Background: Here, we evaluated the failure to preserve or restore adequate spinopelvic alignment following lumbosacral instrumented fusions for degenerative disease.
Methods: Patients undergoing lumbosacral instrumented fusions for degenerative spine disease underwent; standing lumbopelvic X-rays and lumbar MRI scans obtained both preoperatively and 1 year postoperatively. Parameters measured included lumbar lordosis (LL), L4-S1 angle, pelvic incidence (PI), and LL-PI mismatch.
Results: Fifty patients were followed for 1 year following lumbopelvic fusion. There was a statistically significant difference in the L4-S1 angle between patients with good versus poor clinical outcomes at 1 year postoperative; the LL-PI mismatch showed a strong positive correlation with better outcome scores.
Conclusion: Preservation of an adequate LL/other lumbosacral parameters favorably impacts patients' outcomes following lumbosacral fusion for degenerative disease.

Article Synopsis
- The choice of the lower vertebra for spinal fixation in adult spinal deformity, particularly around the lumbosacral junction, is debated, with options including stopping fixation at S1 or using lower points like S2AI or iliac screws to prevent implant pullout.
- A new technique for posterior fixation combines S1 screws, iliac screws, and sacro-iliac implants, inspired by triangular pelvic fixation methods used for trauma.
- This study outlines the operative technique using fluoroscopic guidance and shares preliminary results from treating 15 patients, labeled as level IV evidence.

Objective: To analyze the safety and effectiveness of 3D printing prefabricated nail path model assisted lumbosacral hemivertebra orthopaedic surgery.
Methods: A retrospective analysis was performed on 8 patients with lumbosacral hemivertebra deformity admitted from January 2016 to July 2021, including 3 males and 5 females, aged 6 to 15 at the time of surgery. The hemivertebra of 4 cases located on the left side and 4 cases on the right side.
Comparison of three sacral screw internal fixation techniques in the treatment of L4-S1 lumbar degenerative disease with osteoporosis: a retrospective observational study.

Article Synopsis
- This study compares the effectiveness of three different fixation methods for treating lumbar degenerative disease in patients with osteoporosis: PMMA-augmented pedicle-screw fixation, bicortical fixation, and tricortical fixation.
- Patients in all groups showed significant improvement in pain and disability scores post-surgery, but those using PMMA had better outcomes, including lower rates of screw loosening.
- The findings suggest that PMMA augmentation enhances screw stability in lumbosacral fusion for these patients, making it a recommended surgical approach.
Fractional curve following adult idiopathic scoliosis correction: impact of curve magnitude on postoperative outcomes.
J Neurosurg Spine
November 2024
1Department of Orthopedic Surgery, Warren Alpert Medical School of Brown University, Providence, Rhode Island.
Objective: The goal of this study was to assess the impact of fractional curve (FC) severity on curve progression and postoperative outcomes in patients undergoing adult idiopathic scoliosis (AdIS) correction.
Methods: Patients with AdIS who had preoperative coronal plane deformity and who had undergone thoracolumbar fusion with a lowermost instrumented vertebra (LIV) between L1 and L4 were included. Patients were stratified by 6-week postoperative FC severity (small FC, ≤ 40th percentile, large FC, ≥ 60th percentile of the entire cohort; calculated as the Cobb angle between LIV and S1) and age groups.
Incidence and Risk Factors of Lumbosacral Complications Following Long-Segment Spinal Fusion in Adult Degenerative Scoliosis.

Department of Orthopedic Surgery, Beijing Chao-Yang Hospital, Capital Medical University, Beijing, China.
Purpose: Long-segment spinal fusions are associated with lumbosacral complications (LSC), but the associated risk factors are not known. This study aimed to identify the risk factors for LSC after long-segment instrumented fusion with distal fixation to the L5 vertebral body in adult degenerative scoliosis (ADS).
Methods: We retrospectively evaluated 294 patients with ADS who underwent long-segment floating fusion between January 2014 and March 2022, with follow-up for at least 2 years.
