Influencing factors on healing Flashcards
How does infection influence healing?
Colonisation of bacteria = necrosis & oedema = slower healing
How does loss of bone apposition influence healing?
Separation or interposition will affect healing
How does vascular injury influence healing?
Disruption of blood supply
How do intra-articular fractures influence healing?
- Synovial fluid collagenases, which retard bone growth
- Joint movement cause fragments to move = slower healing
How does degree of immobilisation of fracture influence healing?
Immobilisations help with healing
How does degree of trauma influence healing?
More disruption to soft tissues = slower to heal
How do systemic diseases influence healing?
Diabetes & osteoporosis = slower healing due to decreased number of proliferating cells
How does diet influence healing?
Bone & soft tissues healing requires large amounts of calories, minerals and proteins
How does smoking influence healing?
At high risk of complications (e.g.: delayed or non-union, slower healing times of fracture and wound)
How does age influence healing?
Younger patients have greater ability to remodel
