Embodiment Construction

[0020] Such as figure 1 As shown in Embodiment 1 of the present invention, the interlocking intramedullary nail fixation system for femoral neck fractures includes a metal rod 1 with a thread 11 at one end and a plurality of channels in different orientations that traverse the metal rod body at the other end. Hole 12, the inner wall of through hole 12 is all provided with screw thread, and all are screwed with locking nail 2 in each through hole 12; Described through hole 12 can also only be provided with;

[0021] After the femoral neck fracture is reset, a bone tunnel is first made from the femoral trochanter 3 to the femoral head 4, and the metal rod 1 is screwed into the bone tunnel after tapping, and one end of the metal rod 1 provided with a thread 11 is fixed on the bone tunnel. In the femoral head 4, then the locking nail 2 is screwed into the through hole 12 at the other end of the metal rod 1, and the locking nail 2 is penetrated through the cortical bone of the femo...

Abstract

An intramedullary needle fixing system with lock for the fracture of femur neck is composed of a metal rod transplanted between femur head and tuberosity part, a locator at the femur head end of said metal rod for preventing the relative rotation between femur head and tuberosity part, and a connector at the tuberosity end of said metal rod for connecting the metal rod to tuberosity part.

Description

technical field [0001] The invention relates to an intramedullary nail fixation system for fractures, belonging to the technical field of medical devices. Background technique [0002] At present, for the treatment of femoral neck fractures, internal fixation or artificial joint replacement can be used according to the specific conditions of the patient. Both methods can obtain satisfactory fracture healing effect, and have been widely used in the world. Since hollow nails or DHS are semi-threaded screws, they can continuously pressurize the fractured end of the femoral neck. Although the advantage of this continuous pressurization is that it can promote fracture healing, its disadvantage is that it will cause fractures of the femoral neck after healing. The femoral neck is shortened, which causes two problems. On the one hand, the gluteus medius muscle is relatively weak due to the shortened femoral neck, and the shortening will seriously affect the normal gait of the pati...
