Objective: To compare the efficacy of the transforaminal approach (TFA) versus the interlaminar approach (ILA) for CT-guided epidural steroid injection (CTESI) in the treatment of persistent lumbosacral radicular pain (LRP > 6 weeks) with long-term follow-up., Methods: Patients were prospectively assessed for pain by visual analogue scale (VAS) and functional disability (Oswestry Disability Index, (ODI)) before treatment, then 6 weeks (6W), 6 months (6 M), and 5 years (5Y) after CTESI., Results: Overall, n = 237 patients (TFA, n = 71 and ILA, n = 166) were included, and 96 patients had 5 years of follow-up. Both groups showed a statistically significant improvement in VAS and ODI values at 6W (TFA, n = 60 and ILA, n = 146, P < 0.001 for both), at 6 M (TFA, n = 34 and ILA, n = 96, P < 0.001 for both), and at 5Y (TFA, n = 32 and ILA, n = 64, P < 0.001 for both). No significant differences were observed between the two approaches in VAS or ODI decreases at 6W (P = 0.38 and P = 0.33 respectively), 6 M (P = 0.13 and P = 0.51 respectively), or 5Y (P = 0.15 and P = 0.57 respectively). No major complications were noted., Conclusion: Outcomes after CTESI by ILA approaches are similar to those by TFA for the treatment of persistent LRP., (© 2023.

Objective: The aim of this study was to invastigate the effect of the sacralization on the results of transforaminal epidural steroid injection for radicular low back pain., Materials and Methods: The study included 64 patients diagnosed with radicular low back pain due to unilateral and single-level lumbar disk herniation. Patients were divided into 2 groups: patients with sacralization (Group S) and patients without lumbosacral transitional vertebrae (Group A). Injection was applied to the relevant level. Patients were evaluated with Numeric Rating Scale and Modified Oswestry Disability Index before, at week 3 and month 3 after the procedure. Sacralization presence was determined by MRI. Sacralization was categorized by anteroposterior lumbar radiography using Castellvi classification. Treatment success was considered as ≥ 50% reduction in NRS scores., Results: Numeric Rating Scale and Modified Oswestry Disability Index scores decreased in both groups on both week 3 and month 3 (p < 0.05). Pain scores of Group S (median value 5 (3-6)) were significantly higher than Group A ((median value 3 (0-5)) in the third month follow-up (p = 0.026), but no significant difference was observed at other time points. There was no significant difference in Modified Oswestry Disability Index scores between the groups at all follow-ups (p > 0.05). Treatment success in the third month was 44.8% in Group S and 65.6% in Group A., Conclusion: Transforaminal epidural steroid injection is an effective and safe method for radicular low back pain. Sacralization presence should be evaluated before treatment considering that it may be a risk factor reducing treatment success., (© 2022.

Introduction: There are no formal guidelines for whether CT-guided or fluoroscopy-guided TFESI should be undertaken for patients with symptoms of lumbar nerve root irritation and corresponding nerve impingement. Here, we sought to compare the efficacy, safety and cost of computer tomography (CT)-guided and fluoroscopically guided transforaminal epidural steroid injection (TFESI)., Materials and Methods: All patients who underwent lumbar TFESI at our institution between June 2016 and June 2018 were identified. Six-week follow-up outcomes were categorised. The radiation doses and associated cost was retrieved from our institution's costing system., Results: One hundred and sixteen patients were included (CT-50; fluoroscopy-56). There were no complications. More patients were discharged 6 weeks after CT-guided lumbar TFESI when compared with fluoroscopically guided TFESI (CT-23, fluoroscopy-14 (P = 0.027)). There was no difference in the number of patients who were referred to surgery (P = 0.18), for further pain management (P = 0.45), or for further TFESI (P = 0.43). The effective radiation dose was significantly higher for CT-guided TFESI (CT-5.73 mSv (3.87 to 7.76); fluoroscopy-0.55 mSv (0.11 to 1.4) (P < 0.01)). The total cost for CT-guided lumbar TFESI was £237.50 (£235 to £337), over £800 less than under fluoroscopic guidance (£1052 (£892.80 to £1298.00), P < 0.01)). Removing cost associated with staff and theatre use (staffing, theatre, medical indemnity and overheads) revealed CT-guided lumbar TFESI to be less expensive than if the procedure was fluoroscopy-guided-CT-guided: £132.6 (130.8 to 197.5); fluoroscopy: £237.4 (£209.2 to £271.9) (P = 0.019)., Conclusions: CT-guided TFESI was associated with a higher discharge rate, a lower cost, but a ten times higher radiation dose when compared with fluoroscopically guided TFESI. Prospective studies are required to compare the efficacy of these procedures and to investigate how the radiation dose of CT-guided TFESI can be reduced without jeopardising efficacy or safety., (© 2022.

