Abstract:Objective:To observe the effect of Ponte osteotomy combined with multi-segment transforaminal lumbar interbody fusion (TLIF) in degenerative scoliosis. Methods: Ninety patients with degenerative scoliosis (Cobb angle of the coronal plane of the spine 25 ° ~60 °) admitted to Zhengzhou orthopedic hospital from January 2018 to December 2021 were divided into groups by a random digital table. The control group was treated with greater than or equal to grade 3 osteotomy orthopedic decompression, while the observation group was treated with Ponte osteotomy combined with multi-segment TLIF. The operation time, intraoperative bleeding volume, postoperative drainage volume, postoperative hospital stay, coronal Cobb angles, lumbar lordosis angles, apical vertebral deviation distance, lumbar dysfunction index (ODI) scores and complications were compared. Results: The operation time in the observation group was shorter than that in the control group (P < 0.05), and the amount of intraoperative bleeding and postoperative drainage were less than those in the control group (P < 0.05), and there was no statistical difference in the postoperative hospital stay (P > 0.05). At 1 month, 3 months and 6 months after operation, the coronal Cobb angles, apical vertebral deviation distance and ODI scores of the two groups were lower than those before operation (P < 0.05), and the lumbar lordosis angles were higher than those before operation (P < 0.05), and there were no significant differences in the above indexes between the two groups at different moments (P > 0.05). The incidence of complications in the observation group was lower than that in the control group (P < 0.05). Conclusion: Ponte osteotomy combined with multi-segment TLIF is effective for patients with degenerative scoliosis, which can reduce surgical trauma, accelerate postoperative rehabilitation and reduce complications.
