Endoscopic Lumbar Discectomy

Background: Conventional percutaneous endoscopic lumbar discectomy (PELD) with an “insideoutside” technique has 4.3% – 10.3% surgical failure rate, especially in central herniated discs (HDs), migrated HDs, and axillary type HDs. PELD with foraminoplasty has been used for complex HDs. Percutaneous lumbar foraminoplasty (PLF), which is performed with a trephine or bone reamer introduced over a guidewire without a protective working cannula in the original Tessys technique, can quickly cut the hypertrophied bony structure under fluoroscopic guidance, and risk injury to the exiting and traversing nerve roots. Study Design: A prospective cohort study. Setting: Hospital and outpatient surgical center. Objective: To evaluate the outcome and safety of modified PLF-PELD with a specially designed instrument for complex uncontained lumbar HDs. Method: From April of 2007 to April of 2009, 148 patients with uncontained lumbar HDs were treated with modified PLF-PELD. Magnetic resonance imaging (MRI) checkup was performed the next morning after the operation. Outcomes of symptoms were evaluated by follow-up interviews at 3 months, 6 months, one year, and 5 years after surgery. Low back pain and leg pain were measured by visual analog scale (VAS) score (1 – 100). Functional outcomes were assessed by using the Oswestry Disability Index (ODI) and modified MacNab criteria. Result: Follow-up data were obtained from 134 cases, including 14 cases on L3-4, 78 cases on L4-5, and 42 cases on L5-S1. One hundred-eight cases were prolapse type, while 26 cases were sequestration type. Pre-operative symptoms and deficits included nerve root dermatome hypoesthesia in 98 patients (73%), nerve root myotome muscle weakness in 32 patients (23%), and weakening or disappearance of tendon reflex in 43 patients (32%). No case required conversion to an open procedure during the surgery. Low back pain and leg pain were significantly relieved immediately after surgery in all patients. MRI examination showed adequate removal of HD in all patients. VAS scores and ODI values were significantly lower at all time points after surgery than before surgery. The percentage of pain relief in leg pain was significantly higher than that in low back pain (P < 0.01). But there was no significant correlation between duration of the preoperative symptoms and the percentage of pain relief. MacNab scores at 5 years after surgery were obtained from 134 patients. Seventy-five cases were rated “excellent”; 49 were rated “good,” Five patients experienced heavier low back pain, thus being classified as “fair.” Five cases with recurrence were rated “poor.” Preoperative and postoperative (5 years follow-up) related nerve root function status was compared. Sensation and muscle strength recovered significantly (P < 0.01), while tendon reflex was not changed (P = 0.782). No patients had infections. Five patients were complicated with dysesthesia in distribution of the exiting nerve that was all operated at L5-S1. Complaints were reduced one week after treatment with medium frequency pulse electrotherapy. Five cases required a revision surgery after recurrence. Limitations: This is an observational clinical case series study without comparison.

Abstract Background Effective, inexpensive, and low-risk interventions are needed for patients with nonspecific persistent low back pain (NS-PLBP) who are unresponsive to primary care interventions. Cognitive functional therapy (CFT) is a multidimensional behavioral self-management approach that has demonstrated promising results in primary care and has not been tested in secondary care. Objective To investigate the effect of CFT and compare it with usual care for patients with NS-PLBP. Design Case–control study. Setting A secondary care spine center. Subjects Thirty-nine patients received a CFT intervention and were matched using propensity scoring to 185 control patients receiving usual care. Methods The primary outcome was Roland Morris Disability Questionnaire (0–100 scale) score. Group-level differences at six- and 12-month follow-up were estimated using mixed-effects linear regression. Results At six-month follow-up, a statistically significant and clinically relevant difference in disability favored the CFT group (–20.7, 95% confidence interval [CI] = –27.2 to –14.2, P &lt; 0.001). Significant differences also occurred for LBP and leg pain, fear, anxiety, and catastrophizing in favor of CFT. At 12-month follow-up, the difference in disability was smaller and no longer statistically significant (–8.1, 95% CI = –17.4 to 1.2, P = 0.086). Differences in leg pain intensity and fear remained significantly in favor of CFT. Treatment satisfaction was significantly higher in the CFT group at six- (93% vs 66%) and 12-month (84% vs 52%) follow-up. Conclusions These findings support that CFT is beneficial for patients with NS-PLBP who are unresponsive to primary care interventions. Subsequent randomized controlled trials could incorporate booster sessions, which may result in larger effects at 12-month follow-up.

