Traumatic periprosthetic acetabular fractures after total hip arthroplasty (THA) are rare and particularly challenging because treatment must simultaneously address fracture stability and acetabular component stability.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>A 72-year-old woman sustained a high-energy road-traffic injury from an outside vehicle 10 years after left THA. Computed tomography (CT) demonstrated a comminuted both-column acetabular fracture with medial displacement of the quadrilateral surface and compromised periacetabular bone continuity, raising concern for cup instability. Open reduction and internal fixation (ORIF) was performed in the supine position through a lateral rectus abdominis approach (LRAA). Intraoperative direct visualization and fluoroscopy confirmed a well-fixed, osseointegrated acetabular cup, which was therefore retained. The anterior and posterior columns and quadrilateral surface were reconstructed using two contoured reconstruction plates, with careful screw trajectory planning to avoid the cup.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>For traumatic periprosthetic both-column acetabular fractures after THA, intraoperative assessment of acetabular component stability is pivotal. When the cup is stable, LRAA can provide direct intrapelvic exposure enabling anatomic reduction and robust buttress fixation of the quadrilateral surface while avoiding revision arthroplasty.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fsurg.2026.1794712","type":"journal-article","created":{"date-parts":[[2026,4,23]],"date-time":"2026-04-23T05:37:58Z","timestamp":1776922678000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Lateral rectus abdominis approach fixation of a high-energy both-column acetabular fracture after total hip arthroplasty with retention of a stable acetabular cup: a case report"],"prefix":"10.3389","volume":"13","author":[{"given":"Xiangyu","family":"Zong","sequence":"first","affiliation":[{"name":"Knee Preservation Center, The Affiliated Hospital of Qingdao University, Qingdao","place":["Shandong, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qicai","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Joint Surgery, The Affiliated Hospital of Qingdao University, Qingdao","place":["Shandong, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chunpu","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, Qingdao Hospital, University of Health and Rehabilitation Sciences (Qingdao Municipal Hospital), Qingdao","place":["Shandong, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongtao","family":"Ge","sequence":"additional","affiliation":[{"name":"Department of Spine Surgery, The Affiliated Hospital of Qingdao University, Qingdao","place":["Shandong, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuemei","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Operating Room, Qilu Hospital (Qingdao), Cheeloo College of Medicine, Shandong University, Qingdao","place":["Shandong, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yingze","family":"Zhang","sequence":"additional","affiliation":[{"name":"Knee Preservation Center, The Affiliated Hospital of Qingdao University, Qingdao","place":["Shandong, China"]},{"name":"Department of Trauma Emergency Center, The Third Hospital of Hebei Medical University","place":["Hebei Shijiazhuang, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tianrui","family":"Wang","sequence":"additional","affiliation":[{"name":"Knee Preservation Center, The Affiliated Hospital of Qingdao University, Qingdao","place":["Shandong, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,4,23]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"752","DOI":"10.1007\/s43465-021-00593-1","article-title":"Management and outcomes of bilateral acetabular fractures: a critical review of the literature","volume":"56","author":"Mousafeiris","year":"2022","journal-title":"Indian J Orthop"},{"key":"B2","doi-asserted-by":"publisher","first-page":"297","DOI":"10.1308\/003588414X13814021680157","article-title":"Low energy fractures of the acetabulum","volume":"96","author":"Papadakos","year":"2014","journal-title":"Ann R Coll Surg Engl"},{"key":"B3","doi-asserted-by":"publisher","first-page":"e204","DOI":"10.3346\/jkms.2024.39.e204","article-title":"The current incidence and future projection of acetabular fractures in Korea","volume":"39","author":"Park","year":"2024","journal-title":"J Korean Med Sci"},{"key":"B4","doi-asserted-by":"publisher","first-page":"1410","DOI":"10.1016\/j.injury.2021.03.013","article-title":"Increasing incidence of pelvic and acetabular fractures.
