Bone Healing

Bone Healing

The natural process of healing a fracture starts when the injured bone and surrounding tissues bleed. The blood coagulates to form a blood clot situated between the broken fragments. Within a few days blood vessels grow into the jelly-like matrix of the blood clot. The new blood vessels bring white blood cells to the area, which gradually remove the non-viable material.

The blood vessels also bring fibroblasts in the walls of the vessels and these multiply and produce collagen fibres. In this way the blood clot is replaced by a matrix of collagen. Collagen's rubbery consistency allows bone fragments to move only a small amount unless severe or persistent force is applied.

Since bone healing is a natural process which will most often occur, fracture treatment aims to ensure the best possible function of the injured part after healing. Bone fractures are typically treated by restoring the fractured pieces of bone to their natural positions (if necessary), and maintaining those positions while the bone heals. To put them back into the natural positions, the doctor often "snaps" the bones back into place. This process is extremely painful without anesthesia, about as painful as breaking the bone itself.

To this end, a fractured limb is usually immobilized with a plaster or fiberglass cast which holds the bones in position and immobilizes the joints above and below the fracture. If being treated with surgery, surgical nails, screws, plates and wires are used to hold the fractured bone together more directly. Alternatively, fractured bones may be treated by the Ilizarov method which is a form of external fixator.

Surgical methods of treating fractures have their own risks and benefits, but usually surgery is done only if conservative treatment has failed or is very likely to fail. With some fractures such as hip fractures (usually caused by osteoporosis or Osteogenesis Imperfecta), surgery is offered routinely, because the complications of non-operative treatment include deep vein thrombosis (DVT) and pulmonary embolism, 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. Infection is especially dangerous in bones, due to their limited blood flow. Bone tissue is predominantly extracellular matrix, rather than living cells, and the few blood vessels needed to support this low metabolism are only able to bring a limited number of immune cells to an injury to fight infection. For this reason, open fractures and osteotomies call for very careful antiseptic procedures and prophylactic antibiotics.

The healing time for broken bones is influenced by a number of variables that nutrition can impact including blood supply. For example, the ends of long bones are vascular so they heal faster than the center. Certain types of food and exercise foster increased blood supply and hence time it takes to heal. Mobilization, i.e. weight bearing exercises and isometric exercises stimulates healing.

Eating high calcium foods is esential for bone healing.

The key to better usage of your calcium intake is not just increasing the calcium but also increasing your ability to absorb the calcium. Lysine is an amino acid that helps in the absorption of calcium.

Vitamin C is essential nutritionally to make the collagen that helps the body form healthy bones.

Avoid Aspirin and anti-inflammatory drugs as they can retard bone healing. When you break a bone or tear a muscle and are on pain medication, you may want to try to stop taking the pain medication as soon as possible so you do not delay healing. A study in May 1995 issue of The Journal of Orthopedic Trauma shows damaged cells in a fracture release large amount of chemicals called prostaglandins. These chemicals cause the pain and are blocked by the pain medication. However prostaglandins are also very important in the first stage of tissue repair. So decreasing the use as soon as possible is helpful to the healing process.

Vitamin K, also called Menadione, is a very important fat-soluble vitamin that plays a key role in the regulation of normal blood clotting functions. We get vitamin K from several sources in our diet including dark leafy vegetables. Vitamin K also assists in converting glucose into glycogen for storage in the liver. Numerous studies indicate that it plays a role in forming bone formation and preventing osteoporosis. If you want to help bones heal faster, consider increasing your intake of Vitamin K rich foods.

Many studies have shown that broken bones tend to take longer to heal if the injured person has been smoking. Cigarettes can also increase the risk of blood clotting, which may further reduce blood flow. Breakdown products of cigarette smoke include carbon monoxide, formaldehyde, nitrosamines and benzenes which can damage the cells that form the bone itself and can interrupt the healing process after a fracture or bone injury.

Boron is important in bone healing because studies how show it reduces urinary excretion of calcium and magnesium and significantly increases blood levels of both estrogen and testosterone. The are many food high in boron. Apples are the highest.

To maximize the rate of healing it is helpful to avoid bone robbers such as sugar, salt, alcohol, caffeine, red meats etc.

Both silica and zinc are important for the repair of tissues. Silica is also important also in helping the calcium to be absorbed. Ensuring that these are in you diet is a another way to potentially decrease the time it takes to heal from a fracture.
