We enrolled 34 patients, including 11 with humerus midshaft fractures, 12 with tibia plateau fractures, 2 with pilon fractures, and 9 with acetabulum fractures. The entire process of plate contouring over the 3DP model was videotaped and retrospectively analyzed. The total time and number of trials for the intraoperative positioning of precontoured plates and any further intraoperative contouring events were prospectively recorded. The mismatch between the planned and postoperative plate positions was evaluated. The average plate contouring time was 9.2 min for humerus shaft, 13.8 min for tibia plateau fractures, 8.8 min for pilon fractures, and 11.6 min for acetabular fractures. Most precontoured plates (88%, 30\/34) could sit on the planned position without mismatch. In addition, only one patient with humerus shaft fracture required additional intraoperative contouring. Preoperative patient specific periarticular plate contouring using a 3DP model is a simple and efficient method that may alleviate the surgical challenges involved in plate contouring and positioning.<\/jats:p>","DOI":"10.3390\/jpm13071145","type":"journal-article","created":{"date-parts":[[2023,7,17]],"date-time":"2023-07-17T00:35:04Z","timestamp":1689554104000},"page":"1145","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["The Clinical Efficacy of Contouring Periarticular Plates on a 3D Printed Bone Model"],"prefix":"10.3390","volume":"13","author":[{"given":"Seung-yeob","family":"Sakong","sequence":"first","affiliation":[{"name":"Department of Orthopaedic SurgeryAjou University Hospital, Ajou University College of Medicine, Suwon 16499, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jae-Woo","family":"Cho","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Korea University Guro Hospital, Seoul 08308, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beom-Soo","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Keimyung University Dongsan Hospital, Keimyung University Medicine, Daegu 41931, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung-Jun","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Korea National University of Transportation, Chungbuk 27469, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8095-6173","authenticated-orcid":false,"given":"Eic-Ju","family":"Lim","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Chungbuk National University Hospital, Chungbuk National University College of Medicine, Cheongju 28644, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jong-Keon","family":"Oh","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Korea University Guro Hospital, Seoul 08308, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1116","DOI":"10.1097\/00005373-198612000-00011","article-title":"Delayed wound healing, infection, and nonunion following open reduction and internal fixation of tibial plafond fractures","volume":"26","author":"Dillin","year":"1986","journal-title":"J.
