Absence of flexor digitorum superficialis function in the little finger is a relatively common congenital anomaly that can complicate assessment of little finger injuries. We reviewed the prevalence of unilateral and bilateral absence of superficialis function in the published literature. In appropriate studies identified (1352 people), the anomaly was unilateral in 92 individuals (6.8%) and bilateral in 81 (6.0%). If superficialis function is absent in one little finger, the probability of absence in the opposite hand is 0.64. If superficialis function is present, the probability of absence in the other little finger is 0.02 (1 in 50). Absence of little finger superficialis function in one hand is therefore not a reliable indicator of this function in the opposite hand.
小指指浅屈肌功能缺如是一种相对常见的先天性异常，会使小指损伤的评估变得复杂。我们回顾了已发表文献中单侧和双侧指浅屈肌功能缺失的发生率。在纳入的合适研究（1352人）中，该异常为单侧的有92人（6.8%），双侧的有81人（6.0%）。如果一侧小指指浅屈肌功能缺失，另一侧手出现该功能缺失的概率为0.64。如果一侧小指指浅屈肌功能存在，另一侧小指出现功能缺失的概率为0.02（1/50）。因此，一只手小指指浅屈肌功能缺失并不能可靠地提示另一只手的该功能情况。
