Background: An epidural steroid injection (ESI) is usually used for the treatment of low back pain with radiculopathy. An ESI can be performed by two procedures: I) a lumbar or caudal epidural steroid injection and II) a transforaminal epidural steroid injection. Methods: Ninety-three patients, who had undergone transforaminal epidural steroid injection (Group II), and either a lumbar or caudal epidural steroid injection (Group I), were retrospectively studied. The authors assessed the pain, walking, standing improvement and side effects after each procedure, which were evaluated as being very good, good, fair or poor. Data were collected from the patients medical records and analyzed using the chi-squared test. P < 0.05 was considered significant. Results: There were no statistically significant differences in the pain, walking, standing improvement and side effects between the two groups. However, there was a statistically significant difference in the pain improvement following transforaminal epidural steroid injection in those not effectively responding to an initial lumbar or caudal epidural block in Group II. Conclusions: A transforaminal epidural steroid injection is a useful alternative to a lumbar or caudal epidural steroid injection for low back pain with radiculopathy.

Coccygodynia is a pain syndrome resulting from trauma, fractures, infection and tumor, and is usually amenable to conservative treatment. We present one case of coccygodynia that developed 2 days after percutaneous cordotomy done for pain control of cervix cancer unresponsive to conservative treatment which subsequently was treated with a caudal injection of lidocaine and triamcinolone. Caudal epidural steroid injection is less invasive and has less potential for complication than the neurosurgical interruption of the pain pathway.

Background: Epidural injections are performed utilizing 3 approaches in the lumbar spine: caudal, interlaminar, and transforaminal. The literature on the efficacy of epidural injections has been sporadic. There are few high-quality randomized trials performed under fluoroscopy in managing disc herniation that have a long-term follow-up and appropriate outcome parameters. There is also a lack of literature comparing the efficacy of these 3 approaches. Methods: This manuscript analyzes data from 3 randomized controlled trials that assessed a total of 360 patients with lumbar disc herniation. There were 120 patients per trial either receiving local anesthetic alone (60 patients) or local anesthetic with steroids (60 patients). Results: Analysis showed similar efficacy for caudal, interlaminar, and transforaminal approaches in managing chronic pain and disability from disc herniation. The analysis of caudal epidural injections showed the potential superiority of steroids compared with local anesthetic alone a 2-year follow-up, based on the average relief per procedure. In the interlaminar group, results were somewhat superior for pain relief in the steroid group at 6 months and functional status at 12 months. Interlaminar epidurals provided improvement in a significantly higher proportion of patients. The proportion of patients nonresponsive to initial injections was also lower in the group for local anesthetic with steroid in the interlaminar trial. Conclusions: The results of this assessment show significant improvement in patients suffering from chronic lumbar disc herniation with 3 lumbar epidural approaches with local anesthetic alone, or using steroids with long-term follow-up of up to 2 years, in a contemporary interventional pain management setting.

Background: A transforaminal epidural steroid injection has been used for the treatment of radicular arm or leg pain, which has the advantage of ventral epidural spreading compared to either an interlaminar or caudal approach. However, several factors are known to affect the epidural spread pattern of contrast dye; therefore, the injected medication can not be delivered to the target site. The objective of our study was to observe any differences in the contrast flow patterns according to several factors. Methods: A total of 34 epidurographies in 29 patients, who underwent fluoroscopically guided transforaminal epidural steroid injections, were evaluated. After confirming the location of the needle tip within the anterior superior aspect of the neural foramen in the lateral view, and at the 6 o'clock position to the pedicle in the anteroposterior view, 2 ml of contrast dye was injected. The contrast flow patterns of ventral, ventral and dorsal, and dorsal epidural filling were analyzed, according to age, gender, magnetic resonance imaging finding and history of previous back surgery. Results: Ventral contrast flow occurred in 30 out of the 34 epidurographies (88%). Both ventral and dorsal contrast flow patterns were observed 13 out of 16 (81%) patients in the older age group. Also, both ventral and dorsal contrast flow patterns were observed in 16 out of 18 (88%) patients with spinal stenosis. Conclusions: Transforaminal epidural steroid injections, performed uner fluoroscopy, provide excellent nerve root filling and ventral epidural spreading. Patients with spinal stenosis or an old age have both ventral and dorsal epidural spreading patterns.

