Limbs Flashcards
Name the 4 components of the mangled extremity severity score
- Skeletal/soft tissue injury 1-4
- limb ischaemia 1-3
- shock 0-2
- age 0-2
Which score of the mangled extremity severity score predicts an eventual need for amputation?
> 7
Name 3 early complications hip dislocation
- Sciatic nerve injury 10-20%
- vascular injury (sup gluteal artery )
- associated shaft fracture
Name 3 complications knee dislocation
- Vascular injuries 40-50%
- nerve injury common peroneal 25%
- fractures 60%
Complication of untreated supra condylar fracture?
Gun stock deformity
Name 10 indications for ORIF
- Intra-articular fractures: salter Harris 3 and 4
- fail to achieve reduction
- failure to maintain reduction
- neck femur fracture
- lateral condyle humerus,
- supra condylar fracture,
- avulsion fracture
- poly trauma
- multiple fractures
- Bilateral femur fractures
- floating knee
- humerus and forearm fracture
- Compound fractures
- neurovascular compromise or injury
- pathological fractures
Treatment of shoulder dislocation?
Urgent closed reduction
Management of most proximal humerus fractures?
Analgesia and sling immobilisation
When should a proximal humerus fracture be referred to Ortho for surgery? (4)
- Neurovascular injury
- open
- associated dislocation
- markedly displaced
Which neurovascular structures should be examined in humerus shaft fractures?
Radial nerve (cross distal to spiral groove of humerus ) Brachial artery (medial to humerus proximally, then move ant to lie between epicondyles of humerus)
Treatment of forearm fractures?
ORIF because all are unstable!
