Lumbar disc herniation (LDH) is the most common cause of radiculopathy, whose pathological entity underlying nerve root compression is usually on the same side as the symptoms. However, LDH causing contralateral radiculopathy are sometimes encountered by pain physicians. There have been tremendous developmens in the treatment options for LDH; the situation of LDH causing contralateral radiculopathy is indeed a dilemma for some pain physicians. We will report a case of a patient with a L4-5 disc herniation whose left herniated disc caused radiculopathy on the right side. After a percutaneous lumbar endoscopic discectomy via the side ipsilateral to the symptomatic side, this case obtained a significant symptom remission. The migrated epidural fat is discussed as a cause of associated contralateral neurological deficit. Only via a surgical approach ipsilateral to the herniated side, could there be a clinical improvement postoperatively. Key words: Contralateral symptoms, lumbar disc herniation, radiculopathy, epidural fat

Background: Groin pain can be induced by high-level (L1-L2 or L2-L3) lumbar disc herniation. However, 4.1% of patients with lower-level (L4-L5 or L5-S1) lumbar disc herniation also complained of groin pain. The pathomechanism of groin pain occurring due to lumbar disc herniation at and below the L4-5 levels is still unclear. Objective: To investigate the afferent pathways of lower-level lumbar disc herniation induced groin pain. And evaluate the clinical results of transforaminal endoscopic discectomy treatment for discogenic groin pain. Study Design: This retrospective observational study used an experimental design (institutional review board: HROH 201-C2-100). Setting: The research took place in the Laboratory Research Center and spine center at The First Affiliated Hospital of Harbin Medical University. Methods: Firstly, 14 adult Wistar rats were randomly divided into 2 groups: control group (the paravertebral sympathetic trunks were preserved) and experimental group (the paravertebral sympathetic trunks were resected). All Wistar rats were intraperitoneally anesthetized, and then 1 μL of fast blue was injected into the dorsal rami of L2 spinal nerves on the right side. Forty hours later, 2 μL of nuclear yellow was injected into the right posterior portion of the L5-L6 intervertebral disc. The L1 and L2 spinal ganglia were sectioned 8 hours later to observe fluorescently double-labeled cells and the effect of paravertebral sympathetic trunk resection. Secondly, 14 adult Wistar rats were anesthetized, and the right posterior portion of the L5- L6 intervertebral disc was electrostimulated to observe potential changes in the genitocrural nerve in the ipsilateral inguinal region. To evaluate the clinical outcomes of transforaminal endoscopic discectomy for the treatment of discogenic groin pain, between September 2015 and May 2017, transforaminal endoscopic discectomy was performed on 30 patients with lower-level discogenic groin pain. Outcomes were analyzed utilizing the visual analog scale, Oswestry disability index, and MacNab Criteria. Results: The total proportion of cells in the right L1 and L2 spinal ganglia with fast blue/nuclear yellow double labeling was 3.33% and 3.41% (48 and 56), respectively. The number of fluorescently doublelabeled cells in the resected paravertebral sympathetic trunk group was significantly less (P < 0.01). Electrical stimulation of the right posterior portion of the L5-L6 intervertebral disc could elicit action potentials in the ipsilateral genitofemoral nerve. All patients were followed for 12 months, and the visual analog scale score at 1 week, 1 month, 3 months, 6 months, and 12 months after the operation was 0.79 ± 0.55, 0.54 ± 0.55, 0.47 ± 0.65, 0.51 ± 0.65, and 0.69 ± 0.55, respectively, showing a significant decrease compared with the preoperative visual analog scale score (P < 0.01). Based on the MacNab scoring system, the effective rate was 100%, and the rate of good and excellent results was 93.3%. Limitations: A relatively small number of patients and a short follow-up period. Conclusions: Discogenic groin pain is transmitted by sympathetic nerves and appears in the area segmentally innervated by the anterior rami of the L1 and L2 spinal nerves. Posterolateral percutaneous transforaminal endoscopic discectomy and radiofrequency thermal annuloplasty are effective minimally invasive alternative treatments for discogenic groin pain. Key Words: Discogenic groin pain, percutaneous transforaminal endoscopic discectomy, radiofrequency thermal annuloplasty

