Bones make up the skeleton of the body. They allow us the ability to interact with our environment and lift out body up against gravity. Bones are attachment points for muscles which allows us to run, jump, sit, kneel, grasp, and lift. Bones also protect organs from potential damage, and the bone marrow (tissue inside of bones) is responsible for blood cell production.
Bones are the body's storage area for calcium. On a cellular level, calcium is always entering and exiting bone under the influence of the body's hormones. Parathyroid hormone increases calcium levels in the bloodstream, meaning, that it regulates it's release by bone and decreasing bone density. Calcitonin decreases blood calcium levels and helps restore calcium to bone. Calcium is needed in the blood stream to help muscle cells including the heart to function. Hormone levels will sacrifice calcium in bone to maintain blood calcium levels in a normal range. For that reason, calcium and Vitamin D are important to maintain calcium stores in the body.
When a bone has an outside force exerted upon it, like a blow or a fall, there is potential that it cannot withstand the amount of force and it breaks. That loss of integrity results in a fracture. It is important to remember that a fracture, break, or crack all describe the same situation, an injury to the bone where it has been damaged. One term is not more serious than another. Fracture, break, and crack all mean the same thing.
Depending upon the situation, the amount of force required may not be very great. People with osteoporosis, the bones lack calcium and are brittle, a minor injury or even gravity may create enough of a force to cause a vertebral compression fracture of the back or a hip fracture.
Fractures are usually described by their location, how the bones are aligned, whether there are associated complications with blood and nerve function, and whether the skin is intact at the injury site.
The terms and definitions used in medicine to describe fractures allow health care professionals to describe exactly where in the bone the fracture is located. For a reference point, the heart is considered the center of the body and the anatomic descriptions are based on their location in reference to the heart. When describing a location on or in the body, imagine standing straight up, looking forward with the arms slightly away from your side, and the palms turned forward.
Common anatomic terms used to describe fractures include the following:
By thinking of the body in the anatomic position, fractures can be described by their location in the bone and how the parts are aligned and related to each other. Fractures are either displaced or non-displaced, meaning that they are adequately aligned or not. Some physicians suggest that all fractures have some displacement and prefer the term "minimally displaced."
The description of the fracture also includes the direction it takes within the bones.
Special terms:
Fractures are classified as open (if the skin is damaged) or closed (if the skin is intact). An open fracture may require an orthopedic surgeon to wash out the fracture site to prevent osteomyelitis (bone infection). Depending upon circumstances, the type of fracture, the amount of contamination to the skin and wound, and the person's condition, this procedure may take place in the operating room.
The spine is comprised of 7 cervical, 12 thoracic, and 5 lumbar vertebrae. The spine holds the body erect against gravity and to protect the spinal cord. Compression fractures can be caused by osteoporosis, injury, or trauma.
The purpose of the skull is to protect the brain. It is a flat bone and it takes a significant direct blow to cause a fracture. Because the main concern is an injury to the brain and not the skull injury , plain X-rays are not routinely performed to look for a skull fracture. Instead CT scan of the brain is recommended if there is concern about a brain injury. Skull fractures are often associated with localized swelling and bleeding at the site of injury.
Basilar skull fractures describe damage to bone at the base of the brain. Physical findings may include bloody drainage from the ear or nose, bruising behind the ear (Battle's sign), and bruising around the eyes (Raccoon eyes).
With a depressed skull fracture, the bone is broken and fragments are pushed inward. Depending upon depth of the bony depression and whether there is brain tissue involvement, surgery may be required.
With an open skull fracture, the scalp is lacerated and the wound may connect with the fibrous coverings of the brain (meninges). Surgery is often performed to help prevent infection.
Stress fractures are the result of multiple microtraumas where the bone cannot tolerate and absorb repeated stresses placed upon it. It is an overuse injury and is often seen in the lower leg especially with runners and other athletes. If untreated, and if the person continues to participate in offending activity, the stress fracture may progress to a completed fracture. These are most often seen in athletes who participate in running, tennis, basketball, and other sports that involve running and jumping on hard surfaces.
March fracture is the name given to a stress fracture of the metatarsal bone of the foot. They are described in soldiers who are forced to walk or "march" for prolonged distances.
The most common fractures involve the clavicle (collarbone), the forearm (radius and ulna), the wrist, the ankle and the hip. Closed fractures are more common than open fractures (the skin overlying the injury is intact and not damaged).
