Acute wounds: Sudden injuries like cuts, lacerations, abrasions, and surgical incisions. They typically heal in a predictable sequence with proper care.

Chronic wounds: Wounds that fail to progress through normal healing (last >4–6 weeks), including diabetic foot ulcers, venous leg ulcers, and pressure injuries. Require specialized management and often advanced dressings.

Traumatic wounds: Caused by external force—punctures, crush injuries, burns, and avulsions. Risk of contamination and tissue loss; may need debridement and reconstruction.

Surgical wounds: Intentional incisions closed during procedures. Can be uncomplicated or develop complications such as infection, dehiscence, or seroma.

Burns: Thermal, chemical, electrical, or radiation injuries classified by depth (superficial, partial-thickness, full-thickness). Depth and area determine treatment and scarring risk.

Pressure injuries: Localized damage from prolonged pressure, typically over bony prominences. Staged I–IV by severity; prevention and offloading are critical.

Infected wounds: Any wound with bacterial invasion causing purulence, increased pain, redness, swelling, or systemic signs. Prompt infection control is essential.

Ischemic wounds: Result from poor blood flow (arterial disease), often painful and slow to heal; revascularization may be needed.

Combined wounds: Many patients have overlapping causes (e.g., diabetic patient with a neuropathic ulcer plus infection), requiring a multimodal approach.
