[目的]以自行开发的三维CT诊断分析软件为基础，结合Ficat分期，提出股骨头坏死（osteoarthrosis of the femoral head, ONFH）体积分期标准。[方法]根据软件计算所得的坏死评分，参照Ficat分期提出0～6期ONFH体积分期标准，将22例ONFH患者的Ficat分期和体积分期做相关性分析。[结果]本组22例中，按照Ficat分期，Ⅰ期4例，Ⅱa期2例，Ⅱb期3例，Ⅲ期9例，Ⅳ期4例；按照体积分期，1期4例，2期3例，3期2例，4期3例，5期5例，6期5例；体积分期坏死评分与相应的Ficat分期呈明显的线性相关（r=0.976，P<0.01）。[结论]本文所提出的ONFH体积分期准确可行，且较Ficat分期更能客观反应ONFH的整体情况，有助于本病的早期诊断。

Objective]To establish a new volume-depending staging system for ONFH through an analysis software developed by ourselves, referring to Ficat staging system. [Method]With the help of the necrosis score calculated by our software, a new 0~6 volume-depending staging system for ONFH was established referring to Ficat staging system. The correlation analysis was conducted between the Ficat stages and necrosis scores of 22 ONFH cases. [Result]According to Ficat staging system, there were 4 stage Ⅰ, 2 stage Ⅱa, 3 stage Ⅱb, 9 stage Ⅲ, 4 stage Ⅳ. According to the volume-depending staging system, there were 4 cases of stage 1, 3 stage 2, 2 stage 3, 3 stage 4, 5 stage 5, 5 stage 6. A strong linear correlation was observed between the necrosis scores of volume-depending staging system and Ficat staging system(r=0.976,P<0.01). [Conclusion]The new volume-depending staging system might be accurate and feasible. It could indicate the whole condition of ONFH more objective than Ficat staging system, which would be helpful for early diagnosis of ONFH.
