Q

What are the risks in sport, what sports have higher risk?

A

-Risks: injury, death due to nature of sport, sudden death during exercise
-Overall risk of death is low, only 1.3% accidental deaths in UK.
Injury risk is larger with over 20million sports injuries/year in UK.
-High risk sports have higher risk, usually sports involving height, water or speed.

Q

What are microtrauma injuries and what may cause them to occur?

A

Overload injuries which will cause tissue damage, may be caused by:

  • Increased participation
  • Increased intensity and duration of training
  • Extrinsic factors: training errors, poor technique, poor conditions, incorrect equipment)
  • Intrinsic factors: anatomical and muscle imbalance

Q

Describe the cycle of injury that tissue damage from microtrauma injuries can cause?

A

The tissue damage will cause inflammation and then pain.
At this point the athlete will either rest, heal and go through rehab to correct the cause of injury.
Or they will continue activity which will lead to further damage, inflammation and pain.

A
  • Initial X-ray often normal

25
Q

Where may bursa injuries occur, and what can cause them?

A
  • Hip, knee, shoulder, feet, elbow

- Mostly from overuse but can be traumatic with bleeding

26
Q

How can bursa injury be managed?

A
  • Ice
  • Compress
  • Anti inflammatory
  • Ocassionaly aspiration
27
Q

What increases joint stability and how do they form ligaments?

A
  • Capsule of connective tissue

- Thickened at points of stress to form ligaments

28
Q

What grades can ligament injuries be classified into?

A
  • 1: fibres stretched but normal range on stressing
  • 2: more fibres involved, laxity on stressing nut definite end point
  • 3: complete tear, excessive laxity and no end point. May be pain free as nerve fibres torn.
29
Q

Generally, initially how can ligament injuries be managed?

A

-Initially minimise bleeding and swelling.

30
Q

How can grade 1 and 2 ligament injuries be managed?

A
  • Promote tissue healing
  • Prevent joint stiffness
  • Protect against further damage
  • Strenghten muscle to provide addtional joint stability
    (eg. soft tissue massage, electrotherapeutic therapies, joint mobilisation).
31
Q

How can grade 3 ligament injuries be managed?

A
  • Conservative

- Potentially surgical (direct repair or reconstruction)

32
Q

What injuries can be common at joints?

A

-Dislocation/subluxation

33
Q

Define dislocation?

A

-Trauma produces complete dissociation of articulating surfaces.

34
Q

Define subluxation?

A

-Some contact of articulating surfaces remains.

35
Q

Why is joint stability important and what does it depend on?

A
  • Important as more stable joints will need more force to dislocate
  • Dependant on anatomy
36
Q

What do joint injuries result in?

A

-Damage to joint capsule and surrounding ligaments.

37
Q

What are some complication involved in joint injuries and what can be done to exclude fractures?

A
  • Associated nerve or blood vessel damage

- X-ray to exclude fracture

38
Q

How can joint injuries be treated?

A
  • Protect to allow soft tissue to heal
  • Rebuild muscle strength
  • Early protected mobilisation
  • Muscle relaxants may be needed
  • Reduction
39
Q

How do injuries to muscle most commonly occur and what are some of the most commonly affected muscles?

A
  • Occurs when demands exceed muscle capacity
  • Common if 2 joints cross
  • Common during sudden acceleration and decceleration
  • Commonly affected; hamstring, quadriceps, gastrocnemius
40
Q

What 3 grades can muscle injuries be classified into?

A
  • 1: few fibres, localised pain and no loss of strength
  • 2: significant no. of fibres, selling, pain on contraction, reduced strength and limitation of movement
  • 3: complete tear, most common at musculotendinous junctions
41
Q

How can muscle injuries be managed?

A
  • 1st aid to minimise bleeding and swelling and inflammation
  • Electrotherapy eg. ultrasound
  • Soft tissue therapy
  • Stretching

42
Q

What are some predisposing factors that may lead to muscle injury?

A
  • Inadequate warmup

47
Q

What may cause contusions?

A

-Results from direct blow from opponent or contact with equipment. This will result in local damage and bleeding.

48

51
Q

How should myositis ossificans be diagnosed and what is recovery like?

A
  • Suspect if slow resolution and diagnose on x-ray after 10-14 days.
  • Most resolve spontaneously and recovery is slow
52
Q

What do normal tendons consist of?

A

-Tight paralell bundles of collagen fibres

53
Q

Where do tendon injuries tend to occur?

A

-Usually at point of least blood supply eg. achilles tendon at musculotendinous joint.

54
Q

What types of tendon ruptures may occur and how do ruptures usually occur?

A
  • Complete
  • Partial
  • Usually occur without warning (more common in older athlete).
55
Q

What are the most commonly injured tendons?

A

Achilles and supraspinatus

56
Q

Anatomically, where does the achilles tendon run?

A

-From calf muscle (gastrocnemius) to insert into posterior aspect of heel (calcaneum).

57
Q

What type os injury is achilles tendonopathy?

A
  • Chronic repetitive overload injury

- Common with sudden increase in activity or change in technique.

58
Q

What ae some of the symptoms of achilles tendnopathy?

A
  • Pain esp. uphill
  • local swelling
  • local tenderness
  • crepitus on ankle movement
59
Q

How can achilles tendonopathy be prevented?

A
  • Proper warm up and stretching
  • Good shoes with no heel tabs
  • Heel wedge
60
Q

How may achilles tendonopathy be treated?

A
  • Heel wedge
  • NSAIDs
  • Active rest
  • No steroid injections
  • Alter training (no hills, decrease pace)
  • Immobilisation
  • Surgery for chronic tendonitis or rupture
61
Q

What are some complications that may arise in an achilles tendonopathy patient?

A
  • Achilles bursitis
  • Rupture
