| 20100036431 | Bone end (Epiphysis) fracture fixation device and method of use - A bone end (epiphysis) fracture device including a rotatable fixation plate having a guide pin aperture and a plurality of fixation screw apertures formed therethrough. The guide pin aperture is used by a surgeon to position the fixation plate so that one or more fixation screw apertures are properly positioned to receive fixation screws inserted by the surgeon for repairing a bone end fracture. In another embodiment, the fracture fixation device also includes a side plate to which the fixation plate is rotatably attached. This embodiment further includes one or more side plate apertures formed through an elongate extension, whereby the fixation device may also be attached to the bone for which an end fracture is being repaired. A lock screw is provided in this embodiment for locking the position of the fixation plate with respect to the side plate. | 02-11-2010 |
| 20100114323 | KNEE PROSTHESIS KIT WITH WINGED SLEEVES AND MILLING GUIDE - A knee prosthesis kit includes single-winged and double-winged metaphyseal sleeve components. A milling guide and reamers in the kit allow for a cavity to be prepared to receive the metaphyseal sleeve components by pivoting one of the reamers on a portion of the milling guide. The instruments allow the cavity to be aligned with the intramedullary canal regardless of the relative hardness of the bone in the vicinity of the cavity. | 05-06-2010 |
| 20110054474 | TARGETING JIG FOR HIP FRACTURE NAIL SYSTEM - An instrument system is provided for positioning an internal fixation prosthesis and guiding a cannulated bone drill during a surgical, radioscopic procedure for the repair of a fractured bone of a patient. The instrument system includes a target wire, a handle formed from a radio translucent material having a target hole for guided passage of the target wire along a target axis. The target axis coincides with the intersection of a first plane and a second plane orthogonal to the first plane. The instrument system also includes a nose component attached to an end of the handle and removably connectable to the prosthesis. The nose component includes an alignment sight formed from a radio-opaque material. When the prosthesis is connected to the nose component and the target wire is positioned through the target hole along the target axis, the image of the guide wire may be radioscopically viewed along a first line of sight contained in the first plane to bisect the image of the alignment device, thereby providing a first visual reference to the user for directing the first guide wire into the desired portion of the bone while holding the prosthesis in a desired position relative to the bone. | 03-03-2011 |

| 20080255559 | Orthopaedic trauma hip screw assembly and associated method - A hip screw assembly for fixation of a fractured femur is provided. The hip screw assembly includes a screw for engagement with the femur. The hip screw assembly also includes a barrel defining a cavity in the barrel. The barrel is fixedly secured to the plate. The screw including a portion thereof fitted in the cavity of the barrel. The hip screw assembly also includes a stop positionable in the barrel. The stop provides a limit on the movement of said screw in said barrel. The screw and the barrel have a first arrangement between each other in which the screw slides in the cavity of said barrel a first selectable predetermined distance and a second arrangement in which the screw slides a second selectable predetermined distance. The second distance is greater than the first distance. | 10-16-2008 |

| 20090248025 | Intramedullary nail with coupled shafts - A nail assembly for use in trauma surgery is provided. The nail assembly includes an intramedullary shaft including a first transverse passage and a second transverse passage in the shaft. The, first transverse passage and the second transverse passage do not contact each other on the shaft. The nail assembly also includes a first shaft extending through the first transverse passage in the intramedullary shaft and a second shaft extending through the second transverse passage in the intramedullary shaft. The second shaft includes an engagement feature configured to bring the second shaft into contact with the first shaft. The engagement feature may be in the form of a lateral mechanical feature that provides simultaneous unilateral coupled motion of the first shaft with the second shaft through the transverse passages in the intramedullary shaft. | 10-01-2009 |
