Project description:Purpose:To determine the association between preoperative lumbar epidural injections (LEIs) in the operating theater (OR) and the occurrence of surgical site infection (SSI) after posterior lumbar instrumented fusion surgery. Methods:This study was performed from January 2015 to September 2019. We enrolled 2312 patients who underwent lumbar surgery without LEIs (control group) and 469 patients who underwent lumbar surgery after LEIs in the OR. We further separated the patients by the time interval between the LEIs and surgery: 1) for the 0-1 M group, lumbar surgery was performed within 1 month after the LEIs, and 2) for the >1 M group, it was performed more than 1 month after the LEIs. Results:The postoperative infection rate in the 0-1 M group was considerably higher than that in the control group (p = 0.0101). We further subdivided the 0-1 M and >1 M groups into four subgroups: a) the 0-1 MNS group included patients in the 0-1 M group who did not receive steroids; b) the 0-1 MS group who received steroids; c) the >1 MNS group included patients in the >1 M group who did not receive steroids; d) the >1 MS group who received steroids. The postoperative infection rate in the 0-1 MS subgroup was considerably higher than that in the control group (p = 0.0018). However, the infection rate was lower in the >1 MS subgroup (p = 0.1650). There were no statistically significant differences in the postoperative infection rate between the control group and the two non-steroid groups (0-1 MNS group, p = 0.4961; 1 MNS group, p = 0.7381). Conclusion:The administration of LEIs without steroids in the OR before lumbar instrumented fusion does not significantly increase patients' risk of postoperative infection. We recommend avoiding steroid injections administered within 1 month before lumbar instrumented fusion.

Project description:BACKGROUND:The aim of this study was to evaluate satisfaction and factors associated with satisfaction in elderly undergoing lumbar disc herniation surgery. METHODS:In the national Swedish register for spinal surgery (SweSpine) we identified 2095 patients aged >?65?years (WHO definition of elderly) whom during 2000-2016 had undergone LDH surgery and had pre- and one-year postoperative data (age, gender, preoperative duration and degree of back- and leg pain, quality of life (SF-36) and one-year satisfaction (dissatisfied, uncertain, satisfied). We utilized a logistic regression model to examine preoperative factors that were independently associated with low and high satisfaction and after LDH surgery. RESULTS:One year after surgery, 71% of the patients were satisfied, 18% uncertain and 11% dissatisfied. Patients who were satisfied were in comparison to others, younger, had shorter preoperative duration of leg pain, higher SF-36 mental component summary and more leg than back pain (all p?<?0.01). Patients who were dissatisfied were compared to others older, had longer preoperative duration of leg pain and lower SF-36 scores (all p?<?0.01). 81% of patients with leg pain up to 3?months were satisfied in comparison with 57% of patients with leg pain >?2?years (p?<?0.001). CONCLUSION:Only one out of ten elderly, is dissatisfied with the outcome of LDH surgery. Age, preoperative duration of leg pain, preoperative SF 36 score, and for satisfaction also dominance of back over leg pain, are in elderly factors associated to good and poor subjective outcome after LDH surgery.

Project description:BackgroundProlonged sciatica symptoms may result in disability and consequently, absence from work for a longer period. Up to 10% of patients may need surgery but it is difficult to predict and determine which of these patients would improve spontaneously in comparison to those who might benefit from discectomy surgery. We aimed to determine if delay in the "time to surgery" (TTS) has any adverse effects on the patient reported outcome measures (PROMs).MethodsEighty-seven patients after exclusions were selected consecutively. PROMs were comprised of pre-operative, six weeks and six months post-operative back and leg pain visual analogue scores (VAS) and Oswestry disability index (ODI). The differences between these scores were correlated with TTS. Minimal clinically important difference (MCID) of 30% improvement for ODI scores and 33% for VAS scores from baseline were considered as significant improvement. Patients were grouped into TTS less than 6 months and TTS greater than 6 months from referral to TTS. The longest TTS was 18 months. Statistical analysis was done using JASP (Version 0.14.0) [computer software].ResultsThe TTS was on average 22.5 weeks. MCID for the leg pain VAS was achieved in 90.2% patients with TTS <6 months and in 80.8% with TTS ≥6 months. The MCID for ODI was achieved in 60.7% with TTS <6 months and in 42.0% with TTS ≥6 months. The MCID for back pain VAS was achieved in 73.8% with TTS <6 months and in 50.0% of patients with TTS ≥6 months. Those who achieved the MCID in ODI score between the two groups were analysed using chi-square test with P=0.115. Those who achieved the MCID in VAS leg pain score between the two groups were analysed using chi-square test with P=0.227. No statistical difference was found in ODI and VAS for leg for patients with TTS before or after 6 months.ConclusionsLumbar discectomies had a positive impact on patient's pain and function in our local district hospital. Delayed surgery of ≥6 months did not cause statistically significant worse outcomes. In the absence of worsening neurological deficit, it may be the wrong approach to define a value for the TTS.

