Injuries sustained due to road traffic accidents or run over injuries lead to separation of overlying skin from underlying muscles which need to be reconstructed by Skin grafting or flap surgery.
When there is loss of skin or tissues over the lower limb following trauma, the resultant defect can be reconstructed by plastic surgical means by using muscle and or skin from other part of the body (flap surgery)
Destruction of lymphatic channels i.e. vessels which carry lymph from the leg towards the heart can lead to swelling of one or both lower limbs which eventually predisposes the leg to recurrent ulcerations. Using plastic surgery, the swelling can be reduced by excision of excess tissue or by creating a bypass route for the lymph flow.
