A previously healthy 17-year-old patient presented to our institution with a 5-week history of left hip and knee pain in the absence of any trauma. Pelvic radiograph revealed a subacute left femoral neck fracture. He subsequently underwent surgical fixation and made an uneventful recovery. Further endocrine evaluation revealed isolated vitamin D deficiency to be the likely underlying cause for this fracture. Multiple previous opportunities were missed to identify the cause for this patient's symptoms. An intracapsular fracture in a young adult requires early recognition and prompt anatomical reduction. This case emphasises the need to maintain a high index of suspicion for atraumatic fractures in healthy adolescents with unexplained joint pain. Further endocrine and metabolic investigations are warranted, and isolated vitamin D deficiency must be considered as a potential causative factor.<\/jats:p>","DOI":"10.1136\/bcr-2017-219385","type":"journal-article","created":{"date-parts":[[2017,4,6]],"date-time":"2017-04-06T09:10:13Z","timestamp":1491469813000},"page":"bcr-2017-219385","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["A
