What is the pathophysiology of femur fracture?


What is the pathophysiology of femur fracture?

Femoral-shaft fractures are usually the result of trauma. Motor vehicle accidents, pedestrian-versus-vehicle accidents, falls, and gunshot wounds are among the most common causes. Pathologic fractures in adults are most often the result of osteoporosis and metastatic disease.

What are the three mechanisms of injury with regard to femur fractures?

Femur fractures are typically described by location (proximal, shaft, distal). These fractures may then be categorized into three major groups; high-energy traumatic fractures, low energy traumatic fractures through pathologic bone (pathologic fractures) and stress fractures due to repetitive overload.

What is right femur fracture?

A femur fracture is a break, crack, or crush injury of the thigh bone. It is sometimes referred to as a hip fracture or broken hip when the break is in the upper part of the bone near the hip joint area. Femur fractures that are simple, short cracks in the bone usually do not require surgery.

Is distal femur fracture common?

Distal femur fractures include fractures of the supracondylar and intercondylar region and are relatively common injuries. The goals of treatment follow AO principles of anatomic reduction of the articular surface, restoration of limb alignment, length, and rotation.

What is the pathophysiology for a healing fracture?

Phases of fracture healing The inflammatory reaction results in the release of cytokines, growth factors and prostaglandins, all of which are important in healing. The fracture haematoma becomes organised and is then infiltrated by fibrovascular tissue, which forms a matrix for bone formation and primary callus.

What is fracture of femur?

The long, straight part of the femur is called the femoral shaft. When there is a break anywhere along this length of bone, it is called a femoral shaft fracture. This type of broken leg almost always requires surgery to heal. The femoral shaft runs from below the hip to where the bone begins to widen at the knee.
