Injury refers to the damage inflicted on any part of the body due to deliberate or accidental application of mechanical or other traumatic agent
A wound is the disruption of the continuity of tissues and lining epithelium produced by external mechanical force

Cases that should be labelled as medico-legal may include:
Road side accidents, factory accidents, or any other unnatural mishaps

Blunt force injuries result from forceful contact with a blunt object, such as fists, baseball bat, hammer, walls, trees, etc.
The three main types of blunt force injuries include:
Abrasions
Contusions
Lacerations
Abrasions are also known as scrapes, scratches or grazes. They refer to a superficial injury involving only the outer layers of the skin; they do not penetrate the full thickness of the epidermis.
Brush abrasions are broad patches, commonly seen as road rash following a motor vehicular accident
A scratch is a linear abrasion produced by drawing a sharp point over the surface of the skin or mucous membrane
A contusion is also known as bruise of ecchymosis, refers to discoloration resulting from hemorrhage beneath the skin, tissue or mucosa without any associated breach in the surface.
Post-mortem lividity may be confused by bruising
Various terms exist to describe the gross appearance of contusions, including petechiae, ecchymosis, and hematoma
Lacerations refer to splitting of tissues and the forceful tearing of skin when an object impacts skin with a force that exceeds its elastic capacity.
Lacerations have ragged wounds with irregular division of tissue planes
Their margins are often bruised and abraded
Blood vessels, nerves, and delicate tissue bridges may be exposed in the depth of the wounds
Lacerations do not generally reflect the shape or size of the object that produced them
Sharp force injuries refer to damage to tissues or organs by objects or weapons with sharp edges or pointed ends, classified into incised, stab, and chop wounds
Incised wounds are most often caused by an object moving in a slashing motion, resulting in clean edges, minimum bruising, and no bridging of nerves or vessels
Stab wounds are the result of a pointed or sharp object forced inward, usually caused by a weapon being thrust at or into a victim
Chop wounds are caused by objects with relatively sharp edges and reasonable weight, resulting in a combination of sharp and blunt injuries at the point of impact
Defensive wounds refer to injuries sustained by victims attempting to defend themselves from attack, often found on the victim's fingers, arms, forearms, and upper arms
