Introduction. Thoracic wall surgery can cause severe pain and inhibition of coughing with effects. (1) Various local anaesthetic (LA) techniques have been tried successfully to mitigate the use of opioids alone. We believe this is the first time that a serratus plane block using an epidural catheter (SABER)has been studied in anterior spinal fusion (ASF) procedures. Our aim was to ascertain how it would affect ASF compared to gold standard posterior spinal fusion (PSF) surgery. Materials and Methods. We identified 43 patients from the years 2017 to 2019. 24 had ASF and 19 had PSF. Detailed data were collected on local anaesthetic infusion (LAI) SaBER, mean pain scores(MPS), morphine, chirocaine usage and hospital length of stay (HLOS). We divided the patients into 4 groups: Short PSF (SPSF), Long PSF (LPSF), Thoracic anterior fusion (TA) and Thoracolumbar anterior fusion (TLA) surgery. 4 patients in the SPSF and 4 in the LPSF group had LAI because they had a costoplasty. All patients in the anterior group had SaBER. Results. Mean morphine usage was higher in the ASF group. Mean LA usage was lowest in the TLA and highest in the LPSF group (see table). 12 and 24 hour MPS were lower in both anterior groups compared to posterior. Mean HLOS was similar in all groups. Conclusion. Despite painful costoplasties in the anterior group, LAI enabled lower MPS overall and similar HLOS between PSF and ASF groups. Consequently, ASF (with fewer fusion levels) can replace equivalent PSF with resultant less stiffness and increased mobility. Reduction in MPS may be further improved by investigating detailed protocols whereby boluses of LA are given in addition to LAI. This may lead to morphine sparing in the anterior group as has been seen in other studies on thoracic wall procedures. (2). For any figures or tables, please contact the authors directly

Between 1986 and 1995, we treated with foraminal injection of local anaesthetic and steroids 30 patients with severe lumbar radiculopathy secondary to foraminal and extraforaminal disc herniation which had not resolved with rest and non-steroidal anti-inflammatory agents. They were assessed prospectively using standardised forms as well as the Low Back Outcome Score, and were reviewed at an average of 3.4 years (1 to 10) after injection by an independent observer (BKW). Relief of symptoms was obtained in 27 immediately after injection. Three subsequently relapsed, requiring operation, and two were lost to long-term follow-up. Thus 22 of the 28 patients available for long-term follow-up had considerable and sustained relief from their symptoms. Before the onset of symptoms 17 were in employment and, after injection, 13 resumed work, all but two in the same job. The average score before injection was 25 out of a possible 75 points. At follow-up, the overall average score was 54, and in those who had obtained relief of symptoms it had improved to a mean of 61. Based on these findings we recommend foraminal injection of local anaesthetic and steroids as the primary treatment for patients with severe radiculopathy secondary to foraminal or extraforaminal herniation of a lumbar disc

We have assessed whether an epidural steroid injection is effective in the treatment of symptoms due to compression of a nerve root in the lumbar spine by carrying out a prospective, randomised, controlled trial in which patients received either an epidural steroid injection or an intramuscular injection of local anaesthetic and steroid. We assessed a total of 93 patients according to the Oxford pain chart and the Oswestry disability index and followed up for a minimum of two years. All the patients had been categorised as potential candidates for surgery. There was a significant reduction in pain early on in those having an epidural steroid injection but no difference in the long term between the two groups. The rate of subsequent operation in the groups was similar

Background. Acute lumbar radiculopathy is a very painful condition sometimes requiring admission for strong analgesia. Purpose. To evaluate the efficacy of distal nerve root blocks as an outpatient procedure for immediate pain relief. Methods. Local anaesthetic was injected in the distal nerve root areas of the leg and foot in the clinic in patients with lumbar radiculopathy who consented to the procedure. Results. There were 29 patients, 18 females and 11 males, aged 25 to 76 years. 13 patients had acute lumbar disc prolapse, 11 had lumbar canal stenosis, 2 had annular tears and one a facet joint cyst. The VAS pain scores ranged from 3 to 11 (patient's description), with an average VAS score of 7.5. The improvement in VAS scores was between 2 and 9 with average improvement of 6. 19 patients had associated back pain which improved in 14. Walking improved in all 29 patients. Pain relief was immediate in all patients. This lasted from 30 min to 11 days with one patient having no recurrence. 27 patients had at least 24 hours pain relief. All patients could be sent home immediately after the procedure. 12 patients had recent onset of foot weakness which improved one MRC grade immediately after the injection. The analgesic effect was most significant in acute disc prolapse. There were no complications. Conclusion. This technique is simple and would be valuable in the acute setting to provide immediate pain relief allowing immediate discharge from accident and emergency. Conflicts of interest: None. Sources of funding: None

