The most common idiopathic HOA is generally a diagnosis of exclusion, with pathogenetic mechanisms largely still misunderstood. We aimed to investigate the correlation between femoral\u2013acetabular and spinopelvic anatomical and computed tomography (CT) characteristics, and the presence of primary OA. Methods: We retrospectively analyzed CT scans from 2019 to 2021, excluding patients under 45 years or with conditions affecting the pelvis, sacrum, or lower limbs. Femoral, acetabular, and spinopelvic parameters were measured; signs of OA were analyzed in the hip and knee joints. Patients were categorized into two groups: A (isolated hip OA) and B (no OA); patients with hip OA, also presenting knee OA, were excluded from this study. Results: In total, 232 cases were examined; statistical analyses compared CT parameters between 129 subjects from Group A and 103 patients of Group B. Group A showed a mean femoral version of 16 \u00b1 4.53 degrees, significantly higher than Group B\u2019s 13.16 \u00b1 4.37 degrees (p = 0.0001). Other parameters showed no significant differences. Conclusion: This study highlights an association between femoral version and primary hip OA.<\/jats:p>","DOI":"10.3390\/jpm14091004","type":"journal-article","created":{"date-parts":[[2024,9,23]],"date-time":"2024-09-23T03:36:38Z","timestamp":1727062598000},"page":"1004","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Unveiling the Hidden Links: Anatomical and Radiological Insights into Primary Hip Osteoarthritis"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0215-7805","authenticated-orcid":false,"given":"Valerio","family":"Tiburzi","sequence":"first","affiliation":[{"name":"Clinical Ortopaedics, Department of Clinical and Molecular Sciences, Politecnica University of Marche, 60126 Ancona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlo","family":"Ciccullo","sequence":"additional","affiliation":[{"name":"Clinical Ortopaedics, Department of Clinical and Molecular Sciences, Politecnica University of Marche, 60126 Ancona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luca","family":"Farinelli","sequence":"additional","affiliation":[{"name":"Clinical Ortopaedics, Department of Clinical and Molecular Sciences, Politecnica University of Marche, 60126 Ancona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0906-4647","authenticated-orcid":false,"given":"Marco","family":"Di Carlo","sequence":"additional","affiliation":[{"name":"Rheumatology Unit, Department of Clinical and Molecular Sciences, Politecnica University of Marche, Ospedale \u201cCarlo Urbani\u201d\u2014AST Ancona, 60035 Jesi, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fausto","family":"Salaffi","sequence":"additional","affiliation":[{"name":"Rheumatology Unit, Department of Clinical and Molecular Sciences, Politecnica University of Marche, Ospedale \u201cCarlo Urbani\u201d\u2014AST Ancona, 60035 Jesi, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6874-4941","authenticated-orcid":false,"given":"Francesca","family":"Bandinelli","sequence":"additional","affiliation":[{"name":"Department, Santa Maria Nuova Hospital, Usl Tuscany Center, 50122 Florence, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio Pompilio","family":"Gigante","sequence":"additional","affiliation":[{"name":"Clinical Ortopaedics, Department of Clinical and Molecular Sciences, Politecnica University of Marche, 60126 Ancona, Italy"},{"name":"IRCCS INRCA, 60126 Ancona, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1172","DOI":"10.1002\/art.42089","article-title":"Prevalence Trends of Site-Specific Osteoarthritis From 1990 to 2019: Findings from the Global Burden of Disease Study 2019","volume":"74","author":"Long","year":"2022","journal-title":"Arthritis Rheumatol."},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Eitner, A., Sparing, S., Kohler, F.C., M\u00fcller, S., Hofmann, G.O., Kamradt, T., Schaible, H.-G., and Aurich, M.
