Flashcards in Tissue Healing Rates Deck (31):
What are the timeframes of acute, subacute and chronic injuries?
Acute: 0-6 weeks
Subacute: 5-12 weeks
Chronic: 6+ weeks
What type of health facilities would subacute patients be referred to?
Rehab centre, palliative care, convalescence
When does a scar occur?
When there is more than 33% damage and when it takes longer than 3 weeks to heal
What is the normal healing time for skin?
2-3 weeks, stitches out day 7-10, scar management day 10-18 months
What are three types of scars?
Normal, hypertrophic, keloid
How are muscle tears classified?
Grade 1: Sprain/strain (few fibres)
Grade 2: Disruption (bleeding, dysfunction)
Grade 3: Complete tear, requires surgery
What is the acute treatment for Grade 1 & 2 tears?
RICE, gentle mobilisation within first week
What does rehab for muscle tears involve?
ROM, stretching, strengthening, core work, coordination work
How does lung tissue damage occur?
Infections, chronic inflammation, smoking (emphysema, chronic bronchitis, pulmonary fibrosis)
What is the recovery time for ligaments?
4-8 weeks, depending on site and grade
What is the recovery time for bone?
6-8 weeks for upper limb, 12 weeks for lower limb
What is the recovery time for chrondral cartilage?
6 weeks to never, very unreliable healer
What is the recovery time for vessels?
What is the recovery time for tendons?
What is the recovery time for strength and control/skill?
Strength: 6-8 weeks
Control/skill: 2-4 weeks
What are ligaments and tendons made up of?
Collagen bundles with few blood vessels
What is the paratendon?
Surrounds the whole tendon, contains most of the blood vessels and nerves
What are the 4 stages of bone healing?
1) Hematoma formation
2) Soft callus formation
3) Hard callus formation
4) Bone remodelling
What are the variables that affect bone healing time?
Faster healing time: Upper limb, child, non-smoker, pre-menopause
Slower healing time: Lower limb, adult, smoker, elderly
What are the two classification systems for chondral lesions?
Outerbridge & International Cartilage Repair Society (ICRS)
What are the 6 ICRS grades for chondral lesions?
I: Superficial fissure
What tissues have lymphatic supply?
Muscle, blood vessel and brain
What tissues have blood and nerve supply?
Muscle, bone, blood vessel, brain
What tissues do not have blood, nerve or lymphatic supply?
Ligaments, tendons, chondral cartilage
What are the characteristics of a traumatic brain injury?
- Documented loss of consciousness
- Skull fracture, post-traumatic seizure, or abnormal brain scan
What are the effects of traumatic brain injury?
- Stretching/sheering of axons
- Bleeding, causing high pressure & swelling
What are the two stages of traumatic brain injury?
Transient (concussion) and long term damage
What measurement tool is used for long term traumatic brain injury?
Glasgow Coma Scale
What are the two types of stroke?
Ischaemic: Blood clot (87% of cases)
Haemorrhagic: Artery bursts
What are the recovery times for transient and long term brain injury?
Long term: Weeks-years
