- Surgical: clean-cut edges from sharp objects (e.g., scalpel blade).
- Laceration: uneven, jagged edges (like from barbed wire).
- Abrasion: superficial wound damaging the epithelial layer.
- Puncture: small external wound that may penetrate deep tissue.
- Avulsion: wound with a skin flap.
Closed Wounds include:
- Fracture: break in bone.
- Rupture: internal organ injury causing internal bleeding.
- Contusion: trauma rupturing capillaries (bruise).
- Haematoma: pocket of collected blood.
Degree of Contamination:
- Clean: surgical wound made under aseptic conditions.
- Clean-Contaminated: surgical wound with mild contamination.