Background: Epidural steroid injections (ESI) have been used widely for the treatment of back and radiating extremity pain. Although its effects on the metabolic and endocrine system have been studied, the effects following repeated injections remain to be determined. We studied the effects of three repeated caudal epidural injections of low dose triamcinolone. Methods: the subject were 10 elderly women with spinal stenosis. Caudal epidural injections were performed biweekly. Triamcinolone (20 mg), mixed with 15 ml of 0.25% lidocaine, was used as the ESI injectate. The procedures were performed with the patient in the prone position. Blood sampling was performed just before the first injection, and used as the baseline, and then just before each injection on the same day of the 2nd and 4th weeks, with the last samples taken 2 weeks after the third injection. Results: The blood glucose concentrations showed no significant changes. The blood cortisol and ACTH concentrations were significantly decreased after the first injection, but there were no further decreases after each of the subsequent injections. The cortisol concentrations were maintained within the normal range. Conclusion: Caudal epidural injections, with low dose triamcinolone, suppressed the hypothalamus-pituitary-adrenal (HPA) axis, but no further suppression followed the subsequent repeated injections. Three consecutive caudal injections at 2 week intervals seems to be a safe procedure.

Caudal epiduroscopy has been introduced as an alternative technique for direct injection of epidural steroid and lysis of adhesion. Futher, it gives a better understanding of the role of epidural adhesion in recurrence of sciatica and low back disorder after surgery. We experienced a clinical application of flexible fiberoptic epiduroscope inserted through the sacral canal. A 37-year-old woman was suffering from right lumbar radiculopathy after an operation for a herniated disc. A series of volumetric caudal steroid injections and physical therapy had little effect on her symptoms. Patient was thought to be a good candidate for epiduroscopy. Flexible flberoptic epiduroscopy was as follows: 60 ml of normal saline irrigation and epidurogram, 40 mg of triamcinolone in 10m1 of normal saline was directed around right L5 nerve root. The following morning, patient reported reduced pain in her leg.

Background: Coccygodynia is one of the chronic, refractory painful musculoskeletal disorders. Interventional procedures are applied to patients unresponsive to initial treatment in coccygodynia. This study aims to compare the treatment outcomes of ganglion impar block (GIB) and caudal epidural steroid injection (CESI) in patients with chronic coccygodynia. Methods: This study was a prospective randomized comparison study conducted between June 2019 and January 2021. Patients diagnosed with chronic coccygodynia were randomly divided into two groups: the GIB group and the CESI group. The severity of pain, presence of neuropathic pain, and quality of life were evaluated using the Numeric Rating Scale, Leeds Assessment of the Neuropathic Symptoms and Signs Scale, and Short Form-12 Health Survey (SF-12), respectively. Results: A total of 34 patients in each group were included in the final analyses. While there was a significant decrease in pain intensity in both groups in the 3-month follow-up, this decrease was more significant in the GIB group at the 3rd week. There was a significant improvement in the SF-12 physical score and the number of patients with neuropathic pain in both groups in the 3rd week, but this improvement was not observed in the 3rd month. Conclusions: Although GIB may provide more pain relief in short term, both GIB and CESI are useful treatment methods in coccygodynia unresponsive to more conservative treatments.

Chloroma is a localized myeloblastic tumor which may develop during the course of myelogenous leukemia or as a presenting sign of the disease. A 47-year-old female diagnosed as chronic myelogenous leukemia in her hematologic remission period complained of left lower leg pain. The lumbar-spine series showed multiple osteolytic changes in the left lateral border of the lumbar spine. An inhomogenous soft tissue mass involving left lateral aspects of lumbar vertebrae was identified by CT-scanning. At the first pain attack, lumbar epidural steroid and local anesthetic injection could abolish her pain and the patient could go a few days without pain. The following radiation therapy could also improve the symptom and retain the pain free interval. One month later, a second pain attack occurred and lumbar and caudal epidural steroid and local anesthetic injections could result only in an incidental relief of pain. Radiation and chemotherapy were started but failed to relieve pain. A neurolytic block was considered but the patient's general condition was aggravated and even verbal communication with her became impossible.

Low back pain(LBP) is one of the most common ailment. There were two type of LBP in the clinic. One of them is low back pain with leg pain, the other one is low back pain without leg pain. Author explain the reasons, characters. mechanism, diagnosis, and reported 156 cases of LBP. There are various method to treatment of low back pain in recent. The first selection for treatment of LBP were intervertebral block added "+" type block(IVP "+" TB). according to author's experience, the rate of Excellent and good were account for 96.2%. Other method of LBPO therapy were also used in Pain clinic, such as psoas compartment block, caudal block, epidural steroid block, zygapophysial joint block, nerve root block, subarachnoid neural block, Lumbar sympathetic block, etc. Finally, author introduced Pain clinic in China. divided to three titles: (1) history, (2) CASP and scientific activity, (3) pain therapy in China.