Background. Gore and Nadkarni described a ‘Gore sign’ of reproducing radiating leg pain by palpation of distal nerve root endings in the foot for L5 and S1 nerve roots in lumbar radiculopathy due to disc prolapse. Purpose. This sign was explored and observation of symptoms recorded. Results. There were 31 patients, 20 females and 11 males, aged 25 to 76 years. 13 patients had acute disc prolapse, 14 had lumbar canal stenosis, 3 had annular tears and one had a facet cyst. Radiating leg pain was reproduced in all patients by palpation of distal nerve root endings and was immediately relieved by local anaesthetic injection around distal nerve root endings in all patients (second part of Gore test). New clinical signs were observed which have not been described before:. Back pain was reproduced in 21 patients. L4 nerve root pain was reproduced in 13 patients by palpation of the proximal tibia. Crossed leg pain was reproduced in 5 patients. Reproduction of pain by palpation of more than one distal nerve root ending was observed in 16 patients. Cessation of radiating leg pain by palpation of distal nerve root endings in two patients. These test were positive in patients with varied pathology producing radiculopathy, not just disc prolapse. Conclusion. Provocative nerve root tension signs can be difficult in severe pain. The tests described above can be performed without having to move the patient's lower limb. These observations open up discussion on the mechanism of radiculopathy and new ways of treatment. Conflicts of interest: None. Sources of funding: None

Thoracic back pain caused by osteoarthritis of a single costovertebral joint is a poorly recognised condition. We report a series of five patients who were successfully treated by resection arthroplasty of this joint. Each had received a preliminary image-guided injection of local anaesthetic and steroid into the joint to confirm it as the source of pain. The surgical technique is described. There were no complications. The pain improved from a mean of 7.0 (6 to 8) on a visual analogue scale to 2.0 (0 to 4) post-operatively. The final post-operative Oswestry disability index was a mean of 19.4 (9 to 38). Isolated osteoarthritis of a costovertebral joint is a rare but treatable cause of thoracic back pain. It is possible to obtain excellent short- and intermediate-term relief from pain with resection arthroplasty in appropriately selected patients

We reviewed 15 consecutive patients, 11 women and four men, with a mean age of 48.7 years (37.3 to 62.6), who between July 2004 and August 2007 had undergone percutaneous sacroiliac fusion using hollow modular anchorage screws filled with demineralised bone matrix. Each patient was carefully assessed to exclude other conditions and underwent pre-operative CT and MR scans. The diagnosis of symptomatic sacroiliac disease was confirmed by an injection of local anaesthetic and steroid under image intensifier control. The short form-36 questionnaire and Majeed’s scoring system were used for pre- and post-operative functional evaluation. Post-operative radiological evaluation was performed using plain radiographs. Intra-operative blood loss was minimal and there were no post-operative clinical or radiological complications. The mean follow-up was for 17 months (9 to 39). The mean short form-36 scores improved from 37 (23 to 51) to 80 (67 to 92) for physical function and from 53 (34 to 73) to 86 (70 to 98) for general health (p = 0.037). The mean Majeed’s score improved from 37 (18 to 54) pre-operatively to 79 (63 to 96) post-operatively (p = 0.014). There were 13 good to excellent results. The remaining two patients improved in short form-36 from a mean of 29 (26 to 35) to 48 (44 to 52). Their persistent pain was probably due to concurrent lumbar pathology. We conclude that percutaneous hollow modular anchorage screws are a satisfactory method of achieving sacroiliac fusion

