Accident vs. Injury1. Accident: unexpected, unavoidable and unintentional eventC. Historical Perspective1. Treatment of injuries are as old as them2. Surgical instruments by Indian, Egyptians, Incas, etcD. Why Study the Biomechanics of Injuries?1. National Safety Council: Annual cost > %435 million and 40% of hospital admissions2. Unintentional injuries are 5th leading cause of death in U.S3. Helps understand forces behind injuries and tissue damagedE. Types of Injuries 1. Macrotraumatica. Result of trauma, produce immediate pain and disabilityb. Include fractures, dislocations, subluxations, sprains, strains and contusions2. Microtraumatica. Often called overuse injuries — result of repetitive loading or incorrect mechanics- ex: tendonitis, bursitis, etc3. Secondarya. inflammatory or hypoxia resulting from primary injuryF. Injury Classification1. Acute: injury that has just occurred or is only a few days old2. Chronic: injury lasting several weeksG. Sprain1. Injury to a ligament2. Pain-disability3. Joint disability4. ClassificationH. Strain1. Injury to a muscle2. ClassificationI. Inflammation1. Immune response to bodily injury2. Not an infection3. Cardinal signs:a. Rednessb. Heatc. Swellingd. Paine. Loss of functionJ. Contusion1. Bruise: localized bleeding under the skin2. Causesa. direct blowb. tearing tissueK. Fracture1. Break of a bonea. ex: stress, avulsion, closed, openL. Dislocation1. Temporary movement of a bone from its original position2. Direct force or extreme movement beyond ROMM. Healing Continuum1. Phase 1: Inflammatory-Response (within days)2. Phase 2: Fibroblastic-Repair (within weeks)3. Phase 3: Maturation-Remodeling (within years)N. First Aid/Treatments1. PRICEa. Protectionb. Restc. Iced. Compressione.
