Background: Thoracic facet joints have been implicated as the source of chronic pain in the mid back or upper back in 34% to 42% of patients when the modified criteria of the International Association for the Study of Pain (IASP) is utilized. Various therapeutic techniques utilized in managing chronic thoracic pain of facet joint origin include intraarticular injections, medial branch blocks, and radiofrequency neurotomy of thoracic medial branch nerves. Study Design: A randomized, double-blind, active controlled trial. Setting: A private practice, interventional pain management setting, and a specialty referral center setting in the United States. Objective: To determine the clinical effectiveness of therapeutic local anesthetic medial branch blocks with or without steroid in managing chronic function-limiting mid back or upper back pain of facet joint origin. Methods: The study was performed in an interventional pain management private practice, a tertiary referral center, in the United States. A total of 100 participants were included, with 50 participants in each of the local anesthetic and steroid groups. All of the participants met the diagnostic criteria of thoracic facet joint pain by means of comparative, controlled diagnostic blocks and the inclusion criteria. Group I participants received thoracic medial branch blocks with bupivacaine, whereas Group II participants received thoracic medial branch blocks with bupivacaine and non-particulate betamethasone. Outcomes Assessment: Outcomes measures included numeric rating scores (NRS), Oswestry Disability Index (ODI), opioid intake, and return to work status at baseline, 3 months, 6 months, and 12 months. Significant pain relief was defined as ≥ 50% pain relief and/or a positive change in ODI scores. Results: In Group I and Group II 90% of participants showed significant pain relief and functional improvement at 12 months. The majority of the participants experienced significant pain relief of 47.2 ± 10.1 weeks in Group I and 46.3 ± 8.4 weeks in Group II, requiring approximately 3.5 treatments per year with an average relief of 15.8 ± 10.5 in Group I and 13.6 ± 3.6 weeks in Group II per episode of treatment. Limitations: Study limitations include the lack of a placebo group. Conclusions: Therapeutic thoracic medial branch blocks, with or without steroid, may provide a management option for chronic function-limiting mid back or upper back pain of facet joint origin.

Background: The proportion of patients suffering from thoracic pain secondary to thoracic disorders is relatively small compared to low back and neck pain. Furthermore, thoracic interventions are not performed as often as in cervical and lumbar regions. In addition, there is a paucity of literature regarding thoracic intervertebral discs and thoracic disc herniation as causative structures of thoracic pain. Study Design: A randomized, double-blind, active controlled trial. Setting: A private practice, interventional pain management and specialty referral center in the United States. Objectives: To evaluate the effectiveness of thoracic interlaminar epidural injections in providing effective pain relief in managing chronic mid and upper back pain secondary to disc herniation or radiculitis and discogenic pain with local anesthetic alone or with steroids. Methods: Inclusion criteria consisted of patients who either had disc herniation or radiculitis, or patients with discogenic pain proven by controlled comparative local anesthetic blocks not to be caused by facet joint pain. Patients were assigned to one of 2 groups. One group received injections containing local anesthetic only; the other group, local anesthetic mixed with nonparticulate betamethasone. Randomization was performed by computer-generated random allocations sequence by simple randomization. Outcomes Assessment: Participant outcomes were measured at baseline, 3, 6, and 12 months post-treatment with the Numeric Rating Scale (NRS), the Oswestry Disability Index 2.0 (ODI), employment status, and opioid intake. Decrease of ≥ 50% of NRS scores and Oswestry scores were considered significant. Results: A total of 40 participants are included in this preliminary report with 20 participants in each group. Significant pain relief (≥ 50%) and reduction (by at least 50%) in ODI from baseline was seen at 12 months in 80% of patients in Group I and 85% in Group II. Limitations: This is a preliminary report and there was no placebo group. Conclusion: Overall, 80% of participants in Group I (who received injections without steroids) and 85% in Group II (who received injections with steroids) with thoracic pain secondary to disc herniation or radiculitis and discogenic pain might benefit from thoracic interlaminar epidural injections.

