Although several successful solutions have been raised, their efficacy and reliability have not been fully substantiated. This work aims to present a simple, economic and effective acetabular reconstructive technique to resolve the massive acetabular bone defect in DDH scenario.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This is a case series and observational study investigating the effectiveness and safety of extra\u2010articular blocking technique in patients diagnosed as DDH of Crowe type II\u2010III and Hartofilakidis B. Sixteen consecutive patients indicated for extra\u2010articular blocking and treated with total hip arthroplasty were enrolled in this series from January 2019 to August 2020. The outcome measures included the surgical indicators such as acetabular coverage, prosthesis position, operational time, medical cost, and short\u2010term follow\u2010up indicators such as complications profile, patient\u2010reported functional scales, overall recovery after surgery, and radiographic bone integration and remodeling. Their medical documentation and follow\u2010up records were carefully reviewed with ethical approval.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean values of postoperative acetabular component inclination and anteversion were 42.3\u00b0\u2009\u00b1\u20092.1\u00b0 and 16.4\u00b0\u2009\u00b1\u20091.8\u00b0, with an average acetabular coverage of 92.1%. The mean cost reduction for patients treated with this technique compared with those treated with trabecular metal augmentation was 15.3%. The mean time until walking under full\u2010weight bearing decreased by 3.5\u2009weeks compared with patients treated with autologous bone grafting. Within an average observational period of 18\u00a0months, the mean improvements in Harris hip score and WOMAC score were 31 and 22 points, respectively, which were identical to those with bone graft and metal augmentation techniques. No complications such as dislocation, acetabular loosening, periprosthetic joint infection, and limb length discrepancy were recorded. No signs of translucent line formation, third\u2010party reaction, and wear\u2010associated osteolysis were identified.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The extra\u2010articular blocking can work simply and effectively to address acetabular bone defect in DDH patients of Crowe II\u2013III and Hartofilakidis B, as evidenced by cost\u2010effectiveness and instant weight\u2010bearing advantages, low failure rate, and early osteointegration and remodeling.<\/jats:p><\/jats:sec>","DOI":"10.1111\/os.13688","type":"journal-article","created":{"date-parts":[[2023,2,27]],"date-time":"2023-02-27T09:48:42Z","timestamp":1677491322000},"page":"1187-1195","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Extra\u2010articular Blocking Technique to Resolve Severe Acetabular Bone Defect in Developmental Dysplasia of the Hip"],"prefix":"10.1111","volume":"15","author":[{"given":"Zhonghua","family":"Xu","sequence":"first","affiliation":[{"name":"Joint Disease &amp;