Objective: To assess the predictive value of immediate pain-relief after CT-guided transforaminal epidural steroid injection (TFESI) including local anesthetics for longer-term pain relief and patients' global impression of change (PGIC) after 4 weeks., Materials and Methods: One hundred ninety-three patients (age 55.4 ± 14.9) with single-level discogenic lumbar radiculopathy and subsequent TFESI were included. Pain scores were recorded before (NRS 0 ), 15 min (NRS 15min ), and 4 weeks (NRS 4w ) after treatment using a numerical-rating-scale (NRS; 0, no pain; 10, intolerable pain). Additionally, the PGIC was assessed after 4 weeks. Two fellowship-trained musculoskeletal radiologists evaluated nerve compression of the injected level and contrast dispersion. Spearman's rank and point-biserial correlation were applied to assess associations between outcome variables and demographics/imaging findings. A p-value < 0.05 was considered to be statistically significant., Results: There was a significant positive correlation between immediate pain-relief and longer-term pain-reduction (r = 0.24, p = 0.001) with an odds ratio of 2.0 (CI: 1.1-3.6). A good short-term response (NRS 15min  ≥ 50% reduction) was associated with a persistent longer-term good response (NRS 4w  ≥ 50% reduction) in 59.7% (CI: 50.9-68.0%) of patients. There was no association between short-term pain-relief and PGIC after 4 weeks (p = 0.18). Extent and location of nerve compression and contrast dispersion during TFESI did not correlate with longer-term pain-relief (all p ≥ 0.07)., Conclusion: Our results indicate a significant positive correlation between immediate post-procedural and longer-term pain relief after TFESI in patients with lumbar radiculopathy; however, no effect of short-term pain relief is seen on PGIC after 4 weeks. Patients with good longer-term outcome (≥ 50% pain reduction) are twice as likely to have already shown good immediate pain reduction after TFESI., (© 2022. The Author(s).)

Objective: To investigate the impact of contrast dispersion pattern/location during lumbar CT-guided transforaminal epidural steroid injection (TFESI) and experience of the performing radiologist on therapeutic outcome., Materials and Methods: In this single-center retrospective cohort study, two observers analyzed contrast dispersion during CT-guided TFESI of 204 patients (age 61.1 ± 14 years) with discogenic unilateral single-level L4 or L5 radiculopathy. The contrast dispersion pattern was classified as "focal," "linear," or "tram-track"; the location was divided into "extraforaminal," "foraminal," or "recessal." Pain was assessed before and 4 weeks after treatment using a numerical rating scale (0, no pain; 10, intolerable pain). Additionally, the patient global impression of change (PGIC) was assessed. The TFESI was performed by musculoskeletal radiologists (experience range: first year of musculoskeletal fellowship training to 19 years). Contrast pattern/location and radiologist's experience were compared between "good responder" (≥ 50% pain reduction) and "poor responder" (< 50%). A p-value < 0.05 was considered to be statistically significant., Results: Overall, CT-guided TFESI resulted in a substantial pain reduction in 46.6% of patients with discogenic radiculopathy. The contrast dispersion pattern and location had no effect on pain relief (p = 0.75 and p = 0.09) and PGIC (p = 0.70 and p = 0.21) 4 weeks after TFESI. Additionally, the experience of the radiologist had no influence on pain reduction (p = 0.92) or PGIC (p = 0.75). Regarding pre-interventional imaging findings, both the location and grading of nerve compression had no effect on pain relief (p = 0.91 and p = 0.85) and PGIC (p = 0.18 and p = 0.31)., Conclusion: Our results indicate that neither contrast agent dispersion/location nor the experience of the radiologist allows predicting the therapeutic outcome 4 weeks after the procedure., (© 2021.

