Patients frequently have various complications, such as avascular necrosis, during the recovery period. Reasonable rehabilitation training after surgery is necessary for patient rehabilitation. Multiple studies have proved a relationship between bone growth repair and blood vessel growth, and the blood supply system provides various oxygen and nutrients for bone remodeling to promote the smooth progress of bone remodeling. As a new therapeutic method, electrical stimulation has been widely used in osteoporosis, bone nonunion, and other diseases, and has achieved good therapeutic effects. Therefore, the internal fixation model of femoral neck fracture was established in this paper, and the influence of load training on postoperative rehabilitation was discussed. At the same time, the blood supply system was coupled with bone remodeling analysis, and electrical stimulation was added to investigate the change in bone density. The simulation results demonstrate a novel method for simulating bone remodeling during postoperative rehabilitation that incorporates electrical stimulation. In this method, mechanical loading promotes an increase in bone density; the addition of angiogenic factors leads to a diminished increase in bone density, whereas the inclusion of electrical stimulation results in an enhanced increase in bone density.<\/jats:p>","DOI":"10.1002\/cnm.70199","type":"journal-article","created":{"date-parts":[[2026,7,15]],"date-time":"2026-07-15T02:31:08Z","timestamp":1784082668000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Numerical Analysis of Postoperative Rehabilitation of Femoral Neck Fracture: Coupling of Vascular Growth, Bone Remodeling, and the Effect of Electrical Stimulation"],"prefix":"10.1002","volume":"42","author":[{"given":"Qian","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Mechanics, School of Mechanical Engineering Tianjin University  Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7249-9440","authenticated-orcid":false,"given":"Chuanyong","family":"Qu","sequence":"additional","affiliation":[{"name":"Department of Mechanics, School of Mechanical Engineering Tianjin University  Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,14]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1186\/1754\u20109493\u20104\u201016"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.2147\/CIA.S363682"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12891\u2010023\u201006455\u20101"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00198\u2010019\u201004944\u20105"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports\u20102014\u2010094465"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.blo.0000128296.28666.35"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.51542\/ijscia.v6i1.19"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcms.2005.02.004"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.152324099"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1172\/JCI82585"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1210\/endo.143.4.8719"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41536\u2010023\u201000288\u20101"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598\u2010019\u201053249\u20104"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.1039\/c5tb00637f"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.mser.2024.100801"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.matchemphys.2023.127960"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bioadv.2023.213285"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1002\/jcp.26143"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bioadv.2022.212918"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.1002\/jor.22595"},{"key":"e_1_2_10_22_1","doi-asserted-by":"publisher","DOI":"10.3390\/cells11172650"},{"key":"e_1_2_10_23_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsami.3c09428"},{"key":"e_1_2_10_24_1","doi-asserted-by":"publisher","DOI":"10.3389\/fbioe.2022.832808"},{"key":"e_1_2_10_25_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jot.2024.06.009"},{"key":"e_1_2_10_26_1","doi-asserted-by":"publisher","DOI":"10.3390\/jcm12051866"},{"key":"e_1_2_10_27_1","doi-asserted-by":"publisher","DOI":"10.1155\/2020\/6849352"},{"key":"e_1_2_10_28_1","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000027379"},{"key":"e_1_2_10_29_1","doi-asserted-by":"publisher","DOI":"10.1109\/RBME.2018.2799189"},{"key":"e_1_2_10_30_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmbbm.2016.08.026"},{"key":"e_1_2_10_31_1","doi-asserted-by":"publisher","DOI":"10.1016\/0021\u20109290(94)90049\u20103"},{"key":"e_1_2_10_32_1","volume-title":"Research and Application of Computational Model of Osteoporosis of Cancellous Bone Conforming to Physiological Process","author":"Zhang H.","year":"2005"},{"key":"e_1_2_10_33_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsabm.2c00321"},{"key":"e_1_2_10_34_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2009.08.012"},{"key":"e_1_2_10_35_1","doi-asserted-by":"publisher","DOI":"10.1016\/s0021\u20109290(00)00221\u20109"},{"key":"e_1_2_10_36_1","volume-title":"Study on Theory and Method of Numerical Simulation of Bone Reconstruction in Weightless Environment","author":"Lei Z.
