Femur Fracture Types
The 3 types of femoral shaft fractures are as follows:
The comminuted femur fracture is a break in which there are three or more fragments of the femur resulting from tremendous pressure. These are very common in car accidents. Comminuted femur fractures can be especially difficult to treat, as the fragments can make things complicated for the doctor.
An open femur fracture tends to be the most gruesome. This is when high pressure is exerted on the femur and the bone tears through the thigh tissue and skin. You're basically looking at an exposed bone with blood loss. These are very serious and should be taken care of immediately.
Other notes: Diaphyseal fractures result from significant force transmitted from a direct blow or from indirect force transmitted at the knee. Pathologic fractures may occur with relatively little force. These may be the result of bone weakness from osteoporosis or lytic lesions.
