Introduction: Segmental spinal deformity results from vertebral compression fracture (VCF) and progressive collapse of the fractured vertebral body (VB). The VB stenting (VBS) system comprises a balloon-assisted, expandable, intrasomatic, metal stent that helps maintain the restored VB during balloon removal and cement injection, which minimizes cement leakage. We performed a prospective, multicenter, clinical trial of the VBS system in Japanese patients with acute VCF owing to primary osteoporosis.

- This study evaluated the effectiveness of two sagittal correction goals in corrective fusion surgery for adult spinal deformity (ASD) in patients over 65 years old, comparing the conventional "PI-LL mismatch <10°" with an alternative approach of "10°≤PI-LL≤20°".
- A total of 102 older patients were examined, divided into two groups based on their pelvic incidence-lumbar lordosis (PI-LL) measurements, with outcomes assessed over a minimum of two years.
- Results indicated no significant differences in complications or clinical outcomes between the two groups, suggesting that a less strict PI-LL mismatch threshold may be an acceptable approach in this patient population.
Introduction: Postoperative spinal epidural hematoma (PSEH) is a severe complication of spinal surgery that necessitates accurate and timely diagnosis. This study aimed to assess the accuracy of ultrasonography as an alternative diagnostic tool for PSEH after microendoscopic laminotomy (MEL) for lumbar spinal stenosis, comparing it with magnetic resonance imaging (MRI).
Methods: A total of 65 patients who underwent MEL were evaluated using both ultrasound- and MRI-based classifications for PSEH.
Objective: In this study, the authors aimed to determine the mid- to long-term outcomes of microendoscopic laminotomy (MEL) for lumbar spinal stenosis (LSS) with degenerative spondylolisthesis (DS) and identify preoperative predictors of poor mid- to long-term outcomes.
Methods: The authors retrospectively reviewed the medical records of 274 patients who underwent spinal MEL for symptomatic LSS. The minimum postoperative follow-up duration was 5 years.
Outcomes and Vertebral Osteophytes and Bulging Intervertebral Discs Occupancy as a Decision-Making Tool for Surgical Success in Patients Undergoing Microendoscopic Foraminotomy for Lumbar Foraminal Stenosis.

Objective: The objective of this study was to determine the long-term outcomes of microendoscopic foraminotomy in treating lumbar foraminal stenosis and identify the optimal extent of decompression that yields improved results and fewer complications.
Methods: A retrospective cohort study reviewed the medical records of 95 consecutive patients who underwent microendoscopic foraminotomy for lumbar foraminal stenosis. Clinical outcomes were assessed using the Japanese Orthopaedic Association scoring system and visual analog scale for low back and leg pain.
