Traditional versus mirror three-dimensional printing technology for isolated acetabular fractures: a retrospective study with a median follow-up of 25 months

Abstract

Objective To assess the outcomes of traditional three-dimensional (3D) printing technology (TPT) versus mirror 3D printing technology (MTT) in treating isolated acetabular fractures (IAFs). Methods Consecutive patients with an IAF treated by either TPT or MTT at our tertiary medical centre from 2012 to 2018 were retrospectively reviewed. Follow-up was performed 1, 3, 6, and 12 months postoperatively and annually thereafter. The primary outcome was the Harris hip score (HHS), and the secondary outcomes were major intraoperative variables and key orthopaedic complications. Results One hundred fourteen eligible patients (114 hips) with an IAF (TPT, n = 56; MTT, n = 58) were evaluated. The median follow-up was 25 months (range, 21–28 months). At the last follow-up, the mean HHS was 82.46 ±14.70 for TPT and 86.30 ± 13.26 for MTT with a statistically significant difference. Significant differences were also detected in the major intraoperative variables (operation time, intraoperative blood loss, number of fluoroscopic screenings, and anatomical reduction number) and the major orthopaedic complications (loosening, implant failure, and heterotopic ossification). Conclusion Compared with TPT, MTT tends to produce accurate IAF reduction and may result in better intraoperative variables and a lower rate of major orthopaedic complications.

Experimental study on the biomechanical stability of complex acetabular fractures in the quadrilateral area: application of a dynamic anterior titanium-plate screw system

“…Single-center series suggest that 12–45% of acetabular fracture patients treated with open reduction internal fixation subsequently undergo at least one secondary surgical procedure that ablates the repaired native acetabulum [ 17 ]. Therefore, some authors have claimed that a minimally invasive percutaneous technique should be encouraged, and a single forward approach should be adopted for complex fractures of the acetabulum during surgery [ 18 , 19 ]. We also found that the ilioinguinal approach provided a good view of fractures of the quadrilateral area and the partial posterior column.…”

“…Las simulaciones realizadas sobre las imágenes especulares de la hemipelvis sanas parecen estar relacionadas con una mejor reducción postoperatoria en comparación con aquellas simulaciones realizadas únicamente con la hemipelvis fracturada. 196,197 Aunque con menor utilidad desde el punto de vista del autor de esta tesis, puede imprimirse la simulación virtual de la placa de osteosíntesis para facilitar el premoldeado posterior, si bien resulta menos eficiente desde el punto de vista de dificultad de la impresión y posibilidad de errores. 198 Localización: Pelvis Sección:…”
