Effect of retention of posterior longitudinal ligament complex on Spinal deformity and motor after spinal intraspinal tumors in adult and pediatric

Abstract Backgrounds In most cases, complete resection of intranervous tumors and long-term neurological function can be achieved. However, some patients consider progressive postoperative spinal deformity as a postoperative complication. Objective We investigated that the posterior ligament complex obtained during laminoplasty can reduce spinal deformities and improve mobility, pain, and quality of life. Methods We retrospectively reviewed the data of more than 218 consecutive patients who underwent intrascleral tumor resection at one institution. The quality of life, painful cortex, spinal cord movement, progressive kyphosis or scoliosis, perioperative morbidity, and neurological results were compared in the laminoplasty and laminoplasty ligament groups. Results 155 patients underwent laminoplasty and 63 patients underwent ligament complex after laminoplasty. The patient’s age was 42 ± 2.3 years, and the average modified McCormick score was 2. There were 158 (72.4%) intramedullary tumors and 115 (52.7%) extramedullary tumors. The average residence time of the ligament complex after laminoplasty was shortened (8 days vs. 6 days; p = 0.023) and hospital recovery time (48.4% vs. 26.9%; p = 0.012). 8 cases of laminoplasty (3%) and 3 cases of laminoplasty (1%) retained posterior ligament syndrome. Progressive spinal deformities occur an average of 20 months after surgery and an average of 18 months after surgery. Spine deformity. Maintaining the posterior ligament complex during laminoplasty can improve VAS assessment and spinal mobility. Conclusion The treatment of the posterior ligament complex during laminoplasty does not significantly affect spinal deformities, but significantly improves postoperative spinal activity, pain symptoms, and hospitalization.
