Ⅰ. What are the four types of femoral fractures?
1. Proximal femur fracture
Femoral neck fracture: It is common in elderly patients with osteoporosis and can easily lead to ischemia and necrosis of the femoral head.
Intertrochanteric fracture: The fracture line is located between the greater trochanter and the lesser trochanter, with better blood supply and higher healing rate.
Subtrochanteric fractures: occur under the small trochanter, mostly caused by high-energy injuries, and often require surgical treatment.
2. Femoral shaft fracture
Fractures occur in the middle of the femur and are often caused by direct violence (e.g., car accidents, falls), often accompanied by significant displacement and soft tissue damage.
3. Distal femur fracture
Supracondylar fracture of the femur: close to the knee joint, may involve the articular surface, and requires anatomical reduction to restore joint function.
Interfemoral intercondylar fractures: involving the medial and outer femoral condyles, articular plane flatness needs to be evaluated to prevent traumatic arthritis
Ⅱ. What precautions should be taken during femoral nail surgery?
After surgery, the main attention should be paid to the following aspects: First, pay attention to the blood seepage of the surgical incision, and use antibiotics appropriately for 24~48 hours after surgery to prevent infection. The surgical incision is changed regularly, and the drainage is removed within 24 hours. Second, perform hip and knee joint activities and functional exercises as soon as possible after surgery. Intramedullary nails for femoral shaft fractures include nails that need to be nailed through the hip or knee joints, which will cause certain damage to the soft tissues around the joints and may cause blood accumulation in the joints. Therefore, it is recommended to perform joint mobilization early after surgery to prevent complications such as joint adhesions, and also reduce the formation of deep vein thrombosis in the lower extremities. Third, it is not recommended to carry weights too early after surgery, and it is necessary to regularly review X-rays to understand the growth and healing of the fracture stump, and to promote fracture healing appropriately through drugs.
Ⅲ. What is the difference between PFN A and A2?
PFN-A and A2 are two completely different concepts, the former is an internal fixation device for the treatment of femoral intertrochanteric fractures (anti-rotation proximal femoral intramedullary nail), and the latter is a classification of femoral intertrochanteric fractures in the AO typing system.
PFN-A is a specific surgical internal fixation device, which stands for “Proximal Femoral Nail Anti-rotation”. It is an intramedullary nail system that fixes fractures by inserting them into the femoral medullary cavity, with the characteristics of anti-rotation and stable fixation, and is mainly used for the treatment of intertrochanteric fractures of the femoral femoral with AO types A1, A2, A3 and high subtrochanteric fractures
A2 is a type description of intertrochanteric femoral fractures in the AO classification system and is classified as an unstable fracture. According to the AO classification, type A2 fractures are characterized by a fracture line passing through the trochanteric region and a rupture of the medial cortex in at least two places with a high number of fracture blocks. It is further subdivided into:
Type A2.1 : There is an intermediate fracture mass between the trochanters.
Type A2.2: There are multiple intermediate fracture blocks between the trochanters.
Type A2.3 : The fracture line extends more than 1cm below the small trochanter
In short, PFN-A is a therapeutic tool and A2 is the type of fracture . Clinically, doctors will choose the appropriate internal fixation method according to the AO classification of the patient’s fracture (such as type A2), and PFN-A is one of the common surgical methods for the treatment of unstable intertrochanteric femoral fractures such as type A2
