Fractures Flashcards
Define open fracture
There’s direct communication between external environment and fracture, usually through break in skin but not always (e.g. fragments of bone from a fractured pelvis penetrating the rectum)
Describe a Type I open fracture (Gastillo classification)
Low energy, wound <1cm, Clean, often bone piercing skin from inside
Describe a Type II Open fracture (Gastillo classification)
Moderate soft tissue damage, Wound <10cm, No soft tissue flap or avulsion
Describe a Type III Open fracture (Gastillo classification) and the kind of injury it results from
High energy, wound > 10cm, extensive soft tissue damage, severe fracture
Results from any gunshot, farm accident, severe crush etc.
What is the difference between Type III A, III B + III C (Gastillo classification)?
Type III A – +++ soft tissue damage but not grossly contaminated
Type III B – periosteal stripping, extensive muscle damage, heavy contamination
Type III C – associated neurovascular complication.
Define dislocation and subluxation
Dislocation – complete disruption of a joint
Subluxation – partial dislocation (not fully out of joint)
What are common sites of dislocation?
Shoulder Elbow Hip Knee Ankle Subtalar joint
What are complications of an open fracture?
Wound or tetanus infection Non-union Compartment syndrome Osteomyelitis Neurovascular injury
What are complications of dislocations?
- Tearing of the muscles, tendons and ligaments that reinforce injured joint
- Nerve or blood vessel damage in and around the joint
- Susceptibility to re-injury if you have a severe dislocation or repeated dislocations
- Development of arthritis in the affected joint as you age
Describe management of dislocations
- Reduction (moving bone back into joint)
- Immobilisation (stabilise joint once bone back in place)
- Surgery may be required if unable to put bone back into joint or if any damage to any blood vessels or nerves around joint
- Rehabilitation to restore function of affected joint
Describe the management of open fractures
- Tetanus and Abx prophylaxis
- Photograph, cover and stabilise limb
- Surgical emergency – some within 6h, all within 24hrs
What is involved in initial treatment and assessment of a fracture?
Immobilisation. Pain relief.
Assessment: clinical – fracture, circulation, neurological, open vs closed; radiological
What are conservative treatment options for fractures?
No immobilisation – strapping, brace
Immobilisation – cast, functional bracing, traction
What are operative Rx for Fractures?
External fixators – fixation from outside, pins or wires passed through skin and bone, fixed to an external frame
Internal fixation: Intramedullary rods/nailing, Screws and plates
What are the complications in external fixation?
Neurovascular injury
Pin tract infection
Loss of fracture alignment