Background: Cervical spinal stenosis is a common disease that results in considerable morbidity and disability. There are multiple modalities of treatments, including surgical interventions and multiple interventional techniques including epidural injections. The literature on the effectiveness of cervical epidural steroids is sporadic. Emerging evidence for cervical interlaminar epidurals for various conditions in the cervical spine is positive; however, the effect of fluoroscopic epidural injections in cervical spinal stenosis has not been studied. Study Design: A randomized, double-blind, active control trial. Setting: A private interventional pain management practice, a specialty referral center in the United States. Objectives: To evaluate the effectiveness of cervical interlaminar epidural injections with local anesthetic with or without steroids in the management of chronic neck pain with upper extremity pain in patients with cervical central spinal stenosis. Methods: Patients with cervical central spinal stenosis were randomly assigned to one of 2 groups: injection of local anesthetic only or local anesthetic mixed with non-particulate betamethasone. Sixty patients were included in this analysis. Randomization was performed by computer-generated random allocation sequence by simple randomization. Outcomes Assessment: Multiple outcome measures were utilized including the Numeric Rating Scale (NRS), the Neck Disability Index (NDI), employment status, and opioid intake with assessment at 3, 6, and 12 months post-treatment. Significant pain relief or functional status was defined as a 50% or more reduction of NRS or NDI scores. Results: Significant pain relief was seen in 73% in Group I and 70% in Group II, in Group II showing both significant pain relief and functional status improvements. Group I’s average relief per procedures was 11.3 ± 5.8 weeks; for Group II it was 8.6 ± 3.6 weeks, whereas after initial 2 procedures, average relief was 13.7 ± 8.7 weeks in Group I, and 13.6 ± 4.7 weeks in Group II. In the successful group, the average total relief in a one-year period was 42.2 ± 14.7 weeks in Group I and 34.3 ± 13.4 weeks in Group II, with 76% in Group I and 77% in Group II. Limitations: Study limitations include the lack of a placebo group and that this is a preliminary report of only 60 patients, 30 in each group. Conclusion: Patients who have chronic function-limiting pain that is secondary to cervical central stenosis might receive relief with cervical interlaminar epidurals of local anesthetic, whether with or without steroids.

Background: Reports of prevalence of spinal pain indicate the prevalence of thoracic pain in approximately 13% of the general population compared to 32% of the population with neck pain and 43% of the population with low back pain during the past year. Even though, thoracic pain is less common than neck or low back pain, the degree of disability resulting from thoracic pain disorders seems to be similar to other painful conditions. Interventions in managing chronic thoracic pain are also less frequent, leading to the paucity of literature about various interventions in managing chronic thoracic pain. Thoracic intervertebral discs and thoracic facet joints have been shown to be pain generators, even though thoracic radicular pain is very infrequent. Thoracic epidural injections are one of the commonly performed procedures in managing thoracic pain. The efficacy of thoracic epidural injections has not been well studied. Study Design: A randomized, double-blind, active controlled trial. Setting: Private interventional pain management practice and specialty referral center in the United States. Objective: The primary objective was to assess the effectiveness of thoracic interlaminar epidural injections in providing effective pain relief and improving function in patients with chronic mid and/ or upper back pain. Methods: One hundred and ten patients were randomly assigned into 2 groups with 55 patients in each group receiving either local anesthetic alone (Group I) or local anesthetic with steroids (Group II). Randomization was performed by computer-generated random allocation sequence by simple randomization. Outcomes Assessment: Outcomes were assessed utilizing Numeric Rating Scale (NRS), the Oswestry Disability Index (ODI) 2.0, employment status, and opioid intake. The patients experiencing greater than 3 weeks of significant improvement with the first 2 procedures were considered as successful. Others were considered as failed participants. Significant improvement was defined as a decrease of greater than 50% NRS scores and ODI scores with measurements performed at baseline, 3, 6, 12, 18, and 24 months post treatment. Results: Significant improvement was seen in 71% in Group I and 80% in Group II at the end of 2 years with all participants; however, improvement was seen in 80% and 86% when only successful patients were considered. Therapeutic procedural characteristics showed 5 to 6 procedures per 2 years with total average relief of 80 weeks in Group I and 78 weeks in Group II in the successful patient category; whereas, it was 71 and 72 weeks when all patients were considered. Limitations: Limitations of this assessment include lack of a placebo group.Conclusions: Based on the results of this trial, it is concluded that chronic thoracic pain of non-facet joint origin may be managed conservatively with thoracic interlaminar epidural injections with or without steroids.

