Describe the three stages of tissues healing

Question 1

1st Stage of tissue healing (including time lines)

Answer 1

INFLAMMATION PHASE ( Days 1-0):

• Inflammatory response
• Remove foreign debris + reduce chance of infection to max tissue healing.
• Clinical Implications:
• Cardinal signs + symptoms
• Min loss of function by address pain + swelling.
• Tx:
• RICE

Question 2

2nd Stage of tissue healing

Answer 2

REPAIR PHASE (Days 3-20):

• Formation of granulation tissue
• Regeneration of epithelial cells
• Fibres are thin & weak
• Clinical Implications:
• Early scar formations, easily damaged + easy to bleed.
• Tx:
• Balance early ROM with minimizing trauma to fragile area.

Question 3

3rd Stage of tissue healing

Answer 3

REMODELING PHASE (Days 9+):

• Restore tissue function as close to normal as possible.
• Production of scar tissue + strength of fibres
• Depending on type of tissue: can last 3 months to 2 years.
• The tensile strength of new collagen is related to the forces applied to the tissue during this phase.
• Clinical Implications:
• Need to know when it is appropriate to mobilize healing tissue.

-Tx: Balance mechanical force application with min further damage.
