الوصف: | Objective Management of extensive acetabular bone defects in total hip arthroplasty (THA) remains challenging. This study aims to investigate the feasibility and preliminary outcomes of 3D‐printed personalized porous acetabular components for the reconstruction of acetabular defects in primary THA. Methods This retrospective study involved seven patients who received 3D‐printed acetabular components in primary THA between July 2018 and March 2021. Preoperatively, acetabular bone defects were evaluated by referencing the Paprosky classification. There were two "Paprosky type IIIA" defects and five "Paprosky type IIIB" defects. The acetabular components were custom‐made for each patient to reconstruct the extensive acetabular defects. The hip function was assessed according to the Harris hip score (HHS). Clinical and radiographic outcomes were assessed. Results The average follow‐up period was 40 months, ranging from 26 to 57 months. There were no patients lost to follow‐up. The HHS improved from 44 (range: 33–53) before the operation to 88 (range: 79–93) at the final follow‐up. Postoperative X‐rays showed that the 3D‐printed personalized components were properly fitted with the acetabulum. The average center of rotation (COR) discrepancy was 2.3 mm horizontally and 2.1 mm vertically, respectively. Tomosynthesis‐Shimadzu metal artifact reduction technology images showed that the implant was in close contact with the host bone. Moreover, no complications were observed during the follow‐up period, including loosening, dislocation, or component protrusion. Conclusion The implantation of 3D‐printed personalized acetabular components showed accurate reconstruction, stable mechanical support, and favorable function at short‐term follow‐up. This may be a viable alternative method for reconstructing extensive acetabular defects in THA. |
