Foot drop is a common and debilitating finding in patients with lumbar spinal disorders. Recovery of function after surgical treatment of the underlying disorder is not well documented in the literature. The purpose of this retrospective study was to analyze the prognosis of preoperative foot drop after lumbar surgery in 55 patients with foot drop and herniated nucleus pulposus and/or lumbar spinal stenosis. Preoperative dorsiflexion motor strength improved measurably in 98%, and 71% had full recovery of strength. All patients had associated neurologic findings and 71% experienced complete resolution. No statistically significant relationship was found between the extent of recovery and age, diagnosis (herniated nucleus pulposus lumbar spinal stenosis), duration of symptoms, or severity of preoperative weakness. In our series, the prognosis of preoperative foot drop and associated neurologic deficits treated by lumbar spine surgery was excellent.
足下垂是腰椎疾病患者中常见且使人衰弱的症状。关于潜在疾病经手术治疗后功能恢复情况，文献中记载并不充分。本回顾性研究旨在分析55例患有足下垂且伴有椎间盘突出症和/或腰椎管狭窄症的患者在腰椎手术后术前足下垂的预后情况。术前背屈肌力有显著改善的患者占98%，肌力完全恢复的患者占71%。所有患者均伴有相关神经学表现，71%的患者症状完全消失。恢复程度与年龄、诊断结果（椎间盘突出症、腰椎管狭窄症）、症状持续时间或术前虚弱严重程度之间未发现具有统计学意义的关系。在我们的研究系列中，腰椎手术治疗术前足下垂及相关神经功能缺损的预后良好。
