Coxa vara is an anatomic term introduced by Müller,1 who applied it to those cases in which there was adduction of the distal part of the lower limb toward the sagittal plane of the body, caused by a lowering of the femoral head. Müller1 considered the condition analogous to pes varus. Later, Kocher2 wished to reserve the term coxa vara for the adolescent type only, a type associated with external rotation and whose etiology is uncertain, and for that of known etiology he introduced the term coxa adducta. This distinction, however, was not generally accepted, and the term coxa vara is now used in a wide sense to include all cases in which there is a diminution in the angle formed by the neck and the shaft of the femur, whether or not it is associated with external rotation.
