Twenty-five patients presenting consecutively with persistent pain and tenderness, edema, and vasomotor instability in an extremity following trauma to the same extremity were clinically diagnosed as having early post-traumatic reflex dystrophy (PRD). All underwent scintigraphy with 99mTechnetium methylene diphosphonate before institution of prednisolone treatment. The time lag between the occurrence of the initial trauma and scintigraphic imaging averaged 11.5 weeks. Of 25 scintigrams, 24 showed multiple periarticular accentuation in the affected extremity. Scintigraphy is a useful clinical aid to establish the diagnosis of early PRD.
25例同一肢体创伤后出现该肢体持续性疼痛、压痛、水肿及血管舒缩功能不稳定的患者，经临床诊断为早期创伤后反射性交感神经营养不良（PRD）。所有患者在使用泼尼松龙治疗前均接受了99m锝亚甲基二膦酸盐闪烁扫描。初始创伤发生与闪烁扫描成像之间的时间间隔平均为11.5周。25份闪烁扫描图中，24份显示患侧肢体多个关节周围放射性增强。闪烁扫描是早期PRD诊断的一种有用的临床辅助手段。
