Extensor tendon subluxation or dislocation resulting from sagittal band rupture can be associated with snapping, catching, locking, pain, and swelling of the finger. Several etiologies were reported in the literature, with frequent mention of a traumatic rupture caused by a direct blow at the level of the metacarpophalangeal joint (MCPJ). The other causes of sagittal band injuries are degenerative disease, congenital infection, and rheumatoid arthritis. To our knowledge, we report the first case of spontaneous idiopathic bilateral sagittal band rupture.
We, herein, present the case of a seronegative 29-year-old female who presented with pain and swelling in the dominant hand for 4 days.
Upon examination, she was found to have bilateral dislocation of the extensor tendons at the level of the (MCPJ) of the third and fourth digits. Any underlying cause was excluded, and the diagnosis was confirmed with a dynamic ultrasound study.
矢状带破裂导致的伸肌腱半脱位或脱位可能与手指的弹响、卡顿、绞锁、疼痛和肿胀有关。文献报道了多种病因，经常提到的是掌指关节（MCPJ）水平受到直接打击导致的创伤性破裂。矢状带损伤的其他原因包括退行性疾病、先天性感染和类风湿性关节炎。据我们所知，我们报告了首例自发性特发性双侧矢状带破裂病例。
在此，我们介绍一名29岁血清阴性女性的病例，她主手疼痛和肿胀4天。
经检查，发现她第三和第四指掌指关节（MCPJ）水平的伸肌腱双侧脱位。排除了任何潜在病因，并通过动态超声检查确诊。
