BACKGROUND
Percutaneous radiofrequency nucleoplasty is a true minimally invasive technique for treatment for radiculopathy caused by contained disc protrusions. This minimally invasive procedure uses controlled thermoablation for reducing the intervertebral disc and decompressing the lumbar nerve root. Material and Methods: Our study is a prospective analysis of 27 patients aged from 30 to 64 years with lumbar disc protrusion who were treated with percutaneous radiofrequency disc decompression (PRFD) between May 2018 and May 2019. Clinical follow-up was reported at 1 month, 3 months, and 6 months. The outcomes were assessed using a visual analog scale (VAS) and MacNab score.
RESULTS
Of the 27 patients, 14 were female and 13 were male. Their mean age was 53 ± 2 years. In all 27 patients, percutaneous radiofrequency nucleotomy was performed. An excellent outcome as reflected by MacNab score was observed in 17 patients (63%), a good outcome in 8 patients (29.7%), and a poor outcome in 2 patients (7.3%). Prior to treatment, the average back and leg VAS scores were 7.95 and 7.82, respectively. At sixth month follow-up, the back and leg VAS scores were reduced to 3.17 and 3.04, respectively. Patients with a poor outcome developed early recurrent disc prolapse and required endoscopic discectomy.
CONCLUSION
PRFD is a safe and effective treatment of contained disc protrusion. PRFD is a good alternative to surgery. These procedures significantly increase quality of life in patients with lumbar radiculopathy.

Risk Factors and Causes of Reoperation in Lumbar Disc Herniation Patients after Percutaneous Endoscopic Lumbar Discectomy: A Retrospective Case Series with a Minimum 2-Year Follow-Up.
BACKGROUND Percutaneous endoscopic lumbar discectomy (PELD) has gained popularity as a minimally invasive surgery for treating lumbar disc herniation. However, there is limited research focusing on the reoperation rate and its associated factors. This study aims to investigate the rate of reoperation and identify the causes and risk factors for reoperation after PELD. MATERIAL AND METHODS We conducted a retrospective analysis of patients who underwent PELD (interlaminar and transforaminal approaches) at our hospital from November 2016 to May 2020. A matched case-control design was employed to identify relevant risk factors for reoperation, with a matching ratio of 1:3. Clinical characteristics and radiological parameters were compared, and univariate analysis was performed using independent samples t-test and chi-squared test. RESULTS Among the 435 patients included in the study, the reoperation rate for those with a minimum 2-year follow-up was 6.2% (27/435). The causes of reoperation and their respective rates were as follows: recurrence of lumbar disc herniation (3.2%, 14/435), incomplete decompression (1.8%, 8/435), persistent low back pain (0.7%, 3/435), and postoperative infection (0.5%, 2/435). Univariate analysis revealed that age (P=0.015), Pfirrmann grade IV-V (P=0.017), and lack of active straight leg raise exercises (P=0.026) were significantly associated with reoperation. Multiple logistic regression analysis indicated that age (P=0.001), Pfirrmann grade IV-V (P=0.033), and lack of active straight leg raise exercises postoperatively (P=0.003) were independent risk factors for reoperation after PELD. CONCLUSIONS The primary cause of reoperation in lumbar disc herniation patients after PELD was recurrence of the herniation. Additionally, severe disc degeneration, older age, and lack of active straight leg raise exercises were identified as significant risk factors associated with an increased reoperation rate.

OBJECTIVE
To determine the safety and efficacy of percutaneous endoscopic lumbar discectomy (PELD) combined with platelet-rich plasma (PRP) hydrogel injection in patients with lumbar disc herniation (LDH).
METHODS
A total of 98 consecutive patients with LDH who underwent either PELD combined with PRP hydrogel injection or PELD alone were reviewed. This retrospective study was performed between January 2019 and January 2021. Clinical outcomes were compared in the visual analog scale (VAS) for low back pain and leg pain, Oswestry disability index (ODI), Japanese Orthopaedic Association (JOA) scores, and Macnab criteria. Intervertebral disc height on MRI was measured, and the Pfirrmann grade classification was used pre-operatively and post-operatively.
RESULTS
No severe adverse events were reported during an 18-month follow-up period. VAS scores for back pain were decreased at 1 month, 3 months, and 18 months in the treatment group than that in the control group. JOA score and ODI in the treatment group at 3-month and 18-month follow-up was lower than that in the control group (P < 0.05). The excellent and good rate of the Macnab criteria was 92.0% (46/50) in the treatment group and 89.6% (43/48) in the control group (P > 0.05). The comparison of Pfirrmann grading and disc height at 18-month follow-up showed significant difference in two groups (P < 0.05). The recurrence of LDH in the treatment group was lower than that in the control group (P < 0.05).
CONCLUSIONS
We suggest that PELD combined with PRP hydrogel injection to treat patients with LDH is a safe and promising method. PRP injection was beneficial for disc remodelling after PELD.

