ABSTRACT

This paper reports a case of a patient aged 63 years who developed a delayed pneumothorax after thoracic paravertebral block (TPVB). TPVB is a non-invasive procedure that is known to be relatively safe. A 63-year-old female was admitted with back pain. TPVB T9–10 left was then performed. Two days after the procedure, she complained of dyspnea in the emergency room. X-ray showed a pneumothorax in her left side with partial left lung collapse. The pneumothorax was managed by surgical intervention, and an intercostal tube was inserted. The post-procedural X-ray showed a fully expanded lung. A chest tube was taken out after 72 hours. A delayed pneumothorax can occur after TPVB. Therefore, careful observation is required after this procedure.

ABSTRACT

PURPOSE@#This paper compares the clinical outcomes of patients who were treated with a cervical nerve block by ultrasound and C-arm and reports the complication.@*MATERIALS AND METHODS@#A total of 97 patients were treated with an ultrasound-guided nerve root block from May 1, 2015 to February 8, 2018. On the other hand, 94 patients were treated with a C-arm guided nerve root block. The consequences of the cervical pain and the radiating pain before and after the procedures were reviewed using the verbal numeric rating scale (VNRS). In addition, the complications related to the procedures from the daily notes from the chart were inspected.@*RESULTS@#Sixty-six cases out of 97 cases of ultrasound-guided nerve root block were enrolled in the study. The average age of the patients was 57 years, including 41 males and 25 females. Seventy seven out of 94 cases by a C-arm guided root block were included in the study. The average age of the patients was 55 years, including 40 males and 37 females. Before the nerve root block, the mean numeric rating pain scale (NRS) of the cervical pain in ultrasound-guided block decreased from 5.4 points to 2.7 points at three weeks and 1.4 points at six weeks (p=0.0023, p<0.001), and 3.1 points in the C-arm (p<0.001, p<0.001) at three weeks and 1.5 points at six weeks (p<0.001, p<0.001). In the case of radiating pain, the mean NRS in the ultrasound-guided nerve root block group improved from 6.3 points after the procedure to 2.8 points at three weeks and 1.5 points at six weeks (p<0.001, p<0.001). In the C-arm guided nerve root block group, the NRS improved from 7.4 points after the procedure to 3.3 points at three weeks and 1.9 points at six weeks. In the case of complications, Horner's syndrome and propriospinal myoclonus were observed in one case of C-arm guided block group.@*CONCLUSION@#The clinical results of the patients who underwent ultrasound-guided cervical nerve root block were not significantly different from those who underwent a C-arm guided cervical nerve root block.

ABSTRACT

Purpose@#This study examined the utility of preliminary magnetic resonance imaging (MRI) measurements in the ultrasound-guided L4 selective nerve root block. @*Materials and Methods@#As a retrospective study, 71 patients, who met the criteria for outpatient visits from March 2016 to December 2017, were included. From March 2016 to February 2017, 31 patients who underwent an L4 nerve root block without MRI were classified as group A, and 40 patients who underwent an L4 nerve root block through MRI measurements from March 2017 to December 2017 were classified as group B. Group A was injected under ultrasound-guidance through the pararadicular approach without a pre-interventional MRI evaluation, and group B was injected under ultrasound-guidance according to the preliminary MRI measurements. The results were assessed using the numeric rating scale scores before, three hours, and two, six, and 12 weeks after the procedure. @*Results@#At three hours after the procedure, the proportion of patients better than good results were 51.6% in group A and 67.5% in group B. At two weeks after the procedure, the proportion of patients with better than good results were 48.4% and 70.0% in groups A and B, respectively; 58.1% and 62.5% of patient of groups A and B, respectively, showed better than good results after six weeks. In 12 weeks after the procedure, the results of group A and B were 67.7% and 62.5%, respectively. At three hours and two weeks after the procedure, group B showed significant symptom improvement than group A (p<0.05). The procedures were repeated 2.8 and 1.7 times in groups A and B, respectively, between two and six weeks for satisfactory pain relief (p<0.05). @*Conclusion@#A pre-interventional MRI evaluation might improve pain relief within the initial two weeks after ultrasound-guided L4 selective nerve root block by improving the success rate of the procedure.

