The best option for the \u201ctreatment\u201d of dislocation of the hip endoprosthesis is to prevent the development of primary instability. There are cases in which even with the correct installation of the endoprosthesis components, dislocations arise due to the weakness or defect of the capsular\u2013ligament apparatus. Currently, many methods have been developed to strengthen and restore the posterior structures of the capsule of the hip joint with the help of auto- and allomaterials, which differ in both the fixation technique and the characteristics of the materials themselves. In this paper, we propose a method for restoring and strengthening the posterior structures of the capsule of the hip joint using polypropylene-based graft implants. The purpose of this study is to, with the help of specialized software, build a model of the capsule of the hip joint after capsulotomy and to determine the stiffness capabilities of the defect covered with polypropylene mesh.<\/jats:p><jats:p>\n          Results\u2003The study was performed using a software package based on the finite-element method. As a result of the performed calculations, pictures of the distribution of the stress\u2013strain state in the \u201chead-capsule\u201d system were obtained. To assess the effectiveness of the method of closing the capsule, from the viewpoint of rigidity, as the main characteristics, the values of the opening of the cut are selected.<\/jats:p><jats:p>\n          Conclusions\u2003Under the kinematic loading of the model, the smallest values of the opening of the section are obtained when it is closed by a grid. In the case of thread fixation, the values were higher by 8.5%. However, the values of equivalent stresses, both in the capsule and in the head, in the model with the grid turned out to be the largest. These stresses were higher by 23.8% in the capsule and by 60.4% in the head than the same values for the thread fixation model. The obtained results indicate that the model with a grid is more rigid in the considered fixation variants.<\/jats:p>","DOI":"10.1055\/s-0039-3402793","type":"journal-article","created":{"date-parts":[[2020,1,22]],"date-time":"2020-01-22T00:03:20Z","timestamp":1579651400000},"page":"e11-e18","source":"Crossref","is-referenced-by-count":1,"title":["Biomechanical Substantiation of the Strength and Stiffness of a Hip Joint Capsule Defect Fixation with Polypropylene Mesh"],"prefix":"10.1055","volume":"06","author":[{"given":"Serhii Olegovich","family":"Maslennikov","sequence":"additional","affiliation":[{"name":"Department of Traumatology and Orthopaedics, Zaporizhia State Medical University, Zaporozhye, St. Steshenko, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Serhii Pavlovich","family":"Panchenko","sequence":"additional","affiliation":[{"name":"Department of Structural Mechanics and Strength of Materials, State Higher Educational Institution, Prydniprovska State Academy of Civil Engineering and Architecture, Dnipro, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maxim Leonidovich","family":"Golovakha","sequence":"additional","affiliation":[{"name":"Department of Traumatology and Orthopaedics, Zaporizhia State Medical University, Zaporozhye, St. Steshenko, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2020,1,21]]},"container-title":["The Surgery Journal"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0039-3402793.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,1,22]],"date-time":"2020-01-22T00:03:21Z","timestamp":1579651401000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0039-3402793"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,1]]},"references-count":0,"journal-issue":{"issue":"01","published-online":{"date-parts":[[2019,12,2]]},"published-print":{"date-parts":[[2020,1]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0039-3402793","relation":{},"ISSN":["2378-5128","2378-5136"],"issn-type":[{"value":"2378-5128","type":"print"},{"value":"2378-5136","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,1]]}}}