Objective: To examine the impact of the presence of facet tropism on the results of transforaminal epidural steroid injection for unilateral radicular pain induced by lumbar disc herniation., Materials and Methods: We included 112 patients diagnosed with unilateral, single-level lumbar disc herniation-induced radicular pain. Injection was planned at relevant levels. The patients were assessed using the Numerical Rating Scale, the Modified Oswestry Disability Index, and the Beck Depression Inventory before the injection and at hour 1, week 3, and month 3 after the injection. Presence of facet tropism was assessed by measuring the facet angles in the L3-4, L4-5, and L5-S1 segments of lumbar MRI T2 sequence axial section., Results: A significant decrease in the Numerical Rating Scale and an increase in the Modified Oswestry Disability Index scores were detected at all follow-ups in groups comprising 39 patients with and 61 without facet tropism (p < 0.05). On comparison, improvement in clinical parameters at week 3 and month 3 in the group without facet tropism was greater (p < 0.05). As treatment success is considered to be a ≥ 50% reduction in the Numerical Rating Scale scores, 55.2% of the patients attained treatment success at month 3. Further, although the treatment success rate in the group with facet tropism was 34.2%, it was 69% in that without facet tropism (p < 0.05)., Conclusion: Facet tropism correlates with less success of transforaminal epidural steroid injection; therefore, facet tropism may be a worthwhile measurement in a discussion with patients of the benefits of the procedure.

We describe the case of a 30-year-old patient who was referred for lumbar epidural corticosteroid injection due to right L5 radiculopathy. Two months earlier, MRI demonstrated a right large paracentral L4-L5 disk extrusion causing disabling L5 radiculopathy. The L4-L5 level was selected for interlaminar injection, using fluoroscopic guidance. During injection, the patient developed severe pain in both lower extremities. Thus, the procedure was immediately terminated. Paraplegia occurred within several minutes. Urgent lumbar spine CT and MRI demonstrated contrast material in a massive extruded disk fragment and substantial increase in size of the disk extrusion compared to pre-injection MRI. Emergency surgery was performed for lumbar decompression and discectomy. Although rare, serious neurological complication can result from inadvertent intradiscal injection of contrast material during lumbar epidural injection. This case illustrates the importance of recognizing the possibility of dynamic change in the size of an extruded disk fragment when the MRI precedes injection by a substantial time interval. LEVEL OF EVIDENCE: IV, Case Series.

Introduction: The treatment of persistent cervical radicular pain (CRP) by CT-guided epidural steroid injections (CTESI) by a transforaminal anterolateral (TFA) approach is associated with rare but serious complications. Two recently described transforaminal posterolateral (TFP) and transfacet indirect (TFT) approaches may be safer options, but have not been extensively evaluated. We compared the efficacy of three CTESI approaches (TFA, TFP, and TFT) in the treatment of persistent CRP (>6 weeks)., Methods: Patients were prospectively assessed for pain using the visual analog scale (VAS) and for functional disability by the Neck Disability Index (NDI) before treatment, then 6 weeks and 6 months after CTESI., Results: A total of 104 patients were included (n = 30 TFA, n = 36 TFP, and n = 38 TFT approaches). Each group was found to have a statistically significant improvement at 6 weeks (median VAS values: 7 (2-9) at D0 and 2 (3-6) at 6 weeks p < 0.01; median NDI values: 38 (24-50) at D0 and 29 (18-42) at 6 weeks (p < 0.01)), and at 6 months (median VAS values: 7 (2-9) at D0 and 4 (2-6) at 6 months (p < 0.01); median NDI values: 38 (24-50) at D0 and 28 (13-40) at 6 months (p < 0.01)). No significant difference was observed in the decrease in VAS and NDI scores among the three approaches at 6 weeks (p = 0.635 and p = 0.54 for VAS and NDI respectively) or 6 months (p = 0.704 and p = 0.315 for VAS and NDI respectively). No major complications were noted., Conclusion: The results of CTESI using the TFP or TFT approach are similar to those for TFA in the treatment of persistent CRP and could be a safer option.