ABSTRACT

Objectives@#This study analyzed the diagnostic and therapeutic usefulness of selective nerve root block (SNRB) in patients with spinal stenosis who show inconsistencies between magnetic resonance imaging (MRI) and clinical findings (e.g., dermatomes).Summary of Literature Review: MRI is known to be highly accurate for diagnosing spinal stenosis, but few studies have investigated the diagnostic accuracy of MRI for spinal canal stenosis. In addition, the most suitable treatment of patients with inconsistent clinical and MRI findings has not been established. @*Methods@#This single-center, retrospective cohort study was conducted among 93 patients treated between January 2013 and December 2018, who underwent at least two SNRBs for single-level spinal stenosis on MRI with clinical discrepancies. Seventeen patients who were diagnosed with other causes of pain (e.g., spondylolisthesis, sacroiliac joint dysfunction, lower leg arterial occlusion) were excluded. The first SNRB targeted the lesion found on MRI. One week later, patients were assessed using a visual analog scale (VAS) and a second procedure was performed on the dermatome-indicated level if there was no improvement. VAS scores were also obtained 3 months after the procedure. @*Results@#In total, 45 patients had central stenosis and 31 patients had foraminal stenosis. The average VAS score before the SNRB was 7.4±1.4. After the first procedure, the average VAS score was 5.2±2.6. After the second procedure, the average VAS score was 2.4±1.3, and after 3 months, it was 3.6±1.9. Of the patients with foraminal stenosis, 77.4% did not respond to the first block (based on MRI), but responded well to the second procedure (based on clinical symptoms) (p<0.05). @*Conclusions@#SNRB targeting the level corresponding to clinical symptoms may be useful for locating the symptomatic nerve root and providing pain relief in patients with foraminal stenosis on MRI with discordant clinical findings.

ABSTRACT

Background@#Surgical treatment consisting of decompression and fusion is generally known to produce good clinical results for lumbar spinal stenosis with degenerative spondylolisthesis. However, the clinical outcome of decompression alone, without fusion, remains unclear, and long-term follow-up results are scarce. This study aimed to retrospectively analyze the 5-year clinical results of decompression only in patients with lumbar spinal stenosis and degenerative spondylolisthesis. @*Methods@#Among the patients diagnosed as having lumbar spinal stenosis with degenerative spondylolisthesis, 36 patients who underwent decompression without fusion and were followed up for minimum 5 years were included in this study. The average follow-up period was 7.2 years, and the mean age of patients was 63.2 years. Visual analog scale (VAS) score and Oswestry disability index (ODI) were investigated pre- and postoperatively, and also radiologic displacement and instability were measured. In addition, patients who needed fusion or redecompression at the decompression site postoperatively were also investigated. @*Results@#VAS score and ODI improved from an average of 7.8 points and 57 points preoperatively, respectively, to 1.4 points and 19 points at 5 years postoperatively, respectively. The degree of radiologic displacement increased from an average of 5.1 mm preoperatively to 6.4 mm at the final follow-up. Radiological instability was detected in five patients. Two patients (9.5%) required fusion. @*Conclusions@#The long-term follow-up results revealed that satisfactory clinical outcomes were obtained with decompression alone, without fusion, for patients with lumbar spinal stenosis and degenerative spondylolisthesis.

ABSTRACT

Background@#Biportal endoscopic unilateral laminectomy for bilateral decompression (ULBD) is an emerging minimally invasive procedure for spinal stenosis. However, reports of the results associated with this surgical method are still lacking. @*Methods@#We conducted a retrospective study of 60 patients who underwent bilateral decompression for lumbar central canal stenosis. The patients were divided into 2 groups according to the surgical method (endoscopic ULBD vs. microscopic ULBD). We compared the outcomes between the 2 groups in terms of postoperative segmental spinal instability, dura expansion, operation time, estimated blood loss, serum creatine kinase (CK), serum C-reactive protein (CRP), visual analog scale (VAS) score, Oswestry Disability Index (ODI), modified MacNab score, and the incidence of complications. @*Results@#The mean VAS, ODI, and modified MacNab score improved significantly from the preoperative period to the last follow-up in both groups and were better in the endoscopic ULBD group until the first day after treatment. The degree of horizontal displacement was lower in the endoscopic ULBD group than in the microscopic ULBD group at postoperative 12 months. Dura expansion, operation time, and estimated blood loss did not differ significantly between the 2 groups. Serum CK and CRP on the first day after treatment were lower in the endoscopic ULBD group than in the microscopic ULBD group. @*Conclusions@#This study shows that both endoscopic ULBD and microscopic ULBD can provide favorable outcomes for lumbar central canal stenosis. However, compared to microscopic ULBD, endoscopic ULBD has advantages in terms of postoperative segmental spinal instability, pain control, and serum CK and CRP.

