Ludloff had an impact in the diagnostics, physical examination, orthopedic imaging, and orthopedic surgical technique of his era. He was a pioneer in the surgical treatment of dysplastic hip, anterior cruciate ligament reconstruction, and hallux valgus. His surgical technique for the correction of hallux valgus, initially stabilized with plaster of Paris, remained unpopular among other orthopedic surgeons for decades. In the 1990s, the advent and use of improved orthopedic materials for fixation attracted the interest of numerous orthopedic surgeons in the Ludloff osteotomy for its ability to correct the deformity in all 3 dimensions, its anatomic outcomes, and its low recurrence rate and patient satisfaction.<\/jats:p>","DOI":"10.1177\/1553350618775506","type":"journal-article","created":{"date-parts":[[2018,5,21]],"date-time":"2018-05-21T02:03:25Z","timestamp":1526868205000},"page":"417-420","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Karl Ludloff (1864-1945): An Inventive Orthopedic Surgeon, His Work and His Surgical Technique for the Correction of Hallux Valgus"],"prefix":"10.1177","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5753-1927","authenticated-orcid":false,"given":"Konstantinos","family":"Markatos","sequence":"first","affiliation":[{"name":"Biomedical Research Foundation of the Academy of Athens, Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Georgios","family":"Karaoglanis","sequence":"additional","affiliation":[{"name":"Henry Dunant Hospital Center, Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5454-2564","authenticated-orcid":false,"given":"Christos","family":"Damaskos","sequence":"additional","affiliation":[{"name":"Laiko General Hospital of Athens, Athens, Greece"},{"name":"National and Kapodistrian University of Athens, Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9980-0056","authenticated-orcid":false,"given":"Nikolaos","family":"Garmpis","sequence":"additional","affiliation":[{"name":"Laiko General Hospital of Athens, Athens, Greece"},{"name":"National and Kapodistrian University of Athens, Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gerasimos","family":"Tsourouflis","sequence":"additional","affiliation":[{"name":"Laiko General Hospital of Athens, Athens, Greece"},{"name":"National and Kapodistrian University of Athens, Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4746-0843","authenticated-orcid":false,"given":"Konstantinos","family":"Laios","sequence":"additional","affiliation":[{"name":"Biomedical Research Foundation of the Academy of Athens, Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gregory","family":"Tsoucalas","sequence":"additional","affiliation":[{"name":"Democritus University of Thrace, Komotini, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2018,5,20]]},"reference":[{"key":"bibr1-1553350618775506","unstructured":"Whonamedit?
