Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE The purposes of this study were to determine the rate of improvement of significant preoperative weakness, identify risk factors for failure to improve, and characterize the motor recovery of individual motor groups. SUMMARY OF BACKGROUND DATA While neck and arm pain reliably improve following anterior cervical discectomy and fusion (ACDF), the frequency and magnitude of motor recovery following ACDF remain unclear. METHODS We performed a retrospective review of patients undergoing 1-4-level ACDF at a single institution between September 2015 and June 2016. Patients were subdivided into 2 groups based upon the presence or absence of significant preoperative weakness, which was defined as a motor grade <4 in any single upper extremity muscle group. Clinical notes were reviewed to determine affected muscle groups, rates of motor recovery, and risk factors for failure to improve. RESULTS We identified 618 patients for inclusion. Significant preoperative upper extremity weakness was present in 27 patients (4.4%). Postoperatively, 19 of the affected patients (70.3%) experienced complete strength recovery, and 5 patients (18.5%) experienced an improvement in muscle strength to a motor grade ≥4. The rate of motor recovery postoperatively was 85.7% in the triceps, 83.3% in the finger flexors, 83.3% in the hand intrinsics, 50.0% in the biceps, and 25.0% in the deltoids. Risk factors for failure to experience significant motor improvement were the presence of myelomalacia (odds ratio: 28.9, P <0.01) and the performance of >2 levels of ACDF (odds ratio: 10.1, P <0.01). CONCLUSIONS Patients with substantial preoperative upper extremity weakness can expect high rates of motor recovery following ACDF, though patients with deltoid weakness, myelomalacia, and >2 levels of ACDF are less likely to experience significant motor improvement.

Abstract
BACKGROUND: One of the most common causes of spinal cord dysfunction is cervical spondylotic myelopathy (CSM) especially in the elderly. Prognostic indices can aid the surgeon preoperatively to detect the patients’ prognosis.
AIM: The aim of the work is to better assess patients and to find possible indicators for post-operative improvement or deterioration in CSM patients.
METHODS: Forty patients with multiple levels CSM, admitted and operated on in the Neurosurgery Department of Cairo University Hospitals, have been enrolled randomly in this study after fulfilling the criteria for CSM surgical intervention. The patient age, complaint duration, number of levels affected, signal intensity on T1-weighted and T2-weighted magnetic resonance (MR) images, Japan Orthopedic Association (JOA) scoring system, and Nurick’s score were evaluated before surgery and correlated with outcome after 1 year follow-up.
RESULTS: About 80% of patients improved after operation with average pre- and post-operative JOA and Nurick scores about 11.23 and 3.12; 14.1 and 1.6, respectively. Patient age, sex, number of levels affected, and signal intensity on T1- weighted and T2-weighted MR images were not significantly associated with post-operative improvement, p > 0.05. However, the only significant prognostic factor was the duration of symptoms if less than 1 year with p < 0.05.
CONCLUSION: Short complaint duration coupled with close intra-operative monitoring was directly correlated with good CMS operation outcome while age, sex, number of levels affected, presence of cord signal on MR imaging, and surgical approach appear to have no significant effect on outcome.

Abstract
INTRODUCTION Anterior cervical corpectomy and fusion (ACCF) for cervical ossification of the posterior longitudinal ligament (OPLL) is associated with a high incidence of surgery-related complications. A novel anterior decompression technique (vertebral body sliding osteotomy [VBSO]) has been developed to prevent such complications. This study attests the efficacy and safety of VBSO versus those of standard ACCF. METHODS Patients requiring surgery for cervical OPLL underwent VBSO (24 patients) or ACCF (38 patients). Operating time, estimated blood loss, neurologic outcomes, complications, and various radiographic parameters were investigated. RESULTS The VBSO group showed a shorter mean operating time and less estimated blood loss versus the ACCF group. Sixteen patients in the ACCF group experienced various complications, namely neurologic deficit (two patients), cerebrospinal fluid leakage (four patients), graft migration (three patients), and pseudarthrosis (seven patients). In the VBSO group, only pseudarthrosis was reported (two patients). CONCLUSIONS VBSO provides similar neurologic outcomes with a shorter operating time and less bleeding compared with ACCF. Surgeons do not need to directly manipulate the OPLL mass or dissect the interspace between the OPLL and dura mater. Therefore, this technique may decrease the incidence of surgery-related complications. STUDY DESIGN Retrospective comparative study.

