ACUTE WOUNDS
Compartment syndrome is a medical condition in which there is elevated pressure in one of the body’s compartments. This leads to insufficient blood supply to tissues in that area. Fasciotomy can be performed if pressures are raised above 30 mmHg. Also, high pressure injection injuries are mentioned here.

CHRONIC WOUNDS
Chronic wounds are the ones which fail to heal in expected time for a particular wound. Leg ulcers and pressure sores fall under this category. Pressure sores are classified into four types. In the end, light has been shed on the vacuum assisted closure.

TISSUE INFECTIONS AND SCARS
The necrotizing soft tissue infections are rare but often fatal. Its types include gas gangrene along with the streptococcal gangrene and necrotizing fasciitis. On the other hand, the types of scars include atrophic, hypertrophic and keloid. The point where scars cross joints or flexion ceases, a tight web is formed. This is termed as contractures.
