Advances in three-dimensional printing technology (3DP) have afforded to the surgeons to create a patient-specific implant matching the morphology and topography of the defect. OBJECTIVE: The aim of the current research was to determine the survivorship in the treatment of acetabular bone defects with pelvic discontinuity (PD). METHODS: In order to reconstruct Paprosky type III defects with PD, twenty-three patients underwent revision total hip arthroplasty (THA) utilizing 3D-printed implants (Mobelife). The primary outcomes were the implant-associated failure rate correlated with survivorship. As secondary variables, complications and the effect of age, sex, comorbidities, history of infections and the presence of other lower limb arthroplasties on a new revision were analyzed. RESULTS: Patients were followed out to a mean of 67.22 \u00b1 39.44 months (range, 0.9\u2013127 months). Mobelife implant mean survival was 102.57 \u00b1 9.90 months (95% CI 83.17\u2013121.96). The cohort\u2019s implant one-year survival rate was 87%; at ten years, it dropped to 78.3%. There were four revisions: three due to periprosthetic joint infection (PJI) and one case due to aseptic loosening. Cox regression analysis did not identify any variable as predictor of failure. CONCLUSION: The use of 3DP patient-specific acetabular components has shown encouraging results and it is a viable treatment option for addressing acetabular defects with combined PD in aseptic THA revision.<\/jats:p>","DOI":"10.3233\/thc-231647","type":"journal-article","created":{"date-parts":[[2024,3,1]],"date-time":"2024-03-01T11:18:55Z","timestamp":1709291935000},"page":"3783-3792","source":"Crossref","is-referenced-by-count":4,"title":["Survival analysis of 3D printed acetabular implants in revision total hip arthroplasty associated with severe pelvic discontinuities"],"prefix":"10.1177","volume":"32","author":[{"given":"Ainhoa","family":"\u00c1lvarez Valdivielso","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Helios ENDO-Klinik Hamburg, Hamburg, Germany"},{"name":"Department of Traumatology and Orthopaedic Surgery, Hospital Universitario Son Espases, Palma de Mallorca, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mustafa","family":"Akkaya","sequence":"additional","affiliation":[{"name":"Ankara Yildirim Beyazit University, Ankara City Hospital, Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans","family":"Mau","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Helios ENDO-Klinik Hamburg, Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.
