Recently, bone grafts have been introduced in orthopedic procedures, namely osteosynthesis and arthrodesis. Allografts can induce bone formation, provide support for vascular and bone ingrowth and have a low risk of immunological rejection. A 52-year-old female patient with hallux rigidus underwent arthrodesis of the first metatarsophalangeal joint using Shark Screw\u00ae made of allogenic cortical bone. Corrective surgery was performed after 10 weeks, and a 5 \u00d7 3 mm large part of the Shark Screw\u00ae with the surrounding patient\u2019s bone was removed. A histological evaluation revealed a vascularized graft with the newly formed compact lamellar bone fitting exactly to the cortical graft. The bone surface was lined by plump osteoblasts with osteoid production, and osteocytes were present in the lacunae. The arthrodesis of the first metatarsophalangeal joint using an allogenic cortical bone graft results in fast, primary bone healing without immunological rejection. This case suggests that the cortical allograft is a good and safe treatment option with an excellent graft incorporation into the host bone. However, as the literature evaluating the histology of different bone grafts is scarce, further high-level evidence studies with adequate sample sizes are needed to confirm our findings.<\/jats:p>","DOI":"10.3390\/life11060473","type":"journal-article","created":{"date-parts":[[2021,5,24]],"date-time":"2021-05-24T12:38:01Z","timestamp":1621859881000},"page":"473","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Incorporation of an Allogenic Cortical Bone Graft Following Arthrodesis of the First Metatarsophalangeal Joint in a Patient with Hallux Rigidus"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9847-0171","authenticated-orcid":false,"given":"Iva","family":"Brcic","sequence":"first","affiliation":[{"name":"Diagnostic and Research Institute of Pathology, Medical University of Graz, 8010 Graz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Klaus","family":"Pastl","sequence":"additional","affiliation":[{"name":"Department for Orthopedic Surgery, Diakonissen Hospital Linz, 4020 Linz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1112-0908","authenticated-orcid":false,"given":"Harald","family":"Plank","sequence":"additional","affiliation":[{"name":"Graz Centre of Electron Microscopy, 8010 Graz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0247-8393","authenticated-orcid":false,"given":"Jasminka","family":"Igrec","sequence":"additional","affiliation":[{"name":"Division of General Radiology, Department of Radiology, Medical University of Graz, 8036 Graz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jakob E.","family":"Schanda","sequence":"additional","affiliation":[{"name":"Department for Trauma Surgery, AUVA Trauma Center Vienna-Meidling, 1120 Vienna, Austria"},{"name":"Ludwig Boltzmann Institute for Experimental and Clinical Traumatology, 1200 Vienna, Austria"},{"name":"Austrian Cluster for Tissue Regeneration, 1200 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eva","family":"Pastl","sequence":"additional","affiliation":[{"name":"Department for Orthopedic Surgery, Diakonissen Hospital Linz, 4020 Linz, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mathias","family":"Werner","sequence":"additional","affiliation":[{"name":"FB Pathology, Osteopathology, VIVANTES Netzwerk f\u00fcr Gesundheit, 13407 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.fcl.2010.12.003","article-title":"First metatarsophalangeal arthrodesis for hallux rigidus","volume":"16","author":"Fuhrmann","year":"2011","journal-title":"Foot Ankle Clin."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"341","DOI":"10.1016\/j.cpm.2012.04.002","article-title":"End-stage hallux rigidus: Cheilectomy, implant, or arthrodesis?","volume":"29","author":"Peace","year":"2012","journal-title":"Clin.
