A substantial proportion of patients requiring these revision procedures present with major bone deficits and extensive osteolysis. In light of these challenges, this study aims to provide a comprehensive comparison between two commonly utilized methods: trabecular titanium shell implants and Burch\u2013Schneider acetabular reinforcement cages. Methods: Participants of both sexes were included through a retrospective review of medical records. The sole inclusion criterion was that the patient had undergone revision hip arthroplasty using either Burch\u2013Schneider acetabular reinforcement cages or Regenerex trabecular titanium shell within the past 18 years. No exclusion criteria were applied concerning patient age, laterality, ethnicity, or post-operative status. Each patient was evaluated based on nine predictive factors, including the Paprosky classification, duration of surgery, perioperative blood loss, number of bone grafts and screws used, as well as pre- and post-operative Harris Hip Score (HHS) and Visual Analogue Scale (VAS). Results: A total of 220 patients were included in the analysis, with 75% (n = 165) comprising the group treated with trabecular titanium implants and 25% (n = 55) treated with Burch\u2013Schneider cages. The use of Regenerex trabecular titanium was associated with a 32.40% (n = 23.13 mL) reduction in bone graft tissue required and a 13.7% (n = 0.59) increase in the number of screws needed. Additionally, the trabecular titanium group experienced a 15.93% (n = 179.64 mL) reduction in perioperative blood loss compared to the Burch\u2013Schneider cage group. The other parameters analyzed in the study did not demonstrate statistical significance. Conclusions: The use of a trabecular titanium acetabular shell may be an effective option, particularly in patients with severe acetabular deficits, as it provides favorable clinical and radiological outcomes. Additionally, it reduces the number of bone grafts required and allows for faster and more immediate partial weight-bearing on the operated limb.<\/jats:p>","DOI":"10.3390\/jcm14124381","type":"journal-article","created":{"date-parts":[[2025,6,19]],"date-time":"2025-06-19T09:57:48Z","timestamp":1750327068000},"page":"4381","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Comparison of the Trabecular Titanium Acetabular Shell with Burch\u2013Schneider Cages in Revision Hip Arthroplasty"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2427-974X","authenticated-orcid":false,"given":"Pawel","family":"Kami\u0144ski","sequence":"first","affiliation":[{"name":"Andrzej Frycz Modrzewski University, 30-705 Krakow, Poland"},{"name":"Malopolan Orthopaedic and Rehabilitation Hospital, Aleja Modrzewiowa 22, 30-224 Krakow, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaros\u0142aw","family":"Ambro\u017cy","sequence":"additional","affiliation":[{"name":"Malopolan Orthopaedic and Rehabilitation Hospital, Aleja Modrzewiowa 22, 30-224 Krakow, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5883-5551","authenticated-orcid":false,"given":"Rafa\u0142","family":"Obuchowicz","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Imaging, Jagiellonian University Medical College, 30-663 Krakow, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,19]]},"reference":[{"key":"ref_1","unstructured":"(2025, April 05).