Background: The pathophysiology of lumbar radicular pain is a subject of ongoing research. The prevalence of sciatica or radiculitis ranges from 1.2% to 43%. Epidural injections are one of the most commonly performed interventions in the United States in managing chronic low back and lower extremity pain secondary to disc herniation and radiculitis. There is a paucity of evidence with contemporary methodology used in performing epidural injections under fluoroscopy and based on pain relief and functional status improvement. Study Design: A randomized, double-blind, equivalence trial. Setting: An interventional pain management practice, a specialty referral center, a private practice setting in the United States. Objective: To evaluate the effectiveness of caudal epidural injections with or without steroids in managing chronic low back and lower extremity pain secondary to disc herniation or radiculitis in providing effective and long-lasting pain relief and evaluate the differences between local anesthetic with or without steroids. Methods: Patients were assigned to one of 2 groups; Group I patients received caudal epidural injections with an injection of local anesthetic (lidocaine 0.5%), whereas, Group II patients received caudal epidural injections with 0.5% lidocaine 9 mL mixed with 1 mL of steroid. Randomization was performed by computer-generated random allocations sequence by simple randomization. Outcomes Assessment: Multiple outcome measures were utilized which included the Numeric Rating Scale (NRS), the Oswestry Disability Index 2.0 (ODI), employment status, and opioid intake with assessment at 3 months, 6 months, and 12 months post-treatment. Significant pain relief was defined as 50% or more, whereas significant improvement in disability score was defined as a reduction of 40% or more. Results: The percentage of patients with significant pain relief of 50% or greater at 12 months was 79% in Group I and 81% in Group II. Reduction of Oswestry scores of at least 40% was seen in 83% of the patients in Group I and 91% in Group II. The overall average procedures per year were 3.9 ± 1.26 in Group I and 3.6 ± 1.08 in Group II with an average total relief per year of 35.2 ± 17.18 weeks in Group I and 35.9 ± 15.34 weeks in Group II over a period of 52 weeks. Limitations: The results of this study are limited by lack of a placebo group and a preliminary report of 42 patients in each group. Conclusion: Caudal epidural injections with or without steroids may be effective in patients with disc herniation or radiculitis with between 79% to 91% of patients showing significant pain relief and improvement in functional status.

Background: The pathophysiology of lumbar radicular pain is the subject of ongoing research, with a reported prevalence of sciatica or radiculitis ranging from 1.2% to 43%. Among the numerous nonsurgical interventions available, epidural injections are the most commonly performed interventions in the United States in managing chronic low back and lower extremity pain. Study Design: A randomized, double-blind, controlled trial. Setting: An interventional pain management practice, a specialty referral center, a private practice setting in the United States. Objective: To evaluate the effectiveness of lumbar interlaminar epidural injections with local anesthetic, with or without steroids, in managing chronic low back and lower extremity pain secondary to disc herniation or radiculitis in providing effective and long-lasting pain relief. Methods: Patients were assigned to one of 2 groups with local anesthetic only or with local anesthetic mixed with non-particulate betamethasone. Randomization was performed by computer-generated random allocations sequence by simple randomization. Seventy patients were included in this analysis. Outcomes Assessment: Patient outcomes were measured at baseline, 3, 6, and 12 months post-treatment with the Numeric Rating Scale (NRS), the Oswestry Disability Index 2.0 (ODI), employment status, and opioid intake. Decrease of ≥ 50% of NRS scores and Oswestry scores were considered significant. Results: Significant pain relief (≥ 50%) was seen at 12 months in 74% of patients in Group I and 86% in Group II, and 69% and 83% in ODI scores respectively. Significant differences were noted in pain relief characteristics at 6 months between Group I and Group II (P = 0.001) and functional status improvement was significantly better in Group II at 6 months and 12 months (P = 0.019 and 0.045). The overall average procedures per year were 4.3 in Group I and 4.2 in Group II with an average total relief per year of 42.2 ± 10.5 weeks in Group I and 41.4 ± 11.0 weeks in Group II over a period of 52 weeks in the successful group. Limitations: The study limitations include the lack of a placebo group and the fact that this is a preliminary report of 35 patients in each group. Conclusion: Overall, 74% of patients in Group I without steroids and 86% in Group II with steroids with lumbar disc herniation or radiculitis might benefit from lumbar interlaminar epidural injections.

