What is a correct way to identify the starting point for a proximal femur scan?

• A. Align the laser with the femoral shaft
• B. Palpate the greater trochanter, center the laser at that level, and adjust as directed
• C. Identify the midpoint between the knee and hip
• D. Measure the distance from the iliac crest

Answer: (B)

To accurately identify the starting point for a proximal femur scan, it is essential to palpate the greater trochanter. This anatomical landmark serves as a reliable reference point for locating the correct scan position. Once the greater trochanter is palpated, centering the laser at that level ensures that the scan will capture the desired region of interest, which is critical for obtaining precise bone density measurements. The proximal femur is specifically the area where osteoporosis-related fractures frequently occur, making accurate scanning vital. Adjustments might be needed as per specific protocols or instructions to ensure optimal positioning. Proper alignment and centering at the greater trochanter contribute to the consistency and reliability of the results obtained from the bone densitometry scan.
