We described a new method for patient\u2010specific plate preparation by using 3D\u2010printed plate template. The study aimed to assess the effectiveness and feasibility of the 3D\u2010printed plate template in patient\u2010specific plate preparation for posterior wall acetabular fractures.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A total of 65 cases of posterior wall acetabular fractures with surgical treatment from December 2012 to December 2020 were chosen. According to the different plate contouring methods, the 65 cases were divided into three groups, which were group A (21 cases), group B (20 cases), and group C (24 cases). In group A, the 3D\u2010printed plate template was used to contour the patient\u2010specific reconstruction plate before surgery, whereas the 3D\u2010printed hemipelvis model was adopted for group B. In group C, the reconstruction plate was contoured intraoperatively. Among the three groups, the instrumentation time, surgical time, blood loss, patient\u2010specific plate preparation time, complications, reduction quality, and hip function were compared. The Kruskal\u2013Wallis test was used to analyze the reduction quality and hip function among three groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In comparison with group C, patients in groups A and B were featured by obviously shorter instrumentation time (\u221222, \u221223\u2009min), shorter surgical time (\u221246, \u221244\u2009min), and less intraoperative blood loss (\u2212110, \u2212122 mL). Compared to the hemipelvis model in group B (2.29\u2009\u00b1\u20090.56 vs. 12.70\u2009\u00b1\u20093.79\u2009days), the 3D printing time for plate templates in group A was significantly shorter. The reduction quality and hip function had no obvious statistical difference among the three groups. The complication rate within group A (3\/21) and group B (3\/20) were both slightly lower than group C (5\/24), with no obvious difference.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Both the patient\u2010specific pre\u2010contoured plate fixation methods based on the 3D\u2010printed hemipelvis model and plate template can achieve satisfactory clinical efficacy, with the advantage of shorter instrumentation and surgical time, and less intraoperative blood loss. However, 3D printing of plate template is easier and less time\u2010consuming, considering the shorter time and less cost for 3D printing of physical model.<\/jats:p><\/jats:sec>","DOI":"10.1111\/os.13838","type":"journal-article","created":{"date-parts":[[2023,8,1]],"date-time":"2023-08-01T03:55:21Z","timestamp":1690862121000},"page":"2383-2392","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Three\u2010Dimensional Printed Plate Template Versus Hemipelvis Model in Patient\u2010Specific Plate Preparation for Posterior Wall Acetabular Fractures"],"prefix":"10.1111","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1346-1397","authenticated-orcid":false,"given":"Jianan","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Orthopeadics Surgery General Hospital of Central Theater Command  Wuhan China"},{"name":"The First School of Clinical Medicine Southern Medical University  Guangzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yifan","family":"Zheng","sequence":"additional","affiliation":[{"name":"Department of Orthopeadics Surgery General Hospital of Central Theater Command  Wuhan China"},{"name":"The First School of Clinical Medicine Southern Medical University  Guangzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7474-5297","authenticated-orcid":false,"given":"Wei","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Orthopeadics Surgery General Hospital of Central Theater Command  Wuhan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shenglong","family":"Qian","sequence":"additional","affiliation":[{"name":"Department of Orthopeadics Surgery General Hospital of Central Theater Command  Wuhan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Orthopeadics Surgery General Hospital of Central Theater Command  Wuhan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yipeng","family":"Cheng","sequence":"additional","affiliation":[{"name":"Department of Orthopeadics Surgery General Hospital of Central Theater Command  Wuhan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guodong","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Orthopeadics Surgery General Hospital of Central Theater Command  Wuhan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2080-6656","authenticated-orcid":false,"given":"Xianhua","family":"Cai","sequence":"additional","affiliation":[{"name":"Department of Orthopeadics Surgery General Hospital of Central Theater Command  Wuhan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ximing","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Orthopeadics Surgery General Hospital of Central Theater Command  Wuhan China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,7,31]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.G.01471"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.16.01427"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.injury.2020.06.016"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199611000-00002"},{"issue":"205","key":"e_1_2_10_6_1","first-page":"230","article-title":"Fractures of the acetabulum.
