An improved method and apparatus for reducing a hip fracture utilizing a minimally invasive procedure which does not require incision of the quadriceps. A femoral implant in accordance with the present invention achieves intramedullary fixation as well as fixation into the femoral head to allow for the compression needed for a femoral fracture to heal. To position the femoral implant of the present invention, an incision is made along the greater trochanter. Because the greater trochanter is not circumferentially covered with muscles, the incision can be made and the wound developed through the skin and fascia to expose the greater trochanter, without incising muscle, including, e.g., the quadriceps. After exposing the greater trochanter, novel instruments of the present invention are utilized to prepare a cavity in the femur extending from the greater trochanter into the femoral head and further extending from the greater trochanter into the intramedullary canal of the femur. After preparation of the femoral cavity, a femoral implant in accordance with the present invention is inserted into the aforementioned cavity in the femur. The femoral implant is thereafter secured in the femur, with portions of the implant extending into and being secured within the femoral head and portions of the implant extending into and being secured within the femoral shaft.

A device for preventing a hip fracture includes: a shaft having a first end and a second end and an expanding means for engaging the femoral head at the first end. The shaft is positioned in a hole of a predetermined depth in a femur. The hole extends from the greater trochanter to the femoral head of the femur, such that the first end is positioned in the femoral head and the second end is positioned in the greater trochanter. The device is oriented substantially perpendicular to the long axis of the femoral shaft.

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.

An anti-subsidence dynamic hip screw comprises of a barrel having a connection portion and a tube-type extending portion angled a predetermined angle with the connection portion, and a first long groove and a first limit portion disposed at the inner wall of the extending portion respectively; a lag screw having an inside end disposed threading screw at its outer edge and a outside end with a predetermined length passed through in the extending portion by the way of reciprocation; a second long groove and a second limit portion disposed at the lag screw respectively related to the first long groove and the first limit portion, each first limit portion and second limit portion used for preventing the lag screw from rotating inside the extending portion; a blade piece with a predetermined length simultaneously passed through and retained in the first long groove and the related second long groove; a compressing screw having an inside end screwed with the outside end of the lag screw and an outside end retained in the outside end of the extending portion. The above structure is not only easy to assembly, especially for the effect of decreasing the subsidence of the femoral head, but also makes the effect more obvious when using for the hip fracture of the osteoporosis body.

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.

Methods and apparatus for orthopedic replacement of the hip and hip fracture fixation devices include structures and techniques for fixing or enhancing interconnection of implant components, such as by increasing the interconnection in an interference fit with one or more tapers, threads, and / or cooling of components prior to assembly. For example, a prosthetic femoral neck implant can include a thread and a Morse taper for lockable attachment to a prosthetic femoral head and / or intramedullary stem.
