Fractures profoma Flashcards
Epidemiology of fractures?
More common in young men- as more likely to be exposed to trauma
More common in older women- due to menopause & lack of protective effect of oestrogen
Presentation of fractures?
Localised pain- worsened by movement
deformity
Crepitus
abnormal movement of limb
Examination: leg externally rotated & shortened
patient has clear history- Use AMPLE
- A- allergies
- M- medications
- P- past medical history
- L- last meal
- E- events- what happened
Investigations for fractures?
X-ray from 2 planes at 90 degrees from each other
- Include whole bone- joint above & below
CT for complex fractures
MRI for soft tissue injuries
Management for fractures?
- Analgesia e.g. diamorphine
- reduce fracture- control bleeding, cover wounds
- reassess neuromuscular status- pulse, sensation, movement
- Antibiotic & tentas prophylaxis
- Surgery if needed
- Plaster or splint for 4-6 weeks- stabalisation- screws or plates
Complications of fractures?
Nerve palsy
Haemorrhage
Hypovalaemic shock- blood loss
Infection
non-union- failure of a fractured bone to heal & mend after an extended period of time
malunion- fracture that has healed in a deformed position, or w/ shortening or rotation of the limb.
Avascular necrosis
deformity
OA
fat embolism
Prognosis of fractures?
Depends on bone broken, location of fracture, presence of complications or underlying medical condition
Can take up to 18 months for fracture to heal
If patient complains about progressive pain on walking years after fracture but w/ no systemic symptoms= acetabular wear
Why do fractures in some patients heal slowly?
- Bone type: cancellous bone heals faster than cortical
- type: transverse takes longer than spiral
- Blood supply: poor circulation delays healing
- Diet: deficiency in Ca and Vit D will delay healing
- Age: children heal twice as fast as adults, once growth plates fuse healing rate is constant at all ages
- Smoking: adversely affects rate and quality of union
- Causes of non union: poor fixation (disrupts callus formation), insertion of soft tissue between # fragments, severe soft tissue damage, infection, abnormal bone
