Article Abstract
Aim: To compare the clinical and economic results of two different surgical approaches (bilateral decompression via unilateral approach and instrumented total laminectomy and fusion) in the treatment of lumbar spinal stenosis.
Material And Methods: The clinical, surgical, and economic aspects of 100 surgically treated patients with lumbar spinal stenosis were retrospectively reviewed.
Results: Decompression was performed at 158 levels in 100 patients. The most commonly decompressed levels were L4-5 and L3-4. Significant difference was observed between pre- and postoperative visual analog scale scores in both groups (p < 0.05). In Group 1 (instrumented total laminectomy and fusion), the mean surgery cost was 2539.2 USD (mean procedure cost: 1440.1 USD, mean implant cost: 1099.2 USD). In Group 2 (bilateral decompression via unilateral approach) the mean surgery cost was 998.5 USD. The cost difference was significant (p < 0.05).
Conclusion: Both instrumented total laminectomy and fusion and bilateral decompression via unilateral approach performed with and without stabilization showed similar clinical results in patients with lumbar spinal stenosis. However, the cost of surgery was found to be 2.5-fold higher in the instrumented total laminectomy and fusion group. This study supports the concept that minimally invasive spine surgery is cost-effective.

Is fusion to the stable sagittal vertebra necessary to avoid distal junctional kyphosis in thoracic adolescent idiopathic scoliosis?
Spine Deform
September 2025
Spine Unit, Department of Orthopedic Surgery, Rigshospitalet, Inge Lehmanns Vej 6, 2100, Copenhagen, Denmark.
Study Design: This is a retrospective single-center study.
Purpose: The purpose is to investigate the incidence of distal junctional kyphosis (DJK) when fused proximal to the stable sagittal vertebra (SSV) in adolescent idiopathic scoliosis (AIS) patients undergoing selective thoracic fusion.
Methods: We retrospectively reviewed a consecutive cohort of surgically treated AIS patients with Lenke 1-2 A/B curves between 2011 and 2022 with a minimum of 2 years of follow-up.
A Systematic Literature Review of Preference Studies in Migraine Treatments.
Patient
September 2025
PPD Evidera Patient-Centered Research, Thermo Fisher Scientific, Waltham, MA, USA.
Background: Migraine care is often suboptimal owing to undertreatment, variation in clinical outcomes and administration methods among existing treatments, and between- and within-individual heterogeneity in the clinical course of migraine. In response to these challenges, preference studies have been increasingly conducted to inform treatment decision-making and development. However, gaps remain in understanding how treatment preferences have been assessed across different migraine studies.

September 2025
Center for Perioperative Optimization, Department of Surgery, Copenhagen University Hospital - Herlev and Gentofte, Borgmester Ib Juuls Vej 1, Herlev, DK-2730, Denmark.
Purpose: Primary ventral hernia repair is a common elective procedure; however, mesh placement practices vary widely, and there is limited evidence to guide optimal placement. This international study examined surgeons' preferences and considerations regarding mesh placement in elective primary ventral hernia repair.
Methods: We conducted an international cross-sectional survey targeting surgeons experienced in primary ventral hernia repair.

Background: The purpose of the study is to evaluate the use of a magnetodynamic instrument (Magnetic Mallet, Metaergonomica, Turbigo, Milan, Italy) to perform a horizontal bone expansion in edentulous sites that need to be rehabilitated with a dental implant.
Methods: A sample of 15 patients, 11 men and 4 women, age between 39 and 78 years, was analyzed. A total of 18 conical-shaped implants with a diameter of 3.
