Objective: Unilateral biportal endoscopic discectomy (UBE) is an emerging and minimally invasive surgeryfor lumbar spinal degenerative disease. However, the efficacy, safety and the radiological changes of dural sac and paraspinal muscle of UBE compared with the conventional percutaneous transforaminal endoscopic discectomy (PTED) remains to be determined. The purpose of the study was to comprehensively compare the clinical efficacy between UBE and PTED in the surgical treatment of lumbar spinal degenerative disease.

Introduction: Minimally invasive techniques, such as percutaneous endoscopic discectomy, are increasingly utilized for treating focal thoracic ossification of the ligamentum flavum (TOLF), where their safety and efficacy needs to be further confirmed. The purpose of this study was to investigate the safety and efficacy of percutaneous posterolateral transforaminal endoscopic surgery under local anesthesia for treating focal TOLF.

Methods: This case series study reviewed medical records of 12 cases diagnosed with focal TOLF who underwent percutaneous posterolateral transforaminal endoscopic surgery under local anesthesia from December 2016 to July 2019 at Fuzhou Second Hospital.

Purpose: This study aims to investigate the influence of multifidus muscle fat infiltration on clinical outcomes in lumbar disc herniation (LDH) undergoing percutaneous endoscopic lumbar discectomy (PELD).

Methods: A retrospective analysis was conducted on 224 patients who underwent lateral PELD, with complete one-year follow-up data. Patients were divided into two groups based on preoperative MRI evaluation of L4 multifidus muscle fat infiltration: a mild group (< 25%) and a severe group (≥ 25%).

Objective: This study aims to evaluate the clinical benefits of the integrated optical and magnetic surgical navigation system in assisting transforaminal endoscopic lumbar discectomy (TELD) for the treatment of lumbar disc herniation (LDH).

Methods: A retrospective analysis was conducted on patients who underwent TELD for LDH at our hospital from November 2022 to December 2023. Patients treated with the integrated optical and magnetic surgical navigation system were defined as the navigation-guided transforaminal endoscopic lumbar discectomy (Ng-TELD) group (30 cases), while those treated with the conventional X-ray fluoroscopy method were defined as the control group (31 cases).

The treatment of continuous double-level lumbar degenerated disease with PE-TLIF: A case report.

Medicine (Baltimore)

January 2025

Department of Orthopaedic Surgery, Medical College, Yangzhou University, Yangzhou, China.

Rationale: Percutaneous endoscopic transforaminal lumbar interbody fusion (PE-TLIF) is a minimally invasive surgical approach for the treatment of lumbar degenerative diseases, Due to the high incidence of surgical complications and long operative time, the cases reported in previous literature were focused on single segment lumbar degenerative diseases. In our study, we present 2 patients who had continuous double-level lumbar degenerated disease.

Patient Concerns: A 71-year-old man with severe low back pain and right leg pain for 3 months, a 57-year-old woman with severe low back pain and bilateral leg pain for 6 months.
