A systematic literature review was performed per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines through a comprehensive English literature search on January 2023 through four databases (Embase, PubMed, Cochrane Library, and Scopus), including studies reporting on FHAVN post-COVID-19. Fourteen articles were included, ten (71.4%) were case reports, and four (28.6%) case series reported on 104 patients having a mean age of 42.2\u2009\u00b1\u200911.7 (14:74) years, in which 182 hip joints were affected. In 13 reports, corticosteroids were used during the COVID-19 management plan for a mean of 24.8\u2009\u00b1\u200911 (7:42) days, with a mean prednisolone equivalent dose of 1238.5\u2009\u00b1\u2009492.8 (100:3520) mg. A mean of 142.1\u2009\u00b1\u2009107.6 (7:459) days passed between COVID-19 diagnosis and FHAVN detection, and most of the hips were stage II (70.1%), and concomitant septic arthritis was present in eight (4.4%) hips. Most hips (147, 80.8%) were treated non-surgically, of which 143 (78.6%) hips received medical treatment, while 35 (19.2%) hips were surgically managed, 16 (8.8%) core decompression, 13 (7.1%) primary THA, five (2.7%) staged THA and three (1.6%) had first stage THA (debridement and application of antibiotic-loaded cement spacer). The outcomes were acceptable as regards hip function and pain relief. Femoral head avascular necrosis post-COVID-19 infection is a real concern, primarily attributed to corticosteroid usage, besides other factors. Early suspicion and detection are mandatory, as conservative management lines are effective during early stages with acceptable outcomes. However, surgical intervention was required for progressive collapse or patients presented in the late stage.<\/jats:p>","DOI":"10.1007\/s00296-023-05373-8","type":"journal-article","created":{"date-parts":[[2023,6,20]],"date-time":"2023-06-20T08:02:31Z","timestamp":1687248151000},"page":"1583-1595","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["Femoral head avascular necrosis in COVID-19 survivors: a systematic review"],"prefix":"10.1007","volume":"43","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6764-4148","authenticated-orcid":false,"given":"Ahmed Abdelazim A.","family":"Hassan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0710-6487","authenticated-orcid":false,"given":"Ahmed A.","family":"Khalifa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,6,20]]},"reference":[{"issue":"1","key":"5373_CR1","doi-asserted-by":"publisher","first-page":"157","DOI":"10.23750\/abm.v91i1.9397","volume":"91","author":"D Cucinotta","year":"2020","unstructured":"Cucinotta D, Vanelli M (2020) WHO Declares COVID-19 a Pandemic.
