Fractures Flashcards
Open fracture
Open wound
Due to a spike of fractured bone puncturing the skin
Closed fracture
Skin is in tact
Displacement
Direction of translation of the DISTAL fragment
- can be described as medially/laterally/anteriorly/posteriorly displaced
Displacement terms in the hand and forearm
Direction of translation of the DISTAL fragment
- can be described as ulnar/radial/volar/dorsal displacement
Angulation
Direction which the distal fragment points towards and the degree of this deformity
- can be described as medially/laterally/anteriorly/posterior angulation
Angulation terms in the hand and forearm
can be described as ulnar/radial/volar/dorsal displacement
Angulation terms in the lower limb
Varus/valgus/anteriorly/posteriorly
Intra-articular fracture
Fracture extends into the joint
Extra-articular fracture
Fracture does not extend into the joint
Name the 5 fracture patterns
Transverse Oblique Spiral Comminuted Segmental
Transverse fracture
clean fracture straight across horizontally
Oblique fracture
diagonal fracture (at an angle)
Spiral fracture
From twisting injuries
In an S shape
Comminuted fracture
Fracture with 3 or more fragments
Segmental fracture
Bone has fractured in 2 separate places
Very unstable
X ray
Usually need an AP and lateral view
CT
Can determine the degree of articular damage
MRI
Detects occult fractures (clinical suspicion of fracture but normal X-ray)
Primary bone healing
Minimal fracture gap and the bone simply fills the gap with new bone from osteoblasts
Secondary bone healing
Gap at the fracture site which needs to be filled temporarily (by cartilage) in order for new bone to be laid down
Initial fracture management
Analgesia (IV morphine)
Immediate management if there is obvious displacement / dislocation
IV morphine
Immediate reduction
Management of stable fractures
Non operative
- splint
- immobilisation (cast)
- bracing
- rehabilitation
Management of unstable fractures
Reduction under anaesthetic
Surgical stabilisation
- internal fixation
- external fixation