ABSTRACT

OBJECTIVES@#This study was conducted to evaluate the effects of using an epidural steroid sponge for postoperative pain control in lumbar discectomy.SUMMARY OF LITERATURE REVIEW: There are many methods to control postoperative pain after lumbar discectomy, including opioid analgesics, epidural catheters, and epidural steroid Gelfoam sponges.@*MATERIALS AND METHODS@#A total of 72 patients who underwent surgery between March 2011 and February 2014 were enrolled. Their average age was 54 years (range, 24–82 years). In group A (35 patients), Gelfoam was inserted after being soaked with a solution of 2% lidocaine (400 mg/20 mL; 1 vial) and dexamethasone (5 mg/mL; 1 ampoule). In group B (37 patients), it was inserted after soaking with normal saline. Postoperative pain was assessed by visual analogue scale (VAS) scores. Pain above 5 points was controlled by a narcotic analgesic agent, and the duration and number of postoperative interventions, the period of time before walking after the operation, and the period until the date of discharge after surgery were assessed and compared. The Mann-Whitney U test was used as a nonparametric method. P-values less than 0.05 were considered to indicate statistical significance.@*RESULTS@#In group A, 15 patients did not require analgesics on the day of surgery. In 20 patients, no analgesics were needed on postoperative day (POD) 1. In group B, 8 patients on the day of surgery and 13 patients on POD 1 did not require analgesics. In group A, 26 patients were able to walk on the day of surgery, and all patients were able to walk on POD 1. In group B, 19 patients was able to walk on the day of surgery and all patients were able to walk on POD 1. The mean number of hospital days before discharge was 6.3 in group A and 8.2 in group B.@*CONCLUSIONS@#By continuously releasing low doses of steroids into the epidural space, this technique provided satisfactory results for postoperative pain control.

ABSTRACT

BACKGROUND: Buttock pain is common, and there are no fixed guidelines for its diagnosis and treatment. This study compared a selective nerve root block and a facet joint block for patients with degenerative spinal disease and buttock pain. METHODS: Patients with degenerative spinal disease who presented with buttock pain, received a selective nerve root block (group A) or a facet joint block (group B) from June 2017 to September 2017, and were able to be followed up for more than 3 months were prospectively enrolled. Clinical results were assessed using a visual analog scale for comparative analysis. RESULTS: One day after the procedure, an excellent response was found in 7% and 6% of groups A and B, respectively; a good response was found in 41% and 13% of groups A and B, respectively. Two weeks later, an excellent response was found in 11% and 4% of groups A and B, respectively; a good response was found in 41% and 20% of groups A and B, respectively. Six weeks later, an excellent response was found in 11% and 7% of groups A and B, respectively, and a good response was found in 41% and 20% of groups A and B, respectively. At the final follow-up, more than 47% and 46% of patients showed a good response in groups A and B, respectively. In group A, the visual analog scale score improved compared to the pre-procedure value of 5.01 to 2.74 on day 1, 2.51 at week 2, 2.38 at week 6, and 2.39 at week 12. In group B, the visual analog scale score improved compared to the preprocedure value of 5.24 to 3.94 on day 1, 3.99 at week 2, 3.24 at week 6, and 2.59 at week 12. On day 1 and at weeks 2 and 6, group A showed a significantly better outcome than group B (p < 0.05). CONCLUSIONS: The selective nerve root block showed superior results up to 6 weeks post-procedure. Considering that the selective nerve root block is effective for treating radiculopathy, the primary cause of buttock pain can be thought to be radiculopathy rather than degenerative changes of the facet joint.

