The roentgen-and-anatomic criteria defining the hip instability in children

The technique is presented for determination of the main roentgenological parameters which characterize the hip instability. The results of these measurements are given in 62 patients with the hip subluxation and in 101 patients with the hip dislocation. The roengenologic criteria described are of chief importance for determination of indications to reconstructive- and-restorative intervention performance and extent and also for selecting the optimal variant of correction of the hip components.