Abstract Background In recent decades, endoscopic techniques to treat lumbar disc herniation (LDH) have gained popularity in clinical practice. However, there is little literature on the use of percutaneous endoscopic lumbar discectomy (PELD) to treat cauda equina syndrome (CES) due to LDH. This study aims to evaluate the feasibility and clinical efficacy of PELD for treating CES caused by disc herniation, and as well as to report some technical strategies. Methods Between October 2012 and April 2018, 15 patients with CES caused by LDH at the early and intermediate stages of Shi’s classification were selected as the subjects of study, and underwent PELD. All patients were followed up for at least two years. The patients’ back pain and leg pain were evaluated using visual analogue scale (VAS) scores and the Oswestry Disability Index (ODI). Patient satisfaction was evaluated using the MacNab outcome scale. Clinical outcomes were measured preoperatively and at 3 days, 3 months, 6 months and the last follow-up. Results The VAS score for back pain, leg pain and ODI score significantly decreased from preoperatively scores of 6.67 ± 1.05, 7.13 ± 1.19 and 62.0 ± 6.85 respectively, to postoperatively cores of 1.80 ± 0.41, 1.47 ± 0.52 and 12.93 ± 1.03 at the last follow-up postoperatively. These postoperative scores were all significantly different compared with preoperative scores (P < 0.01). According to the modified MacNab outcome scale, 86.67% of these patients had excellent and good outcomes at the final follow-up. Complications included one patient with cerebrospinal fluid leakage and one patient who developed recurrent herniation; the latter patient finally achieved satisfactory results after reoperation. Conclusion PELD could be used as an alternative surgical method for the treatment of CES due to LDH in properly selected cases and appropriate patient selection. However, the operator should pay attention to foraminoplasty to enlarge the working space.

Objective. To investigate the short- and long-term effects of electroacupuncture (EA) compared with medium-frequency electrotherapy (MFE) on chronic discogenic sciatica.Methods. One hundred participants were randomized into two groups to receive EA (n=50) or MFE (n=50) for 4 weeks. A 28-week follow-up of the two groups was performed. The primary outcome measure was the average leg pain intensity. The secondary outcome measures were the low back pain intensity, Oswestry Disability Index (ODI), patient global impression (PGI), drug use frequency, and EA acceptance.Results. The mean changes in the average leg pain numerical rating scale (NRS) scores were 2.30 (1.86–2.57) and 1.06 (0.62–1.51) in the EA and MFE groups at week 4, respectively. The difference was significant (P<0.001). The long-term follow-up resulted in significant differences. The average leg pain NRS scores decreased by 2.12 (1.70–2.53) and 0.36 (−0.05–0.78) from baseline in the EA and MFE groups, respectively, at week 28. However, low back pain intensity and PGI did not differ significantly at week 4. No serious adverse events occurred.Conclusions. EA showed greater short-term and long-term benefits for chronic discogenic sciatica than MFE, and the effect of EA was superior to that of MFE. The study findings warrant verification. This trial was registered under identifierChiCTR-IPR-15006370.

