Injury Flashcards
What is an acute injury?
Injuries resulting from a sudden there and then, stress to the body
What is an example of a cause of an acute injury?
A big hit in rugby
What is a chronic injury?
Injuries resulting from continuous stress over time to the body and normally linked to over training.
What are soft tissue injuries?
Stress/damage to soft tissues eg ligaments, tendons, muscles, skin and internal organs.
What are hard tissue injuries?
Stress/damage to a hard tissue eg bone/joint/cartilage
What is normally more serious, hard or soft tissue injuries?
Hard
What are examples of acute soft tissue injuries?
Sprain Strain Exercise induced muscle damage (DOMS) Haematoma Cramp Abrasion Concussion
What are examples of acute hard tissue injuries?
Fracture
Dislocations
Torn cartilage
What are examples of chronic soft tissue injuries?
Tendinosis
Tennis elbow
Achillis tendinosis
Medial tibial stress syndrome (MTSS/shin splints)
What are examples of chronic hard tissue injuries?
Stress fracture
Osteoarthritis
What is a sprain?
Damage (stretch/tear/rupture) to a ligament
What causes a sprain?
Sudden twist/impact or fall moving the joint beyond it’s normal/extreme ROM. eg common at the ankle when turning
What is a strain?
Damage to a muscle/tendon
What causes a strain?
Overstretching a muscle/tendon.
eg common in adductors in lunging sports such as badminton
What are the symptoms of a sprain/strain?
Pain, inflammation, bleeding/bruising and less ability for weight bearing.
Symptoms are dependent on severity, categorised using a 3 grade system (grade 3 is most severe)
What is a haematoma?
A localised pocket of congealed/thickened blood
What causes a haematoma?
Impact/blow to the body causing the rupture of blood vessel leading to bleeding which congeals to form bruising (contusion)
What is a cramp?
An involuntary muscle contraction
What causes a cramp?
Low oxygen and increased dehydration lead to less sodium/salt leading to muscle fatigue and insufficient ATP for the muscle to release the muscle contraction.
What is an abrasion/friction injury?
Superficial damage to the skin
What causes an abrasion/friction injury?
Contact/friction with a playing surface or clothing/equipment rubbing on the body causing mainly minor friction burns eg friction from a slide tackle on astro-turf.
What is a concussion?
A brain injury causing a temporary/complete loss of consciousness and brain functioning.
What causes a concussion?
Direct impact to the head or whip lash movement of the head which shakes the brain inside the cranium eg in contact sports such as rugby and boxing.
What are the symptoms of concussion?
Nausea, headaches, shallow breathing, dizziness, loss of balance/memory.
One major impact to the head (rugby) or repeated smaller impacts (boxing)
What is a fracture?
Partial/complete break in a bones continuity
What causes a fracture?
Mostly due to direct impact from a blow/fall to a simple twist, sudden muscle contraction or repetitive abnormal stress
What are the symptoms of a fracture?
Pain, swelling, loss of movement, deformity/discolouration. Most common in contact sports eg rugby
What is a dislocation/subluxation?
Partial/complete displacement of one bone from another.
What causes a dislocation/subluxation?
Primarily due to a force causing the joint to go beyond its normal ROM eg impact from from opponent/fall
What are the symptoms of a dislocation/subluxation?
Deformity, tenderness, loss of limb function/movement, swelling, pop/pain, can cause a rupture of ligament/tendon.
Most common in fingers/shoulders
What is tendinosis?
Degeneration of a tendon.
What causes tendinosis?
Repetitive overuse, common at tendons of the ankle/heel, knee, shoulder, elbow and wrist.
Increase in intensity/duration of training, lack of recovery time, tight muscles.
What are the symptoms of tendinosis?
Swelling, ache pain when moving/touching, stiffness/weakness, decrease ROM.
What is medial tibial stress syndrome (MTSS/shin splints)?
Inflammation of the tibialis anterior/posterior muscle/tendon (myositis)
What causes medial tibial stress syndrome (MTSS/shin splints)?
Overuse of the muscle/tendon/bone, often by a sudden increase in training/training on hard surfaces. Postural alignment, poor footwear.
What are the symptoms of medial tibial stress syndrome (MTSS/shin splints)?
Shin pain/irritation/tenderness before and during but increase after rest.
What is a stress fracture?
Small cracks in a bone surface
What causes a stress fracture?
Overuse of skeletal bones often by a sudden increase/change in training/surfaces, rhythmic repetitive stress, muscle fatigue.
Increased chance in weight bearing bones eg tibia/fibula. eg cross country runners
What are the symptoms of a stress fracture?
Pain/swelling/touch sensitive, more acute during the event than after.
What is osteoarthritis?
A degenerative joint disease.
The breakdown and eventual loss of articular/hyaline cartilage at ends of bones. This cartilage lubricates, cushions, absorbs and protects the ends of the bones from wear and tear.
What causes osteoarthritis?
Abnormal/repetitive compression over time, causes microtrauma and bone thickens and forms bone spurs/projections.
Repeated sprains weaken ligaments and increase micro tears
What are the symptoms of osteoarthritis?
Joint pain, swelling and bone spurs. Limits ROM.
What are the risk factors to osteoarthritis?
Trauma Overuse Major injury in earlier life Ageing Obesity/overweight
What are the 2 types of risk factors for injury?
Extrinsic
Intrinsic
What is the definition of extrinsic risk factors?
Risk/force from outside the body eg other objects/individuals/environment
What is the definition of intrinsic risk factors?
Risk/force from within the body eg internal forces/stresses from within
What are the 4 types of extrinsic risk factors?
Inappropriate technique
Inappropriate training
Environment
Equipment/clothing
What are the 4 types of intrinsic risk factors?
Individual variables - previous injury
Individual variables - mental/psychological aspects
Training effects - physical fitness components
Training effects - motor fitness components
What are examples of Inappropriate technique as an extrinsic risk factor?
Coach Poor technique Playing time Position played Level of performance Risks unique to the sport
What are examples of inappropriate training as an extrinsic risk factor?
Too much/too soon Plyometric training before ready Inappropriate training programme (not specific) Too much overload Variance Not specific No warm up/cool down Moderation (testing)
What are examples of environment as an extrinsic risk factor?
Heat Altitude Cold Time of day Time of season Laxity of officials Crowd control
What are examples of equipment/clothing as an extrinsic risk factor?
Shin pads
Gum shield
Scrum cap
Footwear
What are examples of individual variables - previous injuries as an intrinsic risk factor?
Gender Age Physical maturation Posture/alignment Less nutrition Less joint stability
What are examples of individual variables - mental/psychological aspects as an intrinsic risk factor?
Confidence Past experience Innate intelligence Innate motivation Innate skill level
What are examples of training effects - physical fitness components as an intrinsic risk factor?
Strength How early fatigue occurs Posture/alignment Lower aerobic capacity Body composition Warm up/cool down Less flexibility
What are examples of training effects - motor fitness components as an intrinsic risk factor??
Reaction time Lower agility Slower speed Decrease coordination Less balance
