Application and advantages of three dimensional printing technique in anteversion evaluation of total hip arthroplasty in patients with lumbar degenerative disease

Abstract

In recent years, the application of three-dimensional printing (3DP) in the field of medicine has been expanding and has become the focus of clinical research and application. The 3D reconstruction and 1:1 model can be used to analyze and evaluate the prosthesis installation before operation and improve the accuracy and clinical effect of total hip replacement. In particular, the preoperative evaluation of total hip arthroplasty (THA) in patients with spinal-pelvic sagittal plane deformity is significant. Lumbar degeneration is one of the most common spinal-pelvic sagittal plane malformations, it is difficult to determine acetabular anteversion in THA for these patients, and it is easy to cause postoperative complications. At present, 3DP has been used to determine the anteversion of THA in patients with lumbar degenerative disease, and this article reviews the research and application of 3DP in anteversion evaluation of THA for lumbar degenerative disease, as well as its clinical advantages and challenges.