In children, a fracture of the distal radius is most common. The break occurs in the radius near the wrist but usually does not involve the joint itself. 1
Injuries to the hands and fingers are very common because they are exposed in daily activities. In addition to the bones, the health care professional will be interested in making certain there are no tendon or nerve injuries associated with any broken bone(s). Because the anatomy of the hand is so complex, complicated fractures may be referred to an orthopedic or plastic hand specialist. Many of them will only require splinting or casting, but occasionally surgery will be necessary.
Falling on an outstretched hand is the most common reason for a wrist fracture. It is often the distal radius (see illustration) that is damaged, and the fracture may involve more than one bone. Aside from the radius, wrist fractures may also include fractures of the carpal bones of the wrist (carpus), those that connect the radius to the long bones of the hand (metacarpals). Doctors often look for fractures of the scaphoid bone (the bone between the bottom of the thumb and the top of the radius), and dislocations of the lunate (the bone next to the scaphoid bone) that may be difficult to see on plain X-ray.
In some cases, the wrist is splinted even if X-rays are normal because upon physical examination the doctor may be concerned about a potential occult or hidden fracture (the fracture is so small that it does not show up on an X-ray).
Depending upon the bone that is injured and it's alignment, surgery may or may not be required. Regardless of the treatment, the goal is to have a normally aligned wrist, especially if the fracture involves the joint surface. Poor alignment may lead to arthritis in the future.
Hip fractures are perhaps the most common fracture seen in people 75 years of age or older. While falls and trauma may be the obvious cause, many times, people are more susceptible to hip fracture because of osteoporosis and sometimes the hip will break spontaneously.
The hip joint is made up of the interconnection of two bones in a ball and socket: 1) the socket in the pelvis (acetabulum), and 2) the ball (femoral head). Hip fractures refer to the femur fracture.
Almost all hip fractures require surgery and the type of surgery depends upon where in the femur that the fracture is located.

Each of the many bones of the lower extremity is at risk for fracture. Leg fractures also may involve the knee joint, and treatment depends upon the type of fracture. Similarly, fractures of the lower leg (tibia and fibula) and talus (the most proximal bone in the foot) may involve the ankle joint.
Fractures and dislocations of the foot may be as complex as the hand. Because of the anatomy, they may also be more difficult to diagnosis on plain X-rays.
Broken toes are a common fracture and may be diagnosed by history and physical examination. X-rays may or may not be needed depending upon the clinical situation.
The clavicle (collarbone) fracture is one of the most commonly seen broken bones, fracture of the humeral head (the ball) is quite common an older person who falls.
Depending upon the amount of comminution (into how many pieces the humeral head breaks) surgery may or may not be required. Initial treatment usually begins with a sling.
The scapula or shoulder blade is a flat bone and very difficult to break. The mechanism is usually a direct blow. Any scapula fracture needs to be evaluated for related injuries.
Broken bones hurt. The lining of the bone (periosteum) is rich with nerve endings that can cause pain when inflamed; and the muscles surrounding the fracture go into spasm to prevent movement of the fracture site, and this spasm may intensify the pain.
Bones have a rich blood supply and will bleed when injured. This will cause swelling and the blood that seeps into the surrounding tissue will also cause further pain. The discoloration due to the blood can show up as dark red or purple bruise in the area of the fracture site.
Because muscles and tendons may not be damaged, the person may be able to move the injured extremity. For that reason, just because you can move the injured area, doesn't mean it's not broken.
If there is damage to a nearby artery, the injury may be cool and pale (distal to the injury), and if there is nerve damage, there may be numbness (distally).
Most broken bones require medical care but the urgency of that care depends upon the type of fracture and the circumstances.
Fractures may be difficult to diagnose in children because bones have not completely formed. Many parts of developing bone are comprised mostly of cartilage and have yet to have calcium deposited in them. Growing bone also has growth plates that may mimic or hide fractures. On occasion, the diagnosis of a fracture is made clinically based upon physical exam, even if the X-rays do not show an injury.
The initial treatment of a fracture begins with stabilization and immobilization. In the field RICE (rest, ice, compression and elevation) may help make the patient more comfortable and prevent the fractured bones from moving. Often the pain associated with a fracture is due to spasm of the muscles surrounding the fracture site trying to prevent movement. Splinting may help relieve some of that pain. Depending upon the injury, EMS providers may consider traction to help with stabilization and pain control.
For non-open fractures, or other fractures that can be treated without emergency surgery, the goal is to immobilize the injury to maintain anatomic alignment to allow the bone to heal.
Bone heals in three stages.
