Effect of simultaneous surgical treatment in scoliosis associated with intraspinal abnormalities: A retrospective study.

To evaluate the outcomes of single-stage surgical treatment for spinal deformity and coexisting intraspinal pathologies, 12 patients who underwent single-stage surgical treatment for spinal deformity and co-existing intraspinal abnormalities between October 2016 and January 2017 were enrolled in the present study. Treatment for intraspinal abnormalities, posterior correction, osteotomy and internal fixation were performed simultaneously. The clinical and radiological outcomes, surgical details, complications and postoperative outcomes were evaluated. The mean fusion length was 11.0±2.8. Both scoliosis Cobb angle (pre-surgery 65.9±13.4 vs. post-surgery 21.7±9.4) and kyphosis (pre-surgery 71.1±19.5 vs. post-surgery 31.4±10.4) were significantly improved post-surgery. Tethered cords were released and epidermoid cysts, gangliogliomas, meningiomas and lipomas were resected. Muscle strength in all patients was improved. The muscular tone of 8 patients was improved. No severe complications occurred postoperatively. None of the patients experienced deterioration in their neurological status nor loss of correction during the 12-24 months' follow-up. The simultaneous surgical treatment for spinal deformity and intraspinal pathology seems to be a safe and effective approach. Neurological deficits were improved postoperatively. Osteotomy produces satisfactory correction results.
