What angle of measurement indicates coxa valga?

• A. Less than 90 degrees
• B. Between 90 and 125 degrees
• C. Greater than 125 degrees
• D. Exactly 125 degrees

Answer: (C)

Coxa valga is characterized by an increased angle of femoral neck-troat, typically defined as greater than 125 degrees. This condition results from a structural alteration of the hip joint that leads to an outward positioning of the femur in relation to the hip, which can contribute to various functional issues such as gait abnormalities and increased risk of hip injury.

In contrast, less than 90 degrees indicates coxa vara, which is a condition where the angle is decreased, leading to an inward position of the femur. An angle between 90 and 125 degrees is considered normal. Lastly, an angle that measures exactly 125 degrees falls within the normal range and does not indicate coxa valga. Thus, the precise measurement for identifying coxa valga is specifically defined as greater than 125 degrees.
