Use of customized acetabular components for hip joint arthroplasty in posttraumatic coxarthrosis

Introduction The increase in the number of primary hip joint arthroplasties leads to a steady increase in revision interventions. The category of complex arthroplasty also includes patients with extensive acetabular injuries due to high-energy trauma. Amplification of clinical cases requires an individual approach when planning the configuration of the acetabular component. In recent years, clinics have been actively introducing into practice the technology of 3D-modeling of hip replacement components. The purpose of the study was to assess the short and medium-term results of hip joint arthroplasty in posttraumatic coxarthrosis with significant bone defects, using individual acetabular components, with the presentation of clinical cases. Material was five arthroplasty cases operated using customized implants produced with a 3D printer. All five patients were males of working age who suffered high-energy injuries. Three of them had previous operations on the hip joint (from 1 to 5 operations)...