Background: Cervical therapeutic intraarticular facet joint injections, therapeutic medial branch blocks, and radiofrequency neurotomy have been applied in managing chronic neck pain of cervical facet joint origin. However, the effectiveness of these modalities continues to be debated. The purpose of this study was to determine the clinical effectiveness of therapeutic cervical medial branch blocks with or without steroids. Study Design: A randomized, double-blind, controlled trial. Setting: An interventional pain management practice, a specialty referral center, a private practice setting in the United States. Objective: To evaluate the clinical outcomes of therapeutic cervical medial branch blocks with local anesthetic with or without steroids in managing chronic neck pain of facet joint origin. Methods: A total of 120 patients meeting inclusion criteria were included. All of the patients met the diagnostic criteria of cervical facet joint pain by means of comparative, controlled diagnostic blocks, with at least 80% relief. Group I consisted of cervical medial branch blocks with bupivacaine only and Group II consisted of cervical medial branch blocks with bupivacaine and steroid. Therapeutic cervical medial branch blocks with local anesthetic with or without steroids were administered. Main outcome measures included numeric pain scores, Neck Disability Index (NDI), opioid intake, and work status evaluated at baseline, 6, 12, 18, and 24 months. The one-year results of outcomes were published in 2008. This manuscript describes the 2-year results. Significant improvement was defined as at least 50% improvement in pain relief and/or functional status improvement. Outcomes Assessment: Patient outcomes were measured at baseline, 3, 6, 12, 18, and 24 months post-treatment with the Numeric Rating Scale (NRS), the Neck Disability Index (NDI), employment status, and opioid intake. Decrease of ≥ 50% of NRS scores and Oswestry scores were considered significant. Results: Eighty-five percent of patients in Group I and 93% of patients in Group II showed significant pain relief (≥ 50%) at 2 years. The average number of treatments for 2 years was 5.7. The duration of average pain relief with each procedure was 17-19 weeks on average in both groups. Significant improvement of pain and function was demonstrated for 83 to 89 weeks over a period of 2 years. Limitations: The study limitations include the lack of a placebo group. Conclusions: In this study, therapeutic cervical medial branch blocks instituted after the diagnosis, with controlled comparative local anesthetic blocks with 80% concordant pain relief, repeated approximately 6 times over a period of 2 years, provided significant improvement over a period of 2 years.

Objective: Trigeminal neuralgia is the lancinating electric shock like pain because of neurovascular compression in trigeminal nerve distribution. We compared the efficacy of radiofrequency rhizotomy with microvascular decompression in terms of complete pain relief.Material and Methods: The randomized controlled trial study was conducted in the neurosurgery department, LGH Lahore for a period of one year June 2017 to June 2018. A total of 110 patients were included and distributed into two groups, i.e. group-I who underwent radiofrequency rhizotomy (RFR) and group-II who underwent microvascular decompression (MVD). Follow-up of all the patients was assured up to six months. All the data were analyzed using S.P.S.S Ver. 23.0.Results: There were 38 (34.6%) male and 72(65.4%) female. Mean age was 51.25 ± 8.80 years. At the end of six months, in Group-I (RFR), Nineteen (34.5%) patients were completely pain free, 25 (45.5%) patients had significant pain relief, 7 (12.7%) had mild improvement in the pain and 4 (7.3%) patients had no improvement in the pain. In group-II (MVD), 30 (54.5%) patients were completely pain free, 14 (25.5%) had significant pain relief, 9 (16.4%) had mild improvement and 2 (3.6%) had no improvement in their pain (Chi-square = 6.49, p = 0.090).Conclusion: Microvascular decompression had better results than a radiofrequency rhizotomy in patients presenting with trigeminal neuralgia regarding excellent pain relief and fewer complications.

Joint Injections

Intra-articular facet joint injections commonly refer to the injection of a contrast media and local anesthetic solution, with or without corticosteroids, directly into the facet joint space. The purpose of this procedure is pain relief as well as to establish an etiological diagnosis for surgical interventions such as joint denervation or radiofrequency ablation. Medial branch block, or facet nerve block, refers to injection of local anesthetic and possible corticosteroids along the medial branch nerve supplying the facet joints. Cervical intra-articular and facet nerve block injections are often part of a work-up for general or focal neck pain, headaches, or cervical muscle spasms. There is limited evidence for short- and long-term pain relief with cervical intra-articular facet joint injections. Cervical medial branch nerve blocks with local anesthetics demonstrate moderate evidence for short- and long-term pain relief with repeat interventions, and strong evidence exists for long-term pain relief following cervical radiofrequency neurotomy.
