Abstract: ［Abstract］ Objective Mycobacterium fortuitum belongs to the rapidly growing mycobacteria， which is widely distributed in nature， but the clinical cases of mycobacterium fortuitum infectionin in orthopedics rarely reported. Now， we shared a clinical case of our hospital to provide reference for clinical treatment. Methods The process of laboratory examination， clinical features and treatment were analyzed retrospectively. Results Non?tuberculous mycobacterium infection can be easily misdiagnosed with mycobacterium tuberculosis infection， or missed during diagnose. The conventional bacterial culture is difficult to find the infection caused by Mycobacterium fortuitum， and its treatment has a loug-term process. Conclusion More and more non?tuberculosis mycobacterium infection are reported， the isolation， culture and identification of non?tuberculous Mycobacteria are of great significance to clinical practice.
