Internal fixation is a common surgical treatment indicated for several fractures, yet there are few comprehensive epidemiological studies describing mortality following the procedure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Data were extracted from an England-wide administrative database (Hospital Episode Statistics, HES) and linked to mortality records from the Office for National Statistics (ONS). All records from patients aged 18 years or older who were admitted due to a non-polytrauma single fracture and underwent internal fixation between 2013 and 2023 were included. Crude and adjusted mortality rates were calculated as well as the restricted mean time lost.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 630\u2009758 admissions were included in the primary analysis. Of these, 55% were female, and the mean\u00b1SD\u2009age was 59\u00b123 years. Primary open reduction internal fixation was the most common procedure (54% of cases), followed by closed reduction internal fixation (35%). Overall, mortality rates following internal fixation were 2% within 30 days, 5% within 90 days and 10% within 365 days. Mortality rates were described by fracture region and reduction procedure. Variation in mortality rates across fracture regions and procedures was attenuated in the case-mix-adjusted estimates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study described national crude and adjusted mortality rates following internal fixation for the treatment of skeletal fractures.
