The tip of an excessively long ulnar styloid can impinge upon the triangular fibrocartilage complex (TFCC) against the triquetrum. The subtleties in biomechanics of the wrist joint and their role in the production of the symptoms are presented as five cases from a retrospective study. The relationship of the symptoms to the patients' job activities is also discussed. The embryological and anatomical studies show that the tip of the ulnar styloid is covered by the TFCC. Therefore, the term "ulnar styloid impingement syndrome" is adopted for the entity in cases in which the TFCC has remained intact.
尺骨茎突过长可撞击三角纤维软骨复合体 (TFCC) 并抵住三角骨。本文从回顾性研究中选取了五个病例,介绍了腕关节生物力学的细微差别及其在产生症状中的作用。还讨论了症状与患者工作活动的关系。胚胎学和解剖学研究表明,尺骨茎突尖端由 TFCC 覆盖。因此,在 TFCC 保持完整的情况下,采用“尺骨茎突撞击综合征”这一术语来描述该病症。
