Acute wounds usually heal primarily, or with support (e.g., wound closure strips). Smooth, clean wound edges heal and close without any complications.
• Puncture wounds
• Skin donor sites
• Post-operative wounds
A chronic wound is one which displays no signs of healing after a certain time despite causal treatment.Chronic wounds heal secondarily. The edges of the wound are usually jagged and/or tissue defects are present. The wound must heal upwards from the base, and only then can it close from the outside to the inside. Often, an underlying disease is partly responsible for the condition of a chronic wound, so it is essential to treat the illness at the same time as the wound.
A leg ulcer is an open wound on the lower leg, usually caused by an arterial and/or venous circulatory disturbance. It can often be a long-term condition.
Post-operative wounds can become chronic because of infection, excessive suture tension, wound healing impairments or the presence of foreign bodies in the wound area.
Decubitus ulcers, also known as pressure ulcers or bedsores, involve damage to the skin and the underlying tissue. Local pressure leads to insufficient blood supply to the area affected, which in turn causes damage to the skin or tissue.
Diabetic foot syndrome
Diabetic foot syndrome (DFS) is a term covering various clinical pictures, comprising an infection, ulceration and/or destruction of deep tissue, which occur in the lower extremities with varying degrees of severity. Usually, a neuropathological abnormality is causally involved.
