Based on a population-based cohort of 2072 healthy adolescents (58% women) we report on radiological and clinical findings suggestive of a possible previous SCFE. Common threshold values for Southwick\u2019s lateral head\u2013shaft angle (\u2265 13\u00b0) and Murray\u2019s tilt index (\u2265 1.35) were used. New reference intervals for these measurements at skeletal maturity are also presented. <\/jats:p><jats:p> At follow-up the mean age of the patients was 18.6 years (17.2 to 20.1). All answered two questionnaires, had a clinical examination and two hip radiographs. <\/jats:p><jats:p> There was an association between a high head\u2013shaft angle and clinical findings associated with SCFE, such as reduced internal rotation and increased external rotation. Also, 6.6% of the cohort had Southwick\u2019s lateral head\u2013shaft angle \u2265 13\u00b0, suggestive of a possible slip. Murray\u2019s tilt index \u2265 1.35 was demonstrated in 13.1% of the cohort, predominantly in men, in whom this finding was associated with other radiological findings such as pistol-grip deformity or focal prominence of the femoral neck, but no clinical findings suggestive of SCFE. <\/jats:p><jats:p> This study indicates that 6.6% of young adults have radiological findings consistent with a prior SCFE, which seems to be more common than previously reported. <\/jats:p><jats:p> Cite this article: Bone Joint J 2013;95-B:452\u20138. <\/jats:p>","DOI":"10.1302\/0301-620x.95b4.29910","type":"journal-article","created":{"date-parts":[[2013,3,28]],"date-time":"2013-03-28T10:38:15Z","timestamp":1364467095000},"page":"452-458","update-policy":"https:\/\/doi.org\/10.1302\/crossmark-policy","source":"Crossref","is-referenced-by-count":15,"title":["Radiological findings that may indicate a prior silent slipped capital femoral epiphysis in a cohort of 2072 young adults"],"prefix":"10.1302","volume":"95-B","author":[{"given":"T.
