However, various bioabsorbable osteosynthesis materials have been in use for a number of years. One recent innovation is the Shark Screw\u00ae, a human cortical bone allograft. This study aimed to evaluate the efficacy and safety of this allogeneic screw in the stabilization of Reversed L-Shaped osteotomy, a modified Chevron osteotomy. Methods: In a prospective study, 15 patients underwent a Reversed L-Shaped osteotomy stabilized with the allogenic bone screw Radiological data on osteointegration of the screw and correction of the intermetatarsal angle were recorded. Furthermore, each follow-up examination included the collection of clinical data, the American Orthopedic Foot and Ankle Society (AOFAS) score, evaluation of pain level, and patient\u2019s overall satisfaction. Results: Full osseous fusion of the osteotomy was seen in all patients. The bone screws were radiographically integrated after approximately 6.5 (\u00b12.6) months. Neither nonunion nor failure occurred in any of our cases. Furthermore, we did not find any potential graft reaction. The AOFAS score improved significantly from 51.6 (\u00b115.2) points to 90.9 (\u00b110.3) (p &lt; 0.001). The preoperative hallux valgus angle and intermetatarsal angle decreased significantly from 24.8 (\u00b14.9) degrees to 7.2 (\u00b14.4) degrees (p &lt; 0.001) and 12.6 (\u00b13.2) degrees to 4.8 (\u00b11.3) degrees (p &lt; 0.001), respectively. Conclusions: With this study, we demonstrated the efficiency of the allogenic bone screw (Shark Screw\u00ae) in regard to clinical and radiological short-term outcomes.<\/jats:p>","DOI":"10.3390\/jcm11051384","type":"journal-article","created":{"date-parts":[[2022,3,3]],"date-time":"2022-03-03T09:24:53Z","timestamp":1646299493000},"page":"1384","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["The Application of an Allogenic Bone Screw for Stabilization of a Modified Chevron Osteotomy: A Prospective Analysis"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5294-4191","authenticated-orcid":false,"given":"Thorsten","family":"Huber","sequence":"first","affiliation":[{"name":"Department of Orthopedics and Trauma Surgery, Klinikum Wels-Grieskirchen, 4600 Wels, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan G.","family":"Hofst\u00e4tter","sequence":"additional","affiliation":[{"name":"Independent Researcher, 4600 Wels, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rainer","family":"Fiala","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Klinik Donaustadt, 1220 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0217-850X","authenticated-orcid":false,"given":"Florian","family":"Hartenbach","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Trauma Surgery, Klinikum Wels-Grieskirchen, 4600 Wels, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Breuer","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Trauma Surgery, Klinikum Wels-Grieskirchen, 4600 Wels, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bj\u00f6rn","family":"Rath","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Trauma Surgery, Klinikum Wels-Grieskirchen, 4600 Wels, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"25","DOI":"10.1097\/00003086-198106000-00007","article-title":"A new osteotomy for hallux valgus: A horizontally directed \u201cV\u201d displacement osteotomy of the metatarsal head for hallux valgus and primus varus","volume":"157","author":"Austin","year":"1981","journal-title":"Clin.
