Coxa vara at the hip joint occurs when the angle is defined as?

1. More than 150 degrees

2. Less than 125 degrees

3. More than 35 degrees

4. Less than 35 degrees

The correct answer is: Less than 125 degrees

Coxa vara is a condition at the hip joint characterized by an abnormal decrease in the angle between the neck and shaft of the femur. This angle, known as the femoral neck-shaft angle, is normally around 125 degrees in adults. When this angle is less than 125 degrees, it indicates coxa vara. The reduced angle leads to changes in hip biomechanics and can influence the alignment and function of the lower extremity. In this context, recognizing the normal range of the femoral neck-shaft angle helps in understanding various hip conditions. A femoral neck-shaft angle that is less than 125 degrees signifies a potential pathological state that could lead to functional impairments or pain. Other options referring to angles greater than 125 degrees or specific lower thresholds do not pertain to the diagnosis of coxa vara. Understanding these angles is crucial for physical therapists in both evaluation and intervention strategies for patients experiencing hip-related issues.