Background. NICE guidance suggests that caudal epidural injections of steroid and local anaesthetic may be considered for acute and severe sciatica, however studies have demonstrated limited long-term benefit and impact on future surgery. This study aimed to investigate the use of caudal epidural injections in a district general hospital setting and the rate of subsequent operation. Methods. All patients undergoing caudal epidural injection between 1. st. January and 30. th. June 2015 were included. Records were reviewed to obtain diagnosis, pre- and post-epidural clinical findings, prior interventions, and subsequent operations. Results. A total of 141 patients underwent a caudal epidural, with a median age of 63 (18 – 90). 37 patients went on to surgical intervention within 3 years, resulting in a conversion rate of 26.1%. Amongst those not requiring surgery, 59 (56.19%) had disc herniation, 42 (40%) stenosis, 4 spondylolisthesis, and 1 a facet cyst. Pre-operatively 63.81% reported back pain and 93.33% sciatica. 39.05% of patients had sensorimotor changes. Post-operatively, 27.62% reported an improvement in their back pain, compared to 62.86% reporting improved leg pain. 36.59% of those with sensorimotor changes reported improvement. 32 later had a further caudal epidural or foraminal block, and 25 had facet and sacroiliac joint injections. Amongst those requiring surgery, 21 (56.76%) had disc herniation, 15 (40.54%) stenosis, and 1 spondylolisthesis (2.7%). Conclusion. In our series, approximately three quarters of patients undergoing caudal epidural injection did not subsequently require surgery. Lumbosacral radicular symptoms improved in two thirds, however the epidural was less effective at treating back pain. No conflicts of interest. No funding obtained

Purpose:. To evaluate if adding clonidine to a standard nerve root block containing local anaesthetic and steroid improved the outcome of patients with severe lumbar nerve root pain secondary to MRI proven lumbar disc prolapse. Methods:. We undertook a single blind, prospective, randomised controlled trial evaluating 100 consecutive patients with nerve root pain secondary to lumbar disc prolapse undergoing trans-foraminal epidural steroid injection either with or without the addition of clonidine. 50 patients were allocated to each arm of the study. The primary outcome measure was the avoidance of a second procedure- repeat injection or micro-discectomy surgery. Secondary outcome measures were also studied: pain scores for leg and back pain using a visual analogue scale (VAS), the Roland Morris Disability Questionnaire (RMDQ) and the Measure Your Own Medical Outcome Profile (MYMOP). Follow up was carried out at 6 weeks, 6 months and 1 year. Results:. No serious complications occurred. Of the 50 patients who received the addition of clonidine, 56% were classified as successful injections, with no further intervention required, as opposed to 40% who received the standard injection. This difference did not reach statistical significance (p=0.109, chi-squared test). All secondary measures showed no statistically significant differences between the groups except curiously, the standard group who had been classified as successful had better leg pain relief than the clonidine group (p=0.026) at 1 year. Conclusions:. This pilot study has shown a 16% treatment effect with adding clonidine to lumbar nerve root blocks and that it is a safe injectate for this purpose

Introduction. Percutaneous radiofrequency lesioning of the lateral branches of the sacroiliac joint has become a recognised method of treating chronic pain arising from this joint. Due to the large and varied innervation from the S1-3 lateral branches success has been achieved with large lesions that has a high chance of covering these nerves. Such lesions require specialised and expensive equipment and the NIMBUS needle is a large 17G electrode with expandable tines at the tip. It is compatible with all standard radiofrequency probes and it produces a large lesion at the tip. It has been in use in the USA in over 100 cases and we describe its use in the UK. Methods. Patients were identified as having sacroiliac joint pain by clinical assessment and positive pain response to local anaesthetic sacroiliac joint lateral branch blocks. Under fluoroscopic control, the needle is inserted at the lateral edge of the sacral S1-3 posterior foramen. Three lesions at the lateral edge of the foramen are made at 80°C for 90s. A further lesion is made at the L5 dorsal ramus. Results. 4 patients achieved very good pain relief >50% reduction in pain scores on the NRS scale at 6 weeks follow up. No complications were noted and there were no technical difficulties. Conclusion. Lesioning with the NIMBUS needle is feasible and allows clinicians a method of treating chronic sacroiliac joint pain using existing radiofrequency equipment. Further large, long term studies are warranted to establish clinical efficacy

