What condition is associated with a decreased angle of inclination in the hip?

Coxa vara is characterized by a decreased angle of inclination at the hip joint, which refers to the angle formed between the shaft of the femur and the neck of the femur. In coxa vara, this angle is typically less than 120 degrees. This reduced angle can lead to various biomechanical changes and functional impairments in lower extremity alignment and stability. It often results in a shorter effective length of the femur, which may affect gait and increase the risk of certain loading conditions that can lead to further complications in the hip joint.

In contrast, coxa valga is characterized by an increased angle of inclination, hip dysplasia involves an abnormal formation of the hip joint, and joint hypermobility relates to increased range of motion at various joints rather than an angle of inclination specifically in the hip. Each of these conditions presents distinct anatomical and functional characteristics that differentiate them from coxa vara.
