Retrospective study of prospectively collected data. ⋯ Avulsion-type herniations in patients aged <50 years had a higher CE occupancy rate, which is a potential cause of preoperative motor weakness. Clinical outcomes following discectomy improved regardless of the presence of CEs, however, cartilaginous herniation in patients aged ≥50 years may affect residual LBP at 1 year.

Retrospective multicenter cohort study. ⋯ We saw a small increase in thoracic kyphosis in the NTB group vs. a small decrease in the FTB group. Eight percent in the NTB group vs 24% in the FTB group showed substantial hypokyphosis after bracing. The impact of minor changes in thoracic kyphosis remains uncertain; however, a threefold difference in the occurrence of hypokyphosis is notable and merits further attention.

Randomized Controlled Trial Multicenter Study Comparative Study
Efficacy of Biphasic Calcium Phosphate Ceramic With a Needle-shaped Surface Topography Versus Autograft in Instrumented Posterolateral Spinal Fusion: A Randomized Trial.
A multicenter randomized controlled noninferiority trial with intrapatient comparisons. ⋯ This clinical trial demonstrates noninferiority and indicates superiority of MagnetOs Granules as a standalone ceramic when compared to autograft for posterolateral spinal fusion. These results challange the belief that autologous bone is the most optimal graft material.
