How is the Allis/Galeazzi/Skyline Sign test performed?

• A. Patient standing with one leg lifted
• B. Patient supine with knees flexed and heels even
• C. Patient lying prone with legs extended
• D. Patient seated with feet flat

Answer: (B)

The Allis/Galeazzi/Skyline Sign test is performed with the patient in a supine position, which allows for an effective assessment of the alignment and level of the knees when they are flexed. During this test, the patient's knees are flexed, and their feet are placed flat on the table. The clinician assesses the height of the knees relative to each other to identify any discrepancies, which can indicate conditions such as hip dislocation or developmental dysplasia.

This position is crucial because it allows for a clear visual assessment of any asymmetry between the femurs. When the knees are flexed and positioned this way, any abnormal height in one knee compared to the other can highlight underlying joint or developmental issues. Other positions mentioned, such as standing or lying prone, would not facilitate the same type of assessment, making them unsuitable for this specific evaluation.
