Spinal surgery for adult spinal deformity (ASD) may require the use of osteotomies, which may have high complication rates (up to 80 %). These may be expected to affect health-related quality of life (HRQOL) in the early postoperative phase but little is known about the clinical course of these patients in the first year following surgery. The aim of the study is to evaluate the radiological results and HRQOL in patients undergoing a spinal osteotomy for ASD within the first year following surgery with special reference to the effect of complications. ⋯ Osteotomies were moderately effective in radiological improvement but resulted in a significant increase in HRQOL. They were associated with a high rate of complications but these had no/minimal effect on the clinical outcome. Contrary to the general perception, the greatest improvements in HRQOL were seen to take place during the first 6 months after surgery, even in the presence of complications.

Pedicle subtraction osteotomy (PSO) is widely used to treat severe fixed sagittal imbalance. However, the effect of PSO on balance has not been fully documented. The aim of this study was to assess dynamic walking balance after PSO to treat fixed sagittal imbalance. ⋯ Despite a mild residual spinal-pelvic malalignment, PSO restored sagittal alignment and balance satisfactorily and has improved the gait pattern.

To determine the correlation of the difference between postoperative lumbar lordosis (LL) and ideal LL with the sagittal vertical axis (SVA) at the final follow-up in patients with adult spinal deformity (ASD). ⋯ Overcorrection of LL is an effective treatment modality to maintain optimal sagittal alignment in patients with DLK; this suggests that it should be considered in preoperative planning for patients with ASD with sagittal imbalance.

Most morphometric studies on lumbar degenerative spondylolisthesis (DS) have focused solely on the L4-L5 slipped level, neglecting the shape of the entire lumbar segments. The purpose of this study was to present a morphometric analysis of the entire lumbar IVDs and VBs in DS. ⋯ Individuals with DS have a more generalized degenerative disc disease on all lumbar vertebral levels, characterized by decreased disc space heights and kyphotic posture of the upper lumbar segments, occurring more predominantly in females than in males with DS.
