Abstract:
Osteonecrosis of the femoral head (ONFH) is a common and refractory disease in the clinic. Although the exact pathophysiological mechanism is not fully understood, it is believed to be closely related to the interruption of intra-bone circulation and eventual bone tissue death. The prevention and treatment of ONFH is always a great challenge for orthopedists. The diagnostic level of ONFH has been continuously improved with the development of imaging techniques such as MRI and the in-depth understanding of the disease in recent years.There are many treatment methods for ONFH, which are generally considered individually and comprehensively according to factors such as the patient\'s age, osteonecrosis stage, classification, and compliance with joint-sparing treatment. There is currently no unified standard. ONFH staging and classification play an important reference value for doctors to choose treatment options. In recent years, based on the characteristics of ONFH in Chinese people, the academic community has proposed Chinese staging and China-Japan Friendship Hospital (CJFH) classification. The consensus also introduces them together with the international Association Research Circulation Osseous (ARCO) staging to provide guidance for individualized treatment of ONFH. In order to further standardize the diagnosis of ONFH and expand the treatment of ONFH, the Association Related to Circulation Osseous, Chinese Microcirculation Society (CSM-ARCO) organized domestic experts in the field of ONFH to jointly formulate the expert consensus, in order to provide reference for the standardized diagnosis of ONFH and the selection of individualized diagnosis and treatment techniques.
股骨头坏死(osteonecrosis of the femoral head,ONFH)是临床常见难治性疾病。该病确切病理生理机制尚不完全清楚,普遍认为与骨内循环中断和最终骨组织死亡紧密相关。ONFH的预防和治疗一直是临床骨科医生面临的巨大挑战。其诊断水平随着MRI等影像技术的发展和近年来对疾病的深入认识而不断提高。目前临床治疗方法众多,一般根据患者年龄,骨坏死分期、分型,以及对保留关节治疗的依从性等因素个体化综合考虑,目前尚未达成统一的专家意见。其中,ONFH分期、分型对术者选择治疗方案具有重要参考价值,近年来结合国人ONFH发病特点,学界提出了中国分期、中日友好医院(CJFH)分型,此共识也将其与国际骨循环研究协会(ARCO)分期共同引入,为ONFH个体化治疗提供指导。中国微循环学会骨微循环专业委员会组织国内ONFH领域的专家,共同制定《股骨头坏死临床诊疗技术专家共识(2022年)》,以期为ONFH的规范诊断和个体化治疗技术选择提供一定参考意见。.
