Study Notes
- Remodeling / Maturation starts during proliferation
- Remodeling / Maturation lasts for months to years
- During Remodeling / Maturation the repaired wound is reorganized and strengthened
- Wounded areas in general will only get to 80% of the strength of non-wounded tissue
Impairment of Wound Healing:
- Increased age can impair wound healing
- Poor nutrition can impair wound healing
- Poor hydration can impair wound healing
- Wound type can impair wound healing
- Infection can impair wound healing
- Excessive bleeding can impair wound healing
- Underlying medical conditions can impair wound healing
- Medications (anti-inflammatory) can impair wound healing
- Immunosuppression can impair wound healing
1° + 2° Wound Healing
- Primary wound healing occurs when wound edges are closely opposed
- Very little scar tissue forms during primary wound healing
- Secondary wound healing heals with more scar tissue
- Wound edges are not opposed during secondary wound healing
- Tertiary wound healing is secondary wound healing that will be closed later

Description
Wound remodeling involves tissue reorganization and strengthening, often lasting months to years. However, repaired tissues typically only regain 80% of their original strength. Factors such as age, nutrition, wound type, and medical conditions can significantly impair this healing process.
