The Journal will provide free and open access to scholarly work, education and discussion to meet the needs of practitioners, health workers, researchers, scientists and policy makers. The journal will be managed by the Biologic Orthopedics Journal Association, which will be responsible for administering the process of article submissions, review, and publication along with the supporting complements, a website and digital platform to empower readers of the journal and connect them to critical resources.</span></p> <p style="margin: 0px; line-height: 115%;"><span style="margin: 0px; line-height: 115%; font-family: 'Garamond',serif; font-size: 14pt;">&nbsp;</span></p> <p style="margin: 0px; line-height: 115%;"><span style="margin: 0px; line-height: 115%; font-family: 'Garamond',serif; font-size: 14pt;">The Journal articulates and disseminates new science and clinical research for advancing the scholarship and practice of regenerative medicine in the field of orthopedics and to provide evidence-based best practices.<span style="margin: 0px;">&nbsp; </span>The journal also increases world-wide exposure to the innovations, experiences and perspectives of practitioners working in the field. Article submissions are encouraged from throughout the world, and be subject to peer review. As such, this journal serves as a reputable and authoritative resource to help influence clinical practice, research funding, policy, and operational decisions regarding biologics in orthopedics.&nbsp;</span></p> Biologic Orthopedics Journal Association en-US Biologic Orthopedics Journal 2766-9777 Etiology and Pathogenesis of Corticosteroid-Associated Osteonecrosis of the Femoral Head https://biologicortho.com/index.php/BiologicOrtho/article/view/18 <p>Osteonecrosis of the femoral head (ONFH) is an intractable disease occurring at a relatively young age. The characteristic finding of ONFH – the femoral head collapse with severe hip pain – is observed in many cases, which frequently leads to further joint destruction, requiring surgical treatment. Among the associated factors of ONFH, majority of patients who require high-dose corticosteroid are still challenging due to inevitable therapeutic option regardless of poor prognosis. As a pathological mechanism, ONFH is defined as tissue necrosis in the femoral head region due to occlusion of the nutrient vessels; but the detailed micro-level processes leading to blood flow failure remains unclear. The elucidation of ONFH and the establishment of preventive therapy is desirable for these patients. Here, we discuss the etiology and pathogenesis of corticosteroid-associated ONFH by reviewing current literature.</p> Yusuke Kubo Wolf Drescher Thomas Pufe Copyright (c) 2021 Biologic Orthopedics Journal 2021-08-26 2021-08-26 3 SP1 e1 e8 10.22374/boj.v3iSP1.18
