Abstract:
Locked metacarpophalangeal joint is an uncommon phenomenon with many possible etiologies. Diagnosis can be difficult because of the many more common pathologies (trigger finger, sagittal band lesion, etc.) that can lead to a clinical picture that may resemble the locked metacarpophalangeal joint. Once the differential diagnoses have been eliminated, the etiology of this blockage must be determined and the surgical procedure must be oriented. The origin of the problem is often difficult to determine, especially since standard imaging tests are often not very informative. Several clinical forms are possible, with blockages in extension or flexion, but which will have a disabling functional impact on the overall function of the hand. Currently, there is no gold standard for the management of this condition. In this study, we performed a review of the literature in order to better understand the different possible etiologies but also to analyze the different diagnostic and therapeutic management.

摘要:
掌指关节锁定是一种罕见的现象,有许多可能的病因。由于许多更常见的病理(触发手指,矢状带病变,等。),可能导致类似于锁定的掌指关节的临床表现。一旦鉴别诊断被消除,必须确定这种阻塞的病因,并且必须确定外科手术的方向。问题的根源往往难以确定,特别是标准的影像学检查通常信息不多。几种临床形式是可能的,伸展或屈曲阻塞,但这将对手的整体功能产生功能影响。目前,这种情况的管理没有黄金标准。在这项研究中,我们回顾了文献,以便更好地了解不同的可能病因,同时分析不同的诊断和治疗管理.证据级别:IV.
