Femoral neck fractures and intertrochanteric fractures are both proximal femur fractures, but they are very different: 1. In terms of location, the femoral neck is closer to the joint and is surrounded by the joint capsule, so femoral neck fractures are intracapsular, while intertrochanteric fractures are extracapsular. Fractures of the femoral neck are generally less displaced and less painful because they are encapsulated by the joint capsule. The bleeding at the fracture end is concentrated in the joint capsule, and because of the restraint of the joint capsule, there is no obvious local swelling and petechial hemorrhage or the swelling and petechial hemorrhage is less, and the shortening and external rotation deformity of the affected limb is also less. Because the intertrochanteric fracture is located outside the joint capsule, the trochanter is cancellous bone and there are more muscle attachment points, so the fracture displacement is usually larger, the pain is more severe than that of the femoral neck fracture, there is more bleeding at the fracture end, the local soft tissue swelling and subcutaneous petechial hemorrhage is more severe, the external rotation and shortening deformity of the affected limb is obvious, and the functional impairment is serious; 2. There are also differences in treatment between the two. The treatment of femoral neck fracture depends on the age and fracture displacement, and artificial joint replacement can be considered for older fractures, such as over 60 years old with serious fracture displacement.
