Final answer:
A patient with a posterior dislocation of the hip would have a leg that is unable to move backwards or extend at the hip joint.
Step-by-step explanation:
A patient with a posterior dislocation of the hip would have a leg that is unable to move backwards or extend at the hip joint.
In a normal hip joint, the hamstring muscles in the posterior compartment of the thigh are responsible for moving the leg up and back toward the buttocks, as when kneeling. However, in a posterior dislocation, the femur bone at the hip joint is displaced posteriorly or towards the back, causing a disruption in the normal range of motion.
As a result, the patient would experience limited movement in the leg and would be unable to perform actions such as bending the leg backward or kneeling.