Finnish Trial on Practices of Anterior Cervical Decompression and Fusion (FACADE): a protocol for a prospective randomised non-inferiority trial comparing outpatient versus inpatient care. BMJ Open 2019; 9:e032575. [PMID: 31772100 PMCID: PMC6886918 DOI: 10.1136/bmjopen-2019-032575] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2019] [Revised: 09/22/2019] [Accepted: 10/29/2019] [Indexed: 11/28/2022] Open
Abstract
INTRODUCTION Although a great majority of patients with cervical radiculopathy syndrome can successfully be treated non-operatively, a considerable proportion experience persistent symptoms, severe enough to require neurosurgical intervention. During the past decade, cervical spine procedures have increasingly been performed on an outpatient basis and retrospective database analyses have shown this to be feasible and safe. However, there are no randomised controlled studies comparing outpatient care with inpatient care, particularly with emphasis on the patients' perception of symptom relief and their ability to return to normal daily activities and work. METHODS AND ANALYSIS This is a prospective, randomised, controlled, parallel group non-inferiority trial comparing the traditional hospital surveillance (inpatient, patients staying in the hospital for 1-3 nights after surgery) with outpatient care (discharge on the day of the surgery, usually within 6-8 hours after procedure) in patients who have undergone anterior cervical decompression and fusion procedure. To determine whether early discharge (outpatient care) is non-inferior to inpatient care, we will randomise 104 patients to these two groups and follow them for 6 months using the Neck Disability Index (NDI) as the primary outcome. We expect that early discharge is not significantly worse than the current care in terms of change in NDI. Non-inferiority will be declared if the mean improvement for outpatient care is no worse than the mean improvement for inpatient care, by a margin of 17.3%. We hypothesise that a shorter hospital stay results in more rapid return to normal daily activities, shorter duration of sick leave and decreased secondary costs to healthcare system. Secondary outcomes in our study are arm pain and neck pain using the Numeric Rating Scale, operative success (Odom's criteria), patient's satisfaction to treatment, general quality of life (EQ-5D-5L), Work Ability Score, sickness absence days, return to previous leisure activities and complications. ETHICS AND DISSEMINATION The study was approved by the institutional review board of the Helsinki and Uusimaa Hospital District on 6 June 2019 (1540/2019) and duly registered at ClinicalTrials.gov. We will disseminate the findings of this study through peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER NCT03979443.

Abstract
BACKGROUND The Odom criteria, established in 1958, are a widely used, 4-point rating scale for assessing the clinical outcome after cervical spine surgery. Surprisingly, the Odom criteria have never been validated, to our knowledge. The aim of this study was to investigate the reliability and validity of the Odom criteria for the evaluation of surgical procedures of the cervical spine. METHODS Patients with degenerative cervical spine disease were included in the study and divided into 2 subgroups on the basis of their most predominant symptom: myelopathy or radiculopathy. Reliability was assessed with interrater and test-retest design using quadratic weighted kappa coefficients. Construct validity was assessed by means of hypotheses testing. To evaluate whether the Odom criteria could act as a global perceived effect (GPE) scale, we assessed concurrent validity by comparing area under the curve (AUC) values of receiver operating characteristic (ROC) curves for the set of questionnaires. RESULTS A total of 110 patients were included in the study; 19 were excluded, leaving 91 in our analysis. Reliability assessments showed κ = 0.77 for overall interrater reliability and κ = 0.93 for overall test-retest reliability. Interrater reliability was κ = 0.81 for the radiculopathy subgroup and κ = 0.68 for the myelopathy subgroup. At least 75% of the hypotheses were met. The AUCs showed similar characteristics between the Odom criteria and GPE scale. CONCLUSIONS The Odom criteria met the predefined criteria for reliability and validity. Therefore, the Odom criteria may be used to assess surgical outcome after a cervical spine procedure, specifically for patients presenting with radicular symptoms. The results of previous studies that have been deemed less trustworthy because of the use of the Odom criteria should be reconsidered.

Abstract
Aim: The objective of this study was to systematically compare the safety and efficacy of porous tantalum metal (TM) implants and autograft in single-level anterior cervical discectomy and fusion. Methods: Potential academic articles were acquired from the Cochrane Library, Medline, PubMed, Embase, Science Direct and other databases. The time range used was from the inception of the electronic databases to March 2018. Gray studies were identified from the references of included literature reports. STATA version 11.0 (Stata Corporation, TX, USA) was used to analyze the pooled data. Results: Four randomized, controlled trials (RCTs) were identified according to the retrieval process. There were significant differences in operation time (mean difference [MD]: -28.846, 95% confidence interval [CI: -47.087, -10.604], p = 0.002) and satisfaction rate (odds ratio [OR]: 2.196, 95% CI: [1.061-4. 546]; p = 0.034). However, no significant difference was detected in blood loss (MD: -73.606, 95% CI: [-217.720, 70.509], p = 0.317), hospital stay (MD: -0.512, 95% CI [-1.082, 0.058]; p = 0.079), fusion rate (OR: 0.497, 95% CI [0.079, 3.115]; p = 0.455), visual analog scale (MD: -0.310, 95% CI [-0.433, -0.186]; p < 0.001) or complication rate (risk difference [RD]: -0.140, 95% CI: [-0.378, 0.099]; p = 0.251). Conclusion: Porous TM implants are equally as effective and safe as autograft in anterior cervical discectomy and fusion processes. In addition, porous TM implants could reduce operation time and improve clinical satisfaction significantly.

