Which condition is identified by an increased angle of inclination in the hip joint?

The condition characterized by an increased angle of inclination in the hip joint is indeed coxa valga. This term refers to a situation where the angle between the neck and shaft of the femur is greater than the normal range, typically more than 130 degrees. This increased angle can result in structural changes and affects the biomechanics of the hip joint, potentially leading to altered gait and increased stress on the hip and surrounding structures.

In contrast, coxa vara is associated with a decreased angle of inclination, which can lead to different complications in hip function. Osteoarthritis primarily involves the degradation of joint cartilage and does not inherently relate to the angle of inclination. A fracture of the femur can occur in various scenarios but does not specifically denote an increased angle of inclination either. Thus, coxa valga is the correct identification based on the characteristic of an increased angle at the hip joint.
