Fig. 4From: Prediction of time to prosthesis implantation as a function of joint anatomy in patients with developmental dysplasia of the hipScatter plots illustrating the statistical relationship of age at pTHA, LCE angle (a) and AI (b). R is 0.37 and − 0.29, respectively. These scatter plots of the LCE and acetabular indices against age illustrate the unambiguous relationship of age in primary THA with LCE angle and AI. Thus, the mean possible age of the necessary prosthesis implantation as a function of LCE angle and AI can be read from these diagramsBack to article page
