Inclusion criteria were isolated, and operatively treated lateral malleolar fractures (ICD-10 Code S82.6 and corresponding procedure codes). Variables were sought in bivariate and multivariate analyses. A total of 6760 cases were included. By dividing the total cases arbitrarily in half, 12 HVCs (<jats:italic>n\u2009<\/jats:italic>=\u20093327, 49%) and 56 LVCs (<jats:italic>n\u2009<\/jats:italic>=\u20093433, 51%) were identified.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Patients in HVCs were younger (48 vs. 50\u00a0years old), had more comorbidities (26% vs. 19%) and had more open fractures (0.48% vs. 0.15%). Open reduction and internal fixation was the most common operative treatment at HVCs and LVCs (95% vs. 98%). A more frequent use of external fixation (2.5% vs. 0.55%) was reported at HVCs. There was no difference in mortality between treatment at HVCs and LVCs. A longer hospitalisation of 7.2\u2009\u00b1\u20095\u00a0days at HVCs vs. 6.3\u2009\u00b1\u20094.8\u00a0days at LVCs was observed. In addition, a higher rate of complications of 3.2% was found at HVCs compared to 1.9% at LVCs. The frequency of teaching operations was significantly higher at HVCs (30% vs. 26%). Teaching status had no influence on mortality or complications but was associated with a prolonged length of stay and operating time.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>We found significant differences between HVCs and LVCs in terms of in-hospital outcomes for ankle fractures. These differences could be explained due to a more severely ill patient population and more complex (also open) fracture patterns with resulting use of external fixation and longer duration of surgery. However, structural and organisational differences, such as an extended preoperative stays at HVCs and a higher teaching rate, were also apparent. No difference in mortality could be detected.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00068-021-01771-4","type":"journal-article","created":{"date-parts":[[2021,8,16]],"date-time":"2021-08-16T07:04:02Z","timestamp":1629097442000},"page":"2237-2246","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Short-term outcome of isolated lateral malleolar fracture treatment is independent of hospital trauma volume or teaching status: a nationwide retrospective cohort study"],"prefix":"10.1007","volume":"48","author":[{"given":"Malte","family":"Vehling","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claudio","family":"Canal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Franziska","family":"Ziegenhain","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hans-Christoph","family":"Pape","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4012-5628","authenticated-orcid":false,"given":"Valentin","family":"Neuhaus","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,8,16]]},"reference":[{"issue":"1","key":"1771_CR1","doi-asserted-by":"crossref","first-page":"29","DOI":"10.1007\/s001980050113","volume":"9","author":"LJ Melton 3rd","year":"1999","unstructured":"Melton LJ 3rd, Crowson CS, O\u2019Fallon WM.
