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 |

20120290017 | Bone fracture fixation clamp - A fixation clamp to stabilize a bone fracture comprising a pair of arcuate clamp members each including a concave inner surface having at least one spike-like element or protrusion extending outwardly from each concave inner surface to engage the bone surface to secure the fixation clamp in place pivotally coupled to each other and an adjustment device to tighten the arcuate clamp members around the bone forcing the spike-like elements or protrusions into the surface of the bone. | 11-15-2012 |
20130125903 | Fracture alignment device - A fracture alignment device to immobilize a patient's limb during a surgical procedure comprising an inner flexible layer and an outer flexible layer of fluid impervious material each including a central major portion or body having a plurality of lateral minor extensions or fingers extending outwardly therefrom to form a fluid tight chamber coupled to a pressure regulator to control the pressure within the fluid tight chamber and an alignment retainer to position and maintain the inner flexible layer in contact with the patient's limb when the pressure within the fluid tight chamber is sufficiently different from the ambient pressure outside the fluid tight chamber to immobilize the patient's limb. | 05-23-2013 |
20130131738 | BONE FRACTURE FIXATION CLAMP - A bone fixation clamp includes a first arcuate clamp member conforming to a shape of a bone and extending between a first connection end and a first free end, a second arcuate clamp member conforming to a shape of the bone, a second connection end of the second clamp member being pivotally attached to the first clamp member, the second clamp member extending between the second connection end and a second free end and a driving member received in the first clamp member passing out of the first clamp member to abut an abutment portion of the second member so that, as the driving member is extended further out of the first member, the driving member pivots the second clamp member relative to the first clamp member to draw the first and second free ends toward one another to apply a radially compressive force to the bone. | 05-23-2013 |
