Lumbar disc herniation is one of the most common causes of low back and leg pain in clinic. There are a lot of non-surgical therapeutic methods widely used in clinic for treating lumbar disc herniation. The author assessed the available systematic reviews of non-surgical methods in treating lumbar disc herniation which had been published in these years, and finally a total of 13 systematic reviews were retrieved including 1 about conservative treatments, 8 Chinese medicine treatments, and 4 percutaneous treatments, such as chemonucleolysis and epidural steroid injection. The results showed that the conservative treatments included injections, traction, physical therapy, bed rest, manipulation, medication, and acupuncture. But no evidence was found to show that any of the above treatments was clearly superior to others including no treatment for patients with lumbar disc herniation. The outcomes from some reviews showed that Chinese medicine treatments were safer and comprehensive treatment of traditional Chinese medicine was relatively effective compared with single treatment. Electro-acupuncture, compared with conventional therapy (bed rest, waist protection, pelvic traction, manual or physical therapy) and oral medications as well, was safe and effective in alleviating pain and improving overall function. Chinese medicinal fumigation combined with traction was more effective than single treatment. Percutaneous treatment of chemonucleolysis had much better short-term effectiveness. Percutaneous epidural steroid injection also had certain effects. To summarize, Chinese medicine and percutaneous treatments may be effective in treating lumbar disc herniation. However, more clinical trials are needed, since current evidence is of low quality.
ObjectiveTo evaluate the short-term effectiveness of percutaneous endoscopic lumbar discectomy (PELD) in treatment of buttock pain associated with lumbar disc herniation.MethodsBetween June 2015 and May 2016, 36 patients with buttock pain associated with lumbar disc herniation were treated with PELD. Of 36 cases, 26 were male and 10 were female, aged from 18 to 76 years (mean, 35.6 years). The disease duration ranged from 3 months to 10 years (mean, 14 months). The location of the pain was buttock in 2 cases, buttock and thigh in 6 cases, buttock and the ipsilateral lower extremity in 28 cases. Thirty-four patients had single-level lumbar disc herniation, and the involved segments were L4, 5 in 15 cases and L5, S1 in 19 cases; 2 cases had lumbar disc herniation at both L4, 5 and L5, S1. The preoperative visual analogue scale (VAS) score of buttock pain was 6.1±1.3. VAS score was used to evaluate the degree of buttock pain at 1 month, 3 months, 6 months, and last follow-up postoperatively. The clinical outcome was assessed by the modified MacNab criteria at last follow-up.ResultsAll patients were successfully operated and the operation time was 27-91 minutes (mean, 51 minutes). There was no nerve root injury, dural tear, hematoma formation, or other serious complications. The hospitalization time was 3-8 days (mean, 5.3 days). All incisions healed well and no infection occurred. Patients were followed up 12-24 months (median, 16 months). MRI examination results showed that the dural sac and nerve root compression were sufficiently relieved at 3 months after operation. Patients obtained pain relief after operation. The postoperative VAS scores of buttock pain at 1 month, 3 months, 6 months, and last follow-up were 1.1±0.6, 0.9±0.3, 1.0±0.3, and 0.9±0.4 respectively, showing significant differences when compared with preoperative VAS scores (P<0.05); there was no significant difference in VAS score between the different time points after operation (P>0.05). At last follow-up, according to the modifed MacNab criteria, the results were excellent in 27 cases, good in 9 cases, and fair in 2 cases, and the excellent and good rate was 94.4%.ConclusionPELD can achieve satisfactory short-term results in the treatment of buttock pain associated with lumbar disc herniation and it is a safe and effective minimally invasive surgical technique.
