Abstract:
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.
