When No One Can Explain How the Hip Broke
Sometimes a resident is found in pain, or an X-ray shows a fracture, and no fall was seen or charted. Federal rules use the phrase injury of unknown source for situations like this, and they treat it seriously.
Under 42 C.F.R. § 483.12(c), in response to allegations of abuse, neglect, exploitation or mistreatment, the facility must ensure that all alleged violations, "including injuries of unknown source," are reported to the administrator and to other officials, including the State Survey Agency and adult protective services where state law gives them jurisdiction over long-term care facilities, in accordance with state law. The timing is set by the rule: immediately, but not later than 2 hours after the allegation is made, if the events involve abuse or result in serious bodily injury, or not later than 24 hours if they do not involve abuse and do not result in serious bodily injury.
The rule does not stop at the report. The facility must have evidence that all alleged violations are thoroughly investigated, must prevent further potential abuse, neglect, exploitation or mistreatment while the investigation is in progress, and must report the results to the administrator or a designated representative and to other officials under state law, including the State Survey Agency, within 5 working days of the incident. If the alleged violation is verified, appropriate corrective action must be taken.
This matters most when the resident cannot explain what happened, for example because of confusion or memory loss. An unexplained fracture raises real questions about supervision and record-keeping, but the label "unknown source" describes a gap in the account, not a finding. What fills that gap is what the records and witnesses show.
If you are looking at an unexplained fracture, the records that usually matter include the facility's incident report, the resident's care plan and fall-risk assessments, nursing notes from the shifts before and after, and any report or investigation the facility made under this rule. A conversation with our attorney can help you understand what those documents say and what they leave unanswered; you can request a case evaluation when you are ready.