Objective To evaluate the efficacy of posterior approach discectomy with and without fusion in the treatment of lumbar disc herniation. Methods We searched MEDLINE (1950 to June 2007), OVID (1950 to April 2007), PUBMED, the China Biological Medicine Database (1978 to June 2007) and Wanfang Database (1981 to February 2007). We also handsearched several relevant journals for randomized controlled trials (RCTs) and quasi-randomized controlled trials (quasi-RCTs) comparing posterior approach discectomy with and without fusion in the treatment of lumbar disc herniation. The quality of the included trials was assessed. The Cochrane Collaboration’s RevMan 4.2.8 software was used for statistical analysis. Results Nine eligible trials involving 1911 patients were included. The meta-analyses found no statistically significant differences between the two operative procedures in the incidence of postoperative leg pain [RR 0.94, 95%CI (0.69, 1.28)], the proportion of patients requiring re-operation [RR 0.77, 95% CI (0.57, 1.04)], the incidence of post-operative lumbar canal stenosis [RR 1.23, 95%CI (0.26, 5.86)], and the relapse rate at other intervertebral spaces [RR 1.05, 95%CI (0.49, 2.26)] (Pgt;0.05).There is statistically significant differences between the two group in the incidence of peri-operative complications [RR 1.46, 95%CI (1.06, 2.00)]. Discectomy plus fusion was superior to discectomy alone in incidence of postoperative back pain [RR 0.70, 95%CI (0.53, 0.94)], relapse rate at either intervertebral space [RR 0.30, 95%CI (0.18, 0.48)] and at the same intervertebral space [RR 0.12, 95%CI (0.04, 0.37)]. Conclusions Since all the included studies were controlled trials with a great potential for biases, high-quality, large-scale randomized controlled trials are required.
Objective
To investigate the effectiveness of combined Pregabalin and Celecoxib for neuropathic pain after percutaneous endoscopic lumbar discectomy.
Methods
Between January and June 2014, 178 patients with lumbar disc herniation underwent percutaneous endoscopic interlaminar discectomy (PEID). Ninety patients who met the inclusion criteria were recruited in this study. Every case in group A was recruited to match its counterpart in group B and group C according to gender, disease duration, herniated level, smoking history, preoperative Leeds assessment of neuropathic symptoms and signs (LANSS), and Oswestry disability index (ODI). Nine patients were excluded due to incomplete study or loss of follow-up. In each group, 27 cases were included in the final analysis. There was no significant difference in gender, age, height, body mass index, herniated level, disease duration, smoking history, preoperative LANSS, ODI, and visual analogue scale (VAS) between groups (P>0.05). All patients of 3 groups received oral administration of Celecoxib from preoperative 3rd day to postoperative 14th day. Pregabalin was taken orally from preoperative 3rd day to postoperative 14th day in group A, and from postoperative 1st to 14th day in group B. Adverse drug reactions were observed during medication. The LANSS score and VAS score in rest state and active state were conducted before operation and at 1 day, 1 month, and 3 months after operation. ODI was conducted before operation and at 1, 3 months after operation. The number of neuropathic pain cases was recorded, and the effectiveness was evaluated by modified Macnab criteria at 3 months after operation.
Results
During period of increasing Pregabalin dose, 1 patient of group A suffered severe dizziness, and 1 patient of group B suffered sleepiness, who were eliminated from this research. Another 2 cases (1 case of group A and 1 case of group C) suffered dry mouth, and 1 case of group B suffered muscle weakness. At 1 day after operation, the LANSS score and VAS in rest state and active state of group A were significantly lower than those of groups B and C (P<0.05). At 1 month after operation, the LANSS score, ODI, and VAS in rest state and active state of group A and group B were significantly lower than those of group C (P<0.05). At 3 months after operation, the LANSS score, ODI, and VAS in active state of group A and group B were significantly lower than those of group C (P<0.05). There was no significant difference in the above indicators at the other time points between groups (P>0.05). Neuropathic pain occurred at 3 months after operation in 1 case (3.7%) of group A and 6 cases (22.2%) of group C, showing significant differences in incidence of neuropathy pain between groups A, B and group C (P<0.05), but no significant difference was found between group A and group B (P>0.05). The excellent and good rate of modified Macnab criteria was 92.6% in group A, was 88.9% in group B, and was 85.2% in group C at 3 months after operation, showing no significant difference between groups (P>0.05).
Conclusion
Combined use of Pregabalin and Celecoxib during perioperative period can reduce postoperative pain and incidence of postoperative neuropathic pain. Preoperative oral Pregabalin can reduce the incidence of acute postoperative neuropathic pain.