BackgroundTherapeutic selective nerve root blocks (SNRBs) are a common intervention for patients with sciatica. Patients often are referred to physical therapy after SNRBs, although the effectiveness of this intervention sequence has not been investigated.ObjectiveThis study was a preliminary investigation of the effectiveness of SNRBs, with or without subsequent physical therapy, in people with low back pain and sciatica.DesignThis investigation was a pilot randomized controlled clinical trial.SettingThe settings were spine specialty and physical therapy clinics.ParticipantsForty-four participants (64% men; mean age=38.5 years, SD=11.6 years) with low back pain, with clinical and imaging findings consistent with lumbar disk herniation, and scheduled to receive SNRBs participated in the study. They were randomly assigned to receive either 4 weeks of physical therapy (SNRB+PT group) or no physical therapy (SNRB alone [SNRB group]) after the injections.InterventionAll participants received at least 1 SNRB; 28 participants (64%) received multiple injections. Participants in the SNRB+PT group attended an average of 6.0 physical therapy sessions over an average of 23.9 days.MeasurementsOutcomes were assessed at baseline, 8 weeks, and 6 months with the Low Back Pain Disability Questionnaire, a numeric pain rating scale, and the Global Rating of Change.ResultsSignificant reductions in pain and disability occurred over time in both groups, with no differences between groups at either follow-up for any outcome. Nine participants (5 in the SNRB group and 4 in the SNRB+PT group) underwent surgery during the follow-up period.LimitationsThe limitations of this study were a relatively short-term follow-up period and a small sample size.ConclusionsA physical therapy intervention after SNRBs did not result in additional reductions in pain and disability or perceived improvements in participants with low back pain and sciatica.

Abstract Background: The objective of the retrospective study was to investigated the incidence and risk factors of low back pain (LBP) in patients with lumbar degenerative disease after single-level oblique lateral interbody fusion(OLIF).Methods: In this retrospective study, 120 patients who undergoing single-level OLIF to treat lumbar degenerative disease were recruited. Preoperative and postoperative radiographic parameters, including segmental lordosis(SL), lumbar lordosis(LL), disk height(DH), pelvic incidence(PI), pelvic tilt (PT), sacral slope(SS), thoracic kyphosis(TK), C7-sagittal vertical axis (SVA). Visual analog scale(VAS) for back and leg pain, and Oswestry Disability Index(ODI), were used to evaluate symptoms and quantify disability. All patients achieved at least two-year follow-up.Results: A total of 120 Patients who complained low back pain were apportioned to LBP group (n=38; VAS scores for back pain≥3) or Non-LBP group (n=82;VAS scores for back pain＜3). There was no difference in age(P=0.082), gender(P=0.425), body mass index(P=0.138), degenerative spondylolisthesis or lumbar spinal stenosis(P=0.529) surgical level(P=0.651), blood Loss (P=0.889) and operative time(P=0.731) between the groups. In both groups, the ODI and VAS scores for back pain and leg pain were significantly improved at the final follow-up compared to the preoperative scores (P=0.003). Furthermore, except for the LBP (P=0.000), there were no significant differences in these scores between the two groups at the final follow-up (P > 0.05). According to the radiographic parameters, in Non-LBP group, the LL, SL, DH, TK and SS had all significantly improved; PT and C7-SVA significantly decreased at the final follow-up compared to the preoperative values. The DH in both groups had significantly improved, no significant difference was found(P=0.325). In the final follow-up, LL, PI-LL, PT and C7-SVA in Non-LBP group had more improvements compared to the LBP group (P＜0.05) . Multivariate analysis showed that PT, PI-LL and C7-SVA were identified as significant risk factors for LBP after OLIF.Conclusion: The clinical outcomes of OLIF for single-level lumbar degenerative disease were satisfactory. Our findings showed that PT, PI-LL mismatch and C7-SVA had the greatest impact on the incidence of LBP. Therefore, patients with appropriate decreased PT, improved C7-SVA and PI-LL match experienced less low back pain.

