The development of the normal infantile hip as expressed by radiological measurements.
Acetabular and centre edge angles were measured on normal radiographs of 164 children (328 hips) aged from three months to five years. Using regression and correlation analysis, mathematical formulae were derived which allow the calculation of the normal acetabular and centre edge angles for a given age. The relationship between age, acetabular angle and centre edge angle was studied.