ObjectiveTo compare the early efficacy between Quadrant channel and traditional method in treating lumbar disc herniation.
MethodBetween July 2010 and December 2012, 60 patients with lumbar disc herniation were randomly divided into two groups with 30 in each. Quadrant channel and traditional method were used respectively to do the same one single segmental pedicle screw fixation with single pieces of cage bone grafting fusion and internal fixation. Then, we compared the two groups in incision length, operative time, blood loss, incision healing time and postoperative incidence of low back pain between the two groups of patients.
ResultsThere were no significant differences between the two groups in terms of operation time, blood loss, and recent curative effect (P>0.05), while Quadrant channel was superior in small skin incision, reduced incidence of low back pain, and shorter postoperative incision healing time (P<0.05).
ConclusionsTreatment of lumbar disc herniation using Quadrant channel is minimally invasive with less complications. Mid-and long-term efficacy remains to be further analyzed.
Objective
To explore the postoperative satisfaction of patients with lumbar disc herniation after enhanced recovery after surgery and its related factors.
Methods
A total of 102 patients with lumbar disc herniation were selected and analyzed by convenient sampling method from September 2016 to June 2017. The patients’ general information, functional status [using the Oswestry Disability Index (ODI) to investigate the preoperative, postoperative and post-discharge ODI] and patients’ satisfaction (1 month after the discharge) were collected.
Results
A total of 102 patients, including 62 males and 40 females, aged from 14 to 82 years with an average of (43.8±14.4) years were included in the study.The mean length of hospital stay was (6.61±2.49) days. The total score of patients’ satisfaction was 62.43±6.37, and the satisfaction degree was at the middle and high level. Postoperative and post-discharge ODIs were associated with patients’ satisfaction (rs=0.328, 0.452; P<0.05).
Conclusions
The postoperative satisfaction of patients with lumbar disc herniation after enhanced recovery after surgery should be further improved. The medical staff should pay attention to the recovery of postoperative function in order to improve the patients’ satisfaction.
ObjectiveTo summarize the research progress of resorption of lumbar disc herniation (RLDH). Methods The literature on RLDH at home and abroad in recent years was reviewed to summarize its influencing factors, pathogenesis, imaging findings, and predictive effect, as well as its influence on the treatment selection of lumbar disc herniation (LDH). ResultsThe main mechanism of RLDH is the combined effect of inflammatory response and neovascularization. Age, smoking, body mass index, and clinical manifestations are the influencing factors. Studies have shown that the annular enhancement around the nucleus pulposus on enhanced MRI images is the characteristic imaging manifestation of RLDH, which is a predictor of whether RLDH occurs. In the treatment of LDH, cyclooxygenase 2 inhibitors may have a negative impact on RLDH. ConclusionThe occurrence of RLDH suggests that strict conservative treatment is the first choice for LDH treatment, but surgery is still an important treatment method when the patient’s symptoms and imaging symptoms don’t significantly improved after conservative treatment.
Objective To compare the effectiveness of unilateral biportal endoscopy (UBE) technique with the interlaminar uniportal endoscopy (IUE) technique for the treatment of L5, S1 lumbar disc herniation. MethodsThe clinical data of 69 patients with L5, S1 lumbar disc herniation who met the selection criteria between January 2020 and December 2020 were retrospectively analysed. The patients were divided into UBE group (30 cases) and IUE group (39 cases) according to endoscopic surgical technique. The general data, such as gender, age, body mass index, disease duration, and preoperative visual analogue scale (VAS) scores of low back/leg pain and Oswestry disability index (ODI), was not significantly different between the two groups (P>0.05). Perioperative outcomes [estimated blood loss (EBL), total operation time, extracanal operation time, intracanal decompression time, intraoperative radiation exposure dose, incision length, operative related complications, and postoperative hospitalization stay] and clinical outcomes (VAS score of low back/leg pain before operation and at 3 days, 3 months, 6 months, and 12 months after operation as well as the ODI before operation and at 3 months, 6 months, and 12 months after operation) were recorded and compared between the two groups. ResultsAll patients completed the surgery successfully. The incision length, EBL, and extracanal operation time in UBE group were significantly longer than those in IUE group (P<0.05), and the intracanal decompression time in UBE group was significantly shorter than that in IUE group (P<0.05). There was no significant difference in the total operation time, intraoperative radiation exposure dose, and postoperative hospitalization stay between the two groups (P>0.05). Patients in both groups were followed up 12-15 months (mean, 13.3 months). Dural tear ocurred in 1 patient of the UBE group, and recurrence ocurred in 1 patient of the IUE group, the others of both groups had no surgery-related complications and recovered well after operation. The VAS scores of low back/leg pain and ODI in both groups at each time point after operation significantly improved when compared with those before operation (P<0.05); there was no significant difference in VAS scores and ODI at each time point after operation between two groups (P>0.05). ConclusionThe effectiveness of UBE technique in the treatment of L5, S1 lumbar disc herniation is similar to that of IUE technique, and the efficiency of intraspinal operation is better than that of IUE technique. Although UBE technique is inferior to IUE technique in terms of surgical trauma, there is no significant difference in postoperative recovery between the two techniques.
