Lecture 4: Kinematics of trauma and fracture

Question 1

What are the 4 ways injuries occur?

Answer 1

1) MOI
2) IOS
3) types of energy
4) law of conservation of energy

Question 2

What is the def of MOI

Answer 2

THE METHOD BY WHICH DAMAGE (TRAUMA) TO SKIN, MUSCLES,

ORGANS, AND BONES OCCURS.

Question 3

What does the MOI describe?

Answer 3

DESCRIBES THE FORCES ACTING ON THE BODY THAT CAUSED THE
INJURY
(the how, with what force, what body part)

Question 4

Why is mecaanism of injury so important?

Answer 4

• HCP USE M.O.I. TO HELP DETERMINE HOW LIKELY IT IS THAT A SERIOUS
INJURY HAS OCCURRED.

THE REPORTED MECHANISM MAY INDICATE THE INJURIES ATHLETIC THERAPISTS/FIRST AIDER CAN EXPECT TO FIND UPON THEIR ARRIVAL.

Question 5

true of false: MOI will not help you find your IOS?

Answer 5

FALSE

Question 6

What is the definition of index of suspician?

Answer 6

EDUCATED IDEA ON THE POSSIBLE INJURY THAT HAS OCCURRED

YOUR CONCERN FOR POTENTIALLY SERIOUS UNDERLYING INJURIES

Question 7

What are the 2 types of indices of suspicion and what they mean>

Answer 7

A “HIGH INDEX OF SUSPICION” MEANS YOU CONSIDER THE DIAGNOSIS A STRONG POSSIBILITY

A LOW INDEX OF SUSPICION MEANS THE INVERSE

Question 8

What are some different examples of MOI?

Answer 8

Contact vs non contact
Valgus/varus force
Sharp deceleration
FOOSH
Hyperextension/hyperflexion
Invresion/eversion
Collision

Question 9

What are some examples of indez of suspicion

Answer 9

Contusion
Ligament sprain Gr I.II.III
Complete tear
Dislocation / fracture
Sprain/strain/dislocation
Ligament sprain Gr I.II.III
contusion/laceration/int.bleed

Question 10

What are the 3 types of energy

Answer 10

Potential
Kinetic
Work

Question 11

Explain the concept of inertia

Answer 11

A body in motion will remain in motion unless acted upon by an outside force
same for rest

Question 12

Explain potential energy

Answer 12

product of mass, force of grav and height

Question 13

Explain kinetic energy

Answer 13

eneryg in motion

energy of a moving object

Question 14

Explain work energy

Answer 14

kinetic energy is converted to work when bringing an object to stop

Question 15

What is the greatest determination of kinetic energy

Answer 15

speed

Question 16

True of false: if you have double the mass , its double the injury>

Answer 16

TRUE

Question 17

True or false and explain

Double speed=double energy>?

Answer 17

FALSE

Double speed=quadruple energy

Question 18

What is the definition of. trauma

Answer 18

DEFINED AS INJURY TO HUMAN TISSUES AND ORGANS RESULTING FROM THE TRANSFER OF ENERGY FROM THE ENVIRONMENT

Question 19

What are the 2 types of trauma>

Answer 19

blunt trauma

penetrating trauma

Question 20

Give the definition of blunt trauma and explain it

Answer 20

Result of force to the body that causes injury primarily without penetrating the soft tissue or internal organs and cavities (- Transmission of Energy into the body)

causes:
Closed injury
Indirect injury to underlying structures

Question 21

What is an injury in sport caused by and how can it be prevented?

Answer 21

extreme exertion
fatigue
direct trauma

PROTECTIVE GEAR CAN REDUCE

Question 22

What are the most common injuries for in an athletic setting (6)

Answer 22

CONTUSIONS
• LIGAMENTOUS INJURIES
• FRACTURES
• DISLOCATIONS
• SPINAL INJURIES
• INTERNAL ORGAN INJURIES (CONTACT SPORTS)

Question 23

What is the definition of penetrating trauma?

Answer 23

Injury by objects that primarily pierce and penetrate the surface of the body and cause damage to soft tissues, internal organs and cavities

Question 24

What is peenetrating trauma in sports caused by and what type of injury results from it

Answer 24

CAUSED BY SHARP OBJECTS (EX: BROKEN SPORT EQUIPMENT)

• OPEN INJURY
• DIRECT INJURY TO UNDERLYING STRUCTURES

Question 25

What are the 6 predictors of sport related injury

Answer 25

1) kinematics aand force involved
2) sped
3) equipment contributing to the injury
4) involvment of protective equipment
5) nature of the sport
6) skill level
