Objectives: The aim of this study was to compare the mid-term and long-term outcomes of different options for total hip replacement in patients with consequences of severe acetabular fractures and pelvic discontinuity and to make mathematical models of such.

Methods: 150 patients with consequences of severe acetabular fractures and pelvic discontinuity were divided into four groups according to the technique used for total hip arthroplasty from 2004 to 2016. Each patient was clinically and radiologically evaluated (including CT scans) post-operatively. Functional outcomes were evaluated using standard questioners.

Results: Mathematical models showed that Burch-Schneider Reinforcement Cage is the most effective option for creation of primary stability of acetabular component in patients with consequences of severe acetabular fractures and pelvic discontinuity. This was also shown by better functional outcomes in the group of patients with this option used during total hip arthroplasty.

Conclusions: Combining Burch-Schneider Reinforcement Cage with the acetabular component in total hip arthroplasty in patients with such pathology is preferable to create primary stability. Algorithms were created to minimize the cost of pre-operative planning and to increase the functional outcomes of total hip replacement in patients with consequences of severe acetabular fractures and pelvic discontinuity.