OBJECTIVE
This study aimed to report our experience with spinal anesthesia (SA) in patients undergoing L5-S1 interlaminar endoscopic lumbar discectomy (IELD) and clarify its advantages and disadvantages.
METHODS
One hundred twelve patients who underwent IELD for an L5-S1 disc herniation under SA were retrospectively analyzed. SA with 0.5% ropivacaine was administered using a 27-gauge fine needle. Intraoperatively, the volume and level of SA, surgical time, blood loss, and cardiopulmonary complications were documented. Postoperative data was collected included the number of patients who ambulated on the day of surgery, incidence of complications and were then statistically analyzed.
RESULTS
Analgesia was complete throughout the entire operation in all patients and no other adjuvant intraoperative analgesic drugs were needed. Mean visual analog scale scores for intraoperative and early postoperative (24 h) pain were 0 and 2.43 ± 1.66. SA was administered at the L3-4 interspace in 34 patients (30.4%) and the L2-3 interspace in 78 (69.6%). Administration was successful with the first attempt in all patients. Mean operation time was 70.12 ± 6.52 min. Mean intraoperative blood loss volume was 20.71 ± 5.26 ml. Ninety-eight patients ambulated on the same day as surgery. Mean length of hospital stay was 24.36 ± 3.64 h. Dural injury without damaging the nerve root occurred in one patient. One patient experienced recurrent disc herniation. Intraoperative hypotension and respiratory distress occurred in five (4.5%) and three (2.7%) patients, respectively. Three patients (2.7%) received postoperative analgesia therapy and two (1.8%) experienced nausea. Two patients (1.8%) developed urinary retention. Spinal headache, cauda equina syndrome, and neurotoxicity did not occur.
CONCLUSION
SA can achieve satisfactory pain control for patients undergoing IELD with a low incidence of adverse events. SA may be a useful alternative to local and general anesthesia for IELD surgery. Future randomized controlled trials are warranted to investigate.

Review
OBJECTIVE
Lumbar disc herniation (LDH) is a common pathology that typically causes unilateral radiculopathy on the same side as herniation, while patients may occasionally present with contralateral symptoms. Owing to the rare incidence of LDH with contralateral symptoms, the pathological mechanism remains unclear and the optimal surgical strategy is a subject of debate. This study aimed to provide new insights into the pathological mechanism of contralateral symptoms and assess the efficacy of ipsilateral hemilaminectomy and discectomy surgery in this population.
METHODS
This study was a retrospective, single-center, clinical case series, including 11 LDH cases with exclusive contralateral symptoms. We searched for LDH cases that were presented at our institution between January 2011 and December 2020. Adult LDH Patients with contralateral radicular pains were included, while those with ipsilateral radiculopathy, lumbar stenosis, foraminal stenosis on the symptomatic side, multilevel disc herniations, scoliosis, and lumbar operation history were excluded. Visual Analog Scale (VAS), clinical features, radiographic images, and other data were collected from the study cohort of 11 cases for further analysis. We also reviewed LDH cases in English literature from 1978 to 2023 to analyze their clinical characteristics and treatment.
RESULTS
The incidence rate of LDH with contralateral symptoms in single-level LDH cases was 0.32%. The average age of our 11 cases was 49.3 years old, and five of them were female (45.5%). All individuals had single-level lateral LDH, with six cases (54.5%) located at L4-5 and five cases (45.5%) located at L5-S1. Upon admission, patients presented with lower back pain (seven cases, 63.6%), radicular pain (seven cases, 63.6%), hypoesthesia (seven cases, 63.6%), and muscle weakness (one case, 9.1%) on the contralateral side alone. Each case experienced ipsilateral hemilaminectomy and discectomy, and no lateral recess stenosis, hypertrophy of facets or ligaments, and sequestrated discs were found during surgery. All of them have good pain relief with two cases reporting no pain and nine cases reporting only mild pain at the last follow-up.
CONCLUSIONS
Based on the surgical findings of our 11 LDH cases with contralateral symptoms, we hypothesized that the contralateral symptoms might be produced when the nerve root on the contralateral symptomatic side was tightly pulled by the herniated disc via the dural mater. Ipsilateral hemilaminectomy and discectomy surgery effectively and efficiently relieve the symptoms without postoperative complications for these patients.

