MRI对腕三角纤维复合体损伤的诊断研究进展

Research Progress of MRI in Diagnosis of TFCC Injury

摘要: 三角纤维软骨复合体(Triangular FibroCartilage Complex，简称TFCC)是腕关节尺侧最重要的纤维软骨–韧带复合结构，位于腕关节尺侧，分隔尺腕和远侧尺桡关节，具有稳定下尺桡关节、尺腕关节，缓冲压力的作用，当TFCC发生炎症、创伤及退行性变的情况下，会导致腕尺侧疼痛、下尺桡关节不稳、腕部功能障碍。随着影像学技术的发展，磁共振成像(MRI)已成为目前无创性诊断TFCC损伤的最佳方法。MRI是一种无创性的影像学检查方法，软组织分辨率高，能对TFCC的精细解剖结构进行较好的评价，能较好地显示损伤的部位及范围，有利于临床治疗方案的制定，现就TFCC的MRI最新研究现状予以综述。

Abstract: Triangular FibroCartilage Complex (TFCC) is the most important fibrocartilage-ligament composite structure on the ulnar side of the wrist joint. It is located on the ulnar side of the wrist joint, sepa-rates the ulnocarpal and distal radioulnar joints, and has the function of stabilizing the lower ra-dioulnar joint. Joints and ulnocarpal joints play a role in buffering pressure. When inflammation, trauma and degeneration occur in the TFCC, it will lead to pain on the ulnar side of the wrist, insta-bility of the distal radioulnar joint, and poor wrist function. With the advancement of imaging tech-nology, magnetic resonance imaging (MRI) has become the current non-invasive method for diag-nosing TFCC injuries. MRI is a non-invasive imaging examination with high soft tissue resolution. It can evaluate the fine anatomical structure of TFCC and accurately display the location and scope of damage, which is beneficial to the formulation of clinical treatment plans. Here is the latest MRI of TFCC. The current research status is reviewed.
