The invention belongs to the field of
medical equipment, and particularly relates to an anti-rotation intramedullary nail
system of a proximal femoral bionic arm reconstruction support. The anti-rotation intramedullary nail
system comprises a main nail and a pressure nail, and is characterized by further comprising at least one tension nail, wherein the main nail, the pressure nail and the tensionnail form at least one triangular support structure, a near end section and a far end section of the main nail are integrally formed, the near end section is provided with a first nail hole and a second nail hole, the first nail hole fixes the tension nail, and the second nail hole fixes the pressure nail. The anti-rotation intramedullary nail
system has the beneficial effects that the system isconsistent with
anatomy of the femoral
medullary cavity in a
lateral position, the main nail of the side bent proximal femoral anti-rotation intramedullary nail can be lengthened even to the overall length of the femoral
medullary cavity, and then the system can be used in
femoral shaft fracture and multiple femoral fractures, thereby enlarging the use scope; the system effectively prevents the hip joint from inverting,
femoral neck from shortening, femoral part from displacing inwardly, and
femoral head and neck from rotating and deforming, an internal fixing device is prevented from breaking, loosing and releasing from the
femoral neck internal fixing device, a power screw or a screw blade is prevented from
cutting out, and
femur stress fracture is prevented.
