Description
Technical Field
The utility model relates to the technical field of orthopedic implants, in particular to a femur far-end outer side locking bone fracture plate with an inner side column support.
Background
The distal femur includes the supracondylar and intercondylar regions of the femur, and the overall annual incidence of fractures at the distal femur is reported in the literature to be about 8.7/100000, about 0.4% of total fractures, and 6% of total fractures. Epidemiological studies reflect the characteristic bimodal distribution of distal femur fractures, with peaks occurring in men under 40 and women over 50. In young people, high-energy injuries such as traffic accidents are frequently seen, and in old people, fractures can be caused by low-energy injuries such as falling and falling during walking due to osteoporosis and the like. As the population ages, the incidence of fractures at the distal femur will also increase.
The current preferred treatment scheme for the distal femur fracture is incision reduction internal fixation surgery treatment, and the treatment aims at restoring the lower limb force line, realizing the healing of the fractured end and early restoring the knee joint movement. Early fixation of distal femur fractures often presents high probability of non-union, implant failure, varus collapse, etc., with continued progress in treatment over the last 60 years. Currently, there are many options for surgical treatment of distal femur fractures, including open or minimally invasive access placement of locking plates, intramedullary nail fixation, etc., see patent nos. CN208905683U, CN210095888U and CN212140567U, etc.
However, the unilateral steel plate has poor shearing force and torsion resistance, fracture delayed healing or non-healing is easy to occur when the blood supply of the affected side is poor, the literature reports that the failure rate of bone nonunion and implants is still 10% -20%, and the reason of the distal femur bone nonunion is possibly related to the instability of the medial condyle and the failure of providing sufficient biomechanical support. In order to solve the problem, the concept of double fixation is proposed at present, namely, steel plates are used for fixation or steel plates are combined with intramedullary nails and the like on the inner side and the outer side, but the surgical time is obviously prolonged, and the surgical wound is increased.
