Extensive type IIIB bone loss of the acetabulum and suitability of 3D printings during planning

Abstract

Introduction. Despite the advances made in medicine, arthroplasty performed in young patients is still associated with an increased risk of complications. Massive destruction of the acetabular ring is a challenge, requires careful planning, and the use of various surgical techniques and implants. Case Report. The case is presented of a young woman with a Paprosky type IIIB defect of the acetabular rin who underwent a revision total hip arthroplasty. During planning, 3D printed bone models were used because the choice of surgical technique was not obvious. The 3D prints, together with the radiological diagnostics performed, provided a real picture of the problem, and a better understanding of the pathoanatomy. Conclusions. Multiple, unpunished trialing on printed models by using different trial implants make it possible to test the feasibility and practice the techniques. It may prevent making the mistake of choosing wrong the surgical technique. Additionally, the models give better visualization of the patient's anatomy during the surgery lifetime.
