Variations in the course of the lumbar plexus and lumbosacral trunk have been explored with respect to variant nerve roots being indicated in atypical sciatic pain. Typically, the furcal nerve emerges from the L4 nerve root, with a single contribution. However, we report a case where the furcal nerve was found to arise not only from the L4 nerve but also from the obturator nerve. This anatomical variation is explored in terms of its clinical significance and implications in lumbar and sacral plexus associated procedures.
腰椎丛和腰骶干的走行变异已被探讨，因为在非典型坐骨神经痛中，神经根的变异已经被指出。通常情况下，分叉神经从 L4 神经根发出，仅有单一的贡献。然而，我们报告了一个病例，其中发现分叉神经不仅起源于 L4 神经根，还起源于闭孔神经。这种解剖学变异从其在腰椎和骶丛相关手术中的临床意义和影响方面进行了探讨。
