Question

Quizplus · Accepted Answer

Posterior dislocation of hip is associated with shortening of limb and hip flexion, adduction, and internal rotation deformity.
Shortening of limb along with the hip flexion, adduction, and internal rotation deformity are the keywords to get the correct answer in this question.
In a posterior fracture dislocation of hip joint, the knee will be flexed along with slight abduction of limb.
In anterior dislocation, the expected deformity is thigh abduction, flexion, and external rotation.
In central dislocation of hip, there will be no limb shortening. The mechanism of injury is usually a direct blow over the trochanters.
