Coxa Valga is often associated with which angle change in the femur?

Coxa valga refers to a condition where the angle between the neck and shaft of the femur is increased beyond the normal range. This angle is known as the femoral neck-shaft angle, and its normal range is typically between 125 and 135 degrees. When this angle becomes greater than 135 degrees, it is classified as coxa valga.

An increased angle to the axis means that the femur is positioned in a way that creates a larger angle between the neck of the femur and the shaft, resulting in a straighter alignment of the shaft relative to the pelvis. This can lead to several biomechanical changes in the hip and lower limb, affecting gait and load distribution.

Understanding coxa valga is crucial in orthopedic practice, as it can influence the risk of certain conditions, such as hip osteoarthritis or issues with balance and stability during movement. Thus, recognizing that an increased angle to the axis of the femur is characteristic of coxa valga helps in the assessment and management of patients with this condition.
