The three most difficult fracture healing parts

Femoral neck fracture, 1/3 fracture of lower leg and scaphoid fracture of wrist are the three most difficult fracture healing parts in human body. Femoral neck fracture is easy to damage the blood supply to the femoral head, such as the internal femoral circumflex artery, which is the main blood vessel supplying the femoral head. Therefore, it is easy to cause ischemia and aseptic necrosis of the femoral head after fracture, thus affecting the healing of the fracture. 2. Lower 1/3 fracture of the lower leg, i.e. lower 1/3 fracture of the tibia and fibula. Because there is less soft tissue around the bone and the blood supply is poor, it is not easy to heal once the fracture occurs here. After the fracture of the middle and lower 1/3 segment of tibia and fibula, due to less soft tissue coverage, the fracture end is easy to expose, and the blood circulation is poor, resulting in difficult healing of the fracture end and easy non-union. The scaphoid bone of the wrist is a small bone in the wrist joint with a special shape and important position. After the scaphoid bone fracture, due to its low blood supply,

(Mainly from the surrounding soft tissue joint capsule, lumbar blood vessels are the main blood vessels), and the wrist joint mobility is large, so fracture healing is more difficult. After scaphoid fracture, due to insufficient blood supply and joint movement, fracture end is easy to shift and unstable, resulting in delayed fracture healing or even non-union. In addition, scaphoid fracture is also easy to cause ischemic necrosis and absorption, further increasing the difficulty of healing.
