Clinical Effect of Vertebral Column Decancellation Osteotomy Combined with Ponte Osteotomy in Elderly Patients with Old Thoracolumbar Fracture Combined with Kyphosis Deformity

Abstract

Objective. The purpose of this study was to investigate the clinical effect of vertebral column decancellation (VCD) osteotomy combined with Ponte osteotomy in elderly patients withold thoracolumbar fracture combined with kyphosis deformity.Methods.36 elderly patients with old thoracolumbar fracture combined with kyphosis deformity admitted to our hospital from August 2015 to November 2018 were selected as the study subjects, and all of them were treated with VCDosteotomy combined with Ponte osteotomy.The Cobb angle of thoracolumbar kyphosis, sagittal vertical axis (SVA), visual analog scale (VAS) score,Oswestry disability index (ODI) and life quality were compared at 1 week before and after surgery as well as at the last follow-up. Results. ① All the 36 patients underwent the surgery successfully without serious complications, with the average duration of surgery of (5.13±0.62) h, average blood loss of (821.58±142.67) ml and average hospital stay of (14.02±2.43) d. ② The Cobb angle of thoracolumbar kyphosis and SVA at 1 week after surgery and at the last follow-up were smaller than those at 1 week before surgery (P < 0.01), but the Cobb angle of thoracolumbar kyphosis and SVA at the last follow-up were slightly larger than those at 1 week after surgery (P < 0.01). ③ The VAS score and ODI score at 1 week after surgery and at the last follow-up were lower than those before surgery (P < 0.01), and the VAS score and ODI score at the last follow-up were lower than those at 1 week after surgery (P < 0.01). ④ The scoliosis research society 22-item (SRS-22) score at the last follow-up was higher than that before surgery (P < 0.01). Conclusion. VCD osteotomy combined with Ponte osteotomy in the treatment of old thoracolumbar fracture combined with kyphosis deformity in the elderly can reduce the Cobb angle of thoracolumbar kyphosis, improve sagittal balance, reduce pain symptoms and functional disorders, and improve patients’ life quality, having a good clinical effect.
