Several radiological measurements such as the T\u00f6nnis angle (acetabular index), lateral center edge angle of Wiberg, and cross-sectional imaging parameters exist to calculate hip dysplasia.<\/jats:p><jats:p>\n          Aims\u2003The aim of this article was to describe a new ancillary linear measure of ADH on cross-sectional imaging, the Birmingham Royal Orthopaedic Hospital (BROH) Femoral offset.<\/jats:p><jats:p>\n          Patients and Methods\u2003Anteroposterior radiographs of the pelvis and computed tomography imaging of 100 consecutive patients with suspected hip dysplasia were reviewed. Demographic details and clinical indications were recorded. T\u00f6nnis angle was utilized to measure hip slope on radiographs and the BROH femoral offset was calculated for each patient. Student's t-test and one-way analysis of variance (ANOVA) were performed. Intraclass correlation coefficient analysis was evaluated to assess the reliability between observers.<\/jats:p><jats:p>\n          Results\u2003There was a total of 100 patients (128 hips) included in the study (60 with normal T\u00f6nnis angle, 53 had dysplasia, and 15 had decreased T\u00f6nnis angle). The average BROH femoral offset in the dysplastic cohort was increased in comparison to the normal cohort with a statistically significant p-Value of 0.0001. The p-value was 0.00031 on ANOVA. The BROH femoral offset calculation revealed good intra- and interobserver reliability of 0.9 and 0.9, respectively.<\/jats:p><jats:p>\n          Conclusion\u2003The BROH femoral offset can be an additional index for measuring ADH that is easier to calculate, and reproducible with good intra- and inter-observer reliability on cross-sectional imaging.<\/jats:p>","DOI":"10.1055\/s-0043-1769501","type":"journal-article","created":{"date-parts":[[2023,6,16]],"date-time":"2023-06-16T23:16:35Z","timestamp":1686957395000},"page":"471-477","source":"Crossref","is-referenced-by-count":1,"title":["Birmingham Royal Orthopaedic Hospital (BROH) Femoral Offset\u2014An Ancillary Measure of Adult Dysplasia of the Hip"],"prefix":"10.1055","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4379-1266","authenticated-orcid":false,"given":"Karthikeyan P.","family":"Iyengar","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Southport & Ormskirk NHS Trust, Southport, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0342-1364","authenticated-orcid":false,"given":"John D.","family":"Fitzpatrick","sequence":"additional","affiliation":[{"name":"Department of Musculoskeletal Radiology, Royal Orthopedic Hospital, Birmingham, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michail","family":"Michalos","sequence":"additional","affiliation":[{"name":"Department of Young Adult Hip, Royal Orthopedic Hospital, Birmingham, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Callum","family":"McBryde","sequence":"additional","affiliation":[{"name":"Department of Young Adult Hip, Royal Orthopedic Hospital, Birmingham, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angelos","family":"Politis","sequence":"additional","affiliation":[{"name":"Department of Young Adult Hip, Royal Orthopedic Hospital, Birmingham, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ed","family":"Bache","sequence":"additional","affiliation":[{"name":"Department of Young Adult Hip, Royal Orthopedic Hospital, Birmingham, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Wall","sequence":"additional","affiliation":[{"name":"Department of Young Adult Hip, Royal Orthopedic Hospital, Birmingham, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7998-2980","authenticated-orcid":false,"given":"Rajesh","family":"Botchu","sequence":"additional","affiliation":[{"name":"Department of Musculoskeletal Radiology, Royal Orthopedic Hospital, Birmingham, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2023,6,16]]},"reference":[{"issue":"02","key":"ref1","doi-asserted-by":"crossref","first-page":"336","DOI":"10.1007\/s11999-016-4815-2","article-title":"The John Charnley award: redefining the natural history of osteoarthritis in patients with hip dysplasia and impingement","volume":"475","author":"C C Wyles","year":"2017","journal-title":"Clin Orthop Relat Res"},{"issue":"02","key":"ref2","doi-asserted-by":"crossref","first-page":"279","DOI":"10.1302\/0301-620X.95B2.30744","article-title":"Prevalence of radiographic findings associated with hip dysplasia in a population-based cohort of 2081 19-year-old Norwegians","volume":"95-B","author":"I\u00d8 Enges\u00e6ter","year":"2013","journal-title":"Bone Joint J"},{"issue":"01","key":"ref3","doi-asserted-by":"crossref","first-page":"63","DOI":"10.2106\/JBJS.O.00109","article-title":"Hip dysplasia in the young adult","volume":"98","author":"L Gala","year":"2016","journal-title":"J Bone Joint Surg Am"},{"issue":"02","key":"ref4","doi-asserted-by":"crossref","first-page":"211","DOI":"10.1093\/rheumatology\/keh436","article-title":"Hip dysplasia: a significant risk factor for the development of hip osteoarthritis.
