July 12, 2016Inventor: Steven C. Chudik

Patent number: 9358052Abstract: The present invention relates to a device for fixation of bone fragments at bone fractures. The device comprises at least two fixation means (5, 6) and a securing plate (4). With the object of preventing or counteracting re-dislocation, the respective fixation means (5, 6) each have a first fixing portion (19) for fixing the fixation gleans in an inner bone fragment (3), a second fixing portion (21) for locking the fixation means to the securing plate (4) which is disposed on the outside of an outer bone fragment (2) and allows movement of the outer bone fragment relative to it, so that the fixation means are prevented from changing their angular position relative to the securing plate and relative to one another, and a middle portion (22) which is situated between the fixing portions and runs through the outer bone fragment, along which middle portion the outer bone fragment can slide inwards towards the inner bone fragment in which the fixation means is fixed.Type: GrantFiled: May 19, 2015Date of Patent: June 7, 2016Inventor: Henrik Hansson

Patent number: 9339311Abstract: A rear-retaining structure for dynamic hip screw (DHS) includes a retaining block and a positioning element. The dynamic hip screw comprises a lag screw, a sideplate, a sleeve with a higher orifice and a lower orifice, and a compression screw. The retaining block of the rear-retaining structure is attached to the sideplate of the dynamic hip screw by the positioning element. A stopper portion of the retaining block is located opposite to the lower orifice of the sleeve. The height of the highest point of the stopper portion in the lower orifice is in inverse proportion to the distance that the lag screw and the compression screw are allowed to slip back in the sleeve from an implant position to the lower orifice; namely, the higher the height of the highest point of the stopper portion is in the lower orifice, the smaller the distance for the slip back.Type: GrantFiled: November 24, 2014Date of Patent: May 17, 2016Assignee: INTAI TECHNOLOGY CORPORATIONInventors: Yung-Fang Tsai, Pei-Yuan Lee, Tsung-Chen Liu

Patent number: 9339313Abstract: A hip fracture support plate, in combination with hip screw fixation of an intertrochanteric hip fracture, provides additional support of the femoral head and neck fragment, tending to reduce hip screw cut-out or fracture, with collapse and mal-union of the head and neck.Type: GrantFiled: May 20, 2015Date of Patent: May 17, 2016Inventor: Roy Y. Powlan

Patent number: 9333013Abstract: The invention relates to a plate fixed between two bone parts by way of screws engaged in holes formed in the thickness of said plate. The plate comprises an angled member or rib which is inclined according to an angle of between about 30° and 60° in relation to the plane defined by the plate. The angled member or rib has a hole for engaging a screw and is located in the central part of the width, over a determined part of the length of the plate, so that the screw brings the two bone parts into a compressive position.Type: GrantFiled: June 9, 2015Date of Patent: May 10, 2016Assignee: Stryker European Holdings I, LLCInventors: Bernard Prandi, Keith Wapner, Charles P. Wapner, Peter W. Wapner
