We conducted a systematic review and meta-analysis of recent research on the risk of AVN following the stabilization of fractured femoral neck with implants in PubMed. We assessed the effect of age on AVN incidence among patients aged &gt; 50 and younger, depending on fracture type, Garden stage, Pouwels degree, Delbet stage, and age category. We followed PRISMA guidelines. Relevant studies were defined as research articles describing real-world studies reporting on the risk of AVN following primary surgical fracture stabilization with implants, published between 1 January 2011 and 22 April 2021. Fifty-two papers met the inclusion criteria, with a total of N = 5930 with surgically managed fractures. The pooled mean AVN incidence was significantly higher among patients with displaced fractures (20.7%; 95% CI: 12.8\u201328.5%) vs. those with undisplaced fractures (4.7%; 95% CI: 3.4\u20136.0%). No significant correlation was observed between AVN incidence weighted by sample size and time interval from injury to surgery (p = 0.843, R2 = 0.01). In conclusion, the risk of AVN following femoral neck fractures was generally high, especially in patients with displaced fractures. The time from injury to surgery did not correlate with AVN incidence.<\/jats:p>","DOI":"10.3390\/ijerph191610050","type":"journal-article","created":{"date-parts":[[2022,8,15]],"date-time":"2022-08-15T20:58:08Z","timestamp":1660597088000},"page":"10050","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":38,"title":["The Risk of Avascular Necrosis Following the Stabilization of Femoral Neck Fractures: A Systematic Review and Meta-Analysis"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5542-9988","authenticated-orcid":false,"given":"Wojciech","family":"Konarski","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Ciechan\u00f3w Hospital, 06-400 Ciechan\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1376-2966","authenticated-orcid":false,"given":"Tomasz","family":"Pobo\u017cy","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Ciechan\u00f3w Hospital, 06-400 Ciechan\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrzej","family":"Kotela","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Collegium Medicum, Cardinal Stefan Wyszynski University in Warsaw, Woycickiego 1\/3, 01-938 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0239-1637","authenticated-orcid":false,"given":"Andrzej","family":"\u015aliwczy\u0144ski","sequence":"additional","affiliation":[{"name":"Social Medicine Institute, Department of Social and Preventive Medicine, Medical University of Lodz, 90-419 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ireneusz","family":"Kotela","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery and Traumatology, Central Research Hospital of Ministry of Interior, Wo\u0142oska 137, 02-507 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4993-2039","authenticated-orcid":false,"given":"Martyna","family":"Hordowicz","sequence":"additional","affiliation":[{"name":"General Psychiatry Unit III, Dr Barbara Borzym\u2019s Independent Public Regional Psychiatric Health Care Center, 26-600 Radom, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3435-9658","authenticated-orcid":false,"given":"Jan","family":"Krakowiak","sequence":"additional","affiliation":[{"name":"Social Medicine Institute, Department of Social and Preventive Medicine, Medical University of Lodz, 90-419 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,15]]},"reference":[{"key":"ref_1","unstructured":"Barney, J., Piuzzi, N.S., and Akhondi, H.