In the emergency department, walk in clinic, or doctor's office, the extremity is usually splinted using a combination of soft padding, casting material (plaster, fiberglass), and ace wraps. This splint is not circumferential like a cast, because a fracture has the potential for swelling of the surrounding tissues, and if a tight cast were in place, that swelling could cause complications including significant pain and potential blood supply issues.
Once the patient is discharged, their instructions are to elevate the injury and ice the area, even with the splint, to help decrease swelling and inflammation.
After a few days, once the initial swelling has resolved, a circumferential cast may replace the splint and will be worn until the fracture is healed. The time frame for healing depends upon the type of fracture and its location. X-rays may be used to help determine when it is time for the cast to be removed.
Finger and hand fractures may be more complicated. The hand is a complex web of tendons, blood vessels, and nerves that allow fine motor function. What might be acceptable healing and alignment in an arm or leg may not be appropriate in a hand. Some finger injuries need nothing more than a metal splint or buddy taping one finger to another for support, while others will need surgery. The type of treatment will depend upon the type of injury.
Most toe injuries heal very well own and need nothing more than buddy taping one toe to another for support.
The treatment for rib fractures involves pain control so that the patient can take deep breaths and allow the lung to expand beneath the injury site to prevent pneumonia. Rib injuries are not wrapped or bandaged to help with pain control because this will limit their movement, and prevent lung expansion. Because of this, rib fractures generally take 4 to 6 weeks to heal and may cause pain throughout the healing process.
The decision to operate on a fracture depends upon the type of fracture, whether it can heal in good alignment on its own, and whether other potential complications exist.
Sometimes patients are taken to the operating room for a closed reduction (resetting of the bone) and splinting of the fracture. When a fracture is markedly displaced and misaligned, it may be too painful to move or manipulated the bone without an anesthetic.
If it appears that the fracture is unstable and cannot be held in place and in good alignment with just a splint or cast, an open reduction and internal fixation (ORIF) may be needed. An incision is made so that the bony pieces can be identified and aligned. Metal plates and screws, wires or rods may be used to stabilize the fracture. The hardware may be left in place forever or it may be there only temporarily until the fracture heals. Hip fractures almost always require ORIF to allow the patient to heal and regain the ability to walk.
Surgery may be required in situations where there is associated injury to arteries and nerves and they need to be repaired or decompressed.
Open fractures often have to go to the operating room to be washed out to prevent infection of the bone (osteomyelitis).
Many broken bones occur because of accidents in the home, at work or at play, and not all may be preventable. Using proper safety equipment and precautions may minimize the risk of injury, but it cannot be completely eliminated.
As we age, there is an increased risk for falls at homes and some preventive steps may help reduce fall risks. These include:
Bones also get old as we age and the management of osteoporosis is a life-long commitment. Increasing calcium content in bone will decrease the risk of spontaneous fracture, and also may make bone strong enough to potentially withstand an injury that otherwise would result in a fracture. Ways to prevent osteoporosis include:
Fractures are a common injury, but the prognosis depends upon the bone that is broken, the location of the break, whether any complications exist and the underlying medical condition of the individual. Most arm and leg fractures heal well, and the goal is for the person to return to their baseline level of activity.
Doctors, pharmacists, and other health-care professionals use abbreviations, acronyms, and other terminology for instructions and information in regard to a patient's health condition, prescription drugs they are to take, or medical procedures that have been ordered. There is no approved this list of common medical abbreviations, acronyms, and terminology used by doctors and other health- care professionals. You can use this list of medical abbreviations and acronyms written by our doctors the next time you can't understand what is on your prescription package, blood test results, or medical procedure orders. Examples include:
CT scan (computerized tomography) is a procedure that uses X-rays to scan and take images of cross-sections of parts of the body. CT scan can help diagnose broken bones, tumors or lesions in areas of the body, blood clots in the brain, legs, and lung, and lung infections or diseases like pneumonia or emphysema.
MRI (magnetic resonance imaging) is a procedure that uses strong magnetic fields and radiofrequency energy to make images of parts of the body, particularly, the organs and soft tissues like tendons and cartilage.
Both CT and MRI are painless, however, MRI can be more bothersome to some individuals who are claustrophobic, or suffer from anxiety or panic disorders due to the enclosed space and noise the machine makes.
MRI costs more than CT, while CT is a quicker and more comfortable test for the patient.
X-rays are a powerful form of electromagnetic radiation that has the ability to pass through solid objects. In medicine, X-rays are used to obtain an image of a part of the body. X-rays are necessary to diagnose many illnesses, for example, tumors, arthritis, dental problems, digestive or heart problems, and bone fractures.
The side effects, dangers, and risks of having X-rays while pregnant or breastfeeding are provided.
