General characteristics
Breaks or cracks in a bone are known as fractures. A fracture can occur in any bone of the body and can result from an accident such as a fall or when more pressure is put on the bone than it can cope with. Breaks can present in a wide variety of ways such as a clean break, chips breaking off or a hairline fracture across or along the length of a bone. They can also occur as a result of diseases like osteoporosis.
Clean fractures where the surrounding tissues are not ruptured or injured is called a simple or closed fracture. These tend to be uncomplicated and healing is relatively straight forward.
When the soft tissues or skin surrounding the bone is also damaged it is called an open or compound fracture. These are more serious as blood spills into the tissues, complicating healing and allowing the possibility of infection into the fracture site.
Bones are normally excellent healers as they have their own built in repair mechanisms so need little help in many cases. Sometimes things do go wrong and extra help is needed. For example, the bones of the elderly often take longer to heal, sometimes the ends of broken bones are not 'set' (do not meet) properly or blood supply to the bone is damaged delaying or disrupting healing.
Bone cells called osteoclasts eat away and reabsorb any damaged bits of bone then bone building cells called osteoblasts lay down new healthy bone tissue to replace what is needed. The bone forming cells tend to make slightly more bone than is needed so the area where the bone has newly healed has a slight bump around it (callus) which slowly fades away over time.
Herbs and natural healing aim to ensure a proper blood supply to and from the area, assist the natural defences in fighting any infection and help ensure the smooth process of the bone healing process.
