Abstract:
Objective:To investigate the clinical value of short segment fusion and long segment fusion combined with posterior pedicle screw system internal fixation in the treatment of degenerative scoliosis.Methods:74 patients with degenerative scoliosis who were treated in the Affiliated Hospital of Southwest Medical University from January 2014 to February 2018 were enrolled in the study. The patients were divided into group A and group B with a random number table of 37 cases each. Group A was treated with short segment fusion and posterior pedicle screw system internal fixation, while group B was with long segment fusion and posterior pedicle screw system internal fixation. The Cobb angle of scoliosis, the balance of coronal and sagittal plane of spine were observed before operation, 1 week after operation, 3 months after operation and 6 months after operation, and the incidence of early and long-term complications were counted.Results:The Cobb angle of scoliosis in group B was lower than that of group A at 1 week, 3 months and 6 months after operation ( P<0.05). There was no significant difference in the balance of coronal plane and sagittal plane between the two groups at 1 week and 3 months after operation ( P>0.05). There was significant difference in the balance of coronal plane and sagittal plane between the two groups at 6 months after operation ( P<0.05). There was no significant difference in the incidence of early postoperative complications between the two groups ( P>0.05). Conclusions:Long segment fusion and posterior pedicle screw system internal fixation can improve the Cobb angle and reduce the incidence of postoperative scoliosis, but it is easy to appear the imbalance of coronal and sagittal planes, which can be selected according to the actual situation.
