Study Notes

Introduction

Trauma is a leading cause of death and disability in individuals aged 1 to 44 years.
Understanding trauma mechanics and biomechanics is crucial in patient analysis and management.
Accurate documentation is essential for physicians to understand trauma events.

Trauma, Energy, and Kinetics

Trauma results from external energy exceeding the body's capacity to sustain and dissipate it.
Different energy types (mechanical, chemical, thermal, electrical, barometric) cause distinct trauma types.
Mechanical energy includes kinetic (motion) and potential (stored) energy.
Biomechanics is the study of living organisms' physiology and mechanics.
Kinetics analyzes the relationships between speed, mass, force direction, and resulting injuries.
The body's ability to disperse delivered energy influences the sustained injury.
External factors like force, size, velocity, acceleration, and affected body area determine injury type.
