Purpose: To investigate the association of facet joint asymmetry with lumbar disc herniation at the lower lumbar spine. Methods: A total of 90 patients (ages 18–40 years) with single-level disc herniation (L3–L4, L4–L5, or L5–S1) were included in the study. Facet asymmetry was defined as a difference of 10° in facet joint angles between right and left sides. Normal discs in the same segment of other individuals were used as a control. Patients had facet asymmetry measured for L3 to S1 through 3.0T magnetic resonance imaging, and information was collected, including age, sex, degenerative degree of lumbar facet joints, and the presence or absence of lumbar disc herniation and type. Results: At the L3 to L4 level, 2 cases had facet asymmetry in 8 patients with lumbar disc herniation, compared with 17 cases of facet asymmetry in 82 patients without disc herniation (P = 0.7776, r = 0.030). At the L4 to L5 level, there were 21 cases of facet asymmetry in 45 patients with lumbar disc herniation, compared with 5 cases of asymmetry in 45 patients without disc herniation (P = 0.00019, r = 0.392). At the L5 to S1 level, there were 25 cases of facet asymmetry in 37 patients with lumbar disc herniation, compared with 11 cases of facet asymmetry in 53 patients without disc herniation (P = 0.0000, r = 0.492). There were 23 cases of facet asymmetry in 28 disc herniations of side type compared with 2 cases of facet asymmetry in 9 herniations of center type (P = 0.0008, r = 0.364). There was no significant difference in the relationship between age, facet joint degeneration, and lumbar facet joint asymmetry (P > 0.05). Conclusion: Facet asymmetry is significantly associated with lumbar disc herniation at the L4 to L5 and the L5 to S1 levels, whereas there is an obvious association with the side type of lumbar disc herniation at the L5 to S1 level.

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.

Abstract BACKGROUND Endoscopic spine surgery is an alternative to the traditional treatment of lumbar disc herniation. However, the traditional technique of interlaminar endoscopic approach is challenging and risky in patients with concomitant spinal stenosis. OBJECTIVE To report a modified technique called hybrid interlaminar endoscopic lumbar decompression as an effective treatment. METHODS Patients with combined lumbar disc herniation and lateral recess stenosis undergoing full-endoscopic interlaminar lumbar discectomy were retrospectively studied. The hybrid interlaminar endoscopic discectomy technique, as well as the use of 2 endoscopes with different diameters, is described in detail. The large endoscope is used for the laminotomy procedure, while the small endoscope is used for the discectomy procedure. The demographics and clinical outcomes of the patients are presented. RESULTS A total of 19 patients were included in this study. The mean age was 46.7 yr. The visual analog scale for back and leg pain improved from 5.6 ± 3.4 and 7.5 ± 2.3 to 1.8 ± 1.3 and 1.8 ± 1.6, respectively (P < .001). The mean Oswestry Disability Index improved from 59.9 ± 21.2 preoperatively to 18.2 ± 8.5 postoperatively (P < .001). The follow-up was 8.2 mo on average. No major complications occurred, but 2 patients reported mild postoperative paresthesia. One patient had an early recurrence and underwent repeat endoscopic discectomy. CONCLUSION Full-endoscopic lumbar discectomy provides excellent access to the intracanalicular herniation site of an intervertebral disc. By using the endoscopic technique presented here, surgeons can safely and efficiently achieve adequate decompression in patients with lumbar disc herniation combined with spinal stenosis.

