The Morgan line refers to osteophyte formation on which part of the femur?

The Morgan line refers to osteophyte formation on which part of the femur?

• A. Neck of the femur
• B. Acetabulum
• C. Shaft of femur
• D. Lesser trochanter

Answer: (A)

Osteophyte formation is a bone response to joint degeneration, showing up at the margins of the articular surfaces. In the hip, this reactive bone growth commonly appears along the femoral neck, producing a thin radiopaque line known as the Morgan line. That location at the femoral neck is what this sign highlights, because the neck is a joint-margin area where osteophytes develop in response to hip joint disease. The acetabulum and shaft are not the typical margins involved for this radiographic sign, and the lesser trochanter is not a primary site for osteophyte formation in this context.
