Ontology highlight
ABSTRACT: Background
Cervical radiculopathy is characterized by dysfunction of the nerve root usually caused by a cervical disk herniation. The most important symptom is pain, radiating from the neck to the arm. When conservative treatment fails, surgical treatment is indicated to relieve symptoms. During the last decades, multiple fusion techniques have been developed, although without clinical evidence for added value of fusion over non-fusion.Methods
The surgical procedure of anterior cervical discectomy without fusion is performed step by step, leading to removal of the entire intervertebral disk.Conclusion
Anterior cervical discectomy without fusion is a safe and effective treatment for cervical disk herniation.

Project description:ObjectiveGiant cervical disc herniation (GCDH) was defined as a herniated intervertebral disc that accounted for more than 50% of the spinal canal. The purpose of this study was to analyse the feasibility of anterior cervical discectomy and fusion (ACDF) for the treatment of GCDH.MethodsPatient demographic and imaging data, clinical results, and perioperative complications were analysed retrospectively.ResultsA total of 23 patients were included in the study. Spinal cord recovery pulsation was observed under a microscope in all cases. Postoperative magnetic resonance imaging showed complete decompression of the spinal cord and no residual intervertebral disc. The patients were followed up for 12 to 18 months. The average visual analogue scale score and Neck Disability Index decreased from 8.6 ± 0.5 and 86.0 ± 2.7% to 2.2 ± 0.2 and 26.7 ± 2.0%, respectively, three days after surgery. The average Japanese Orthopedic Association score increased from 6.9 ± 2.1 to 13.9 ± 1.1. The cervical spinal cord function improvement rate was 69.3%. No neurological complications after surgery were observed.ConclusionThis study shows that ACDF is feasible for the treatment of GCDH disease. The results indicate that this approach can be used to safely remove herniated disc fragments, effectively relieve compression of the spinal cord, and improve neurological function.

Project description:ObjectiveSymptomatic cervical disc disease (SCDD) is a common degenerative disease, and Discover artificial cervical disc, a new-generation nonconstrained artificial disk, has been developed and performed gradually to treat it. We performed this meta-analysis to compare the efficacy and safety between Discover cervical disc arthroplasty (DCDA) and anterior cervical discectomy and fusion (ACDF) for SCDD.MethodsAn exhaustive literature search of PubMed, EMBASE, and the Cochrane Library was conducted to identify randomized controlled trials that compared DCDA with ACDF for patients suffering SCDD. A random-effect model was used. Results were reported as standardized mean difference or risk ratio with 95% confidence interval.ResultsOf 33 articles identified, six studies were included. Compared with ACDF, DCDA demonstrated shorter operation time (P < 0.0001), and better range of motion (ROM) at the operative level (P < 0.00001). But no significant differences were observed in blood loss, neck disability index (NDI) scores, neck and arm pain scores, Japanese orthopaedic association (JOA) scores, secondary surgery procedures and adverse events (P > 0.05). Subgroup analyses did not demonstrated significant differences.ConclusionIn conclusion, DCDA presented shorter operation time, and better ROM at the operative level. However, no significant differences were observed in blood loss, NDI scores, neck and arm pain scores, JOA scores, secondary surgery procedures and adverse events between the two groups. Additionally, more studies of high quality with mid- to long-term follow-up are required in future.

Project description:Study Design Retrospective review. Objective The objective of this study is to describe the natural history of neurologic recovery after anterior cervical discectomy and fusion (ACDF). Methods Patients between 18 and 80 years of age, diagnosed with cervical radiculopathy, who underwent single-level ACDF and were followed for a minimum of 2 years were identified from a single-center database. Sensory and motor deficits were documented and graded based on physical examination findings at preoperative and postoperative visits, and used to calculate deficit rates. Results One hundred eighteen patients were included in the study. Mean age was 46 ± 9.2 years and mean follow-up time was 3.8 ± 2.1 years. At the time of surgery, 66% had a sensory deficit. Recovery of sensory function was seen in 85% of patients within 1 year. At final follow-up, new sensory deficits had developed in 30% of patients, 60% of whom had adjacent-level sensory deficits. Patients with preoperative sensory deficits tended to be more likely to develop a new deficit postoperatively (p = 0.05). At the time of surgery, 55% had a motor deficit. Recovery of motor function was seen in 95% of patients within 1 year, and 14% developed new postoperative motor deficits by final follow-up. Of those patients who developed a new motor deficit postoperatively, 76% did so at an adjacent level. Conclusions In our series, a high percentage of patients recovered neurologic function during the first year after ACDF. Adjacent-level and remote-level degeneration were large contributors to neurologic deficits that occurred in subsequent years.

