The orthopedic reconstruction
requires not only surgery of the bone
but also surgery for associated injuries to nerves , blood supply,
and reconstruction of lost skin.
With increasing road accidents ,
the severity of injury has extended as well .
The injury is not confined to bone,
but the skin is also lost .
Sometimes the blood supply is lost as well in the accident.
If the blood supply is not restored within hours , the part can die.
For early healing and optimum return of function,
it is important to restore the skin at the earliest.
This requires skin cover called flaps.