Project description:As part of a comprehensive nonsurgical approach, epidural injections often are used in the management of lumbar disc herniation. Recent guidelines and systematic reviews have reached different conclusions about the efficacy of epidural injections in managing lumbar disc herniation.In this systematic review, we determined the efficacy (pain relief and functional improvement) of the three anatomic approaches (caudal, lumbar interlaminar, and transforaminal) for epidural injections in the treatment of disc herniation.We performed a literature search from 1966 to June 2013 in PubMed, Cochrane library, US National Guideline Clearinghouse, previous systematic reviews, and cross-references for trials studying all types of epidural injections in managing chronic or chronic and subacute lumbar disc herniation. We wanted only randomized controlled trials (RCTs) (either placebo or active controlled) to be included in our analysis, and 66 studies found in our search fulfilled these criteria. We then assessed the methodologic quality of these 66 studies using the Cochrane review criteria for RCTs. Thirty-nine studies were excluded, leaving 23 RCTs of high and moderate methodologic quality for analysis. Evidence for the efficacy of all three approaches for epidural injection under fluoroscopy was strong for short-term (< 6 months) and moderate for long-term (? 6 months) based on the Cochrane rating system with five levels of evidence (best evidence synthesis), with strong evidence denoting consistent findings among multiple high-quality RCTs and moderate evidence denoting consistent findings among multiple low-quality RCTs or one high-quality RCT. The primary outcome measure was pain relief, defined as at least 50% improvement in pain or 3-point improvement in pain scores in at least 50% of the patients. The secondary outcome measure was functional improvement, defined as 50% reduction in disability or 30% reduction in the disability scores.Based on strong evidence for short-term efficacy from multiple high-quality trials and moderate evidence for long-term efficacy from at least one high quality trial, we found that fluoroscopic caudal, lumbar interlaminar, and transforaminal epidural injections were efficacious at managing lumbar disc herniation in terms of pain relief and functional improvement.The available evidence suggests that epidural injections performed under fluoroscopy by trained physicians offer improvement in pain and function in well-selected patients with lumbar disc herniation.

Project description:BackgroundLumbar herniated disc (HNP) is mainly treated by conservative management. Epidural steroid injection (ESI) has been an option to treat failed cases prior to surgery. Triamcinolone has been widely used due to its efficacy in bringing about pain reduction for up to three months. However, several reports have shown some severe adverse events. Platelet-rich plasma (PRP) is made from blood through centrifugation. Several studies supported the potential short to long-term effects, and safety of PRP injection in treating HNP. The study objective was to evaluate the efficacy of PRP in treatment of single-level lumbar HNP in comparison to triamcinolone.MethodsThirty patients were treated by transforaminal epidural injections. PRP was obtained from 24 ml venous blood through standardized double-spin protocol. Participants included fifteen patients each being in triamcinolone and PRP groups. The same postoperative protocols and medications were applied. The visual analogue scale of leg (LegVAS), collected at baseline, 2, 6, 12, and 24 weeks, was the primary outcome. The BackVAS, Oswestry Disability Index (ODI), adverse event, and treatment failure were the secondary endpoints.ResultsPlatelet ratio of PRP in fifteen patients was 2.86 ± 0.85. Patients treated by PRP injections showed statistically and clinically significant reduction in LegVAS at 6, 12, and 24 weeks, and in ODI at 24 weeks. It demonstrated comparable results on other aspects. No adverse event occurred in either group.ConclusionNoncommercial epidural double-spin PRP yielded superior results to triamcinolone. Due to its efficacy and safety, the procedure is recommended in treating single level lumbar HNP.Trial registrationNCT, NCT05234840.

Project description:BackgroundDespite transforaminal epidural steroid injection (ESI) being the first choice in patient with recurrent herniated intervertebral disc (HIVD), efficacy of ESI in those patients are not well established. Herein, we evaluate the effectiveness and outcome predictors of fluoroscopic transforaminal ESI for recurrent HIVD.MethodsSeventy-seven patients (48 male; mean age, 51.3 years) with recurrent lumbar HIVD were included and divided into three groups according to initial treatment: conservative treatment, transforaminal ESI, and immediate surgery. ESI effectiveness was evaluated by operation rates, injection numbers in 6 months, and pain reduction (visual analog scale (VAS) scores). Clinical and MRI variables were analyzed as possible outcome predictors. Each subject in the transforaminal ESI group was individually matched to two patients with initial HIVD (control group).ResultsIn the transforaminal ESI group (n = 37), 20 patients (54.1%) did not undergo reoperation. The initial and follow-up VAS scores were significantly higher in the reoperation group (p = 0.014, p = 0.019, respectively). Patients with either paresthesia or motor weakness (12/19, 63.2%) had a significantly higher reoperation rate than patients with only pain (5/18, 27.8%; p = 0.031). Extruded disc ratios ≥2.0 were significantly higher in the reoperation group (10/17, 58.8%; p = 0.048). The reoperation rate in the transforaminal ESI group (17/37, 45.9%) was higher than the operation rate in the control group (6/73, 8.2%; p<0.001).ConclusionTransforaminal ESI was effective in reducing radicular pain in patients with recurrent HIVD. Approximately 54% of patients did not undergo reoperation. An extruded disc ratio ≥2.0 and paresthesia or motor weakness were poor outcome predictors.