Project description:Highlights • Cervical stenosis represents a progressive pathology with great variation in trajectory.• Anterior cervical discectomy and fusion (ACDF) may modify the course of one's disease.• There are significant disparities in accessibility and outcomes of ACDF.• Research and policymaking should be prioritized on more equitable application of ACDF. Background Disparities in neurosurgical care have emerged as an area of interest when considering the impact of social determinants on access to health care. Decompression via anterior cervical discectomy and fusion (ACDF) for cervical stenosis (CS) may prevent progression towards debilitating complications that may severely compromise one's quality of life. This retrospective database analysis aims to elucidate demographic and socioeconomic trends in ACDF provision and outcomes of CS-related pathologies. Methods The Healthcare Cost and Utilization Project National Inpatient Sample database was queried between 2016 and 2019 using International Classification of Diseases 10th edition codes for patients undergoing ACDF as a treatment for spinal cord and nerve root compression. Baseline demographics and inpatient stay measures were analyzed. Results Patients of White race were significantly less likely to present with manifestations of CS such as myelopathy, plegia, and bowel-bladder dysfunction. Meanwhile, Black patients and Hispanic patients were significantly more likely to experience these impairments representative of the more severe stages of the degenerative spine disease process. White race conferred a lesser risk of complications such as tracheostomy, pneumonia, and acute kidney injury in comparison to non-white race. Insurance by Medicaid and Medicare conferred significant risks in terms of more advanced disease prior to intervention and negative inpatient. Patients in the highest quartile of median income consistently fared better than patients in the lowest quartile across almost every aspect ranging from degree of progression at initial presentation to incidence of complications to healthcare resource utilization. All outcomes for patients age > 65 were worse than patients who were younger at the time of the intervention. Conclusions Significant disparities exist in the trajectory of CS and the risks associated with ACDF amongst various demographic cohorts. The differences between patient populations may be reflective of a larger additive burden for certain populations, especially when considering patients’ intersectionality.

Project description:BackgroundAnterior cervical discectomy and fusion is a standard treatment for symptomatic cervical disc disease, but pseudarthrosis and accelerated adjacent-level disc degeneration may develop. Cervical disc arthroplasty was developed to preserve the kinematics of the functional spinal unit. Trials comparing arthroplasty with anterior cervical discectomy and fusion have shown unclear benefits in terms of clinical results, neck motion at the operated level, adverse events, and the need for secondary surgical procedures.MethodsOnly randomized clinical trials were included in this meta-analysis, and the search strategy followed the requirements of the Cochrane Library Handbook. Two reviewers independently assessed the methodological quality of each included study and extracted the relevant data.ResultsTwenty-seven randomized clinical trials were included; twelve studies were Level I and fifteen were Level II. The results of the meta-analysis indicated longer operative times, more blood loss, lower neck and arm pain scores reported on a visual analog scale, better neurological success, greater motion at the operated level, fewer secondary surgical procedures, and fewer such procedures that involved supplemental fixation or revision in the arthroplasty group compared with the anterior cervical discectomy and fusion group. These differences were significant (p < 0.05). The two groups had similar lengths of hospital stay, Neck Disability Index scores, and rates of adverse events, removals, and reoperations (p > 0.05).ConclusionsThe meta-analysis revealed that anterior cervical discectomy and fusion was associated with shorter operative times and less blood loss compared with arthroplasty. Other outcomes after arthroplasty (length of hospital stay, clinical indices, range of motion at the operated level, adverse events, and secondary surgical procedures) were superior or equivalent to the outcomes after anterior cervical discectomy and fusion.

