Injuries to the lumbosacral plexus during labor and delivery have been reported in the literature for years, but have lacked electrophysiologic testing to substantiate the location of the nerve injury. We report 2 cases with comprehensive electrophysiologic testing which localizes the site of this obstetrical paralysis to the lumbosacral trunk (L4-5) and S-1 root where they join and pass over the pelvic rim. The paralysis may be mild or severe. Small maternal size, a large fetus, midforceps rotation, and fetal malposition may place the mother at risk for this nerve injury.
多年来，文献中已有关于分娩期间腰骶丛损伤的报道，但一直缺乏电生理测试来证实神经损伤的部位。我们报告2例进行了全面电生理测试的病例，测试将这种产科麻痹的部位定位在腰骶干（L4 - 5）和S - 1神经根汇合并越过骨盆边缘的位置。这种麻痹可能轻微，也可能严重。产妇身材矮小、胎儿过大、产钳中位旋转和胎位异常可能使母亲面临这种神经损伤的风险。