Project description:BACKGROUND:Surgery on extraforaminal lumbar disc herniation (ELDH) is a commonly performed procedure. Operating on this type of herniation is known to come with more difficulties than on the frequently seen paramedian lumbar disc herniation (PLDH). However, no comparative data are available on the effectiveness and safety of this operation. We sought out to compare clinical outcomes at 1 year following surgery for ELDH and PLDH. METHODS:Data were collected through the Norwegian Registry for Spine Surgery (NORspine). The primary outcome measure was change at 1 year in the Oswestry Disability Index (ODI). Secondary outcome measures were quality of life measured with EuroQol 5 dimensions (EQ-5D); and numeric rating scales (NRSs). RESULTS:Data of a total of 1750 patients were evaluated in this study, including 72 ELDH patients (4.1%). One year after surgery, there were no differences in any of the patient reported outcome measurements (PROMs) between the two groups. PLDH and ELDH patients experienced similar changes in ODI (-?30.92 vs. -?34.00, P?=?0.325); EQ-5D (0.50 vs. 0.51, P?=?0.859); NRS back (-?3.69 vs. -?3.83, P?=?0.745); and NRS leg (-?4.69 vs. -?4.46, P?=?0.607) after 1 year. The proportion of patients achieving a clinical success (defined as an ODI score of less than 20 points) at 1 year was similar in both groups (61.5% vs. 52.7%, P?=?0.204). CONCLUSIONS:Patients operated for ELDH reported similar improvement after 1 year compared with patients operated for PLDH.

Project description:BackgroundWhile chronic neck pain is a common problem in the adult population, with a typical 12-month prevalence of 30%-50%, there is a lack of consensus regarding its causes and treatment. Despite limited evidence, cervical epidural injections are one of the commonly performed nonsurgical interventions in the management of chronic neck pain.MethodsA randomized, double-blind, active, controlled trial was conducted to evaluate the effectiveness of cervical interlaminar epidural injections of local anesthetic with or without steroids for the management of chronic neck pain with or without upper extremity pain in patients without disc herniation, radiculitis, or facet joint pain.ResultsOne hundred and twenty patients without disc herniation or radiculitis and negative for facet joint pain by means of controlled diagnostic medial branch blocks were randomly assigned to one of two treatment groups, ie, injection of local anesthetic only (group 1) or local anesthetic mixed with nonparticulate betamethasone (group 2). The primary outcome of significant pain relief and improvement in functional status (≥50%) was demonstrated in 72% of group 1 and 68% of group 2. The overall average number of procedures per year was 3.6 in both groups with an average total relief per year of 37-39 weeks in the successful group over a period of 52 weeks.ConclusionCervical interlaminar epidural injections of local anesthetic with or without steroids may be effective in patients with chronic function-limiting discogenic or axial pain.

Project description:BackgroundAdipose and adipose derived regenerative cells (ADRCs) play an increasing role in androgenetic alopecia.ObjectivesThe authors sought to evaluate the safety and feasibility of fat grafts enriched with ADRCs in early androgenetic alopecia.MethodsSeventy-one patients were treated: 16 with Puregraft fat and 1.0 × 106 ADRCs/cm2 scalp; 22 with Puregraft fat and 0.5 × 106 ADRCs/cm2 scalp, 24 with Puregraft fat alone, and 9 with saline control. Treatments were delivered into the skin and subcutaneous layer of the scalp. A total of 40 cm2 of scalp was treated and macrophotography and global photography were obtained at baseline and at 6, 24, and 52 weeks.ResultsA total of 71 patients tolerated the procedures well. No unanticipated associated adverse events were reported. When evaluating all patients at 24 weeks, there were no statistical differences between any of the treatment groups with respect to nonvellus (terminal) hair counts or width. There were increases (mean change from baseline) in terminal hair count for the low-dose ADRC group in the Norwood Hamilton 3 subgroup at week 6 (13.90 ± 16.68), week 12 (11.75 ± 19.42), week 24 (16.56 ± 14.68), and week 52 (2.78 ± 16.15). For this subgroup, the difference in hair count between the low-dose ADRC group and no-fat saline control was statistically significant (P = 0.0318) at week 24.ConclusionsPuregraft fat and ADRCs are safe and well tolerated. In early male hair loss, this therapy demonstrated a statistically significant increase in terminal hair counts relative to the control population at 24 weeks and represents a promising approach for early androgenetic alopecia.Level of evidence: 2
