[PMID: 34184600 DOI: 10.1080/02688697.2021.1923654] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2020] [Revised: 04/21/2021] [Accepted: 04/26/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVE To compare the new zero-profile (Zero-P) fusion cage with regular cage and plate (CP) in the treatment of anterior cervical single-level cervical degenerative diseases. METHODS Patients operated from January 2013 to August 2018 were enrolled. They were divided into the Zero-P group (n = 74 cases) and CP groups (n = 116 cases). Follow-up assessment was at 1, 3, 12, and 24 months after surgery, including the incidence of dysphagia, visual analogue scale (VAS) score, Japanese orthopaedic association (JOA)score, C2-C7 Cobb angle, intervertebral disc height (IDH) and adjacent joint degeneration. RESULTS The operation time and blood loss of patients in Zero-P group were less than those in the CP group, and there was no difference in hospitalization time. All 190 patients were followed up for 24 to 72 months, with an average of 35.29 months. In terms of clinical outcomes, vas and JOA scores of the two groups were significantly improved at one month and the last follow-up. The incidence of dysphagia in the Zero-P group was lower than that in the CP group. On radiological effects, Cobb angle and IDH showed significant correction in both groups, but the degeneration rate of adjacent joints in the Zero-P group was lower than the CP group. CONCLUSIONS In ACDF, the clinical and radiological results of Zero-P and CP devices are satisfactory, but Zero-P cage may be superior in operation time, blood loss, the incidence of dysphagia and adjacent joint degeneration.

Abstract
Objective To gather all systematic reviews of surgical treatment of degenerative cervical diseases and assess their quality, conclusions and outcomes. Methods A literature search for systematic reviews of surgical treatment of degenerative cervical diseases was conducted. Studies should have at least one surgical procedure as an intervention. Included studies were assessed for quality through Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) and Assessment of Multiple Systematic Reviews (AMSTAR) questionnaires. Quality of studies was rated accordingly to their final score as very poor (<30%), poor (30%-50%), fair (50%-70%), good (70%-90%), and excellent (>90%). If an article reported a conclusion addressing its primary objective with supportive statistical evidence for it, they were deemed to have an evidence-based conclusion. Results A total of 65 systematic reviews were included. According to AMSTAR and PRISMA, 1.5% to 6.2% of studies were rated as excellent, while good studies counted for 21.5% to 47.7%. According to AMSTAR, most studies were of fair quality (46.2%), and 6.2% of very poor quality. Mean PRISMA score was 70.2%, meaning studies of good quality. For both tools, performing a meta-analysis significantly increased studies scores and quality. Cervical spondylosis studies reached highest scores among diseases analyzed. Authors stated conclusions for interventions compared in 70.7% of studies, and only two of them were not supported by statistical evidence. Conclusion Systematic reviews of surgical treatment of cervical degenerative diseases present “fair” to “good” quality in their majority, and most of the reported conclusions are supported by statistical evidence. Including a meta-analysis significantly increases the quality of a systematic review.

Abstract
BACKGROUND The effectiveness of surgical interventions for cervical degenerative disorders has been investigated in multiple systematic reviews. Differences in study population (e.g., patients with myelopathy and/or radiculopathy) were often neglected. Therefore, the objective of this study was to investigate the effectiveness of surgical interventions for patients with symptoms of cervical radiculopathy without myelopathy by conducting a systematic review and meta-analysis based on randomized controlled trials (RCTs). METHODS A comprehensive systematic search was conducted in MEDLINE, Embase, and CENTRAL (Cochrane Central Register of Controlled Trials) to identify RCTs that investigated the effectiveness of surgical interventions using an anterior or posterior approach compared with other interventions for patients with pure cervical radiculopathy. Outcomes were success rates (Odom criteria, similar rating scales, or percentage of patients who improved), complication and reoperation rates, work status, disability (Neck Disability Index), and pain (arm and neck). The Cochrane risk-of-bias tool was used to assess the likelihood of the risk of bias. A random-effects model was used. Heterogeneity among study results (I2 ≥ 50% or p < 0.05) was explored by conducting subgroup analyses. Funnel plots were used to assess the likelihood of publication bias. RESULTS A total of 21 RCTs were included, comprising 1,567 patients. For all outcomes, among all surgical techniques, only 1 pooled estimate showed a significant effect on success rate, which was in favor of anterior cervical discectomy with fusion compared with anterior cervical discectomy without an intervertebral spacer (p = 0.02; risk ratio [RR] = 0.87; 95% confidence interval [CI] = 0.77 to 0.98). Complication rates were higher when autologous bone graft from the iliac crest was used as an intervertebral spacer (p < 0.01; RR = 3.40; 95% CI = 1.56 to 7.43), related to donor-site morbidity. CONCLUSIONS This meta-analysis demonstrated consistent results regarding clinical outcome for pure cervical radiculopathy among all studied interventions. Complication and reoperation rates were also similar, with the exception of higher complication rates in patients in whom autologous bone grafts were used. On the basis of clinical outcome and safety, there is no superior surgical intervention for pure cervical radiculopathy. LEVEL OF EVIDENCE Therapeutic Level I.

