The clinical application of MRI technology in the injury of triangular fibrocartilage complex

Objective To explore the clinical application of MRI technology in the injury of triangular fibrocartilage complex and its ligament. Clear its value in clinical treatment.Methods Review 5 normal volunteer and 21 cases patien whom pain in wrist. Evaluate the sequence of GRE T2、SE T1、STIR and 3D dynamic scan in the wrist. Results MRI play the important role to evaluate the TFCC、scapholunate ligament (SLL), and lunotriquetral ligament(LTL).In 21 cases pain of wrist patien, there were 8 cases suffer TFCC tears. SLL injure in 4 cases and TLT injure in 2 cases. The fracture in the wrist bone are 5 case. Rheumatoid arthritis are 4 case, Ischemia necrosis 2case. Conclusion The wrist injure often with TFCC and ligament lesion, it worth pay attention to clinic. The structure of wrist is complex, for accurate dialogic,we must use multi sequence and many orientation to show the anatomic. Key words: Wrist; Friangular fibrocartilage; MRI
