Documented falls after lower-extremity-nerve blocks are rare. We believe this paucity of documented falls is the result of underreporting and the lack of serious complications resulting from these falls. In addition, the mechanism(s) for falls after lower-extremity-nerve blocks has not been elucidated.
These reports highlight the mechanism of fall in a patient with a femoral-nerve block (FNB) and in a patient with a femoral-nerve and sciatic-nerve block (FNB/SNB). In addition, we report our findings when volunteers underwent FNB, sciatic-nerve block (SNB) and FNB/SNB and were studied in a gait-analysis laboratory.
Lower-extremity-nerve blocks result in decreased leg stiffness and lateral instability, which may lead to difficulty with pivoting maneuvers.
下肢神经阻滞后有记录的跌倒情况罕见。我们认为，有记录的跌倒情况稀少是报告不足以及这些跌倒未导致严重并发症的结果。此外，下肢神经阻滞后跌倒的机制尚未阐明。
这些报告突出了股神经阻滞（FNB）患者和股神经与坐骨神经联合阻滞（FNB/SNB）患者的跌倒机制。此外，我们报告了志愿者接受FNB、坐骨神经阻滞（SNB）和FNB/SNB并在步态分析实验室接受研究时的发现。
下肢神经阻滞会导致腿部僵硬程度降低和侧向不稳定，这可能会导致转身动作困难。
