PAPER 1 > INJURY PREVENTION AND THE REHABILITATION OF INJURY Flashcards
ACUTE INJURIES
a sudden injury associated with a traumatic event
CHRONIC INJURIES
a slowly developed injury associated with over use
HARD TISSUE INJURY
damage to the bone, joint or cartilage including fractures and dislocations
SOFT TISSUE INJURY
damage to the skin, muscle, tendon or ligament including tears, strains and sprains
FRACTURE
a partial or complete break in a bone due to an excessive force that overcomes the bones potential to flex
COMPOUND FRACTURES OPEN OR CLOSED?
open fractures
SIMPLE FRACTURES OPEN OR CLOSED?
closed fractures
COMPOUND OPEN FRACTURES
the fractured bones themselves break through the skin, creating an open wound with a high risk of infection
SIMPLE CLOSED FRACTURES
the skin remains unbroken as the fracture causes little movement of the bone and therefore minimises the damage to the soft tissue surrounding it
HARD TISSUE INJURIES RESULT (4)
> internal bleeding
circulatory problems
joint instability
usually require hospital treatment
SOFT TISSUE INJURIES RESULT (4)
> inflammation
bruising
internal bleeding
require immediate attention to minimise recovery period
ACUTE INJURY EXAMPLE
fracture of a bone in a boxer’s jaw
COMMON CAUSES OF ACUTE INJURIES (3)
> collision between two players
falls
excessive impact from an object
CHRONIC INJURY EXAMPLE
tennis elbow
COMMON CAUSES OF CHRONIC INJURIES (9)
> overuse
sudden increase in intensity of activity
sudden increase in frequency of activity
sudden increase in duration of activity
reduction in recovery
inadequate equipment
poor technique
poor range of motion
inadequate warm up
COMMON INDICATIONS OF A FRACTURE (6)
> pain at the fracture site > inability to move joint > unnatural movement around the injured area > deformity > swelling > discoloration
COMMON CAUSES OF FRACTURES (2)
> direct force (collision or object)
> indirect force (falling or poor technique)
INCOMPLETE FRACTURE
a partial crack in the bone that doesn’t completely separate the bone
COMPLETE FRACTURE
a total break in the bone which separates the bone into one or more fragments
GREENSTICK FRACTURE
a splitting partial break in the bone resulting from a bending action
TRANSVERSE/OBLIQUE/SPIRAL FRACTURES
a crack perpendicular, diagonal or twisting diagonal respectively across the length of the bone
COMMINUTED FRACTURE
a crack producing multiple fragments of bone and a long recovery process
IMPACTED FRACTURE
a break caused by the ends of the bone being compressed together
AVULSION FRACTURE
a bone fragment detached at the site of connective tissue attachment
DISLOCATION
the displacement of one bone from another out of their original placement
COMMON CAUSES OF DISLOCATIONS (2)
> direct force (collision or object)
> indirect force (fall)
DISLOCATIONS CAUSE THE JOINT TO
push past its extreme range of motion
TYPICAL SITES FOR DISLOCATIONS (7)
> shoulder > hip > knee > ankle > elbow > fingers > toes
COMMON INDICATIONS OF A DISLOCATION (5)
> severe pain at the injury site > loss of movement > deformity > swelling > 'pop' feeling
DISLOCATION REQUIREMENTS
medical specialist treatment to put back into place and to ensure the joint is put back in the correct alignment without causing further damage
SUBLAXATION
an incomplete or partial dislocation
SUBLAXATION DAMAGE
often causes damage to the ligaments that connect bone to bone
SUBLAXATION OVERSTRETCH
ligaments can permanently lengthen which decreases joint stability and increases the likelihood of recurrent dislocations
RESULT OF OVERSTRETCH SUBLAXATION AND DISLOCATIONS
result in surgeries and compromise a long term playing career
RUPTURE
a complete tear of a muscle, tendon or ligament
HAEMATOMA
localised congealed bleeding from the ruptured blood vessels
CONTUSION IS ALSO KNOWN AS A
bruise
CONTUSION
a bruise in an area of skin or tissue which the blood vessels have ruptured (torn)
MINOR CONTUSIONS
heal quickly by themselves without the athlete having to have a break in lay or training
SEVERE CONTUSIONS
can cause deep tissue damage and therefore prevent participation in sport for months
SPRAIN
overstretch or a tear in the ligament that connects bone to bone
COMMON CAUSES OF SPRAINS (4)
> sudden impact
sudden twist
sudden fall
forcing the joint beyond its extreme range of motion
COMMON SITES FOR SPRAINS (2)
> ankles
knees
thumbs
COMMON INDICATORS OF A SPRAIN (5)
> pain > swelling > bruising > inability to bear weight > possible dislocation
4 DIFFERENT SEVERITY’S OF SPRAINS
> first degree sprain
second degree sprain
tear
third degree sprain
FIRST DEGREE SPRAIN
overstretching a few ligament fibres
SECOND DEGREE SPRAIN
partial tear of ligament fibres
TEAR
a total rupture
THIRD DEGREE SPRAIN
detachment of a ligament from the bone
STRAIN
overstretch or tear in the muscle or tendon that connects muscle to bone
COMMON CAUSES OF A STRAIN (3)
> overstretching a particular area
contracting muscle fibres too quickly resulting in an overstretch
partial or complete rupture of the muscle fibres and tendons
MOST COMMON SPORTS FOR STRAINS (3)
> dynamic lunging (badminton)
sprinting out of a block (track sprinting)
contact activities (tackles in rugby/football)
COMMON INDICATORS OF A STRAIN
> pain on movement
swelling
discoloration
bruising
