Percutaneous endoscopic discectomy (PED) for lumbar disc herniation is gaining popularity with the transforaminal (TF) approach preferred because it allows surgery under local anesthesia and preserves the spinal muscles. Although this procedure has some characteristic complications, it is rare for PED to be converted to conventional open surgery due to worsening of symptoms intraoperatively. Here, we report PED via the TF approach that required conversion to open surgery. A 20-year-old man with a large disc herniation at L3/4 developed severe progressive leg pain and muscle weakness of the left leg intraoperatively...

OBJECTIVES: Percutaneous endoscopic lumbar discectomy (PELD) has become a mature and mainstream surgical technique for treating lumbar disc herniation (LDH); however, there is a steep learning curve with PELD, especially for puncture and foraminoplasty. In this study, we assessed the outcome and safety of a novel quantificational and targeted foraminoplasty device named ZESSYS for LDH. METHODS: From September to December of 2016, 70 patients with symptomatic LDH were enrolled in the study...

The objective of this study is to introduce a method using a percutaneous full-endoscopic interlaminar approach via a surrounding nerve root discectomy (SNRD) operative route that involves removing the protrusive disc via both the shoulder and the axilla of the corresponding nerve root for the treatment of ventral-type lumbar disc herniation (VLDH) and its early clinical symptoms. Twenty-two patients with VLDH satisfied the inclusion criteria and underwent the full-endoscopic interlaminar approach operation via a SNRD successfully during the period from November 2014 to June 2016...

BACKGROUND: The endoscopic approach has been introduced in the clinical practice in 1980 with the aim to remove the pro- lapsed disk and free the compressed nerve using the least disruptive surgical technique, assuring in the same time, the resolution of the symptoms and a faster return back to normal life activity. Over the years, thanks to an extraordinary technical improvement either in terms of quality of images and development of many dif- ferent tailored instrumentations there has been a huge spreading of the endoscope use across the different surgical fields...

BACKGROUND: Percutaneous endoscopic discectomy (PED) includes 2 main procedures: percutaneous endoscopic lumbar discectomy (PELD) and percutaneous endoscopic interlaminar discectomy (PEID), both of which are minimally invasive surgical procedures that effectively deal with lumbar degenerative disorders. Because of the challenging learning curve for the surgeon and the individual characteristics of each patient, preventing and avoiding complications is difficult. The most common complications, such as nucleus pulposus omission, nerve root injury, dural tear, visceral injury, nerve root induced hyperalgesia or burning-like nerve root pain, postoperative dysesthesia, posterior neck pain, and surgical site infection, are difficult to avoid; however, more focus on these issues perioperatively may be in order...

REVIEW
Ovidiu Palea, Michelle Granville, Robert E Jacobson
The clinical effectiveness of percutaneous and transforaminal endoscopic discectomy procedures has been evaluated by the system used or compared to open laminectomy or micro-discectomy but are not evaluated based on the location and characteristics of the abnormal disc. This review proposes that outcomes are primarily related to disc size, biomechanics, location, and associated segmental fibrotic and bone changes as well as the surgeon's skill in using various systems rather than the specific system used...

BACKGROUND: In the last decades, full-endoscopic techniques to treat lumbar disc herniation (LDH) have gained popularity in clinical practice. However, few studies have described the safety and efficacy of percutaneous transforaminal endoscopic discectomy (PTED) in treating younger patients with LDH. This study aims to evaluate the preliminary surgical outcome and complication of PTED in treating younger patients with LDH. METHODS: Between June 2012 and June 2016, 72 young patients (< 45 years old) who underwent PTED for single-level LDH were prospectively followed up...

BACKGROUND: Anterior percutaneous endoscopic transcorporeal cervical discectomy (APETCD) is an alternative operation for cervical disc herniation. However, few reports have evaluated the biomechanical influence of tunnels on vertebrae. We compared biomechanical distinctions between intact and tunneled models to analyze the safety of APETCD based on a C2-T1 finite element(FE) model. METHODS: Two groups of C2-T1 FE models were simulated with C4 tunneled by two methods (A: with partial superior endplate excision, B: without partial superior endplate excision) and various tunnel diameters (6mm, 8mm, 10mm)...

BACKGROUND CONTEXT: L5-S1 transforaminal PELD is a demanding procedure due to structures like iliac crest, L5 transverse process, hypertrophic L5-S1 facet joint, and sacral ala. There has been no definite preoperative evaluation method to evaluate the surgical validity of L5-S1 transforaminal PELD. PURPOSE: Authors report a new preoperative trajectory evaluation method for L5-S1 transforaminal PELD using magnetic resonance imaging (MRI) or computed tomography (CT) examinations STUDY DESIGN/SETTING: Technical Reports PATIENT SAMPLE: Patients who were diagnosed as L5-S1 soft disc herniation OUTCOME MEASURES: Success rate of transforaminal PELD according to height of iliac crest METHODS: Twelve patients who were diagnosed L5-S1 disc herniation were preoperatively evaluated with this new method...

PURPOSE: During the long-term practice of percutaneous endoscopic cervical discectomy (PECD) at our institution, we have modified the protocol to include the vertical anchoring technique (VAT), which we will describe in detail in this article. The objective of this study was to compare the clinical outcomes associated with the conventional posterior PECD technique with that associated with the modified technique to determine the safety and efficacy of the latter technique. METHODS: From December 2014 to January 2016, a total of 44 patients with single cervical disc herniation were randomly divided into two groups...

Intervertebral disc degeneration (IVDD) is one of the key predisposing factors for low back pain. Although the exact mechanism remains unclear, inflammatory response and nucleus pulposus (NP) apoptosis are known to play important roles in this process. Prolactin protects against inflammation-associated chondrocyte apoptosis in arthritis. Based on prior studies, we hypothesized that prolactin might have therapeutic effects on IVDD by inhibiting the apoptosis of degenerative human disc NP cells. An experimental model of IVDD was established in 3-month-old Sprague-Dawley rats by submitting them to percutaneous disc puncture with a 20-gauge needle on levels 7-8 and 8-9 of the coccygeal vertebrae...
