Acute herniation of nondegenerate nucleus pulposus material is an important and relative common cause of acute spinal cord dysfunction in dogs. Two types of herniation of nondegenerate or hydrated nucleus pulposus have been recognized: acute noncompressive nucleus pulposus extrusion (ANNPE) and acute compressive hydrated nucleus pulposus extrusion (HNPE). Spinal cord contusion plays an important role in the pathophysiology of both conditions. Sustained spinal cord compression is not present in ANNPE, whereas varying degrees of compression are present in HNPE. Although affected animals often present with severe neurologic signs, good outcomes can be achieved with appropriate treatment.
非退变髓核物质的急性疝出是犬急性脊髓功能障碍的一个重要且相对常见的原因。已认识到非退变或含水髓核的两种疝出类型：急性非压迫性髓核突出（ANNPE）和急性压迫性含水髓核突出（HNPE）。脊髓挫伤在这两种情况的病理生理学中都起重要作用。ANNPE不存在持续性脊髓压迫，而HNPE存在不同程度的压迫。尽管患病动物通常表现出严重的神经症状，但通过适当治疗可取得良好预后。
