Orthopedic Injuries

Causes of Orthopedic Injuries

  • Most orthopedic injuries can occur through several mechanisms:

    • Sporting Events and Athletic Contests: Common scenarios where injuries occur.

    • Motor Vehicle Accidents: High-speed impacts leading to significant injuries.

    • Falls: Everyday occurrences that often lead to injuries, particularly in the elderly.

    • Assaults: Physical altercations that may cause blunt force trauma.

Mechanisms of Injury

  • Injuries can be categorized based on the mechanism:

    • Direct Blows: Direct trauma applied to a body part.

    • Indirect Forces: Impact forces that do not directly strike the injury site.

      • Example: Falling on an outstretched arm may fracture the wrist without direct trauma to the elbow.

    • Twisting Forces: Injuries resulting from rotational movements.

      • Example: Twisting an ankle while landing incorrectly.

    • High Energy and High MOI (Mechanism of Injury) Events: Events with significant force, like high-speed car crashes.

Types of Fractures

  • Definition of Fracture: A broken bone.

  • Classification of Fractures:

    • Closed Fractures: No open wound; the skin is intact.

    • Open Fractures: The fractured bone protrudes through the skin, creating a wound.

    • Nondisplaced Fractures: The bone is fractured at one site but remains in alignment.

    • Displaced Fractures: The bone is fractured and misaligned, often showing visible deformities or shortening.

Dislocations

  • Definition: When bone ends at a joint lose contact.

  • Common Sites of Dislocation:

    • Shoulder

    • Elbow

    • Hip

    • Knee

    • Fingers

  • Reduction of Dislocation:

    • The process of restoring the joint to its normal anatomical position, either spontaneously or via external force.

Sprains and Strains

  • Sprains: Injury to a joint caused by overstretching or tearing ligaments.

  • Strains: Injury affecting muscles or tendons, caused by overstretching or tearing.

  • Key Differences:

    • Sprain = Joint

    • Strain = Muscle/Tendon

Categorization of Injuries

  • Minor Injuries:

    • Minor strains and sprains, small fractures (e.g., fingers or toes).

  • Moderate Injuries:

    • Non-displaced fractures of long bones.

  • Severe Injuries:

    • Displaced fractures, open fractures, amputations, and bilateral femur fractures.

Overview of Splints

  • Types of Splints:

    • Rigid Splints: Standard padded board splints used for immobilizing fractures; ideal for leg injuries.

      • Example: Padded boards and cravats for standard limb support.

    • Formed Splints: Malleable splints like the Sam splint, which can be molded to the injury's shape.

Additional Stabilization Techniques

  • Sling and Swath: Used to stabilize shoulder and upper arm injuries; the sling supports the arm while the swath wraps around the body for added stability.

  • Pelvic Binder: Designed to stabilize the pelvis in pelvic fractures to limit potential hemorrhage.

  • Traction Splint: Specifically for mid-shaft femur fractures; it pulls the bone and realigns it to minimize pain and stabilize the fracture.
