Prolonged pressure on a particular skin region results in the breakdown and wound or ulcer formation. Such chronic ulcers are commonly seen in spine injuries when the patient is unable to move on his own. Areas of bony prominence like lower back (Sacrum, ischium), upper outer thigh region (trochanter), etc. are involved. Reconstructive plastic surgery by skin grafting or skin flaps is done.

Results of the surgery:

Surgery is done to remove all the dead tissues and resurface the raw area with good quality skin cover. Majority of ulcers heal after the surgery. Recurrence of lesion is there if effective measures are not taken to prevent prolonged presure.
