The pelvis is a ring of bones located at the lower end of the trunk, between the spine and the legs. A fractured pelvis is almost always painful. This pain is aggravated by moving the hip or attempting to walk. Most pelvic fractures are caused by some type of traumatic, high-energy event, such as a car collision. In some cases, a lower-impact event—such as a minor fall—may be enough to cause a pelvic fracture in an older person who has weaker bones.
A hip fracture is a break in the upper portion of the femur (thighbone). Most hip fractures occur in elderly patients whose bones have become weakened by osteoporosis. When a hip fracture occurs in a younger patient, it is typically the result of a high-energy event, such as a fall from a ladder or vehicle collision.
Your thighbone (femur) is the longest and strongest bone in your body. Because the femur is so strong, it usually takes a lot of force to break it. Femur fractures vary greatly, depending on the force that causes the break. The pieces of bone may line up correctly (stable fracture) or be out of alignment (displaced fracture). The skin around the fracture may be intact (closed fracture) or the bone may puncture the skin (open fracture).
A pilon fracture is a type of break of the shinbone (tibia) that happens near the ankle. Most of the time, it includes breaks in both the tibia and fibula of the lower leg. The lower ends of these bones make up part of the ankle.
A fracture of the calcaneus, or heel bone, can be a painful and disabling injury. This type of fracture commonly occurs during a high-energy event—such as a car crash or a fall from a ladder—when the heel is crushed under the weight of the body. When this occurs, the heel can widen, shorten, and become deformed.