Comparative Study
OBJECTIVE
To evaluate the clinical-surgical results of the tubular vs. mini-open approach in lumbar discoidectomy. The tubular approach promises to reduce the number of rest days and an earlier return to daily activities and work.
METHOD
A case-control study of patients operated on for disc herniation using tubular surgery (case) and mini-open (control) was carried out. The variables investigated were as follow: radicular and lumbar pain, sex, age, failure in conservative treatment, single-level lumbar hernia, surgical time, bleeding, length of hospital stay, persistence of symptoms, complications, occupational activity, and reintegration into everyday activities.
RESULTS
Through 100 surgeries performed, two groups were created, tubular and mini-open, with 50 patients each, with L4-L5 or L5-S1 disc herniation, respectively. The most affected level was L4-L5 (69%). Of the total cases, a significant improvement was found (p < 0.05) at 15 postoperative days in the VAS and ODI scale in the tubular group with respect to mini-open. Complications such as surgical wound infection, durotomy, and persistent pain occurred.
CONCLUSIONS
The tubular approach is a safe and effective option for herniated discs of the lumbar segment, and reduces surgical times, bleeding, and the time of reinsertion to daily activities of the patient.

Meta-Analysis Review
Comparison of outcomes between tubular microdiscectomy and conventional microdiscectomy for lumbar disc herniation: a systematic review and meta-analysis of randomized controlled trials.
PURPOSE
The clinical outcomes of using a tubular microdiscectomy for lumbar disc herniation were evaluated by comparison with conventional microdiscectomy.
METHODS
All of the comparative studies published in the PubMed, Cochrane Library, Medline, Web of Science, and EMBASE databases as of 1 May 2023 were included. All outcomes were analysed using Review Manager 5.4.
RESULTS
This meta-analysis included four randomized controlled studies with a total of 523 patients. The results showed that using tubular microdiscectomy for lumbar disc herniation was more effective than conventional microdiscectomy in improving the Oswestry Disability Index (P < 0.05). However, there were no significant differences in operating time, intraoperative blood loss, hospital stay, Visual Analogue Scale, reoperation rate, postoperative recurrence rate, dural tear incidence, and complications rate (all P > 0.05) between the tubular microdiscectomy and conventional microdiscectomy groups.
CONCLUSIONS
Based on our meta-analysis, it was found that the tubular microdiscectomy group had better outcomes than the conventional microdiscectomy group in terms of Oswestry Disability Index. However, there were no significant differences between the two groups in terms of operating time, intraoperative blood loss, hospital stay, Visual Analogue Scale, reoperation rate, postoperative recurrence rate, dural tear incidence, and complications rate. Current research suggests that tubular microdiscectomy can achieve clinical results similar to those of conventional microdiscectomy. PROSPERO registration number is: CRD42023407995.

This study aims to compare the outcomes of interlaminar and transforaminal approaches for full-endoscopic discectomy (FED) for treating L4/5 lumbar disc herniation (LDH).A retrospective study of patients with L4/5 LDH treated with interlaminar endoscopic lumbar discectomy (IELD, n = 19) or transforaminal endoscopic lumbar discectomy (TELD, n = 105) was conducted. Patient background, radiological findings, and operative data were collected. Oswestry Disability Index (ODI) and European Quality of Life-5 Dimension (EQ-5D) scores were recorded preoperatively and 1 and 2 years postoperatively.Although ODI and EQ-5D scores 1 and 2 years postoperatively improved statistically in the IELD and TELD groups, there were no statistical differences between the groups. IELD was predominantly performed in patients who were taller and heavier. The mean operative times and the frequency of laminectomy for IELD and TELD were 67.2 and 44.6 min and 63.2 and 17.1%, respectively (P < 0.001). The radiological findings showed that the concave configuration of the L4 lamina, interlaminar space width, and foraminal width were statistically different between the groups. There were no complications in either of the groups. Reoperation was required for recurrence in two and five patients in the IELD and TELD groups (P = 0.29), respectively.Operative outcomes were identical between the two groups. Although the operative time was longer in the IELD group, both approaches were safely and effectively performed. Depending on the patient's physique and preoperative radiological findings, the more suitable approach for L4/5 LDH should be chosen.