To analyse procedural details - specifically vertebral levels treated and injected polymethylmethacrylate (PMMA) volumes - of the publications by Buchbinder et al. . 1. and Kallmes et al. . 2. in the context of best available basic science. Review. Two randomised controlled trials published by the New England Journal of Medicine (NEJM) in 2009 comparing vertebroplasty to sham procedures conclude vertebroplasty to be no more effective than injection of local anaesthetic. This finding contradicts previous publications showing clinical efficacy. Neither investigation provides a breakdown of vertebral levels treated (original publication and supplementary material). Only one investigation provides information on fill volumes with average of 2.8 ml +/− 1.2 ml SD. The available basic science indicates a minimum fill volume of 13-16% of the vertebral body volume to be necessary for a relevant biomechanical effect on restoration of vertebral strength, according to which only vertebrae of the upper to mid thoracic spine could reasonably have received a biomechanically effective fill with the declared average volume of 2.8 ml +/− 1.2 ml SD. The available data of the NEJM publications strongly indicates that the treatment arm includes insufficiently treated patients. The technical information provided by the NEJM publications is insufficient to conclusively prove or disprove the clinical efficacy of vertebroplasty

The use of nerve root blocks is common in the management of radicular pain due to lumbar disc prolapse. However, most papers reporting their use do not necessarily specify the position or level at which the needle is positioned with respect to the level of pathology. We therefore set out to investigate this. We performed a survey of medical practitioners across the UK with an interest or involvement in the management of radicular pain secondary to lumbar disc prolapse The survey depicted the clinical scenario of a patient with radicular pain from an L4/5 disc prolapse and a number of questions were asked in relation to the use of nerve root blocks. Questionnaires were sent to 319 practitioners. We received 153 responses of which, 120 (37.6%) were sufficiently complete to be analysed. Of those who responded, 83% used a combination of local anaesthetic and steroids together with or without contrast. There were variations across the respondents in terms of the level injected with 22.5% injecting at the level of the L4/5 foramen, while 45% injected at the level of the L5/1 foramen. Differences were also noted when respondents were subgrouped according to their speciality. Of those who worked in pain management, 34.1% injected at the L4/5 foramen while 31.8% injected at the L5/1 foramen. For spine surgeons the respective figures were 20.5% and 43.2% and for radiologists 9.4% and 65.6%. In the treatment of radicular leg pain, there are apparent variations in the use and positioning of root blocks for a given level of disc pathology. This suggests that caution is necessary when considering the validity of published studies on the use of root blocks relative to an individual clinician's practice

Objective. Our aim is to assess the use of the cervical nerve root block (CNRB) in the treatment of radicular pain associated with degenerative cervical spine disease and its potential to limit the need for surgical intervention. Methods. A retrospective review of consecutive CNRB procedures carried out between January 2008 and June 2010. All procedures were performed using a combination of local anaesthetic and steroid under fluoroscopic guidance. The inclusion criteria were brachialgia with MRI proven nerve compression and inadequate response to physiotherapy. Patients that underwent both a CNRB and facet joint injections were excluded. The outcome measures assessed were the response gained (complete/temporary/no relief) and the choice of further management. Results. A total of 121 patients underwent CNRBs within our study period. 11 patients were lost to follow up. A cohort of 110 patients was studied (49 male and 61 female) with a mean age of 51.5 years (standard deviation 12.3 years). Following the initial CNRB, 49 patients (44.5%) had complete relief requiring no further interventions. Temporary symptom relief was achieved for 30 patients (27.3%) and no relief was gained in 31 patients (31.2%). A repeat CNRB was carried out in 19 patients who gained temporary or no benefit following the initial block. Of the 97 patients who have a complete follow up, complete resolution of symptoms was achieved in 53 patients (54.6%), 25 patients (25.8%) progressed to requiring surgery and no further treatment was offered to 19 patients (19.6%). No complications related to the procedure were identified. Conclusion. Cervical nerve root blocks can be performed to treat patients suffering with cervical radiculopathy symptoms. It is a minimally invasive intervention that can reduce the need for operative intervention

