Injury are damaged tissues or organs which occur when it encounters trauma or physical force that is greater than what it can resist or absorb
Factors affecting the ability of the tissues and organs to effectively resist or absorb forces: Inherentabnormality, Age, Technique, Fitness Level, Equipment, and Environmental Aspects
TensileForces that act away from the centre of the structure, causing to pull or stretch
Compressive Forces are forces that gives impact to the center of the body causing it to bend or fold
Shear Forces are opposing forces toward the different ends of the structure causing it to twist
What are the Direction of Forces?
Tensile Forces
Compressive Forces
Shear Forces
Sprain are overstretched ligaments, causing a partial tear in the ligament
The Ligaments stabilized and limits mobility of the joints
Strain are the overused muscles
Strain is a non contact injury that results from over contractions
Anterior Cruciate Ligament is a connective tissue that helps stabilize the knee every time the muscle contracts.
Fracture is a broken bone
What are the different kinds of fracture?
SimpleFracture
CompoundFracture
GreenstickFracture
ComminutedFracture
Compound fracture are also known as open fractures
Comminuted fracture is where the bone breaks into three or more pieces
Greenstick fracture occurs when bones bend but not break
simple fracture refers to a break that does not compromise the skin
Bones break as a result of force or trauma
Fractures can be also caused by less traumatic but repeated force
Compound fracture is a fracture that breaks the bone through the skin, or a wound leads to the fracture site, causing the broken ends of bone to come into contact with the outside environment
Simple fracture is also known as closedfracture
Dislocation is the bone pushed out of the proper alignment
Dislocation causes deformity
The pain of dislocation will be relieved once the bone is repositioned
Concussion are life threatening injuries because they disrupt the normal function of the brain
what are thee common signs of concussion?
nausea
dizziness
headaches
confusion
light sensitivity
Stress Fracture is a tiny crack in the bone
Stress fracture is a small crack in the bone that occurs when the bone is repeatedly overused.
Stress fracture occurs when repetitiveworkloadcreatesmicrotrauma - as thick as the strand of hair - inthebone and getsbiggerovertime
Tendinopathy occurs due to muscle imbalance between muscle pairs
Bursitis: inflammation of a bursa that interrupts the surrounding structure, causing pain during movement
First aid is any care given to an injured or ill person before professional medical assistance arrives on the scene to take control of the situation
Why do we do bandaging?
to create pressure over an area;
to support and protect wound from contamination;
to reduce bleeding;
to secure a splint or dressing
What are the head and spine injuries?
headinjury
concussion
spinal injury
Bones, joints and muscle injuries: strain,sprain,fracture,dislocation
How to treat bones, joints and muscle injuries?
use the RICEmethod:Rest, Immobilize, Cold, Elevate
Fainting is a partial or complete loss of consciousness resulting from a temporary reduction of blood flow of the brain
What are the causes of fainting?
anemotionally stressful event
pain
heart dusease
overexertion
pregnant women and elderly
what is the first aid management when the victim faints?
Positionthevictimonhis or herback
keepthevictim in a lying position
loosenanyrestrictiveclothing, such as tie or buttoned-up collar
