History: Female child, 15 days old, admitted to the hospital with the chief complaint of “lumbosacral mass found 15 days after birth”; examination: large lumbosacral mass, round-like, about 5*5cm in diameter, soft texture; examination: MRI of lumbosacral region suggests: 1. spinal cord spondylolisthesis 2. spinal cord embolism 3. spinal cord cavity at T10 level 4. spina bifida of lumbosacral segment Surgery: neurophysiological monitoring of lumbosacral spinal cord spondylolisthesis repair + spinal cord embolism release + spinal nerve root adhesion release + spinal canal expansion into the form of A, preoperative lumbosacral spinal cord spondylolisthesis mass; B, intraoperative connection neurophysiological monitoring; C, postoperative lumbosacral spinal cord spondylolisthesis mass disappeared Health Forum: 1, what is spinal cord spondylolisthesis? A: Spinal cord spinal cord bulge (meningomyelocele) is mostly seen in the lumbosacral region, often with more than 2 vertebral plate defects. The base of the cystic bulge is wide, the surface of the overlying skin is thin, pigmented and poorly translucent, and sometimes the bulging portion of the spinal cord is visible through the skin as an oval blue structure with dural vessels passing under the skin. The bursa is partially filled with spinal cord tissue and spinal nerves protruding outside the spinal canal via the spinal fissure. Most of the combined spinal cord embolism. 2.What are the dangers of spinal cord bulge? A: The neurological impairment of children with spinal cord bulge is mainly related to the developmental arrest of the neural substrate. Clinical manifestations include bilateral lower extremity motor and sensory abnormalities, urinary dysfunction; followed by Chiari II malformation, hydrocephalus, spinal cavity and scoliosis. For long-term survival patients, late neurological impairment originates from spinal cord embolism, scoliosis and other triggered foot and ankle deformities, hip dislocation, and joint adhesions and spasticity. 3.What should I do for spinal cord spondylolisthesis? A: After birth, if a newborn is found to have abnormal hair, skin flab, mass, bulge, bump, depression, small hole, pigmentation, birthmark, etc. in the lumbosacral region (i.e., the upper side of the gluteal sulcus), it is necessary to do MRI of the lumbosacral region as soon as possible to confirm the diagnosis, and for children with obvious skin features, obvious symptoms, combined with spinal cord embolism, spinal cord cavity and lipoma of spinal cord spinal cord bulge, it is necessary to perform microsurgery as soon as possible to avoid delaying The surgery should be performed under neurophysiological supervision in order to maximize the protection of normal nerves and avoid collateral damage.
