Although its de- terminations are, from the nature of the case, only approximate, the goniometer is an instrument of pre- cision, and easily makes itself useful in practice. Writers on this subject have usually viewed de- formity as the result of immobilization of the hip joint. The figures and models referred to in this article have been constructed with that view. As FIGURE 10. a matter of fact, however, few cases present ab- solutely immovable joints at any stage. There is almost always considerable motion. In the acute stage the joint, which at the first glance appears to be motionless, is found to yield through an arc of many degrees in response to gentle force rightly ap- plied. Later in the course of the disease many cases show wide and free passive motion in different direc- tions, and the point at which motion is arrested often varies from day to day. And even in after life the
