Prospective observational cohort study. ⋯ MIS TLIF is a safe option for lumbar fusion, and when compared to open TLIF, has similar operative duration, good clinical and radiological outcomes, with additional significant benefits of less perioperative blood loss and pain, earlier rehabilitation, and a shorter hospitalization.

The purpose of this study is to assess the degenerative changes in the motion segments above a L5S1 spondylolytic spondylolisthesis and to view these in light of the retrolisthesis in the segment immediately above the slip. A spondylolytic spondylolisthesis causes an abnormal motion and predisposes to degenerative changes at the L5S1 disc. Degenerative changes in the adjacent segments would influence the symptomatology and natural history of the disease and the treatment options. The extent of degenerative changes in the levels immediately above a L5S1 spondylolytic spondylolisthesis is not well documented in the literature. We have noted retrolisthesis at this level, but this has not been previously reported or assessed. ⋯ There is a cascade of degenerative changes that involve both the disc and the facet joints at the levels above a spondylolytic spondylolisthesis. The degenerative changes at the L45 disc and a higher slip angle are consistent findings in patients with a retrolisthesis at the level above the slip.

This study aimed to improve the effectiveness of orthotic treatment for the patients with AIS using the three-dimensional clinical ultrasound (3D CUS) method in which the optimal location of pressure pad of spinal orthosis was determined with the assistance of ultrasound image analysis. ⋯ The 3D CUS could be considered as an effective, non-invasive and fast assessment method to scoliosis, especially in enhancing the effectiveness of orthotic treatment and its applications could also be further extended to other spinal deformities.