OBJECTIVE Although minimally invasive spinal surgery has recently gained popularity, few nationwide studies have compared the adverse events that occur during endoscopic versus open spinal surgery. The purpose of this study was to compare perioperative complications associated with microendoscopic discectomy (MED) and open discectomy for patients with lumbar disc herniation. METHODS The authors retrospectively extracted from the Diagnosis Procedure Combination database, a national inpatient database in Japan, data for patients admitted between July 2010 and March 2013. Patients who underwent lumbar discectomy without fusion surgery were included in the analysis, and those with an urgent admission were excluded. The authors examined patient age, sex, Charlson Comorbidity Index, body mass index, smoking status, blood transfusion, duration of anesthesia, type of hospital, and hospital volume (number of patients undergoing discectomy at each hospital). One-to-one propensity score matching between the MED and open discectomy groups was performed to compare the proportions of in-hospital deaths, surgical site infections (SSIs), and major complications, including stroke, acute coronary events, pulmonary embolism, respiratory complications, urinary tract infection, and sepsis. The authors also compared the hospital length of stay between the 2 groups. RESULTS A total of 26,612 patients were identified in the database. The mean age was 49.6 years (SD 17.7 years). Among all patients, 17,406 (65.4%) were male and 6422 (24.1%) underwent MED. A propensity score–matched analysis with 6040 pairs of patients showed significant decreases in the occurrence of major complications (0.8% vs 1.3%, p = 0.01) and SSI (0.1% vs 0.2%, p = 0.02) in patients treated with MED compared with those who underwent open discectomy. Overall, MED was associated with significantly lower risks of major complications (OR 0.62, 95% CI 0.43–0.89, p = 0.01) and SSI (OR 0.29, 95% CI 0.09–0.87, p = 0.03) than open discectomy. There was a significant difference in length of hospital stay (11 vs 15 days, p < 0.001) between the groups. There was no significant difference in in-hospital mortality between MED and open discectomy. CONCLUSIONS The microendoscopic technique was associated with lower risks for SSI and major complications following discectomy in patients with lumbar disc herniation.

Abstract Background To compare the clinical outcomes of transforaminal lumbar interbody fusion (TLIF) and endoscopic discectomy in the treatment of postoperative adjacent segment degeneration in patients with lumbar disc herniation. Methods From 2014 to 2017, 87 patients who were diagnosed with single-level lumbar disc herniation (LDH) and received surgery of TLIF (group X, n = 43) or endoscopic discectomy (group F, n = 44) were retrospectively analyzed. X-ray, MRI, CT and clinical symptoms were recorded before operation and at the last follow-up. The neurological function was originally evaluated by the (JOA) score of the Japanese Orthopaedic Association. Radiological evaluation included the height of intervertebral space (HIS), intervertebral foramen height (FH), intervertebral foramen area (FA), lumbar lordosis (CA) and intervertebral disc degeneration pfirrmann score.Results There was no significant difference in average operation age, JOA improvement rate, reoperation rate and complications between the two groups. The average blood loss, average hospital stays and average operation time in group F were lower than those in group X. During the last follow-up, HIS, CA and FA decreased in both groups, and the changes in group X were more significant than those in group X (P < 0.05). There was no significant difference in postoperative FH between the two groups, but it decreased more in group X (P < 0.05).Conclusion Both TLIF and endoscopic surgery can achieve good results in the treatment of LDH, but the risk of lumbar adjacent segment degeneration after intervertebral foraminal surgery is lower.

OBJECTIVEAlthough endoscopic procedures for lumbar disc herniation have improved greatly and offer many advantages, the indications are limited mostly to nonmigrated or low-grade migrated disc herniation. Endoscopic application in migrated disc herniation cases is still challenging and technically demanding. The goal in this study was to determine the feasibility of biportal endoscopic discectomy for removal of high-grade migrated disc herniation.METHODSA retrospective review was performed in 262 patients who had undergone biportal endoscopic discectomy after the diagnosis of lumbar herniated disc. According to preoperative MRI findings, disc herniation was classified into 5 zones based on the direction and distance from the disc space. Patients were divided into 2 groups—a high-grade migration group and a low-grade migration group. Clinical outcomes were evaluated using the Oswestry Disability Index (ODI), visual analog scale (VAS), and modified Macnab criteria, and those outcomes and operation time were compared between the 2 groups.RESULTSThere were 10 patients with “high-grade up,” 8 with “low-grade up,” 98 with disc-level, 102 with “low-grade down,” and 44 with “high-grade down” herniation, thereby yielding 54 patients in the high-grade group and 208 in the low-grade group. Demographic data for the 2 groups showed no significant difference. There was no significant difference between the 2 groups in ODI, VAS, and modified Macnab criteria. Operation time between the 2 groups was not significantly different (60.74 vs 65.63 minutes, p > 0.05).CONCLUSIONSBiportal endoscopic discectomy can be effective for high-grade migrated lumbar disc herniation with no prolonged operation time and satisfactory clinical outcomes.

