Fracture in the upper part of the femur.

Method and apparatus for reducing femoral fractures

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.

Hip fracture device with barrel and end cap for load control

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.

Bone plating system for treatment of hip fractures

The current invention is a bone plating system comprising a plate and screws. The plate resembles the average shape of the outer surface of the proximal femur (hip region). Cancellous screws through the plate are used to create compression between bone fragments and “locking” screws to create a stable connection between screw and plate. Each screw can accomplish either compression, stable connection with the plate or both. Screw holes in the plate can be slotted, thereby allowing for insertion of screws in relatively different positions to each other with regards to the screw entry points within the plate.
