Trigger digit is a common condition which is largely idiopathic in etiology. Less frequently, it has been described secondary to anatomical variations or space occupying lesions. We describe a patient who developed a recurrent trigger finger after a surgical release of the first annular pulley. Intraoperatively, the trigger was noted to be caused by herniation of the flexor digitorum profundus (FDP) tendon into a noose formed by the two slips of the flexor digitorum superficialis tendon (FDS) and the proximal edge of the second annular pulley. Level V (Therapeutic).
扳机指是一种常见的病症，其病因在很大程度上是特发性的。不那么常见的是，它继发于解剖变异或占位性病变。我们描述了一位患者，其在接受第一环状滑车切开松解术后出现复发性扳机指。术中发现，扳机指是由深屈肌腱（FDP）肌腱疝入由浅屈肌腱（FDS）的两个肌腱和第二环状滑车近端边缘形成的套索引起的。5 级（治疗性）。