The anaerobic skin commensalPropionibacterium acnesis an underestimated cause of human infections and clinical conditions. Previous studies have suggested a role for the bacterium in lumbar disc herniation and infection. To further investigate this, five biopsy samples were surgically excised from each of 64 patients with lumbar disc herniation.P. acnesand other bacteria were detected by anaerobic culture, followed by biochemical and PCR-based identification. In total, 24/64 (38%) patients had evidence ofP. acnesin their excised herniated disc tissue. UsingrecAand mAb typing methods, 52% of the isolates were type II (50% of culture-positive patients), while type IA strains accounted for 28% of isolates (42% patients). Type III (11% isolates; 21% patients) and type IB strains (9% isolates; 17% patients) were detected less frequently. The MIC values for all isolates were lowest for amoxicillin, ciprofloxacin, erythromycin, rifampicin, tetracycline, and vancomycin (≤1mg/L). The MIC for fusidic acid was 1-2 mg/L. The MIC for trimethoprim and gentamicin was 2 to ≥4 mg/L. The demonstration that type II and III strains, which are not frequently recovered from skin, predominated within our isolate collection (63%) suggests that the role ofP. acnesin lumbar disc herniation should not be readily dismissed.

Abstract Background: Percutaneous Transforaminal Endoscopic Discectomy is used increasingly in patients with Lumbar Disc Herniation. There is little knowledge on the related factors including SLR test influencing the operation. Therefore, we designed this prospective study to explore the relevant factors influencing postoperative effect of PTED surgery.Methods: Consecutive patients with LDH who came to our hospital from August 2015 to September 2016 and received PTED surgery. 4 kinds of scales including VAS (lumbar/leg), ODI and JOA were measured and reassessed at 1 day, 3 months, 6 months, 12months and 36 months after the PTED to assess their surgical outcomes. Results: All the patients had successful surgery. ODI and VAS (lumbar/leg) decreased in all patients and groups. And there was a statistically significant difference in each postoperative follow-up compared with that before surgery in every visit. In addition, the increase of JOA in postoperation was statistically significant compared with that before surgery. And, there is statistically significant difference between the three subpopulations (patients with SLR Positive (0°-30°), SLR Positive (31°-60°) and SLR Negative (61°-) in the changes of the scores of VAS(leg), ODI and JOA. However, there is no statistically significant difference between the three subpopulations (patients with SLR Positive (0°-30°), SLR Positive (31°-60°) and SLR Negative (61°--RRB- in the changes of the score of VAS(lumbar). Conclusions: PTED showed great effect on treating patients with lumbar disc herniation. And the main scale score such as VAS(leg). ODI and JOA showed that there is a statistically significant difference between the three subpopulations treated by PTED. Patients with SLR negative may get greater benefit from PTED.

Background and objectives: Lumbar disc herniation (LDH) is a common disease in the meridian of life. Although surgical discectomy is commonly used to treat LDH, there are several different strategies. We compared the outcomes of uniportal full-endoscopic discectomy (FED) with those of microendoscopic discectomy (MED) in treating LDH. Materials and Methods: FED was performed using a 4.1-mm working channel endoscope, and MED was performed using a 16-mm diameter tubular retractor and endoscope. Data of patients with LDH treated with FED (n = 39) or MED (n = 27) by the single surgeon were retrospectively reviewed. Patient background information and operative data were collected. Pre- and postoperative low back and leg pain were evaluated using the numerical rating scale (NRS) score. Pre- and postoperative disc height index (DHI) values were calculated from plain radiographs, and the disc height loss was evaluated using the ratio (DHI ratio); Results: The median (interquartile range (IQR) Q25–75) operation times for FED and MED were 42 (33–61) and 43 (33–50) minutes, respectively. The median (IQR Q25–75) pre- and postoperative NRS scores for low back pain were 5 (2–7) and 1 (0–4), respectively, for FED and 6 (3–8) and 1 (0–2), respectively, for MED. The median (IQR Q25–75) pre- and postoperative NRS scores for leg pain were 7 (5–8) and 0 (0–2), respectively, for FED and 6 (5–8) and 0 (0–2), respectively, for MED. These data were not different between the FED and MED groups. The median (IQR Q25–75) DHI ratios of FED and MED were 0.94 (0.89–1.03) and 0.90 (0.79–0.95), respectively. The DHI ratio was significantly higher (p < 0.05) in the FED group than in the MED group, and there was less blood loss; Conclusions: The pain-relieving effect of FED in treating LDH was almost identical to that of MED. However, FED was superior to MED in preventing disc height loss, which is one of the indicators of postoperative disc degeneration.
