Few studies have examined the effectiveness of surgical treatment for adult degenerative scoliosis (ADS) using validated patient-orientated outcome instruments. This study reports patient outcomes in a large, consecutive series of patients being treated for ADS by simple decompression (D), short fusion (SF), or long fusion (LF). ⋯ Despite the complexity of the disease, patient-orientated outcomes after surgery for ADS were similar to those previously reported using the same outcome instruments in patients with lumbar stenosis and degenerative spondylolisthesis. The use of D, SF and LF for ADS yielded similarly good results from the patient's perspective. This most likely reflects careful and appropriate patient selection. Further analyses are warranted to identify baseline variables predicting the 26-31 % cases in each group with a poor outcome.

To investigate the epidemiology of radiographic degenerative lumbar scoliosis (DLS) and symptomatic DLS and clarify the impact of radiographic spinopelvic parameters on the presence of symptoms and quality of life (QOL) in DLS subjects. ⋯ The prevalence of radiographic DLS in this study was approximately 20 % and roughly 40 % of the DLS subjects had symptoms. Some spinopelvic parameters may impact the occurrence of symptoms and the QOL in DLS subjects.

Sagittal vertical axis (SVA) is the most commonly used parameter for evaluating global sagittal alignment (GSA) in a static condition. However, its dynamic statuses remain unclear. The aim of this study was to evaluate dynamic GSA of degenerative lumbar kyphoscoliosis (DLKS) using three-dimensional motion analysis system (3D-MAS). ⋯ Dynamic GSA assessment using 3D-MAS can avoid underestimation of GSA loss that is detected by static standing full-length radiography.