Project description:Study designSecondary analysis of data from a concurrent randomized trial and cohort study.ObjectiveThe aim of this study was to determine risks and predictors of recurrent pain following standard open discectomy for subacute/chronic symptomatic lumbar disc herniation (SLDH).Summary of background dataMost previous studies of recurrence after discectomy do not explicitly define pain resolution and recurrence, and do not account for variable durations of time at risk for recurrence.MethodsWe used survival analysis methods to examine predictors of leg pain recurrence. For individuals with initial resolution of leg pain, we defined recurrent leg pain as having leg pain, receiving lumbar epidural steroid injections, or undergoing lumbar surgery subsequent to initial leg pain resolution. We calculated cumulative risks of leg pain recurrence using Kaplan-Meier survival curves, and examined predictors of recurrence using Cox proportional hazards models. We used similar methods to examine LBP recurrence.ResultsOne- and three-year cumulative risks of leg pain recurrence were 20% and 45%, respectively. One- and three- year leg pain recurrence risks were substantially lower in participants with complete initial resolution of leg pain (17% and 41%, respectively) than in those without (27% and 54%, respectively). In multivariate analyses, complete leg pain resolution (adjusted hazard ratio [aHR] 0.69; 95% confidence interval [CI] 0.52-0.90), smoking (aHR 1.68 [95% CI 1.22-2.33]), and depression (aHR 1.74 [95% CI 1.18-2.56]) predicted leg pain recurrence. The 1- and 3-year risk of LBP recurrence was 29% and 65%, respectively. LBP recurrence risk at 3 years was substantially lower in participants with complete initial resolution of LBP than in those without, but not at 1 year.ConclusionRecurrence of leg pain and LBP is common after discectomy for SLDH. Cumulative risks of both leg pain and LBP recurrence were generally lower in participants achieving complete initial resolution of pain post-discectomy.Level of evidence2.

Project description:BackgroundAnterior cervical discectomy and fusion is a standard surgical treatment for cervical radiculopathy and myelopathy, but reoperations sometimes are performed to treat complications of fusion such as pseudarthrosis and adjacent-segment degeneration. A cervical disc arthroplasty is designed to preserve motion and avoid the shortcomings of fusion. Available evidence suggests that a cervical disc arthroplasty can provide pain relief and functional improvements similar or superior to an anterior cervical discectomy and fusion. However, there is controversy regarding whether a cervical disc arthroplasty can reduce the frequency of reoperations.Questions/purposesWe performed a meta-analysis of randomized controlled trials (RCTs) to compare cervical disc arthroplasty with anterior cervical discectomy and fusion regarding (1) the overall frequency of reoperation at the index and adjacent levels; (2) the frequency of reoperation at the index level; and (3) the frequency of reoperation at the adjacent levels.MethodsPubMed, EMBASE, and the Cochrane Register of Controlled Trials databases were searched to identify RCTs comparing cervical disc arthroplasty with anterior cervical discectomy and fusion and reporting the frequency of reoperation. We also manually searched the reference lists of articles and reviews for possible relevant studies. Twelve RCTs with a total of 3234 randomized patients were included. Eight types of disc prostheses were used in the included studies. In the anterior cervical discectomy and fusion group, autograft was used in one study and allograft in 11 studies. Nine of 12 studies were industry sponsored. Pooled risk ratio (RR) and associated 95% CI were calculated for the frequency of reoperation using random-effects or fixed-effects models depending on the heterogeneity of the included studies. A funnel plot suggested the possible presence of publication bias in the available pool of studies; that is, the shape of the plot suggests that smaller negative or no-difference studies may have been performed but have not been published, and so were not identified and included in this meta-analysis.ResultsThe overall frequency of reoperation at the index and adjacent levels was lower in the cervical disc arthroplasty group (6%; 108/1762) than in the anterior cervical discectomy and fusion group (12%; 171/1472) (RR, 0.54; 95% CI, 0.36-0.80; p = 0.002). Subgroup analyses were performed according to secondary surgical level. Compared with anterior cervical discectomy and fusion, cervical disc arthroplasty was associated with fewer reoperations at the index level (RR, 0.50; 95% CI, 0.37-0.68; p < 0.001) and adjacent levels (RR, 0.52; 95% CI, 0.37-0.74; p < 0.001).ConclusionsCervical disc arthroplasty is associated with fewer reoperations than anterior cervical discectomy and fusion, indicating that it is a safe and effective alternative to fusion for cervical radiculopathy and myelopathy. However, because of some limitations, these findings should be interpreted with caution. Additional studies are needed.Level of evidenceLevel I, therapeutic study.

