A patient with hip dislocation with limitation of Abduction at hip and flexion and internal rotation deformity at hip and shortening. Diagnosis is:
Central dislocation
Anterior dislocation
Posterior dislocation
Fracture dislocation
(c) Posterior dislocationExplanationSince the question mentions limitation of abduction, hence there is adduction deformity along with flexion and internal rotation deformity. Thus this is a case of Posterior dislocation of hip.Position of hipPattern of InjuryFlexion, adduction, internal rotationPure posterior dislocationLess flexion, less adduction (neutral or slight abduction), internal rotationPosterior fracture dislocation > central dislocationHyper abduction + Flexion + External rotationAnterior dislocationSome students remember an alternate format of the question 6b
