The purpose of this study is to verify if any changes occur in pelvic incidence (PI) in adult patients undergoing long fusion to sacrum for spine deformity and to describe the effect of fixation to pelvis on these variations. ⋯ Older patients undergoing long fusion to the sacrum without pelvic fixation had an increase in PI after surgery. Conversely, pelvic fixation with hips intraoperatively extended has decreased the value of PI from pre- to early postoperative. These changes could be related to degeneration of the sacroiliac joints causing increased rotational mobility and the magnitude of the differences is in the range of clinical relevance.

Using MR imaging, nerve root sedimentation sign (SedSign) was demonstrated to have a high sensitivity and specificity for diagnosis of symptomatic lumbar spinal stenosis (LSS) in selected patients. This study was to evaluate the diagnostic value of SedSign in differential diagnosis of LSS and non-specific low back pain (LBP) in consecutive patients. ⋯ The present data demonstrated that the SedSign was not able to discriminate symptomatic LSS from non-specific LBP after adjusting by dural sac CSA. The diagnostic value of the SedSign was still uncertain.

To examine the radiological and clinical outcomes of a single-center case series of selective thoracic fusions (STF) in adolescent idiopathic scoliosis with Lenke C modifier curves, with a long-term follow-up. ⋯ STF is an effective treatment option both in clinical and radiographical terms. The results at 10-year follow-up confirm both the stability of the correction and the improvement of the clinical outcome scores. Risser and Lenke grading systems are not relevant variables predictive of clinical efficacy.

Purpose Thoracic disk herniation is uncommon. It still represents a challenge for spinal surgeons. Multiple surgical strategies are available and, often, they are matter of debate. We describe a preliminary experience about a combined extra-intra dural approach for posterolateral disk herniation in patients affected by spinal cord compression.