Abstract
Objectives Cervical disc arthroplasty (CDA) has become an alternative treatment for cervical radiculopathy and myelopathy. This technique preserves appropriate motion at both the index and adjacent disc levels and consequently may prevent adjacent segment degeneration (ASD). The authors performed a meta-analysis to compare the safety and efficacy of CDA to those of the gold standard, anterior cervical discectomy and fusion (ACDF). Both surgical and clinical parameters were employed to verify the hypothesis that CDA can reduce the risk of ASD. Methods The meta-analysis comprised high-quality randomized controlled trials that compared CDA and ACDF treatments of cervical degenerative disc disease. Included papers reported data for at least one of the following outcomes: 1) surgical parameters, 2) questionnaire clinical indices (pre- and postoperative values), and 3) complication rates at 24 months; in addition, for ASD we analyzed 60 month or longer follow-ups. We used mean differences (MDs) or ORs to compare treatment effects between CDA and ACDF. Results Twenty studies with 3,656 patients (2,140 with CDA and 1,516 with ACDF) met the inclusion criteria. CDA surgery, with mean duration longer than that of ACDF, was associated with higher blood loss. Visual analog scale neck pain score was significantly smaller for CDA (mean difference =−2.30, 95% CI [−3.72; −0.87], P=0.002). The frequency of dysphagia/dysphonia (OR =0.69, 95% CI [0.49; 0.98], P=0.04) as well as the long-term ASD rate for CDA was significantly smaller (OR =0.33, 95% CI [0.21; 0.50], P<0.0001). Conclusion A significantly lower probability of ASD reoperations in the CDA cohort after a 60-month or longer follow-up was the most important finding of this study. Despite the moderate quality of this evidence, the pooled data corroborated for the very first time that CDA was efficacious in preventing ASD.

Long-Term Outcomes After Microscopic Anterior Cervical Foraminotomy with a Minimum 10-Year Follow-Up. World Neurosurg 2018; 122:e67-e80. [PMID: 30240855 DOI: 10.1016/j.wneu.2018.09.049] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2018] [Revised: 09/05/2018] [Accepted: 09/07/2018] [Indexed: 11/21/2022]
Abstract
BACKGROUND Microscopic anterior cervical foraminotomy (MACF) is a surgical technique for unilateral cervical radiculopathy that preserves segmental motion and avoids adjacent segmental degeneration, but little is known of its long-term outcomes. METHODS A retrospective minimum 10-year follow-up study was conducted on patients treated by 1 surgeon. Clinical outcomes were assessed using a visual analog scale of neck and arm pain, Neck Disability Index, and Odom criteria. Surgical outcomes were assessed using additional procedure rates. Radiologic outcomes were estimated by measuring disc heights, segmental angles, and range of motion at the surgical level and adjacent segments, and so on. RESULTS Of the 94 patients who underwent MACF between January 2000 and December 2004 by 1 surgeon, 69 were enrolled in this study. Median follow-up period was 11.9 years (range, 10.0-14.5 years). Visual analog scales for neck or arm pain and Neck Disability Index improved significantly during follow-up period (P < 0.001). Also, according to the Odom criteria, an excellent or good outcome was achieved in 62 patients (89.9%) at final follow-up. An additional procedure was performed in 10 patients (14.5%) for symptom recurrence during the follow-up period. The only risk factor found to be related to the need for an additional procedure was a small preoperative range of motion at the surgical level (P = 0.018). Although mean disc height at the surgical level decreased significantly (from 6.23 ± 1.10 to 5.17 ± 1.12 mm; P = 0.004), adjacent discs were not significantly affected. CONCLUSIONS Although some radiologic results have shortcomings, the results of this study suggest that MACF has favorable long-term outcomes.

