Flashcards in Chronic Injury Deck (20):
1

How do regeneration & fibrosis affect permanent repair?

The fibrosed area matures & contracts, the epitherlium thickens, resulting in a fully regenerated epithelium with an underlying area of scar tissue

2

When does a permanent scar occur?

When damage is deeper than 33% skin thickness or takes more than 3 weeks to heal

3

What is scar tissue comprised of?

Disorganised collagen matrix produced by myofibroblasts

4

What are the characteristics of a normal scar?

- Confined to edges of original wound
- Gradual fading and atrophy
- No treatment
- Best in elderly

5

What are the characteristics of a hypertrophic scar?

- Confined to edges of original wound
- Regresses after initial peak (often over several years)
- Treatment: Silicone patches or gels
- Worst in the young

6

What are the characteristics of a keloid scar?

- Extends beyond edges of wound
- Progressive
- Treatment: Intralesional steroids
- More common in darker skin
- Failure of apoptosis

7

What are the types of treatment for skin wound healing?

Silica gel patches, compression, hydrotherapy, steroid injections, laser, liquid nitrogen

8

How are muscle tears classified?

Grade 1, 2, 3 tears - grade 3 is complete tear with complete loss of function

9

What is the treatment for muscle tears?

Rest (less than 1 week)

10

What occurs during the late phase of muscle repair?

- Atrophy from injury & disuse
- Reduced length
- Reduced flexibility/elasticity
- Reduced cardio training
- Reduced whole body stability, core strength & agility

11

What are the symptoms of late stages of repair?

- Shortened tissue length
- Tenderness, sensitivity or pain when performing the movement
- Stiff to get moving, sore after exercise
- Weak, poorly controlled, fatigues early

12

How can lung tissue be damaged?

By infections, chronic inflammation & chronic lung diseases

13

What are the characteristics of pulmonary fibrosis (lung scarring)

- Shortness of breath
- Dry cough
- Fatigue, weakness
- Loss of appetite, weight loss

14

What are the treatments for damaged lung tissue?

- Breathing exercises
- Physical training for inspiratory muscles & peripheral muscles

15

What are the rough recovery times for:
- Muscle strain
- Ligament
- Bone
- Chondral cartilage
- Vessel
- Tendon
- Strength
- Control/skill

- Muscle strain: 3 days-6 weeks
- Ligament: 4-8 weeks
- Bone: 6-8 weeks
- Chondral cartilage: 6 weeks-never
- Vessel: Up to 3 weeks
- Tendon: 3-18 months
- Strength: 6-8 weeks
- Control/skill: 2-4 weeks

16

What tendons commonly experience chronic overuse injuries?

- Supraspinatus
- Medial/lateral elbow
- Achilles
- Patella
- ITB
- Gluteus medius

17

What bones commonly experience chronic overuse injuries?

- Stress fractures tibia, feet
- Cartilage/menisci
- Knees
- Hands
- Shoulders
- Wrists

18

What are the interventions for chronic overuse injuries?

- Address the balance
- Unload
- Increase flexibility & resilience
- Address biomechanical issues
- Increase training more slowly
- Rest days
- Cross training

19

What interventions facilitate slow tissue repair & restore function?

- Warm-up
- Graduated return to activity
- Stretching
- Strengthening
- Core stability/cardio

20

Why is a warm-up important?

Increases elasticity, relaxes muscles
