Foot drop is a condition that can substantially add to the disability of patients with degenerative lumbar spinal disorders. The most common degenerative conditions associated with foot drop are lumbar disc herniation and lumbar spinal stenosis. The level most commonly affected is the L4/5 spinal level. Most patients are treated with surgery, although there is insufficient evidence to support that surgery is superior to conservative therapy. In most surgical patients, foot dorsiflexion will improve to some degree. The preoperative power of foot dorsiflexion is the key factor associated with prognosis.
足下垂是一种会显著加重退行性腰椎疾病患者残疾程度的病症。与足下垂相关的最常见退行性病症是腰椎间盘突出症和腰椎管狭窄症。最常受影响的节段是腰4/5节段。大多数患者接受手术治疗，尽管没有足够证据支持手术优于保守治疗。在大多数接受手术的患者中，足背屈会有一定程度的改善。术前足背屈的肌力是与预后相关的关键因素。
