The concept

The concept of this website is based on a previous site that was founded in 2008 and is still up and running. The website is composed as a book, where all sources are properly referenced, according to a good practice in scientific publications.

    Winquist and Hansen classification of femoral shaft fractures - fracture of thigh bone

    Winquist and Hansen classification, usually abbreviated by the name of the first author, divides fractures of femoral shaft into four grades according to the amount of bone comminution. Sometimes, grade V is reffered to as a segmental bone loss. However the original classification contains only four grades.

    Grade Description
    Grade I no comminution or minimal comminution with a small wedge fragment < 25% of the circumference of the bone
    Grade II comminuted fracture with a wedge fragment <50% of the circumference of the bone
    Grade III comminuted fracture with a large wedge fragment >50% but less than 100% of the circumference of the bone
    Grade IV segmental comminution with no abutment of main fragments