Purpose of Study. To review the medium-term results of the Dynesys stabilisation system used in 113 consecutive patients with discogenic back pain. Methods and Results. 113 consecutive patients with discogenic back pain were treated with Dynesys as the sole intervention. Inclusion criteria included mri proven disc degeneration and an improvement in symptoms following an injection into the disc with local anaesthetic and steroid (spinal disc probing). Patients were followed up for a minimum of 5 years, with outcome measures including SF-36, Oswestry disability index (ODI) and visual pain analogue scores (VPAS). Additional factors reviewed included previous spinal operations, complications, loosening and revision rates with subsequent outcomes. Mean pre-operative ODI was 49.5, SF-36 was 37.6 and VPAS back pain was 60.9. At one year post operatively, these scores were 36.9, 49.4 and 39.8, at five years follow up, the scores were 33.3, 51.8 and 40.1 respectively. We note wide variations in our results. Several significant factors appear to contribute to the outcome of surgery. These include undergoing surgery before the age of 43, no more than 2-level disc degeneration, leg pain less than VPAS 4, and no previous spinal surgery. 19 patients had screw loosening evident on plain film x-rays (4 requiring removal), and 2 patients had screw breakages. 19 patients had implant removal for failure and 2 patients went on to have a fusion procedure. Discussion. Dynesys has a role in the treatment of discogenic back pain. Patient selection is important to outcome and we have identified several pre-operative factors that increase the likelihood of success. The effects are present at 1 year postoperatively and are maintained for at least 5 years. There is a significant screw loosening rate and our series had a 17% revision rate

Aims

We aimed to establish the short- and long-term efficacy of corticosteroid injection for coccydynia, and to determine if betamethasone or triamcinolone has the best effect.

Aims

The aims of this study were to determine the diagnostic yield of image-guided biopsy in providing a final diagnosis in patients with suspected infectious spondylodiscitis, to report the diagnostic accuracy of various microbiological tests and histological examinations in these patients, and to report the epidemiology of infectious spondylodiscitis from a country where tuberculosis (TB) is endemic, including the incidence of drug-resistant TB.

The National Institute for Health and Care Excellence has issued guidelines that state fusion for non-specific low back pain should only be performed as part of a randomised controlled trial, and that lumbar disc replacement should not be performed. Thus, spinal fusion and disc replacement will no longer be routine forms of treatment for patients with low back pain. This annotation considers the evidence upon which these guidelines are based.

Vertebral compression fractures are the most prevalent complication of osteoporosis and percutaneous vertebroplasty (PVP) has emerged as a promising addition to the methods of treating the debilitating pain they may cause.

Since PVP was first reported in the literature in 1987, more than 600 clinical papers have been published on the subject. Most report excellent improvements in pain relief and quality of life. However, these papers have been based mostly on uncontrolled cohort studies with a wide variety of inclusion and exclusion criteria. In 2009, two high-profile randomised controlled trials were published in the New England Journal of Medicine which led care providers throughout the world to question the value of PVP. After more than two decades a number of important questions about the mechanism and the effectiveness of this procedure remain unanswered.

Aims

The aim of this study was to compare the effect of a percutaneous radiofrequency heat lesion at the medial branch of the primary dorsal ramus with a sham procedure, for the treatment of lumbar facet joint pain.

Between 1993 and 2008, 41 patients underwent total coccygectomy for coccydynia which had failed to respond to six months of conservative management. Of these, 40 patients were available for clinical review and 39 completed a questionnaire giving their evaluation of the effect of the operation. Excellent or good results were obtained in 33 of the 41 patients, comprising 18 of the 21 patients with coccydynia due to trauma, five of the eight patients with symptoms following childbirth and ten of 12 idiopathic onset. In eight patients the results were moderate or poor, although none described worse pain after the operation. The only post-operative complication was superficial wound infection which occurred in five patients and which settled fully with antibiotic treatment. One patient required re-operation for excision of the distal cornua of the sacrum.

Total coccygectomy offered satisfactory relief of pain in the majority of patients regardless of the cause of their symptoms.
