The aim of our study was to compare the findings of high-resolution sonography of the triangular fibrocartilage with those of MRI and arthroscopy. SUBJECTS AND METHODS. Thirteen patients with clinically suspected triangular fibrocartilage tears prospectively underwent sonography, followed by MRI, of their wrists. Triangular fibrocartilage tears were classified as predominantly ulnar or predominantly radial. Only the surgeon was aware of the results of both studies, and eight patients subsequently underwent arthroscopy. The findings of the different techniques were compared.
For the presence or absence of a tear, seven (87.5%) of eight sonographic examinations correlated with arthroscopy, and 11 (84.6%) of 13 sonographic examinations correlated with MRI. Sonography missed one small radial tear that was detected at arthroscopy and MRI, but sonography showed an ulnar tear in triangular fibrocartilage that appeared normal on MRI.
High-resolution sonography shows good correlation with MRI and arthroscopy for the evaluation of triangular fibrocartilage tears. Sonography has the potential to be a rapid and cost-effective means of diagnosing tears of the triangular fibrocartilage, particularly those involving the ulnar aspect of the cartilage.
我们研究的目的是比较三角纤维软骨的高分辨率超声检查结果与MRI和关节镜检查结果。
13例临床怀疑三角纤维软骨撕裂的患者前瞻性地接受了手腕部的超声检查，随后进行了MRI检查。三角纤维软骨撕裂分为主要尺侧撕裂或主要桡侧撕裂。只有外科医生知道两项检查的结果，8例患者随后接受了关节镜检查。比较了不同技术的检查结果。
对于是否存在撕裂，8例超声检查中有7例（87.5%）与关节镜检查结果相符，13例超声检查中有11例（84.6%）与MRI检查结果相符。超声检查漏诊了1例在关节镜检查和MRI检查中发现的小的桡侧撕裂，但超声检查显示三角纤维软骨有尺侧撕裂，而MRI显示正常。
高分辨率超声检查在评估三角纤维软骨撕裂方面与MRI和关节镜检查有良好的相关性。超声检查有可能成为诊断三角纤维软骨撕裂的一种快速且经济有效的方法，尤其是那些累及软骨尺侧的撕裂。
