General Fractures

Falls cause bone fractures. So do accidents. A bone fracture is a medical condition in which a bone is cracked or broken. Many fractures result from high force impacts or stress. Bone fractures also develop from medical conditions that weaken bones, such as osteoporosis, certain types of cancer, or osteogenesis imperfecta (a condition causing extremely fragile bones).

Fractures are classified in many ways. A simple, closed fracture is much easier to treat than an open, contaminated fracture:

  • In a closed fracture the skin is intact. An open, or compound fracture, involves wounds that communicate with the fracture and may expose the bone to contamination. Open fractures carry a higher risk of infection, require antibiotics, and usually require surgical treatment (debridement), to remove dirt, contamination, and dead tissue.
  • A simple fracture occurs along only one line. It splits the bone into two pieces. Multi-fragmentary fractures occur when the bone splits into multiple pieces.
  • Compression fractures occur when the front portion of a vertebra in the spine collapses due to osteoporosis.

Treatment

A bone fracture may be very painful due to the stimulation of nerve receptors, swelling, and muscle spasms. Since bone healing is a natural process, fracture treatment aims to ensure the best possible function of the injured part after healing. Typically, fractured pieces of bone are restored to their natural positions, with verification provided by an x-ray. A fractured limb is held in place with a plaster or fiberglass cast or splint. Once the initial swelling goes down the fracture may be placed in a removable brace. Surgery is done only if conservative treatment has failed, or is likely to fail. Surgery is routine on hip fractures due to osteoporosis. That’s because the complications of non-operative treatment includes deep vein thrombosis (the formulation of a blood clot in a deep vein) and pulmonary embolism (a blockage in an artery due to air, fat, blood clot, or tumor), which are more dangerous than surgery. When a joint surface is damaged by a fracture, surgery is also commonly recommended to make an accurate anatomical reduction and restore the smoothness of the joint.
