Clinical Application of Large Channel Endoscopic Systems with Full Endoscopic Visualization Technique in Lumbar Central Spinal Stenosis: A Retrospective Cohort Study.

Introduction: Recently, large channel endoscopic systems and full endoscopic visualization technique have been used to perform unilateral laminotomy for bilateral decompression (ULBD) treatment for lumbar central spinal stenosis (LCSS). However, various endoscopic systems possess different design parameters, which may affect the technical points and treatment outcomes. The object of this retrospective study was to compare the efficiency, safety, and effectiveness of ULBD under the iLESSYS Delta system versus the Endo-Surgi Plus system.

Clinical evaluation of preoperative embolization, vertebroplasty, and decompression in the treatment of aggressive vertebral hemangiomas.

Objective: To evaluate the efficacy and safety of preoperative embolization and vertebroplasty in the treatment of aggressive hemangioma.

Methods: A retrospective clinical review of patients diagnosed with aggressive vertebral hemangiomas was conducted. All the patients were assigned to three groups according to the treatment strategies: patients in Group A underwent embolization and decompression with internal fixation, patients in Group B underwent vertebroplasty and decompression with internal fixation, patients in Group C received all three treatments.
