Calf muscle venous thrombosis (CMVT) is among the most important medical complications after hip surgery. CMVT has been known for many years, but many opinions about the incidence and risk factors of CMVT are still controversial. The objective of this retrospective study was to investigate the incidence and associated risk factors of postoperative CMVT in patients with hip fractures. Methods: Patients with hip fractures from January 2020 to April 2022 (n = 320) at Shenzhen Second People\u2019s Hospital were recruited in this study. The personal characteristics and clinical data of CMVT and no-CMVT patients were compared and analyzed. Binary logistic regression analyses were performed to identify potential risk factors of CMVT in patients with hip fractures. Finally we performed a receiver operating characteristic (ROC) curve analysis to compare the diagnostic values of different variables. Results: The overall incidence of new-onset CMVT in patients with hip fractures was 18.75% (60 of 320). Among the 60 CMVT patients, 70% (42 of 60) were diagnosed with femoral neck fractures, 28.3% (17 of 60) with intertrochanteric fractures, and 1.7% (1 of 60) with subtrochanteric fractures. No pulmonary embolism (PE) occurred. High preoperative D-dimer (OR = 1.002, 95%CI 0.97\u20131.03), sex (OR = 1.22, 95%CI 0.51\u20132.96), the caprini score (OR = 2.32, 95%CI 1.05\u20135.16) and the waterlow score (OR = 1.077, 95%CI 0.35\u20133.36) significantly increased the risk of developing postoperative new-onset CMVT. Conclusions: CMVT has become a common clinical disease, and its harm should not be underestimated. Our study found that D-dimer, sex, the caprini score and the waterlow score were independent risk factors for postoperative CMVT. According to our clinical work, we should pay attention to identifying the risk factors of CMVT formation and targeted intervention measures to prevent new-onset CMVT.<\/jats:p>","DOI":"10.3390\/jpm13020257","type":"journal-article","created":{"date-parts":[[2023,1,30]],"date-time":"2023-01-30T04:58:25Z","timestamp":1675054705000},"page":"257","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["The Risk Factors for New-Onset Calf Muscle Venous Thrombosis after Hip Fracture Surgery"],"prefix":"10.3390","volume":"13","author":[{"given":"Qianzheng","family":"Zhuang","sequence":"first","affiliation":[{"name":"Hand and Foot Surgery Department, The First Hospital Affiliated to Shenzhen University, Shenzhen Second People\u2019s Hospital, Shenzhen 518000, China"},{"name":"Department of Bone Joint and Musculoskeletal Tumor, The First Affiliated Hospital of Shenzhen University, Shenzhen Second People\u2019s Hospital, Shenzhen 518000, China"},{"name":"Shantou University Medical College, Shantou 515041, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qifei","family":"He","sequence":"additional","affiliation":[{"name":"Department of Bone Joint and Musculoskeletal Tumor, The First Affiliated Hospital of Shenzhen University, Shenzhen Second People\u2019s Hospital, Shenzhen 518000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aobulikasimu","family":"Aikebaier","sequence":"additional","affiliation":[{"name":"Department of Bone Joint and Musculoskeletal Tumor, The First Affiliated Hospital of Shenzhen University, Shenzhen Second People\u2019s Hospital, Shenzhen 518000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenshi","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation, The First Affiliated Hospital of Shenzhen University, Shenzhen Second People\u2019s Hospital, Shenzhen 518060, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianquan","family":"Liu","sequence":"additional","affiliation":[{"name":"Hand and Foot Surgery Department, The First Hospital Affiliated to Shenzhen University, Shenzhen Second People\u2019s Hospital, Shenzhen 518000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daping","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Southern University of Science and Technology, Shenzhen 518055, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Zhang, C., Feng, J., Wang, S., Gao, P., Xu, L., Zhu, J., Jia, J., Liu, L., Liu, G., and Wang, J.
