Materials and Methods: Firstly, the length of the pubic region, quadrilateral region, iliac region, and the total length of the DAPSQ trajectory were measured by a digital measurement approach in 22 complete pelvic specimens. Then, the results were compared with the direct measurement of pelvic specimens to verify the reliability of the digital measurement method. Secondly, 504 cases (834 hemilateral pelvis) of adult pelvic CT images were collected from four medical centers in China. The four DAPSQ trajectory parameters were obtained with the digital measurement method. Finally, the third-generation DAPSQ plate was designed, and its applicability was verified. Results: There was no statistically significant difference in the four trajectory parameters when comparing the direct measurement method with the digital measurement method (p &gt; 0.05). The average lengths of the pubic region, quadrilateral region, iliac region, and the total length in Chinese population were (60.96 \u00b1 5.39) mm, (69.11 \u00b1 5.28) mm, (84.40 \u00b1 6.41) mm, and (214.46 \u00b1 10.15) mm, respectively. Based on the measurement results, six models of the DAPSQ plate including small size (A1,A2), medium size (B1,B2), and the large size (C1,C2) were designed. The verification experiment showed that all these six type plates could meet the requirement of 94.36% cases. Conclusions: A reliable computerized method for measuring irregular pelvic structure was proposed, which not only provided an anatomical basis for the design of the third-generation DAPSQ plate, but also provided a reference for the design of other pelvic fixation devices.<\/jats:p>","DOI":"10.3390\/medicina59020211","type":"journal-article","created":{"date-parts":[[2023,1,23]],"date-time":"2023-01-23T02:27:45Z","timestamp":1674440865000},"page":"211","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Third-Generation Dynamic Anterior Plate-Screw System for Quadrilateral Fractures: Digital Design Based on 834 Pelvic Measurements"],"prefix":"10.3390","volume":"59","author":[{"given":"Ranran","family":"Shang","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Wuhan Hospital of Integrated Traditional Chinese and Western Medicine, No.215 Zhongshan Avenue, Wuhan 430031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3215-1626","authenticated-orcid":false,"given":"Haiyang","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Clinical Medicine, Graduate School of Tianjin Medical University, No.22 Qixiangtai Road, Tianjin 301700, China"},{"name":"Duke Molecular Physiology Institute, Duke University School of Medicine, Duke University, Durham, NC 27708, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, Wuhan Hospital of Integrated Traditional Chinese and Western Medicine, No.215 Zhongshan Avenue, Wuhan 430031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chengjing","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, The Fifth People\u2019s Hospital of Huaian, Xiangjiang Road, Huaian 223002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qipeng","family":"Shao","sequence":"additional","affiliation":[{"name":"Department of Joint Surgery, People\u2019s Hospital of Ganzhou, No.16 Mei Guan Avenue, Ganzhou 341000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ximing","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, General Hospital of Central Theater Command, No.627 Wuluo Road, Wu Chang District, Wuhan 430030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xianhua","family":"Cai","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Huanan Hospital, Shenzhen University, No.1 Fuxin Road, Shenzhen 518060, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"23","DOI":"10.1590\/S0102-36162011000100004","article-title":"Epidemiological analysis on acetabular fractures","volume":"46","author":"Maia","year":"2015","journal-title":"Rev.