Purpose: To assess the technical feasibility, safety and initial clinical efficacy of a combined ultrasound and fluoroscopy imaging approach to cervical nerve root blocks. Fluoroscopic guided cervical transforaminal and selective nerve root injections are often used in the investigation or treatment of radicular symptoms, although rare but serious complications including death have been reported. We report a combined technique developed to increase safety of selective nerve root injections, including the safety and early efficacy of this novel technique in our initial patient cohort., Methods: We retrospectively reviewed a consecutive cohort of injections performed in 149 patients by a single consultant radiologist between December 2010 and August 2012. For all patients the outcome was assessed both immediately following the procedure and at six weeks. Primary outcome was reduction in radicular symptom level. Duration of symptoms were also assessed and all complications were recorded., Results: One hundred and forty nine patients underwent injection at either one or two cervical levels. No patients experienced any complications during the follow-up period, and 72 % had an initial positive response to the injection. Of these, 42 % were discharged to the care of their General Practitioner, 23 % went on to have surgery, 18 % were actively monitored in a specialist clinic, 10 % were referred to our pain management service and 4 % had the injection repeated after symptoms recurred., Conclusion: Using this combined image guided technique cervical nerve root blocks appear both safe and effective in the investigation and management of radicular symptoms from the cervical spine.

Objectives: To describe all the CT findings after in situ contrast injection just before steroid injection and to recognize the abnormal aspects associated with intravascular contamination., Material and Methods: We retrospectively evaluated 248 cervical transforaminal steroid injections done at the university hospital in Dijon, France, in 2008-2012, to treat cervicobrachial neuralgia inadequately improved by optimal medical treatment for at least 3 weeks. Features describing the opacification patterns were recorded., Results: Five main nonvascular opacification patterns were identified: clumps of contrast agent outside the foramen (16 %), a crab claw pattern surrounding the ganglion (13 %), a "French" circumflex accent pattern (15 %), reflux along the needle (7 %), and facet joint capsule opacification (22 %). Concerning the situations requiring a change in needle position, intravenous injection occurred in 26 % of the patients, with a crab claw pattern in half the cases and a clump pattern in half the cases. Intraarteriolar injection was noted in two patients., Conclusion: CT after in situ contrast injection ensures proper needle positioning outside the blood vessels before steroid injection. Penetration of the needle tip into a vein is very common, whereas arteriolar puncture is extremely rare.

Objective: The purpose of this study is to analyze the effectiveness of fluoroscopic cervical paramidline interlaminar epidural steroid injection (ESI) as well as to assess outcome predictors., Methods: One hundred forty-three patients (M:F = 89:54, mean age = 53.1 years old) who received cervical paramidline interlaminar ESIs in 2011 were included in this study. Initial improvements at 2 weeks were assessed. For possible outcome predictors, clinical and MR variables were statistically analyzed using the Mann-Whitney U, Chi-square, and Fisher's exact tests., Results: Initial improvements after cervical paramidline interlaminar ESIs at 2 weeks were reported in 115 of 143 patients (80.8%). Patients with paresthesia only and no pain showed significantly fewer improvements after ESIs (11/19, 57.9%) than patients with pain (104/124, 83.9%) (p = 0.013). Other variables were not statistically significant outcome predictors., Conclusions: Fluoroscopic paramidline interlaminar cervical ESIs effectively managed cervical radiculopathy, irrespective of the cause or zone of nerve root compression, and patients with paresthesia only experienced fewer improvements.

Introduction: CT-guided cervical nerve root injection with corticosteroid and/or local anesthetic is a recognized technique in the evaluation and treatment of cervical radiculopathy. There are few prospective studies on the efficacy of the various techniques employed in cervical nerve root injection. We present our results from a 1-year prospective series using a CT-guided anterolateral transforaminal approach for cervical nerve root injection of bupivacaine and dexamethasone., Methods: Pain using a numeric rating scale was assessed at pre-injection, 15 min post-injection, 1 month, and 3 months. Disability was assessed using the Oswestry Neck Disability Index (NDI) questionnaire at pre-injection, 1 month post-injection, and 3 months., Results: In total, 50 patients were followed for 3 months. The mean reductions in pain were: 15 min (77 %), 1 month (39 %), and 3 months (33 %). The mean reductions in NDI were: 1 month (26 %) and 3 months (also 26 %). Results were statistically significant., Conclusions: CT-guided selective cervical nerve root injection in the treatment of cervical radicular pain and related disability produces statistically significant reductions in pain and disability to at least 3 months post-procedure.

