Fracture (Bone fracture) : Information

Introduction : Fracture (Bone fracture)

Fracture is a medical condition which leads to break in the continuity of the bone. A bone fracture can be the result due to high force impact or stress, or trivial injury as a result of certain medical conditions that weaken the bones, such as osteoporosis
, bone cancer, or osteogenesis imperfecta, where the fracture is then properly termed a pathologic fracture.

Classification:

By Cause:

  • Traumatic fracture - This is a fracture due to trauma. e.g.- Fractures caused by a fall, road traffic accident, fight and many others
  • Pathological fracture - A fracture of bone due to certain disease that has made bone weak is called pathological fracture. e.g.- a fracture through a bone weakened by metastasis. Osteoporosis is the most common cause of pathological fracture.

All fractures can be broadly described as:

  • Closed (simple) fractures: Are those in which the skin is intact
  • Open (compound) fractures: Involve wounds that communicate with the fracture, and may thus expose bone to contamination. Open injuries carry a higher risk of infection.

Other types of fracture are:

  • Complete fracture: A fracture in which bone fragments separate completely.
  • Incomplete fracture: A fracture in which the bone fragments are still partially joined. In such cases, there is a crack in the osseous tissue that does not completely traverse the width of the bone.
  • Linear fracture: A fracture that is parallel to the bone's long axis.
  • Transverse fracture: A fracture that is at a right angle to the bone's long axis.
  • Oblique fracture: A fracture that is diagonal to a bone's long axis.
  • Spiral fracture: A fracture where at least one part of the bone has been twisted.
  • Comminuted fracture: A fracture in which the bone has broken into several pieces.
  • Impacted fracture: A fracture caused when bone fragments are driven into each other.
  • Avulsion fracture: A fracture where a fragment of bone is separated from the main mass.

Symptoms : Fracture (Bone fracture)

Fractures can cause

  • Pain and bleeding
  • Swelling
  • Bruising or discolored skin around the affected area
  • The patient is unable to put weight on the injured area
  • The patient cannot move the affected area
If it is an open fracture t here may be: Bleeding Damage to adjacent structures such as nerves or vessels, spinal cord and nerve roots (for spine fractures), or cranial contents (for skull fractures) can cause other specific signs and symptoms.

Causes : Fracture (Bone fracture)

The fractures are generally caused due to fall with a great impact or road accident. Healthy bones are extremely tough and resilient and can withstand powerful impacts. When people enter old age two factors make their risk of fractures greater; weaker bones and a greater risk of falling. Children are physically more active than adults, thus they are more prone to accidents or fall that may result in fractures. People with debilitating illnesses and conditions that may weaken their bones also have a higher risk of fractures. Examples include osteoporosis, infection or a tumor.

Diagnosis : Fracture (Bone fracture)

A fractured bone can be diagnosed clinically based on the history and the physical examination of the patient. Imaging by X-ray is often performed to view the bone suspected of being fractured. In certain suitations, x-ray alone is not sufficient, a computed tomograph (CT scan) or MRI may be performed. Reference: http://orthoinfo.aaos.org/topic.cfm topic=A00139

Prevention : Fracture (Bone fracture)

Nutrition and sunlight - The human body needs adequate supplies of calcium for healthy bones. Milk, cheese, yoghurt and dark green leafy vegetables are good sources of calcium. Our body also needs vitamin D to absorb calcium. By exposing to sunlight, as well as eating eggs and oily fish are good ways of getting vitamin D. Physical activity - The more weight-bearing exercises the person does, the stronger and denser their bones will be. Examples include skipping, walking, running, and dancing any exercise where the body pulls on the skeleton. Older age not only results in weaker bones, but often in less physical activity, which further increases the risk of even weaker bones. It is important for people of all ages to stay physically active. The (female) menopause - Hormones estrogen, which regulates a woman's calcium, starts to drop and continues to do so until after the menopause. In other words, calcium regulation is much more difficult after the menopause. Consequently, women need to be especially careful about the density and strength of their bones during and after the menopause.
