摘要

為了評估高解析度超音波檢查於腕三角韌帶之應用，我們針對35位病人共完成53個腕部高解析度超音波檢查，每例均經腕關節攝影檢查證實為正常之腕三角韌帶。超音波檢查發現所有腕三角韌帶均位於橈尺關節之遠末端於橫切及斜矢狀切面下呈現均勻高回音之倒三角形結構，於斜矢狀切面下其大小從2.3mm至4.2mm，而於橫切面下則為2.4mm至3.smm。亦即正常之腕三角韌帶應大於2.5mm。所以我們認為高解析度超音波檢查可以準確且可靠地評估腕三角韌帶。進一步應可利用於腕三角韌帶疾病之診斷。

The purpose of the study was to describe the appearance of the triangular fibrocartilage (TFC) on high resolution ultrasound (HRUS). HRUS was performed on the wrist joint in 53 wrists of 35 patients (age range: 18-72 years, mean: 36.8 years). Chronic pain was detected in 35 wrists and 18 were asymptomatic. Multicompartment injection wrist arthrography indicated normal TFCs in all the wrists. TFC of the wrist appeared as an inverse triangular structure with homogeneous hyperechogenicity in transverse and oblique sagittal scan at the level of the distal radio-ulnar joint. The measurements range from 2.3 mm to 4.2 mm (mean value 3±0.39 mm) in the oblique sagittal scan and from 2.4 mm to 3.8 mm (mean value 3.09±0.33 mm) in transverse scan. An analysis of the patients' age, sex and left or right hand yielded no statistical significance. In normal conditions, the TFC is thicker than 2.5 mm in transverse and oblique sagittal section with a confidence level of 95%. The TFC can be accurately and reliably displayed on HRUS as a homogeneous hyperechoic inverted triangular structure in normal subjects.