Abstract
OBJECTIVE Information about postoperative rehabilitation for cervical radiculopathy (CR) is scarce. The aim of this study was to investigate the additional benefits of structured postoperative rehabilitation (SPT), which was performed in all patients, compared with a pragmatic standard postoperative approach (SA), in which rehabilitation was used as needed and patients sought physiotherapy on their own without a referral, in patients with MRI evidence of disc herniation and concomitant clinical signs who underwent surgery for CR. METHODS Patients (n = 202) were randomized to receive SPT or SA. Included key variables in the present study were primary and selected secondary outcomes of a prospective randomized controlled multicenter study. The main outcome was the Neck Disability Index (NDI) score. The NDI score, pain variables, self-efficacy, and health-related quality of life were investigated at baseline and 3, 6, 12, and 24 months postoperatively. RESULTS SPT provided no additional benefits over SA (p = 0.08 to p = 0.99) at the postoperative 2-year follow-up. Both groups improved over time (p < 0.0001), with no reported adverse effects. CONCLUSIONS One can conclude that SPT offered no additional benefits over SA; however, patients tolerated postoperative neck exercises without any negative side effects. These findings are important for the development of future active and neck-specific postoperative rehabilitation interventions for patients with CR.Clinical trial registration no.: NCT01547611 (clinicaltrials.gov).

Physiotherapy after anterior cervical spine surgery for cervical disc disease: study protocol of a prospective randomised study to compare internet-based neck-specific exercise with prescribed physical activity. BMJ Open 2019; 9:e027387. [PMID: 30782952 PMCID: PMC6377535 DOI: 10.1136/bmjopen-2018-027387] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2018] [Revised: 11/12/2018] [Accepted: 11/16/2018] [Indexed: 11/03/2022] Open
Abstract
INTRODUCTION Patients suffering from remaining disability after anterior cervical decompression and fusion (ACDF) surgery for cervical disc disease may be prescribed physical activity (PPA) or neck-specific exercises (NSEs). Currently, we lack data for the success of either approach. There is also a knowledge gap concerning the use of internet-based care for cervical disc disease. The scarcity of these data, and the high proportion of patients with various degrees of incapacity following ACDF, warrant increased efforts to investigate and improve cost-effective rehabilitation. The objective is to compare the effectiveness of a structured, internet-based NSE programme, versus PPA following ACDF surgery. METHODS AND ANALYSIS This is a prospective, randomised, multicentre study that includes 140 patients with remaining disability (≥30% on the Neck Disability Index, NDI) following ACDF for radiculopathy due to cervical disc disease. Patient recruitment occurs following attendance at routine clinical appointments, scheduled at 3 months postsurgery. Patients are then randomised to one of two groups (70 patients/group) for a 3-month treatment programme/period of either internet-based NSE or PPA. Questionnaires on background data, pain and discomfort, physical and mental capacity, satisfaction with care, and health and workplace factors are completed, along with physical measures of neck-related function conducted by independent test leaders blinded to randomisation. Measures are collected at inclusion, after the 3-month treatments (end of treatment) and at a 2-year follow-up. Radiography will be completed at the 2-year follow-up. Preoperative data will be collected from the Swedish Spine Registry. Data on healthcare consumption, drug use and sick leave will be requested from the relevant national registers. ETHICAL CONSIDERATIONS This study was approved by the Regional Ethical Review Board in Linköping Ref. 2016/283-31 and 2017/91- 32. The scientists are independent with no commercial ties. Patients are recruited after providing written informed consent. Patient data are presented at group level such that no connection to any individual can be made. All data are anonymised when reported, and subject to the Swedish Official Secrets Health Acts. The test leaders are independent and blinded for randomisation. Exercises, both general and neck-specific, have been used extensively in clinical practice and we anticipate no harm from their implementation other than a risk of muscle soreness. Both randomisation groups will receive care that is expected to relieve pain, although the group receiving NSE is expected to demonstrate a greater and more cost-effective improvement versu s the PPA group. Any significant harm or unintended effects in each group will be collected by the test leaders. All questionnaires and test materials are coded by the research group, with code lists stored in locked, fireproof file cabinets, housed at the university in a room with controlled (card-based) access. Only individuals in receipt of a unique website address posted by the researchers can access the programme; patients can neither communicate with each other nor with caregivers via the programme.Study participation might lead to improved rehabilitation versus non-participation, and might therefore be of benefit. The results of this study should also contribute to more effective and flexible rehabilitation, shorter waiting times, lower costs and the possibility to implement our findings on a wider level. DISSEMINATION If effective, the protocols used in this study can be implemented in existing healthcare structures. The results of the study will be presented in scientific journals and popular science magazines of relevance to health. The findings will also be presented at local, regional, national and international conferences and meetings, as well as in the education of university students and at public lectures. Information about the results will be communicated to the general population in cooperation with patient organisations and the media. TRIAL REGISTRATION NCT03036007.

