Spinal fissure and double stem spinal cord surgery

The spinal cord is divided into two halves of the spinal cord enclosed in a dura mater with a soft fibrous septum in the middle; the double trunk spinal cord is a pair of juxtaposed spinal cords, each wrapped by a dural tube, with a middle Hard bone partition. About 80% of patients with this type of malformation have symptoms of tethered cord disease and require surgery. Treating diseases: spina bifida and related malformations Indication Spinal fissure and double trunk spinal surgery are suitable for: Congenital spinal cord longitudinal deformity complicated with neurological dysfunction, confirmed by MRI. Contraindications No special contraindications. Preoperative preparation The skin is cleaned daily from 3 days before surgery to prevent the stool from contaminating the surgical area. Those with abnormal hair should be cleaned. Surgical procedure 1. Incision Midline incision in the back. 2, laminectomy. 3, dural midline incision exploration It can be found that the spinal cord divides into two halves, and there are osteophytes in the fissures of the double-stem spinal cord. The middle of the longitudinal fissure of the spinal cord is fibrous septum, and local multiple adhesion. 4, double dry spinal cord and spinal cord longitudinal fissure treatment Under microsurgery, if the dural spinal cord divides the medial part of the spinal canal from the epiphysis around the epiphysis, use a high-speed micro drill to remove the callus, or carefully remove the callus with a small bone chisel. The inner wall of the two dural cannulas is removed, the adhesion is removed to remove the tethered line, and the outer part of the two hard spinal membranes is sutured into a dural tube; if the spinal cord is longitudinally split, the midline fiber is removed and examined. Unlink the system. 5. Strictly suture the dural, muscular layer, subcutaneous tissue and skin. The wound is pressure bandaged. complication Improper free spinal cord can cause spinal cord injury and aggravate neurological dysfunction.
