Injuries

• Hard tissue injuries include fractures and dislocations.
• An injury is damage to a biological organism.
• Soft tissue injuries include damage to muscles, ligaments, tendons, and cartilage.
• Acute injuries can be further classified as hard tissue injuries or soft tissue injuries.
• Injuries can be classified as acute/accidental injuries or chronic injuries.
• A sprain is an over-stretch or tear in a ligament.
• Acute/Accidental Injuries


  an injury that happens suddenly
• Chronic Injuries


  injuries that are caused over time and are caused by repeated blows, overstretching, repeated friction, overuse
• A sprain is an over-stretch or tear in a ligament.
• A strain is an over-stretch or tear in a muscle or tendon.
• Chronic injuries are injuries that develop over time and are often caused by repetitive movements or overuse of a particular body part.
• A contusion is a bruise caused by a direct blow to the body.
• Abrasions


  an acute injury where tissues are injured by friction
• Acute injuries can be further classified as hard tissue injuries or soft tissue injuries.
• Fractures and dislocations are examples of hard tissue injuries.
• A dislocation occurs when the bones in a joint are forced out of their normal positions.
• Abrasions are acute injuries where tissues are injured by friction.
• Contusions


  an acute injury where bruises are developed by a direct blow
• Lacerations


  an acute injury, jagged cuts
• Punctures


  an acute injury cause by narrow stab wounds
• Avulsions


  complete tissue tears
• Lacerations are acute injuries where the skin is torn or cut.
• Punctures are acute injuries caused by narrow stab wounds.
• Contusions are acute injuries where bruises are developed by a direct blow to the body.
• Acute hard tissue injuries are injuries to bones
• Fracture

  a fracture is a break or crack in a bone
• There are 2 types of fractures


  Simple closed fracture

  Compound open fracture
• Dislocations


  where a bone is forced out of its normal position
• Acute soft tissue injuries are damage to muscles, ligaments, tendons and cartilage
• Ligaments are bonds of tissue which join bones together
• Tendons are tissue that attaches muscle to bone
• Cartilage is strong tissue that protects joints and bones
• When soft tissues are injured, it becomes inflamed
• Chronic muscle strain


  chronic injury which is the result of repetitive movement
• Tendonitis


  chronic injury

  inflammation of a tendon
• Osteoarthritis: degenerative joint disease where, in which the tissues in the joint break down over time
• Stress fractures


  chronic injury

  tiny cracks in a bone
