Femoral shaft fracture

The femur is the longest tubular bone in the human body. The femoral shaft includes the bones 2-5 cm below the tuberosity to 2-5 cm above the femoral condyle. The femoral shaft is surrounded by three groups of muscles, of which the largest extensor muscle group is dominated by the femoral nerve; the flexor muscle group is followed by the sciatic nerve; the adductor muscle group is smallest and dominated by the obturator nerve. Because the thigh muscles are developed, there is often dislocation and overlap after fracture. The abductor muscle group around the femoral shaft is slightly weaker than other muscle groups. The abductor muscle group is located on the buttocks and attaches to the trochanter. Due to the function of the adductor muscle, the distal end of the fracture often moves inward. Positioning tendencies, fractures that have been aligned, often have a tendency to bow outward, and this tendency to shift and angle should be corrected and prevented during fracture treatment. When the lower 1/3 of the femur is fractured, because the blood vessels are located behind the femoral fracture, and the distal end of the fracture is often angled backward, it is easy to puncture the throbbing and veins there.
