fractures Flashcards
compartment syndrome cause
develops due to build up of pressure within the fascial compartments
compartment syndrome presentation
- swelling
- out of proportion pain
- pain on passive stretch
- decreased temperature
- loss of pulses
- intra-compartment pressure > 30 mmHg
compartment syndrome management
fasciotomy
complication of compartment syndrome
Volkmann’s ischaemic contracture
Volkmann’s ischaemic contracture cause
due to failure to treat compartment syndrome resulting in muscle necrosis and fibrosis
fractures especially at risk of avascular necrosis
- scaphoid
- proximal talus
- head of humerus
- femoral condyles
- intra-capsular femoral head
what is a surgical neck of humerus fracture
fracture of ulna and dislocation of radial head at elbow joint
surgical neck of humerus fractures are most common in
elderly patients with osteoporosis
surgical neck of humerus fracture associations
- avascular necrosis
- axillary nerve damage (presents with loss of sensation over badge patch area i.e. C5)
surgical neck of humerus fracture management
- most commonly managed conservatively
- open reduction and internal fixation of ulna
mechanism of humeral shaft fracture
fall on outstretched hand
humeral shaft fracture association
radial nerve damage (presents with wrist drop and loss of sensation in dorsal first web sapce)
humeral shaft fracture management
conservative (traction brace)
mechanism of olecranon fracture
fall onto point of elbow, with triceps contracted
olecranon fractures result in
avulsion of olecranon process
radial head fractures result in
loss of pronation and supination
radial head fracture associations
- elbow dislocation
- fat pad sign on x-ray
radial head fracture management
conservative
what is a Galeazzi fracture
radial head fracture with ulnar dislocation
what is a Monteggia fracture
ulnar fracture with radial dislocation (more common)
mechanism of a Colles fracture
fall on outstretched hand with wrist extension
what is a Colles fracture
extra-articular fracture of the distal radius with dorsal displacement (broken end of bone points back)
Colles fracture presentation
dorsal displacement and angulation of the wrist (dinner fork deformity)
Colles fracture associations
- median nerve compression
- extensor pollicus longus rupture
- Sudecks dystrophy
mechanism of Smith’s fracture
fall on outstretched hand with wrist flexion
what is a Smith’s fracture
extra-articular fracture of the proximal radius with volar displacement (broken end of bone points forwards)
Smith’s fracture presentation
volar displacement and angulation of the wrist
Smith’s fracture management
open reduction and internal fixation (unstable fracture)
what is a Barton’s fracture
intra-articular fracture of the wrist
