To investigate the microstructural changes in compressed nerves using diffusion tensor imaging (DTI) of herniated disc treated with percutaneous transforaminal endoscopic discectomy.Diffusion tensor imaging has been widely used to visualize peripheral nerves, and the microstructure of compressed nerve roots can be assessed using DTI. However, the microstructural changes after surgery are not well-understood in patients with lumbar disc herniation.Thirty-four consecutive patients with foraminal disc herniation affecting unilateral sacral 1 (S1) nerve roots were enrolled in this study...

Endoscopic surgery for lumbar disc herniation has been available for more than 30 years. Transforaminal percutaneous endoscopic lumbar discectomy is a well-known, safe, and effective method used for the treatment of the lumbar disc herniation. The published complications of the transforaminal percutaneous endoscopic lumbar discectomy consist of infections, thrombophlebitis, dysesthesia, dural tear, vascular injury, and death. Seizure after transforaminal percutaneous endoscopic lumbar discectomy is an extremely rare complication...

OBJECTIVE: Herniated disc tissue removal to decompress the spinal nerve/cauda equina. Minimization of iatrogenic trauma and associated injuries. INDICATIONS: Conservative treatment did not sufficiently improve clinical symptoms. This is true for progressive or persisting neurological deficits, as well as for persisting pain which alters the quality of the patient`s life. Results of surgery are strongly dependent on the preoperative duration of symptoms. Paramount is the "timing" of surgery: poorer surgical results associated with increasing preoperative duration of symptoms...

BACKGROUND: Percutaneous endoscopic lumbar discectomy (PELD) is a standard technique for the treatment of lumbar disc hernia. Thus far, most surgeons have recommended local anesthesia. However, in clinical practice, some patients experience pain and are unable to cooperate with the surgery during intervertebral foramen hemp expansion. The use of general anesthesia may create a greater risk of complications because of nerve root anomalies; thus, intraoperative neurophysiological monitoring should be utilized...

STUDY DESIGN: A case-control study. PURPOSE: To investigate the effectiveness of transforaminal percutaneous endoscopic discectomy (TPED) in Parkinson's disease (PD). OVERVIEW OF LITERATURE: Patients with PD frequently suffer from radiculopathy and low back pain. Additionally, they demonstrate higher complication rates after open spine surgery. However, the clinical outcome of minimally invasive techniques for lumbar discectomy, such as TPED, have not been established for this population...

OBJECTIVE: Endoscopic surgery for highly migrated lumbar disc extrusions is a challenge even for spine surgeons who are very familiar with utilizing endoscopic techniques. Because of the anatomic constraints involved in transforaminal access in endoscopic surgery, an incomplete removal of a highly migrated disc extrusion can result in some cases. Here the authors describe a new technique for accessing extruded lumbar discs that have migrated into the canal directly through a transpedicular approach...

STUDY DESIGN: A prospective, randomized, controlled study of patients with L5-S1 lumbar disc herniations, operated with endoscopic discectomy through an interlaminar or transforaminal approach. OBJECTIVE: To compare the results of percutaneous endoscopic lumbar discectomy in L5-S1 disc herniation through an interlaminar or transforaminal approach. SUMMARY OF BACKGROUND DATA: The transforaminal and interlaminar techniques are both acceptable approaches for L5-S1 disc herniation...

BACKGROUND: Obese patients are at risk of complications such as slower wound healing and increased infection rates after spinal surgery. Transforaminal full-endoscopic lumbar discectomy (ELD) has advantages over conventional microdiscectomy because it decreases perioperative complications and increases favorable clinical outcomes. No clinical studies have reported ELD in obese patients. The purpose of this study is to evaluate the clinical outcomes of transforaminal ELD in obese patients...

BACKGROUND This study aimed to evaluate the efficacy of transforaminal endoscopic discectomy (TED) in the treatment of obese patients with lumbar disc herniation (LDH). MATERIAL AND METHODS A total of 69 obese patients with LDH (35 males and 34 females; age range, 24 to 43 years; median age, 34 years) were included in this study. These patients had undergone TED from March 2011 to December 2015 in the Third Hospital of Hebei Medical University. Their clinical and follow-up data were prospectively analyzed. The degree of pain and disability were measured on the basis of the Visual Analog Scale (VAS) at 1 day before surgery, immediately after surgery, and 3 months after surgery...

OBJECTIVES: This study aimed to compare the learning curves of percutaneous endoscopic lumbar discectomy (PELD) in a transforaminal approach at the L4/5 and L5/S1 levels. METHODS: We retrospectively reviewed the first 60 cases at the L4/5 level (Group I) and the first 60 cases at the L5/S1 level (Group II) of PELD performed by one spine surgeon. The patients were divided into subgroups A, B, and C (Group I: A cases 1-20, B cases 21-40, C cases 41-60; Group II: A cases 1-20, B cases 21-40, C cases 41-60)...

BACKGROUND: Full-endoscopic operations of lumbar spine are truly minimally invasive surgical procedures. Endoscopic techniques have become the standard in many areas because of the advantages they offer intraoperatively and after surgery. With the interlaminar and transforaminal approach, two full-endoscopic procedures are available for lumbar compressive lesion operations. Our aim was to present and explain all aspects of the full-endoscopic operative technique, and presentation of results of lumbar discectomies and monosegmental decompression in full-endoscopic interlaminar technique performed during 3 year period in comparison with conventional microsurgical operations reported in literature...

OBJECTIVES: Transforaminal percutaneous endoscopic lumbar discectomy (PELD) for high-grade migrated disc herniation has been regarded as a challenging task, but because of the remarkable improvement in navigable instruments and advanced epiduroscopic technique, it can be used for the treatment of high- or very high-grade migrated disc herniation. The purpose of this study was to describe in detail the standardized technique of transforaminal PELD for very high-grade migrated disc herniation and demonstrate the clinical results...

UNLABELLED: The technique of percutaneous endoscopic lumbar discetomy (PELD) in the transforaminal approach has evolved over the years due to the advances in endoscopic photology and instrumentation and become the most popular technique for lumbar disc herniation. Although PELD offers many advantages, the indications of PELD are limited mostly to non-migrated or low-migrated disc herniation. It is very difficult for PELD in the transforaminal approach to remove the highly migrated disc fragment successfully due to the anatomic barrier...
