2. 脊髓休克的临床表现有哪些?

答:损伤平面以下弛缓性瘫,肌张力低,腱反射减弱或消失,无病理征。一般持续2~4周。后期则出现肌张力增高、腱反射亢进、病理征(+)、 反射性排尿。

peripheral paralysis usually lasts for 2-4 weeks. After that, reflex activity gradually recovers and turns into central paralysis.

3. 髓内病变、髓外硬膜内病变和硬膜外病变的鉴别要点是什么?

答:早起症状,髓内为双侧,其他为一侧;神经根痛,髓外为早期;感觉障碍,髓内为分离性、马鞍回避,髓外为传导束性,开始于一侧;痛温觉,髓内在上而下发展,髓外自下而上发展,半切综合征髓外多见;阶段性肌无力和萎缩髓内早期初心,广泛明显;锥体束症髓外早期出现;括约肌功能障碍髓内病变早期出现;棘突压痛、叩痛,髓外较常见;椎管梗阻髓外早期出现,且CSF较多;脊柱X线平片改变髓外有;髓外造影出现杯口状;MRI 髓外肿块及脊髓移位,髓内梭形膨大。