Purpose: To evaluate the accuracy, safety, and efficacy of cervical nerve root injection therapy using magnetic resonance guidance in an open 1.0 T MRI system., Methods: Between September 2009 and April 2012, a total of 21 patients (9 men, 12 women; mean age 47.1 ± 11.1 years) underwent MR-guided cervical periradicular injection for cervical radicular pain in an open 1.0 T system. An interactive proton density-weighted turbo spin echo (PDw TSE) sequence was used for real-time guidance of the MR-compatible 20-gauge injection needle. Clinical outcome was evaluated on a verbal numeric rating scale (VNRS) before injection therapy (baseline) and at 1 week and 1, 3, and 6 months during follow-up., Results: All procedures were technically successful and there were no major complications. The mean preinterventional VNRS score was 7.42 and exhibited a statistically significant decrease (P < 0.001) at all follow-up time points: 3.86 ± 1.53 at 1 week, 3.21 ± 2.19 at 1 month, 2.58 ± 2.54 at 3 months, and 2.76 ± 2.63 at 6 months. At 6 months, 14.3 % of the patients reported complete resolution of radicular pain and 38.1 % each had either significant (4-8 VNRS score points) or mild (1-3 VNRS score points) relief of pain; 9.5 % experienced no pain relief., Conclusion: Magnetic resonance fluoroscopy-guided periradicular cervical spine injection is an accurate, safe, and efficacious treatment option for patients with cervical radicular pain. The technique may be a promising alternative to fluoroscopy- or CT-guided injections of the cervical spine, especially in young patients and in patients requiring repeat injections.

Objective: This study aimed to determine whether the presence of type 2 diabetes impairs the therapeutic response to transforaminal cervical epidural steroid injections (TF-CESI) in the treatment of pain due to cervical radiculopathy., Design: This is a retrospective cohort study of patients with cervical radiculopathy who underwent TF-CESI performed by a single physician., Setting: Single community-based multidisciplinary pain clinic and ambulatory surgery center., Interventions: Patients underwent from one to three TF-CESI with dexamethasone or triamcinolone., Main Outcome Measures: Change in self-reported numerical pain score., Results: Out of 387 charts reviewed, complete data were available for 329 subjects who underwent TF-CESI from February 2006 through January 2010. The injections consisted of either 40 mg triamcinolone or 15 mg dexamethasone. Of the 329 total subjects, 35 had type 2 diabetes and 294 did not. The diabetic group had a mean age of 58.1 years with standard deviation (SD) of 11.2, mean body mass index (BMI) of 33.1 (SD 7.1), mean pre-procedure pain score of 6.7 (SD 2.2) and mean reduction in pain score of 2.5 (SD 2.4). The non-diabetic group had a mean age of 52.8 (SD 12.4), mean BMI of 28.2 (SD 5.4), mean pre-procedure pain score of 6.7 (SD 1.8), and mean reduction in pain score of 2.4 (SD 2.2). A two-sample t test with equivalent variance showed no statistically significant difference in the mean reduction in pain score between the diabetic and non-diabetic groups. The patients in the diabetic group were typically older and had higher BMIs., Conclusions: The efficacy of TF-CESI for treating cervical radicular pain in this set of 329 patients was independent of the presence of type 2 diabetes.

