There is no consensus for a comprehensive analysis of degenerative spondylolisthesis of the lumbar spine (DSLS). A new classification system for DSLS based on sagittal alignment was proposed. Its clinical relevance was explored. ⋯ 4.

To investigate if an association between spondylolisthesis and L5 fracture occurs in patients affected by Osteogenesis Imperfecta (O.I.). ⋯ Spondylolisthesis represents a risk factor for the development of more severe and biconcave/posterior type fractures of L5 in patients suffering from O.I., especially in type IV. This fits the hypothesis that the anterior sliding of the soma of L5 alters the dynamics of action of the load forces, localizing them on the central and posterior heights that become the focus of the stress due to movement of flexion-extension and twisting of the spine. As a result, there is greater probability of developing an important subsidence of the central and posterior walls of the soma.

Pelvic balance is a version of the pelvis defined by pelvic orientation parameters of PT and SS. Two distinct versions of pelvis are defined: (1) balanced characterized by a relatively low PT and high SS, and (2) unbalanced with relatively high PT and low SS meaning excessive retroversion of the pelvis. It was proved for patients with a high-grade spondylolisthesis that rebalancing of the pelvis can positively affect clinical outcomes. Little is known about the impact of such rebalancing in low-grade isthmic spondylolisthesis. ⋯ Radiological improvement of pelvic balance after surgical correction of mid- and low-grade isthmic spondylolisthesis did not correlate with clinical outcomes.

To assess the impact of problem and scripting-based learning (PSBL) on spine surgical trainees' learning outcomes. ⋯ The PSBL method can activate spine residents' prior knowledge and building on existing cognitive frameworks, which is an important tool for improving pre-operative preparedness. We believe that PSBL is an important first step in training spine residents to become confident and safe spine surgeons.