ABSTRACT

OBJECTIVES@#We analyzed the radiological results of the double-balloon inflation technique in terms of its ability to reduce cement leakage, to increase bone cement bonding, and to promote anterior column height recovery.SUMMARY OF LITERATURE REVIEW: Various methods, such as the egg-shell technique, have been proposed to prevent leakage of cement during kyphoplasty in cases of osteoporotic compression fracture.@*MATERIALS AND METHODS@#This study analyzed 18 patients diagnosed with osteoporotic compression fracture of the lumbar spine who underwent the double-balloon inflation technique after April 2015, and 30 consecutive patients with the same diagnosis who were treated using the conventional method prior to April 2015. We analyzed the radiological results on immediate postoperative simple X-rays in the anteroposterior and lateral views, 6-week postoperative lateral X-rays, and 6-month postoperative lateral X-rays to detect changes in anterior vertebral height and the cement leakage rate.@*RESULTS@#The average anterior vertebral height increased by 7.58 mm in the double-balloon inflation group, and by 5.8 mm in the conventional group on the immediate postoperative radiographs (p=0.044). On average, a decrease of 3.08 mm was observed at 6 weeks postoperatively in the double-balloon inflation group, in contrast to a decrease of 4.68 mm in the conventional group (p=0.149). At the 6-month postoperative follow-up, an average decrease of 1.45 mm was found in the double-balloon inflation technique group, while a decrease of 1.40 mm was found in the conventional group (p=0.9110). The cement leakage rate was 22% in the double-balloon inflation group and 27% in the conventional group (p=0.730).@*CONCLUSIONS@#Compared to the conventional method, the double-balloon inflation technique can be done more safely, and also promotes a greater recovery of anterior vertebral height.

ABSTRACT

Munchausen syndrome is a rare factitious disorder in which a person repeatedly and deliberately acts as if he or she has a physical or mental illness when he or she is not really sick. These patients distort their medical history, undergoing dangerous diagnostic and therapeutic procedures, often resulting in misdiagnosis. Management of this syndrome requires collateral history taking, sound clinical approach, exclusion of organicity, and addressing psychological issues. We report a 54-year-old female, who underwent orthopedic surgery 13 times. She was always unsatisfied with her surgical outcomes, and underwent additional surgical treatment of the shoulder, elbow, wrist, and knee joint. She repeatedly complained of joint pain, which was much more exaggerated than expected from her examination results. Therefore, we considered artificial arthrosis for a differential diagnosis of unclear arthrosis, and paid special attention when she exhibited odd behaviors.

ABSTRACT

This paper reviews previous studies on the treatment of osteoporotic vertebral compression fractures in elderly patients to determine what factors should be considered for successful treatment. In osteoporotic vertebral compression fractures, the primary treatment is conservative treatments. Other treatments include osteoporosis treatment, pain control, orthosis, and physical therapy. Recently, percutaneous catheterization or balloon plasty is performed for rapid pain recovery and early ambulation. Percutaneous catheterization or balloon posterior plasty is effective in reducing pain and improving the activity ability. Surgical treatment should be considered in cases of nonunion or osteonecrosis, dent, deformation, and spinal cord compression after conservative treatment has failed. In surgical treatment, posterior spinal fixation and vertebroplasty are more advantageous in terms of the amount of bleeding, operation time compared to the anterior approach, but the most appropriate method should be selected through the patient's condition and understanding of each surgical method.

ABSTRACT

PURPOSE: To retrospectively evaluate the improvement of symptoms and diagnosis using selective nerve root block (SNRB) for radiating pain after spine surgery. MATERIALS AND METHODS: From October 2012 to October 2013, 112 patients with failed back surgery syndrome (41 male and 71 female, with the mean age of 62.4 years and range of 35 to 78 years), who were admitted and underwent SNRB, were included. All patients were followed-up for more than 12 months. Three groups were classified: Group 1 included patients with no improvement or aggravation of symptoms, group 2 included those with improvement of radiating pain, and group 3 included those with recurrence of radiating. RESULTS: Among the 112 patients, there were 15 patients in group 1, 59 patients in group 2, and 38 patients in group 3. Laminectomy was the highest surgical procedure, inducing failed back surgery syndrome. In group 2, the occurrence of failed back surgery syndrome was higher in case that radiating pain was complained more than 1 year before the first surgery. There is statistically significant symptom improvement in accordance with the visual analogue scale and Korean version of Oswestry disability index on every group after SNRB (p<0.05). CONCLUSION: It is considered that SNRB is expected to improve the symptoms and to find the cause of symptoms as a diagnostic value even after spine surgery.