Objectives: To compare the short-term effects and advantages of ultrasound-guided selective nerve root block with fluoroscopy-guided transforaminal epidural block for radicular pain in the lower cervical spine through assessment of pain relief, functional improvement, and safety., Methods: A total of 120 patients with radicular pain from cervical spinal stenosis or cervical herniated disc were enrolled. All procedures were performed using a fluoroscopy or ultrasound apparatus. The subjects were randomly assigned to either the fluoroscopy (FL) or ultrasound (US) group. The complication frequencies during the procedures, treatment effects, and functional improvement of the nerve root block were compared at 2 and 12 weeks after the procedures., Results: Verbal Numeric Pain Scale (VNS) improved 2 weeks and 12 weeks after the injections in both groups. Statistical differences were not observed in VNS, Neck Disability Index (NDI), and effectiveness between the groups. In 21 patients at US, vessels were identified at the anterior aspect of the foramen. Eleven patients had a critical vessel at the posterior aspect of the foramen and five patients had on artery continue medially into the foramen, forming, or joining a segmental feeder artery. In both cases, the vessels might well have been in the pathway of the needle correctly positioned under fluoroscopic guidance. Five cases of intravascular injections were observed only in FL without significant difference between the groups., Conclusions: The US-guided method may facilitate identifying critical vessels at unexpected locations relative to the intervertebral foramen and avoiding injury to such vessels, which is the leading cause of the reported complications from cervical transforaminal injections. On treatment effect, using either method of epidural injections to deliver steroids for cervical radicular pain, secondary to herniated intervertebral disc or foraminal stenosis, significant improvements in function and pain relief were observed in both groups after the intervention. However, significant difference was not observed between the groups. Therefore, the ultrasound-guided method was shown to be as effective as the fluoroscopy-guided method in pain relief and functional improvement, in addition to the absence of radiation and avoiding vessel injury at real-time imaging.

Objectives: To evaluate the efficacy of a single direct epidural injection of tumor necrosis factor (TNF)-α inhibitor to reduce the pathological changes in nerve fiber injuries in a rat model of chronic compression of the dorsal root ganglion (CCD)., Materials and Methods: A surgical procedure for CCD was performed in 17 adult male F-344 rats. The effects of the epidural TNF-α inhibitors on CCD-induced pathological changes were investigated. Three groups of rats (n = 17) were used: (1) CCD + saline (n = 4), (2) CCD + triamcinolone (n = 5), and (3) CCD + TNF-α inhibitors (n = 8). Their dorsal root ganglia and nerve roots were removed on postoperative day 14. The intraneural edema, demyelination, and Wallerian degeneration of all 17 rats were scored pathologically., Results: The pathology scores of the rats in the TNF-α inhibitor treatment group (1.38 ± 0.74) indicated a mild degree of intraneural edema compared to the saline treatment group (2.25 ± 0.50, p = 0.041). In addition, rats in the TNF-α inhibitor treatment group (2.13 ± 0.35) had a mild degree of demyelination compared to the saline treatment group (2.75 ± 0.50, p = 0.038) and the triamcinolone treatment group (2.80 ± 0.45, p = 0.019). The differences in the pathology scores for Wallerian degeneration were not statistically significant in all three study groups (p = 0.658)., Conclusion: The epidural injection of a TNF-α inhibitor was more effective than a placebo and comparable to triamcinolone in reducing pathological nerve injury progression.

Objective: To determine if a particulate steroid which has a risk for embolic infarct would be more effective than a non-particulate steroid for transforaminal epidural steroid injection (TFESI). The purpose of this study was (1) to compare the effect of cervical TFESI using particulate (e.g., triamcinolone) and non-particulate (e.g., dexamethasone) steroids and (2) to evaluate the effectiveness of cervical TFESI in general., Materials and Methods: From January 2006 to August 2008, 159 consecutive patients [male:female (M:F) 89:70; mean age 53 years, range 33-75 years] who underwent cervical TFESI were included in this non-randomized study. For cervical TFESI, triamcinolone was injected into 97 patients and dexamethasone into 62 patients. Short-term follow-up was conducted within 1 month. The outcome was classified as effective or ineffective. Fisher's exact test was used to analyze the difference of outcome according to the injected steroid (triamcinolone vs dexamethasone). Other possible outcome predictors, such as age, gender, duration of radiculopathy, predominant symptom, attack of radiculopathy, cause of radiculopathy, number of nerve root compression levels, previous operation, and failure of previous interlaminar epidural injection, were also analyzed., Results: Cervical TFESI using triamcinolone (78/97, 80.4%) was slightly more effective than that using dexamethasone (43/62, 69.4%), which was not significant (P = 0.129). In general, cervical TFESIs were effective in 121 of 159 patients (76.1%) at short-term follow-up. The only significant outcome predictor was whether the patient had had a previous operation (6/13, 46/2%) or not (115/146, 78.8%) (P = 0.015)., Conclusion: There was no significant difference between particulate or non-particulate steroid for the effect of cervical TFESI. Cervical TFESI was effective in managing cervical radiculopathy in general.

