Reconstructing Pelvic Discontinuity and Severe Acetabular Bone Loss in Revision Hip Arthroplasty with a Massive Allograft and Cage

TOTAL HIP JOINT REPLACEMENT USING A CUSTOM TRIFLANGE ACETABULAR COMPONENT (LITERATURE REVIEW)

OBJECTIVE

The aim: The purpose of the article is to analyze the ways of solving the problem of revision hip joint replacement. The article discusses the methods of treatment using a custom triflange acetabular component.

PATIENTS AND METHODS

Materials and methods: The analysis of 37 literary sources includes a discussion of the features of the use of individual triflange acetabular components and errors in revision hip arthroplasty, which are associated with various factors.

CONCLUSION

Conclusions: A review of studies devoted to the use of custom triflange acetabular components confirms the effectiveness in the early postoperative period in the treatment of critical acetabular defects and pelvic ring discontinuity. The CTAC use is particularly relevant in case of the pelvic ring disintegration, as it provides for the appropriate endoprosthesis adaptation with the healthy bone, as well as for the bone defects plastics and recovery of the hip joint biome¬chanics. So, the use of individual constructions is indicated for the patients with significant bone mass loss, where augment adaptation and adjustment is impossible. This method is used more often when there is no other alternative. Research results showed a trend that special three-flange components of the acetabulum have better long-term results compared to traditional standard components for large bone defects. Improving production and increasing the number of CTACs should reduce their cost. In summary, the custom triflange acetabulum components provide a personalized secure fit that can reduce the risk of complications and improve patient outcomes. In summary, the triple-flange acetabulum components provide a personalized secure fit that can reduce the risk of complications and improve patient outcomes.
