There are three steps in fracture healing:

1.Inflammation

2.Repair

3.Remodeling

1.Inflammation: Hematones appear at the site and forms hemotocytes. Granula tissue formation.

2. Repair:  a).soft callus: At the site of fracture a cartilage forms which serves as a bridging bone.

                 b).hard callus: the callus is replaced by the immature bone.

3. Remodeling: The osteoblats forms the site and replaces the immature with the hard bone.


 

 

If it's not clear what level of care is needed, try to judge the extent of tissue damage, based on the following burn categories:

1st-degree burn

A first-degree burn is the least serious type, involving only the outer layer of skin. It may cause:

  • Redness
  • Swelling
  • Pain

You can usually treat a first-degree burn as a minor burn. If it involves much of the hands, feet, face, groin, buttocks or a major joint, seek emergency medical attention.

2nd-degree burn

Vitamin-D or 'sunshine mineral' is synthesized by the Integumentary system of the human body.

To make Vitamin-D the skin contians a cholesterol pigment Provitamin D3, which when reacts with Ultraviolet in the sunrays forms Vitamin D3.

From there, the body takes over, first passing the vitamin D through the liver and then through the kidneys, converting it along the way into the form that the body needs.

For minor burns:

  • Cool the burn to help soothe the pain. Hold the burned area under cool (not cold) running water for 10 to 15 minutes or until the pain eases. Or apply a clean towel dampened with cool tap water.
  • Remove rings or other tight items from the burned area.Try to do this quickly and gently, before the area swells.
  • Don't break small blisters (no bigger than your little fingernail). If blisters break, gently clean the area with mild soap and water, apply an antibiotic ointment, and cover it with a nonstick gauze bandage.
  • Apply moisturizer, aloe vera lotion or gel, or low-dose hydrocortisone cream, which may provide relief in some cases.
  • If needed, take an over-the-counter pain reliever, such as ibuprofen (Advil, Motrin IB, others), naproxen sodium (Aleve) or acetaminophen (Tylenol, others).
  • Consider a tetanus shot. Make sure that your tetanus booster is up to date. Doctors recommend people get a tetanus shot at least every 10 years.
  • See your doctor if you develop large blisters.
