Chronic wounds can start as acute wounds, which are injuries that happen rapidly. A few examples are abrasions, puncture wounds, and burns. Typically, these wounds will heal on their own or with minimal treatment; if they don’t, they become chronic wounds.
A few specific types of chronic wounds are:
- Post-traumatic non-healing wounds
- Post-operative non-healing wounds
- Venous ulcers
- Burn wounds
- Pressure ulcers
- Diabetic ulcers
Chronic wounds are wounds that show no signs of healing within 2-3 weeks of their appearance. A wound can become chronic from insufficient blood supply, too much pressure on the affected area, or bacteria exposure.
