Fracture Skull

 

• Most fragile bone in the skull to get fractured is–temporal.

   1. Linear or fissured fractures:

    • MC type of skull fracture or cracks in the bone, involving entire thickness of bone, or outer or inner table only.

 2. Depressed fracture is also called Signature fracture.

    • Localized depressed fracture is caused by blows from heavy weapon with a small striking surface e.g. stone, stick, axe, hammer, etc.

    • The outer table is driven into the diploe, inner table is fractured irregularly.

 3. Pond or indented fractures: They occur only in skulls, which are elastic, i.e. the skulls of infants.

 4. Gutter fractures: They are formed when part of the thickness of the bone is removed so as to form a gutter e.g. oblique bullet wound.

The extent of the surface

    • The estimation of the surface area of the body involved is worked out by the ‘rule of nine’ by Wallace*.

    • Rule of Palm: In case of patchy burns, rule of ‘9’ is of less value. Palm of an individual is    1% of the Body Surface Area.

    • Minimum 1/3rd area must be involved to label it grevious*.

    • Involvement of 50% of burn proves fatal, even of first degree.

Parkland formula is used to calculate the fluid to be given in the first 24 hours.
