joint dislocations

what deformities are seen in shoulder dislocation

anterior - squared off

locked in internal rotation - posterior

diagnosis of dislocation

X-ray

clinical examination

dislocation

complete joint disruption

subluxation

partial dislocation

not fully out of joint

diagnosis of dislocation

clinical and radiological diagnosis

associated injuries with dislocation

soft tissue, multisystem, neurovascular damage, recurrent instability

deformity of elbow common dislocation

posterior direction

olecranon prominent post

hip deformity common dislocation

posterior direction

leg short, flexed, internal rotation adduction

knee deformity commonest dislocation

anteroposterior direction

loss of normal contour, extended

ankle deformity commonest dislocation

lateral

externally rotated, prominent medial malleolus

subtalar joint deformity commonest dislocation

lateral displaced os calcis

ankle dislocation if dislocated for a length of time as skin will necrose → large defect over medial malleolus

what might happen?

secondary infection

very stiff → secondary osteoarthritis

when is neurovascular assessment performed and why

pre and post reduction to ensure no nerves or vessels were compromised during the injury of fix
