The imaging data of a typical case of degenerative scoliosis before operation and during the follow-up period. The patient is a 65-year-old female with clinical manifestations of low back pain and intermittent claudication. A, B The anteroposterior and lateral X-rays of the whole spine before operation. C, D The anteroposterior and lateral X-rays of the whole spine immediately after operation. E, F The anteroposterior and lateral X-rays of the whole spine after 5 years of follow-up. Comparing the imaging data, it could be found that Ponte osteotomy combined with PLIF technology can effectively reconstruct lumbar lordosis and restore coronal and sagittal plane balance in patients with degenerative scoliosis, and the effects of correction can be maintained for a long time after surgery