Background: Percutaneous endoscopic interlaminar discectomy (PEID), which poses advantages for certain types of herniated disc, is gaining wider acceptance in clinical practice. We retrospectively analyzed the efficacy of the PEID technique in treatment of calcified lumbar disc herniation. Study Design: A retrospective case-control study. Setting: University hospital in China. Objective: To evaluate the efficacy of the PEID technique in treatment of calcified lumbar disc herniation, and a comparison between calcified and noncalcified disc herniation was drawn to analyze the causes of herniated disc calcification. Methods: Data from patients who underwent full-endoscopic lumbar discectomy in our department between March 2011 and May 2013 were collected. Thirty cases with calcified lumbar disc herniation were included in the study group, and 30 age-, gender-, and body mass index (BMI)-matched cases with noncalcified lumbar disc herniation served as controls. Perioperative data, preoperative and postoperative Visual Analog Scale (VAS) scores, Oswestry Disability Index (ODI) values, MacNab scores, and postoperative low-extremity dysesthesia among patients in the 2 groups were collected. Results: The values of computed tomography (CT) in the calcified group were significantly higher than those in the noncalcified group (P < 0.01). The preoperative disease courses in the 2 groups were similar. However, there was a statistically significant difference in the duration of traditional Chinese medicines (TCM) administration (P < 0.01). VAS and ODI scores improved significantly after surgery, but there were no significant differences between the 2 groups (P > 0.05). Three months after surgery, the rate of low-extremity dysesthesia in the calcified group was significantly higher than that in the control group (P = 0.03) but became similar at 6 months. By applying MacNab criteria the proportions of good and excellent were greater than 90% in both groups, and there was no difference between groups (P > 0.05). Limitations: The sample size was small in this retrospective study. Conclusion: The PEID technique is an effective method in the treatment of calcified lumber disc herniation, although the rate of postoperative dysesthesia is higher in this group during the early postoperative period. Long-term TCM administration may be related to the calcification of herniated lumbar discs. Key words: Lumbar disc herniation, percutaneous endoscopic lumbar discectomy, interlaminar approach, calcification

Background. Both transforaminal percutaneous endoscopic lumbar discectomy with foraminoplasty (TF PELF) and transforaminal percutaneous endoscopic lumbar discectomy without foraminoplasty (TF PELD) were developed for lumbar disc herniation (LDH) patients. However, the safety and effectiveness between the TF PELF and TF PELD have not been investigated. Methods. Of the included 140 LDH patients, 62 patients received TF PELF (PELF group) and 78 patients received TF PELD (PELD group). The operation time, the duration of staying at the hospital, and complication incidences were recorded. All patients were followed up for 2 years, where low back and leg visual analogue scale (VAS) pain ratings and Oswestry Disability Index (ODI) were compared between the 2 groups before and after surgery. Modified Macnab criterion was estimated for all patients at postoperative 2 years. Results. There were no significant difference of the operation time, number of days staying at the hospital, and the incidence of complications between the 2 groups (P>0.05). Two cases in the PELF group and 1 case in the PELD group received a second surgery due to unrelieved symptoms postoperatively. Low back and leg VAS and ODI scores decreased in both groups after operation (P<0.01), respectively, but were not significant between the 2 groups over time (P>0.05). Six patients in the PELF group and 3 patients in the PELD group did not continue the follow-up; thus, only 131 patients completed Macnab evaluation. The satisfactory rate was reported as 80.4% in the PELF group and 90.7% in the PELD group (P>0.05). Conclusions. This study suggested that the safety and effectiveness of TF PELF are comparable to TF PELD for LDH patients.

Percutaneous transforaminal endoscopic discectomy (PTED) is an alternative minimally invasive technique for the treatment of lumbosacral radicular syndrome resulting from lumbar disc herniation. The latter is performed with the help of local anesthesia and sedation in an awake patient with the advantage of direct feedback. Access to the target is lateral and follows a safe trajectory through the Kambin triangle. The main advantages of this surgical technique are the possibility of early discharge within 2 hours after its completion, negligible blood loss, lower risk of infectious complications, convenience in patients with obesity, reduced risk of epidural fibrosis. There are currently no large randomized trials of good quality demonstrating the advantage of PTED over open interlaminar access established in practice. In the worst case, endoscopic discectomy is not known to pose additional risks to patients. The operative technique with a clinical case and a discussion about the applicability of the new approach for the treatment of lumbar disc herniations are presented.
