This study was designed to assess the clinical significance of arthrographic abnormalities in the ligaments of a painful wrist. This was accomplished by means of comparison arthrography of the asymptomatic wrist. Fifty-six consecutive patients with unilateral wrist pain underwent selective bilateral arthrography to assess interruptions of continuity of the triangular fibrocartilage, lunotriquetral, and scapholunate ligaments. The prevalence of bilaterally symmetric lesions was high. In patients with ligament defects in the symptomatic wrist, 88% of defects near the radial attachment of the triangular fibrocartilage, 59% of lunotriquetral defects, and 57% of scapholunate defects were bilateral. Furthermore, physical examination was not predictive of specific ligament defects. This study raises questions concerning the relevance of interrupted ligaments in the diagnosis of wrist pain.
本研究旨在评估疼痛性腕关节韧带造影异常的临床意义。这是通过对无症状腕关节进行对比造影来实现的。连续56例单侧腕关节疼痛患者接受了选择性双侧造影，以评估三角纤维软骨、月三角韧带和舟月韧带的连续性中断情况。双侧对称病变的发生率很高。在有症状腕关节存在韧带缺损的患者中，三角纤维软骨桡侧附着处附近缺损的88%、月三角韧带缺损的59%以及舟月韧带缺损的57%为双侧性。此外，体格检查无法预测特定的韧带缺损。本研究对韧带中断在腕关节疼痛诊断中的相关性提出了疑问。