Objective To investigate diagnosis and treatment of farlateral lumbar disc herniations. Methods The clinical data from 16 patients with far-lateral lumbar disc herniations from January 1999 to January 2004 were retrospectively analyzed. The CT scanning showed that the shadow density of the CT scanning values in the corresponding intra-foramen, extraforamen and all-foramen was as the same as that of the intervertebral disc. Of the 16 patients, 10 were operated on by the interlaminar approach, 3 were operatedon by the laterolaminar approach, 3 were operated on by the combined interlaminal and laterolaminal approach.Results According to the follow-up for 6 monthsto 5 years, excellent results were obtained in 8 patients, good results in 5, and fair results in 3. The postoperative CT examination showed that the space occupying in the foramen or extraforamen of the corresponding segment vanished and the nerve root compression of the identical segment also vanished. Conclusion The lamellar highresolution CT is a better way to diagnose lumbar disc herniation. The operative approach should be chosen according to the position of the intervertebral disc protrusion, pathologic type, and presence or absence of the lesions in the vertebral canal.
ObjectiveTo investigate the feasibil ity and short-term effectiveness of percutaneous endoscopic spine surgery for treatment of lumbar disc herniation with posterior ring apophysis separation.
MethodsBetween July 2008 and January 2013, 57 patients with lumbar disc herniation and posterior ring apophysis separation were treated. There were 39 males and 18 females, aged from 13 to 46 years (mean, 26.7 years). Of 57 cases, 29 had a clear trauma history. All patients had single segmental unilateral lumbar disc herniation, and the location was at L4, 5 in 22 cases and at L5, S1 in 35 cases; there were 25 cases of lateral bone fragments and 32 cases of central cortical and cancellous fragments. While fracture located at posterior inferior edge of the vertebrae at L4 level in 9 cases and at L5 level in 8 cases, at posterior superior edge at L5 level in 13 cases and in S1 level in 27 cases. Percutaneous endoscopic surgeries were performed via interlaminar or transforaminal approach from unilaterally symptomatic side for discectomy of lumbar disc herniation and partial or complete resection of free bone fragments.
ResultsAccurate positioning was obtained in all patients during operation, and no complication of nerve root injury, hematoma formation, or dural tear occurred. The operation time was 20-85 minutes; the intraoperative fluoroscopy times were 2-15 times, and the blood loss was 3-10 mL. Postoperative radiographic examination showed that bone fragment was not removed in 16 cases, was partly removed in 32 cases, and was completely removed in 9 cases. Disc was completely removed. All patients were followed up 10-64 months (median, 16 months). According to modified Macnab criteria for the evaluation of effectiveness, the results were excellent in 48 cases, good in 6 cases, and fair in 3 cases, and the excellent and good rate was 94.7%.
ConclusionPercutaneous endoscopic spine surgery through unilaterally symptomatic approach has advantages of small tissue damage and lumbar structure damage, less bleeding, and shorter recovery time. It has a good short-term effectiveness, but long-term effectiveness need further follow-up.