Project description:BackgroundPercutaneous transforaminal endoscopic discectomy (PTED) has emerged as a less invasive technique to treat symptomatic lumbar disk herniation (LDH). PTED is performed under local anesthesia with the advantage of immediate intraoperative feedback of the patient. In this paper, the technique is described as conducted in our hospital.MethodsPTED is performed under local anesthesia in prone position on thoracopelvic supports. The procedure is explained stepwise: e.g. marking, incision, introduction of the 18-gauge needle and guidewire to the superior articular process, introduction of the TomShidi needle and foraminotomy up to 9 mm, with subsequently removal of disk material through the endoscope. Scar size is around 8 mm.ConclusionPTED seems a promising alternative to conventional discectomy in patients with LDH and can be performed safely.

Project description:ObjectiveCervical sagittal alignment changes (CSACs) influence outcomes and health-related quality-of-life. Anterior cervical discectomy and fusion (ACDF), laminectomy with fusion (LCF), and laminoplasty (LP) are common treatments for multisegmental cervical spondylotic myelopathy; however, these approaches need to be compared.MethodsOur study included 167 patients who underwent ACDF, LCF, or LP. Patients were divided into four groups according to C2-C7 Cobb angle (CL): kyphosis (CL < 0°), straight (0° ≤ CL < 10°), lordosis (10° ≤ CL < 20°), and extreme lordosis (20° ≤ CL) groups. CSACs consist of two parts. CSAC from the preoperative period to the postoperative period is surgical correction change (SCC). CSAC from the postoperative period to the final follow-up period is postoperative lordosis preserving (PLP). Outcomes were evaluated using the Japanese Orthopaedic Association score and the neck disability index.ResultsACDF, LCF, and LP had equivalent outcomes. ACDF had greater SCC than LCF and LP. During follow-up, lordosis decreased in the ACDF and LCF groups but increased in the LP group. For straight alignment, ACDF had greater CSAC and greater SCC than the LCF and LP groups but similar PLP. For lordosis alignment, ACDF and LP had positive PLP, and LCF had negative PLP. For extreme lordosis, ACDF, LP, and LCF had negative PLP; however, cervical lordosis in the LP group was relatively stable during follow-up.ConclusionsACDF, LCF, and LP have different CSAC, SCC, and PLP according to a four-type cervical sagittal alignment classification. Preoperative cervical alignment is an important consideration in deciding the type of surgical treatment in CSM.

Project description:Retrospective cohort study.To identify factors that are independently associated with increased surgical drain output in patients who have undergone ACDF.Surgical drains are typically placed after ACDF to reduce the risk of complications associated with neck hematoma. The orthopedic literature has repeatedly challenged the use of surgical drains after many procedures, and there are currently no guidelines for determining which patients are most likely to benefit from drain placement after ACDF.Consecutive patients who underwent elective ACDF with surgical drain placement at a single academic institution between January 2011 and February 2013 were identified using billing records. Patient information was abstracted from the medical record. Patients were categorized on the basis of normal or increased total drain output, with increased drain output defined as total drain output 50th percentile (30 mL) or more. A multivariate logistic regression was used to determine which factors were independently associated with increased drain output.A total of 151 patients with ACDF met inclusion criteria. Total drain output was in the range from 0 mL to 265 mL. The average drain output for this cohort was 42.3 ± 45.5 mL (mean ± standard deviation). Among all patients in the study, 80 patients had increased drain output (drain output ?50th percentile or 30 mL).Multivariate analysis identified 3 independent predictors of increased drain output: age 50 years or more (odds ratio [OR] = 3.9), number of levels (2 levels, OR = 2.7; 3-4 levels, OR = 17.0), and history of smoking (OR = 2.8). One patient developed a postoperative neck hematoma while a drain was in place.Patients with the factors associated with increased drain output identified in the earlier text may benefit most from surgical drain placement after ACDF. Nonetheless, neck hematoma is still possible even with drain use.3.