Cervical conjoined nerve root is rare, and medical imaging, such as magnetic resonance imaging and computed tomography, cannot give an accurate preoperative diagnosis. Treatment of cervical radiculopathy with root anomaly can be challenging. We report here a case of cervical conjoined nerve root with a 2-dimensional video. A 41-year-old woman without systemic disease presented with a 2-month history of neck and bilateral shoulder pain, upper back tightness, and left upper limb painful numbness, especially of the first to third fingers. The visual analog scale scores of the neck and left upper limb were 4 and 8, respectively. The Neck Disability Index was 26. The diagnosis of retrolisthesis at C5-C6 and cervical disk herniation with severe neuroforaminal narrowing at the left C5-C6 and C6-C7 levels were made with radiographs and magnetic resonance imaging. Posterior percutaneous endoscopic cervical diskectomy at the left C5-C6 and C6-C7 levels via an interlaminar shoulder approach was performed. During operation, a left-sided conjoined nerve root at the C6-C7 level was found (Video 1). Upon removal of a calcified disk and osteophytes at the C6-C7 level, the dura was torn slightly with traction without nerve root exposure or cerebrospinal fluid leakage. The 3-month postoperative follow-up visual analog scale scores of the neck and left upper limb were 0 and 0, respectively. The 3-month postoperative follow-up Neck Disability Index was 1. Posterior percutaneous endoscopic cervical diskectomy has become a favored treatment for cervical disk herniation because it offers sufficient decompression, smaller incisions, minimal blood loss, shorter hospital stay, and less postoperative pain. Nonetheless, if unexpected variation of the nerve root is noted during decompressive procedures, iatrogenic nerve root injury is a risk. Seven cases of cervical nerve root anomalies have been reported; all were found during posterior cervical surgery, which may indicate that the posterior approach provides better visualization of nerve root variants, especially in endoscopic surgery..

Meta-Analysis
Comparative efficacy of unilateral biportal endoscopy and micro-endoscopic discectomy in the treatment of degenerative lumbar spinal stenosis: a systematic review and meta-analysis.
BACKGROUND
Given the inconclusive literature on operative time, pain relief, functional outcomes, and complications, this meta-analysis aims to compare the efficacy of Unilateral Biportal Endoscopy (UBE) and Micro-Endoscopic Discectomy (MED) in treating Degenerative Lumbar Spinal Stenosis (DLSS).
METHODS
A thorough literature search was conducted in accordance with the PRISMA guidelines and based on the PICO framework. The study interrogated four primary databases-PubMed, Embase, Web of Science, and the Cochrane Library-on August 16, 2023, without time restrictions. The search employed a strategic selection of keywords and was devoid of language barriers. Studies were included based on strict criteria, such as the diagnosis, surgical intervention types, and specific outcome measures. Quality assessment was performed using the Newcastle-Ottawa Scale, and statistical analysis was executed through Stata version 17.
RESULTS
The meta-analysis incorporated 9 articles out of an initial yield of 1,136 potential studies. Considerable heterogeneity was observed in surgical duration, but no statistically significant difference was identified (MD = - 2.11, P = 0.56). For VAS scores assessing lumbar and leg pain, UBE was statistically superior to MED (MD = - 0.18, P = 0.013; MD = - 0.15, P = 0.006, respectively). ODI scores demonstrated no significant difference between the two surgical methods (MD = - 0.57, P = 0.26). UBE had a lower incidence of complications compared to those receiving MED (OR = 0.54, P = 0.036).
CONCLUSIONS
UBE and MED exhibited comparable surgical durations and disability outcomes as measured by ODI. However, UBE demonstrated superior efficacy in alleviating lumbar and leg pain based on VAS scores. The findings present an intricate evaluation of the two surgical interventions for DLSS, lending valuable insights for clinical decision-making.
