The Ortolani test is part of the routine newborn physical exam, and knowing when and why it is performed narrows down what it is checking for.
- Congenital hip dislocation: Newborns are screened for developmental problems in the hip joint because early detection allows simple treatments, like a harness, to work well. The Ortolani manoeuvre reproduces the relocation of a dislocated hip, so a positive result flags this specific condition.
- Club foot: This condition is obvious on visual inspection of the foot at birth and does not need a hip abduction test to identify.
- Fractures: Newborns rarely have unexplained fractures, and when they do occur, they are found through swelling and pain on limb movement, not this hip test.
- Bone injuries: These are picked up through visible trauma or abnormal movement, and would not specifically require the Ortolani manoeuvre to detect.
Because this test is designed around detecting a hip joint slipping in and out of its socket, it exists specifically to screen for congenital hip dislocation.
Therefore, the correct answer is Congenital hip dislocation.
