My remarks are to be confined to those cases of coxa vara of the adolescents in which a causative or contributary relation exists between trauma and deformity.
In a general way it is now conceded that separation of the upper epiphysis of the femur is likely to occur from trauma, either as partial or as complete separation or decollement of the epiphysis. For practical purposes, however, much of the information drawn from literature is too casuistic and dogmatic. On the other hand, considerable work has been done to establish definite facts in regard to practical questions of etiology and diagnosis. For instance, what is not only possible but likely to result from certain trauma to the hip in certain ages? What amount of violence is necessary to produce gross changes in the adolescent hip? What is the influence of chronic or repeated traumatism? And what is known of the relation