Abstract
Background ACDF has been considered as the gold standard in the treatment of single level cervical disk protrusion. However, it may cause adjacent level degeneration due to regional biomechanical changes. TDR has been applied with satisfactory results for over a decade, but there is no consensus if TDR is safer and more efficient than ACDF. The current study was carried out to compare the efficiency and safety of TDR and ACDF in the treatment of patients with single level cervical disk protrusion. Methods One hundred forty-five consecutive patients who underwent either TDR or ACDF in our center were included in the current study. Time of surgery, intraoperative blood loss, VAS arm and neck pain scores, ROM, ODI, SF36 and Patient satisfaction were compared before the surgery, after the surgery, and during follow up 1, 3, 5, 8 years after the surgery. Results The time of surgery was 64.6 ± 20.7 min in the ACDF group and 69.4 ± 19.3 min in the TDR group; intraoperative hemorrhage was 67.2 ± 14.3 ml in ACDF group and 70.7 ± 18.6 ml in TDR group. There were no significant differences between two groups concerning time of surgery and intraoperative blood loss. No differences were found concerning patient satisfaction between the two groups during the follow up (P > 0.05). Significant differences were found between the groups concerning VAS arm and neck pain scores, ROM, ODI and SF36 after the surgery and during the 8 year follow up. Conclusion TDR may be a more effective approach than ACDF for treating patients with single level cervical disk protrusion. Keywords Cervical disk herniation, ACDF, TDR, Retrospective study

Abstract
BACKGROUND CONTEXT The results of meta-analyses are frequently reported, but understanding and interpreting them is difficult for both clinicians and patients. Statistical significances are presented without referring to values that imply clinical relevance. PURPOSE This study aimed to use the minimal clinically important difference (MCID) to rate the clinical relevance of a meta-analysis. STUDY DESIGN This study is a review of the literature. PATIENT SAMPLE This study is a review of meta-analyses relating to a specific topic, clinical results of cervical arthroplasty. OUTCOME MEASURE The outcome measure used in the study was the MCID. METHODS We performed an extensive literature search of a series of meta-analyses evaluating a similar subject as an example. We searched in Pubmed and Embase through August 9, 2016, and found articles concerning meta-analyses of the clinical outcome of cervical arthroplasty compared with that of anterior cervical discectomy with fusion in cases of cervical degenerative disease. We evaluated the analyses for statistical significance and their relation to MCID. MCID was defined based on results in similar patient groups and a similar disease entity reported in the literature. RESULTS We identified 21 meta-analyses, only one of which referred to MCID. However, the researchers used an inappropriate measurement scale and, therefore, an incorrect MCID. The majority of the conclusions were based on statistical results without mentioning clinical relevance. CONCLUSIONS The majority of the articles we reviewed drew conclusions based on statistical differences instead of clinical relevance. We recommend introducing the concept of MCID while reporting the results of a meta-analysis, as well as mentioning the explicit scale of the analyzed measurement.

Abstract
Objective: To investigate the effectiveness of combined laser needle-knife and massage on cervical spondylotic vertebral arteriopathy patients. Summary of background data: With the recent rise of electronic businesses, the incidence of cervical spondylosis has also risen rapidly. Methods: Cervical spondylotic vertebral arteriopathy patients were treated using laser needle-knife with massage, and compared to patients who only received the massage. A 3D anatomical and hemodynamic model was developed. Results: The symptomatic and functional overall scores were reduced by 71.43% after the combined treatment. Results from the finite element analysis indicated that the maximum flow rate of the left vertebral artery was improved by 47.52% and the right was improved by 38.67%. Conclusion: A combined treatment of cervical spondylotic vertebral arteriopathy using laser needle-knife and massage is an effective approach with a therapeutic mechanism closely related to hemodynamics.

