Scars and Abnormal Scarring
Hypertophic scars occur when there's excessive collagen deposition. It can sometimes grow beyond the margins of the original wound, leading to a Keloid scar. This is more common in Afro-Caribbean’s.
After severe burns, it's common for there to be Wound contracture. This is where the tissues are permanently tightened, therefore making join movement much harder or even impossible e.g. Dupuytren’s contracture.
