INTRAMEDULLARY ROD WITH PIVOTABLE FASTENER AND METHOD FOR USING SAME
An intramedullary rod for use with a fastener to repair a femur includes an elongate nail extending along a longitudinal axis and having a stem and a head. The head is provided with an aperture extending along an axis at an angle to the longitudinal axis for receiving the fastener. A mechanism is carried by the head for pivoting the axis of the aperture from a first angled position relative to the head to a second angled position relative to the head. A method for using the rod and fastener is provided.
STERILIZATION TRAY FOR FACILITATING ATTACHMENT OF IMPLANT INSERTION DEVICE TO IMPLANTABLE DEVICE, RELATED APPARATUS AND METHODS
An apparatus including a sterilizable tray having a base and at least one fixture connected to the tray adapted for removably securing an implant insertion device to the tray. The tray can be free of a first wall portion for permitting the proximal end of an implantable device to axially align with the end of the implant insertion device for coupling to the implant insertion device and can be free of a second wall portion for permitting a tool to axially align with the end of the implant insertion device so as to threadedly couple the implant insertion device to the implantable device. Related methods and apparatus are provided.
Method for pivoting a fastener
An intramedullary rod for use with a fastener to repair a femur includes an elongate nail extending along a longitudinal axis and having a stem and a head. The head is provided with an aperture extending along an axis at an angle to the longitudinal axis for receiving the fastener. A mechanism is carried by the head for pivoting the axis of the aperture from a first angled position relative to the head to a second angled position relative to the head. A method for using the rod and fastener is provided.
Implant insertion device with continuously adjustable targeting assembly
An implant insertion device including a body having a first portion for coupling to a proximal end of an intramedullary rod and a second portion extending in a spaced position from the intramedullary rod in the vicinity of an aperture in a proximal end of the rod when the rod is coupled to the first portion. The second portion can include a targeting assembly having a passageway for receiving a guide sleeve and for pivoting the guide sleeve relative to the aperture through an angular range for inserting the fastener into the aperture of the rod. An implant insertion device for use with an implantable device is additionally provided.
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.
INTERLOCKING INTRAMEDULLARY ROD ASSEMBLY FOR PROXIMAL FEMORAL FRACTURES, INCLUDING UNSTABLE HIP FRACTURES
An interlocking intramedullary rod assembly for treating a fracture of a bone, said interlocking intramedullary rod assembly comprising: an intramedullary rod comprising a distal section and a proximal section; a distal interlocking screw; and a proximal interlocking screw; wherein said distal section of said intramedullary rod comprises a static distal seat for receiving said distal interlocking screw, and said proximal section of said intramedullary rod comprises a dynamic proximal seat for receiving said proximal interlocking screw; and further wherein said static distal seat is configured to secure said distal interlocking screw to said intramedullary rod such that said distal interlocking screw cannot move relative to said intramedullary rod, and said dynamic proximal seat is configured to secure said proximal interlocking screw to said interlocking rod such that a first end of said proximal interlocking screw cannot move relative to said intramedullary rod and the second end of said proximal interlocking screw can move relative to said intramedullary rod.
Bone end (epiphysis) fracture fixation device and method of use

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.
HIP FIXATION WITH LOAD-CONTROLLED DYNAMIZATION
System, including methods and apparatus, for hip fixation with load-controlled dynamization. In exemplary embodiments, the system may comprise a fixation element, such as a screw, configured to be placed into a proximal femur of a subject, with a leading end of the fixation element anchored in a head of the proximal femur. The system also may comprise a stop member configured to be connected (e.g., via a nail or plate) to the proximal femur. The system further may comprise a deformable member configured to be irreversibly deformed by compressive force exerted on at least a portion of the deformable member by the fixation element and the stop member in response to a load applied to the proximal femur by the subject, such that the fixation element and the stop member move relative to one another parallel to a long axis of the fixation element.
EXPANDIBLE-EXTENDIBLE INTRAMEDULLARY NAIL
The expandible-extendible intramedullary nail includes a base section. An assembly component is connected to the base section. The assembly component has an inner assembly surface and helical assembly threads formed on the inner assembly surface. A distal rod is connected to the assembly component. A driving nut is connected to the distal rod and assembly component. The driving nut has an outer nut surface and helical nut threads formed on the outer nut surface. The driving nut is rotatable about the longitudinal central axis of the helical nut threads such that the rotation causes helical displacement of the helical nut threads relative to the helical assembly threads. This causes longitudinal displacement of the distal rod relative to the assembly component.
Photodynamic articular joint implants and methods of use
Photodynamic devices for replacement of an articular head of a bone are provided. In an embodiment, a photodynamic device includes a photodynamic support member and an articular member attachable, either fixedly or removably, to the photodynamic support member and having a bearing surface. In an embodiment, the articular member includes a recess designed to receive the photodynamic support member. In an embodiment, the photodynamic support member includes an opening into which a shaft of the articular member can be inserted to attach the articular member to the photodynamic support member.