Cervical disc arthroplasty (CDA) versus anterior cervical discectomy and fusion (ACDF) in symptomatic cervical degenerative disc diseases (CDDDs): an updated meta-analysis of prospective randomized controlled trials (RCTs). SPRINGERPLUS 2016; 5:1188.

Abstract
PURPOSE This meta-analysis of randomized controlled trials (RCTs) aims to evaluate the efficacy and safety in cervical disc arthroplasty (CDA) and anterior cervical discectomy and fusion (ACDF) for treating cervical degenerative disc diseases (CDDDs). METHODS The authors searched RCTs in the electronic databases (Cochrane Central Register of Controlled Trials, PubMed, EMBASE, Medline, Embase, Springer Link, Web of Knowledge, OVID and Google Scholar) from their establishment to march 2016 without language restrictions. We also manually searched the reference lists of articles and reviews for possible relevant studies. Researches on CDA versus ACDF in CDDDs were selected in this meta-analysis. The quality of all studies was assessed and effective data was pooled for this meta-analysis. Outcome measurements were surgical parameters (operative time, blood loss, and length of hospital stay), clinical indexes [neck disability index (NDI), neurological success, range of motion (ROM), Visual Analogue Score (VAS)], complications [the number of adverse events, adjacent segment disease (ASD), and reoperation]. Subgroup analysis, sensitivity analysis, and publication bias assessment were also performed, respectively. The meta-analysis was performed with software revman 5.3. RESULTS 37 articles (20 RCTs) with a total 4004 patients (2212 in the CDA and 1792 in the ACDF) met inclusion criteria. Eight types of disc prostheses were used in the included studies. Patients were followed up for at least 2 years in all the studies. No statistically significant differences were found between CDA and ACDF for blood loss [SMD -0.02; 95 % CI (-0.20, 0.17)], length of hospital stay [MD -0.06; 95 % CI (-0.19, 0.06)]. Statistical differences were found between operative time [MD 14.22; 95 % CI (6.73, 21.71)], NDI [SMD -0.27; 95 % CI (-0.43, -0.10)], neurological success [RR 1.13; 95 % CI (1.08, 1.18)], ROM [MD 6.72; 95 % CI (5.72, 7.71)], VAS of neck [SMD -0.40; 95 % CI (-0.75, -0.04)], VAS of arm [SMD -0.55; 95 % CI (-1.04, -0.06)], the rate of adverse events [RR 0.72 95 % CI (0.53, 0.96)], the rate of ASD [RR 0.62; 95 % CI (0.43, 0.88)], and reoperation [RR 0.50; 95 % CI (0.39, 0.63)]. Subgroup analysis stratified by different types of disc prostheses was also performed. CONCLUSIONS CDA is associated with higher clinical indexes and fewer complications than ACDF, indicating that it is a safe and effective treatment for CDDDs. However, the operative time of CDA is longer than ACDF. Because of some limitations, these findings should be interpreted with caution. Additional studies are needed. Large, definitive RCTs are needed.

[PMID: 27465393 DOI: 10.1007/s10143-016-0765-0] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2016] [Revised: 05/30/2016] [Accepted: 06/23/2016] [Indexed: 01/11/2023]
Abstract
The present article reviews the design rationale of currently available cervical disc replacements. Recent prospective randomized control trials comparing cervical disc replacement and anterior fusion have demonstrated safety as well as equal or superior clinical results. Increasingly, more devices are becoming available on the market. Understanding design rationale will provide context for the surgeon to optimize decision making for the most appropriate prosthesis. Cervical arthroplasty is a technique that is undergoing rapid design refinement and development. Further improvements in device design will enable patient-specific device selection. Understanding the design rationale and complication profile of each device will improve clinical and radiographic outcomes.