Objective: To verify the usefulness of a fluoroscopy guided cervical interlaminar epidural steroid injection (CIESI) in patients with neck pain and cervical radiculopathy and to evaluate outcome predictors., Design: We retrospectively analyzed 91 patients from July 2004 to June 2005 in whom CIESI was initially performed for neck pain and cervical radiculopathy. Therapeutic effects were evaluated 2 weeks after the administration of CIESI, and CIESI effectiveness was graded using a five-point scale, namely, whether the pain had disappeared, was much improved, slightly improved, the same, or aggravated. We also used a visual analog scale (VAS) for the clinical evaluation. According to documentation and follow-up charts, we categorized treatments as effective or ineffective. Possible outcome predictors, namely, diagnosis (spinal stenosis vs herniated disc), primary symptoms (neck pain vs radiculopathy vs both), age, gender, and duration of pain (more or less than 6 months) were also analyzed. Fisher's exact test, the chi-square test, and multiple logistic regression analysis were used for the statistical analysis., Patients: After their medical records had been reviewed, 76 patients were included in this study. Inclusion criteria were: the availability of a cross-sectional image, such as a CT scan or an MR image, and a follow-up record after injection., Results and Conclusions: The medical records of 76 patients (male:female = 41 : 35) of mean age 53.1 years (range 32 years to 82 years) were reviewed. Two weeks after injection, 55 patients (72.4%) had experienced effective pain relief. Patients with herniated discs had significantly better results than patients with spinal stenosis (86.1% vs 60.0%) (P < 0.05). Other non-significant predictors of an improved outcome included: a symptom duration of <6 months, a young age, and the presence of cervical radiculopathy. Multiple regression analysis showed that the only factor that was significantly associated with outcome was the cause of the pain, i.e., herniated disc or spinal stenosis. Fluoroscopy guided CIESI is a safe and effective means of treating patients with neck pain and cervical radiculopathy. The most important outcome predictor was cause of pain, and patients with herniated disc experienced better pain relief than those with spinal stenosis.

The disease of the spinal column is number 2 of common diseases world-wide and leads to high business- and commerce-related losses as well as to high expenses for the health care systems. An effective treatment of this disease is given by the microinvasive. CT controlled periradicular therapy (micro PRT). Under visibility, the tip of a canula is led directly and high precisely in close neighbourhood to the prolaps, then locally NaCl and cristaline cortisone (40 mg Volon A) is instillated. The periradicular distribution and the distribution into the epidural space is documented via contrast medium. A retrospective study with 220 patients and a prospective randomized double blind study with 40 patients (10 mg vs. 40 mg Volon A) were carried out. The average age of the retrospective collective was 53.1 +/- 12.4 years, average treatment period 18.4 weeks, and the mean follow-up 17 months. The mean value of successful treatment of lumbal spine was at 60% (spine 88.5%) with protrusion, with prolaps at 75% (spine 94%), with sequester at 94%, and with stenoses at 69% (spine 60%). With 78.8% of the patients, the percentual result was constantly good at the time of questionnaire as to the end of the treatment. 7.7% still took analgesics, 5.9% were post-operated. 1.8% of the patients made a pension application. The average age of patients within the prospective randomized double-blind-study was 47.2 +/- 11.9 years. At 27.5% of the patients, the start of pain was about more than 5 years ago and goes back to about 23 years (72.5% had pain more than 1 year). The mean value of visits was 4 physicians per patient, and 5 months of follow-up. There is a high significant improvement in results within the group with 40 mg Volon A (p = 0.0351479). The entire improvement, subjectively estimated (visual analogical scale) within this group was at 90%. After end of therapy, 83.3% (n = 30) had stopped the taking of analgesics and the neurologic deficit decreased significantly.

Patients treated with Nefo-Dolpasse showed a smaller rate of side effects than those treated with comparable solutions.
