Coxa vara Health Dictionary

A deformity of the hip in which the angle between the neck and head of the femur (thigh-bone) and the shaft of the femur is reduced, resulting in shortening of the leg, pain and stiffness in the hip, and a limp. The most common cause is a fracture to the neck of the femur or, during adolescence, injury to the developing part of the head of the bone. Coxa vara can also occur if the bone tissue in the neck of the femur is soft, a condition that may be congenital or the result of a bone disorder such as rickets or Paget’s disease. Treatment may include surgery (see osteotomy).

A condition in which the neck of the thighbone is bent so that the lower limbs are turned outwards and lameness results.