ABSTRACT

PURPOSE: We reported relative risk of operation between patients who were diagnosed with lumbar far lateral disc herniation and posterolateral disc herniation after transforaminal epidural block. MATERIALS AND METHODS: A retrospective cohort study was performed on 295 patients (131 male and 164 female) who underwent transforaminal epidural block for unilateral radiculopathy caused by lumbar intervertebral disc herniation. Among these 295 patients, 34 patients were diagnosed with far lateral disc herniation and 261 patients with posterolateral disc herniation. The median follow-up period was 23.9 months, with an average age of 55.7 years. RESULTS: Fifty-one patients underwent surgical treatment. Among them, 38 patients had posterolateral disc herniation and 13 patients had far lateral disc herniation. Patients with far lateral disc herniation, when compared with posterolateral disc herniation, had a relative risk of operation of 2.67 (1.59-4.48, 95% confidence interval) with statistical significance (p=0.0002). At the final follow-up, the average visual analogue scale (VAS) score for radicular pain in the surgical and non-surgical groups was 0.69 and 1.50, respectively; the average Korean-Oswestry Disability Questionnaire (K-ODI) score was 11.7 and 9.6, respectively. The difference of average VAS score showed a statistical significance (p=0.035), however, that of K-ODI showed no statistical significance (p=0.266). CONCLUSION: In the case of far lateral disc herniation, the relative risk of surgery after transforaminal epidural block was 2.67, which is higher than that of posterolateral disc herniation. Therefore, we should consider surgical treatment more aggressively.

ABSTRACT

STUDY DESIGN: Retrospective clinical study. OBJECTIVES: To determine and compare the therapeutic effectiveness of selective nerve root block performed for single-segment spinal stenosis and disc herniation. SUMMARY OF LITERATURE REVIEW: The usefulness of selective nerve root block has been reported in several previous studies, but those results were aggregated across many diseases, making it difficult to estimate its effectiveness for each disease. MATERIALS AND METHODS: From January 2008 to January 2013, among patients who had undergone selective nerve root block, those who were diagnosed with single-segment spinal stenosis or disc herniation were enrolled in this study. Among a total of 103 patients, 47 spinal stenosis patients were classified as group 1, and 56 disc herniation patients as group 2. Visual analog scale (VAS) scores and Kim's criteria were used to compare the reductions in radiating pain in each group. RESULTS: In group 1, the VAS scores improved from 7.6 before the procedure to 2.6 and 3.3 at 1-month and 6-month follow-up visits, respectively. Kim's criteria also improved from a mean of 1.6 before the procedure to 2.9 at the 6-month follow-up. In group 2, the VAS scores improved from 7.8 before the procedure to 2.1 and 2.7 at 1-month and 6-month follow-up visits, respectively. Kim's criteria also improved from a mean of 1.8 before the procedure to 3.2 at the 6-month follow-up. CONCLUSIONS: Radiating pain in the lower limb due to spinal stenosis or disc herniation limited to a single segment was effectively controlled by selective nerve root block.

ABSTRACT

PURPOSE: The purpose of this study was to compare magnetic resonance imaging (MRI) and ultrasonography measurement of peri-lumbar muscle atrophy which is thought to be a cause of low back pain. MATERIALS AND METHODS: Eighty-two patients (44 males, 38 females) who visited Wonkang University Hospital from March, 2015 to August, 2015 complaining of lumbar back pain and underwent lumbar MRI were enrolled in this study. Cross section area (CSAMRI) and muscle thickness (MTMRI) of psoas major (PS) and lumbar extensor (LM) located on both sides of L4/5 and L3/4 was measured by MRI, and sono measurement of thickness of the same muscle (MTUS) at the same level of that MRI measurement were analyzed. RESULTS: In correlation analysis of PS CSAMRI and PS MTUS is the correlation coefficient of L4/5 was 0.136 (p=0.64), L3/4 right (Rt) was 0.070 (p=0.81), and L3/4 left (Lt) was 0.288 (p=0.32). PS CSAMRI at L4/5 Rt showed that correlation coefficient of PS MTUS showed a positive correlation to 0.559 (p=0.04). In analysis of the PS MTMRI and PS MTUS, the correlation coefficient of L4/5 Rt was measured by a 0.316 (p=0.27), L4/5 Lt was 0.022 (p=0.94), L3/4 Rt was 0.236 (p=0.41), and L3/4 Lt did not show a significant result with 0.287 (p=0.31). In the results of correlation analysis of the LM MTMRI and LM MTUS, the correlation coefficient of L4/5 Rt was 0.207 (p=0.49), L4/5 Lt was 0.051 (p=0.86), and L3/4 was Rt 0.048 (p=0.87), L3/4 Lt did not show a significant value with 0.154 (p=0.61). CONCLUSION: This study proved that muscle volume obtained from ultrasono is effective for evaluation of cross-sectional area of lumbar muscle.
