How to Develope a Novel 3D Printed Integral Customized Anatomical Acetabular Prosthesis in Hip Arthroplasty for Crowe Type II and III Developmental Dysplasia of the Hip?

Background The acetabular pathomorphology in patients with Crowe type II and III developmental dysplasia of the hip often has been criticized by persistent changes, which pose a challenge to the anatomical reconstruction of acetabular arthroplasty. Patients with end-stage hip osteoarthritis in connection with Crowe type II/III THA were included in Methods 15 patients with end-stage hip osteoarthritis from January 2015 to November 2021. Prosthetically, there was no statistically significant difference between the application group and model group on cup size, the horizontal and vertical distance of hip center, and the THA's unique 3D printed integral anatomical acetabular prosthesis with high precision and accuracy.

Combined femoral and acetabular version is sex-related and differs between patients with hip dysplasia and acetabular retroversion.

Patients and methods A retrospective IRB-approved observational research was conducted with 78 symptomatic DDH patients and 65 patients with femoroacetabular immunization as a result of AR. DDH patients were significantly higher than average DDH patients compared to AR, with an increase in FV and CV. Female DDH patients and AR were significantly higher than male DDH patients and AR compared to male DDH patients and AR. Frequency of elevated FV was 47 percent, with dramatic risen FV of 29 percent in DDH patients, at 23 percent. In patients AR compared to DDH patients, the proportion of femoral retroversion was much higher than in DDH patients. Patients with AV>25&u00b0 mixed with FV > 25 percent had a DDH status of > 25 %, with FV > 25. 00. Patients with DDH and AR have striking sex-related differences in FV and CV, resulting in dramatic sex-related variations in FV and CV. For patients with DDH, a high frequency of increased FV> 35b0 is significant, but 17% showed decreased FV, which may have influenced management.
