Abstract

Introduction Pain on the ulnar side of the wrist is a complex diagnostic dilemma and the triangular fibrocartilage complex provides much needed support to the wrist, and extensor carpi ulnaris (ECU) tendon is part of the complex. The most important investigations to diagnose wrist pathologies include ultrasound, computed tomography, and MRI. Aim The aim of this study is to evaluate the diagnostic performance of both ultrasonography and MRI findings in ECU tendon part of triangular fibrocartilage complex. Patients and methods This control study was carried out on 50 patients with ulnar side wrist pain. The study was conducted in the period from May 2018 to May 2020 at the Radiology Department and approved by the Ethics Committee, and all patients gave their informed consent before inclusion in the study. Results were collected then analyzed using a specialized computer statistical program. Results MRI detected ECU injury in 13 joints, whereas ultrasound detected it in 17 joints. They both agreed in 46 joints. MRI missed four joints with ECU injury detected by ultrasound. Statistical analysis of the results showed a highly significant agreement (P value) between both MRI and ultrasound in the detection of ECU injury. Conclusion Both MRI and musculoskeletal ultrasound have complimentary roles in the evaluation of different causes of ulnar sided wrist pain. Musculoskeletal ultrasound is highly recommended for the examination of tendons and inflammatory changes of the wrist.

高分辨率超声与MRI评价三角纤维软骨复合体
腕尺侧疼痛是一个复杂的诊断难题,三角形纤维软骨复合体为腕提供了急需的支持,尺侧腕伸肌(ECU)肌腱是复合体的一部分。诊断手腕病变最重要的检查包括超声、计算机断层扫描和MRI。目的探讨三角形纤维软骨复合体ECU肌腱部分的超声和MRI诊断价值。患者与方法对50例尺侧腕关节疼痛患者进行对照研究。该研究于2018年5月至2020年5月在放射科进行,经伦理委员会批准,所有患者在纳入研究前均给予知情同意。收集结果,然后使用专门的计算机统计程序进行分析。结果MRI检出ECU损伤13例,超声检出ECU损伤17例。他们在46个关节上都达成了一致。MRI遗漏4个关节,超声检查ECU损伤。统计分析结果显示,MRI与超声对ECU损伤的检测具有高度显著的一致性(P值)。结论MRI与骨骼肌超声对尺侧腕关节不同病因的诊断具有互补作用。肌肉骨骼超声被强烈推荐用于检查肌腱和手腕的炎症变化。
