**Question:** Following is not a part of Ortolani test -

A. The examination of the patella or knee joint
B. The use of a stethoscope to listen for heart sounds
C. The palpation of the pubic symphysis
D. The assessment of the carotid artery for bruits

**Core Concept:** The Ortolani test is a clinical examination technique used to assess the presence of developmental dysplasia of the hip (DDH) in infants. It involves two components:

1. **Ortolani's Positive Sign:** This occurs when the femoral head is gently pushed into the acetabulum with the baby's leg extended and weight bearing on the foot. If the hip dislocates, there is a "click" heard as the head slips back into place.
2. **Ortolani's Negative Sign:** This occurs when the femoral head is gently pushed into the acetabulum with the baby's leg extended and weight bearing on the foot. If the hip dislocates, there is a "click" heard as the head slips back into place, but the click is not audible.

**Why the Correct Answer is Right:**

The Ortolani test involves the evaluation of the femoral head within the acetabulum of the hip joint. The components mentioned in the question (A, B, C, and D) are not related to the examination of the hip joint and therefore are incorrect.

**Why Each Wrong Option is Incorrect:**

A. Examining the patella or knee joint is unrelated to the hip joint examination and does not form part of the Ortolani test.
B. Using a stethoscope to listen for heart sounds is unrelated to the hip joint examination and does not form part of the Ortolani test.
C. Assessing the pubic symphysis has no relevance to the hip joint examination and does not form part of the Ortolani test.
D. Evaluating the carotid artery for bruits is unrelated to the hip joint examination and does not form part of the Ortolani test.

**Clinical Pearls:**

1. The Ortolani test is a crucial examination in the early detection and diagnosis of DDH (Dislocation of the hip joint) in infants. It is essential for pediatricians, pediatric surgeons, and other healthcare providers to be familiar with this test to identify infants with potential developmental dysplasia of the hip.
2. The Ortolani test is performed while the baby is lying supine or sitting, with the knee extended and the foot resting on the examiner's abdomen.
3. The examiner gently pushes the femoral head towards the acetabulum, listening for a "click" or "clunk" sound, which indicates a loose joint.
4. A normal hip joint will have a "click" or "clunk" sound during the examination, while an abnormal hip joint, such as in developmental dysplasia of the hip, will not produce any sound.
5. In case of a positive result, further evaluation is necessary, including radiological assessment (radiography) to confirm the diagnosis
