31
When do we seek medical attention?
- unable to control bleeding
- wound is dirty and unable to be cleaned
- deep wound or puncture
- object is still impaled
- changes in sensation
- wound is from human/animal bite
- wound is from rusty object
32
Cartilage and meniscus healing
- limited capacity to heal
- little or no direct blood supply
33
Ligament healing
- during repair phase, collagen or connective tissue fibres lay down randomly
- gradually scar is formed
- over following months collagen fibres align in response to joint stress/strain
34
Skeletal muscle healing
- regeneration of new myofibers is minimal
- healing and repair follows the same process of random collagen alignment and develops tensile strength in response to stress/strain
35
Healing of nerves
- regeneration can take place very slowly (3-4mm/day)
- peripheral nerves regenerate better than central nervous system
36
Phases of wound healing
1. Hemostasis
2. Inflammation
3. Repair and regeneration
4. Remodelling
37
Hemostasis
Process leading to cessation of bleeding
38
What is inflammation?
Essential vascular and cellular response for proper tissue healing
39
Repair and regeneration- what is formed?
Formulation of granulation tissues
40
Timeline of stages of wound healing
1. Inflammation: 4-6 days
2. Proliferation: 4-24 days
3. Remodelling: 21 days -2 years
41
Tissue response to injury (acute)
Acute musculoskeletal injuries fall into 3 phases:
1.Inflammation
2. Repair and regeneration
3. Remodelling
42
Phase 1: Inflammatory response (acute)
- vasodilation of blood vessels
- white blood cells (neutrophils and macrophages) fight infection, break down and clean up damaged tissue
43
Signs and symptoms of inflammation
- redness
- swelling
- heat
- pain
- loss of function
44
Phase 2: Repair and regeneration (acute)
- collagen laid down in disorganized mix
- revascularization bring oxygen and nutrients
- edges of wounds draw closer
45
Phase 3: Remodelling (acute)
- collagen reorganizes along lines of stress (Wolff's law)
- tissues increase in tensile strength
46
Tissue healing phases (table)
1. Inflammatory response phase
2. Fibroblastic repair phase
3. Maturation-remodelling phase
47
Inflammatory response phase (table)

48
Fibroblastic repair phase (table)

50
Bone healing 5 stages