Background: Remarkable advancements in endoscopic spinal surgery have led to successful outcomes comparable to those of conventional open surgery. Large lumbar disc herniation (LLDH) is a serious condition, resulting in higher surgical failure when accessing the herniated disc. Objectives: This study compared the outcomes of LLDH treated with percutaneous endoscopic lumbar discectomy (PELD) and open lumbar microdiscectomy (OLM). Study Design: Retrospective assessment. Methods: This retrospective observational study was conducted from January 2011 to June 2012. Forty-four consecutive patients diagnosed with LLDH without cauda equina syndrome who were scheduled to undergo spinal surgery were included. LLDH was defined as herniated disc fragment occupying > 50% of the spinal canal. Clinical outcomes were evaluated using a visual analogue scale (VAS, 0 – 10), functional status was assessed using the Oswestry Disability Index (ODI, 0 – 100%) at 1, 6, and 24 months postoperatively and surgical satisfaction rate (0 – 100%) at final follow up. Radiological variables were assessed by plain radiography. Results: Forty-three patients were included; 20 and 23 patients underwent PELD and OLM, respectively. Both groups exhibited significant improvements in leg and back pain postoperatively (P < 0.001). Although there was no significant difference in leg pain improvement between the groups, improvement in back pain was significantly higher in the PELD group than in the OLM group (4.9 ± 1.5 vs. 2.5 ± 1.0, P < 0.001). The surgical satisfaction rate of the PELD group was significantly higher than that of the OLM group (91.3% ± 6.5 vs. 84.3% ± 5.2, P < 0.001). Mean operating time, hospital stay, and time until return to work were significantly shorter in the PELD group than in the OLM group (67.8 vs. 136.7 minutes, 1.5 vs. 7.2 days, and 4.2 vs. 8.6 weeks; P < 0.001). Disc height (%) decreased significantly from 23.7 ± 3.3 to 19.1 ± 3.7 after OLM (P < 0.001), but did not change significantly after PELD (23.6 ± 3.2 to 23.4 ± 4.2; P = 0.703). The segmental angle of the operated level increased from 10.3° to 15.4° in the PELD group, which was significantly higher than that in the OLM group (9.6° to 11.6°; P = 0.038). In the OLM group, there was one case of fusion due to instability. In the PELD group, one case required revision surgery and another case experienced recurrence. There were no perioperative complications in either group. Limitation: The study was retrospective with a small sample size and short follow-up period. Conclusion: PELD can be an effective treatment for LLDH, and it is associated with potential advantages, including a rapid recovery, improvements in back pain, and disc height preservation.

Abstract Background: To assess the efficacy of the superior notch of inferior vertebral pedicle approach of transforaminal percutaneous endoscopic lumbar discectomy for very high-grade inferiorly migrated disc herniation.Methods: Data on 32 consecutive patients operated with percutaneous endoscopic surgery via the superior notch of inferior vertebral pedicle approach were reviewed. Age, gender, clinical diagnoses, operation time, hospitalization time, a self-administered questionnaire composed of the leg pain visual analogue scale (VAS leg pain) and the Oswestry Disability Index (ODI) had been recorded before operation and 1, 3, 6 and 12 months after operation, respectively. The clinical results were assessed at the final follow-up by using modified Macnab criteria. Complications were recorded during follow-up, and postoperative X-ray, CT and MRI examinations were performed.Results: There were 21 males and 11 females. The mean age of patients was 51.8±10.6 years. MRI findings of patients with disc herniation were L2-3 level in 4 case, L3-4 level in 9 cases and L4-5 level in 19 cases, which were correlated with clinical symptoms. All patients completed a 12-month follow-up assessment after surgery. The mean operative duration was 68.2±12.8 min, and hospitalization time was 3.6±0.8 days. At 12 months follow up the VAS leg pain had improved by 6.3 (P< 0.05) and the ODI by 43.6 points (P< 0.05). Twenty-three cases (71.9%) were rated as excellent, 7 (21.9%) as good, 2 (6.2%) as fair at the final follow-up. On the basis of the modified MacNab criteria, the overall excellent and good rate was 93.8%. Two patients (6.2%) had transient dysesthesia after surgery. Postoperative radiological evaluations showed no signs of instability or recurrence of pathology.Conclusion: Transforaminal percutaneous endoscopic lumbar discectomy via the superior notch of inferior vertebral pedicle approach could be a safe and effective minimally invasive technique for very high-grade inferiorly migrated disc herniation. This technique warrants further study and clinical application.