Cervical Artificial Disc Replacement Versus Fusion for Cervical Degenerative Disc Disease: A Health Technology Assessment. ONTARIO HEALTH TECHNOLOGY ASSESSMENT SERIES 2019; 19:1-223.

Abstract
BACKGROUND Cervical degenerative disc disease is a multifactorial condition that begins with deterioration of the intervertebral disc and results in further degeneration within the spine involving the facet joints and ligaments. This health technology assessment examined the effectiveness, safety, durability, and cost-effectiveness of cervical artificial disc replacement (C-ADR) versus fusion for treating cervical degenerative disc disease. METHODS We performed a systematic literature search of the clinical evidence comparing C-ADR with fusion. We assessed the risk of bias in each study and the quality of the body of evidence according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group criteria. We performed a systematic review of the economic literature and assessed the cost-effectiveness of C-ADR compared with fusion. We also estimated the budget impact of publicly funding C-ADR in Ontario over the next 5 years. To contextualize the potential value of C-ADR, we spoke with people with cervical degenerative disc disease. RESULTS Eight studies of C-ADR for one-level cervical degenerative disc disease and two studies of C-ADR for two-level disease satisfied the criterion of statistical noninferiority compared with fusion on the primary outcome of 2-year overall treatment success (GRADE: Moderate). In two studies of C-ADR for two-level disease, C-ADR was statistically superior to fusion surgery for the same primary outcome (GRADE: Moderate). C-ADR was also noninferior to fusion for perioperative outcomes (e.g., operative time, blood loss), patient satisfaction, and health-related quality of life (GRADE: Moderate). C-ADR was superior to fusion for recovery and return to work, had higher technical success, and had lower rates of re-operation at the index site (GRADE: Moderate). C-ADR also maintained motion at the index-treated cervical level (GRADE: Moderate), but evidence was insufficient to determine if adjacent-level surgery rates differed between C-ADR and fusion. Current evidence is also insufficient to determine the long-term durability of C-ADR.The primary economic analysis shows that C-ADR is likely to be cost-effective compared with fusion for both one-level ($11,607/quality-adjusted life-year [QALY]) and two-level ($16,782/QALY) degeneration. Various sensitivity and scenario analyses confirm the robustness of the results. The current uptake for one-level and two-level C-ADR in Ontario is about 8% of the total eligible. For one-level involvement, the estimated net budget impact increases from $7,243 (18 procedures) in the first year to $395,623 (196 procedures) in the fifth year following public funding, for a total budget impact over 5 years of $916,326. For two-level involvement, the corresponding values are $5,460 (7 procedures) in the first year and $283,689 (76 procedures) in the fifth year, for an estimated total budget impact of $705,628 over 5 years.People with cervical degenerative disc disease reported that symptoms of pain and numbness can have a negative impact on their quality of life. People with whom we spoke had tried a variety of treatments with minor success; surgery was perceived as the most effective and permanent solution. Those who had undergone C-ADR spoke positively of its impact on their quality of life and ability to move their neck after surgery. The limited availability of C-ADR in Ontario was viewed as a barrier to receiving this treatment. CONCLUSIONS For carefully selected patients with cervical degenerative disc disease, C-ADR provides patient-important and statistically significant reductions in pain and disability. Further, unlike fusion, C-ADR allows people to maintain relatively normal cervical spine motion.Compared with fusion, C-ADR appears to represent good value for money for adults with one-level cervical degenerative disc disease ($11,607/QALY) and for adults with two-level disease ($16,782/QALY). In Ontario, publicly funding C-ADR could result in total additional costs of $916,326 for one-level procedures and $705,628 for two-level procedures over the next 5 years.People with whom we spoke who had undergone C-ADR surgery spoke positively of its impact on their quality of life and ability to move their neck after surgery. The limited availability of C-ADR in Ontario was viewed as a barrier to receiving this treatment.

Abstract
PURPOSE Anterior cervical procedures are associated with many intra- and post-operative complications leading to long-term patient morbidity. In this study, we have evaluated the clinical and radiological Outcome of day care posterior cervical foraminotomy in patients with single-level cervical radiculopathy with or without neurodeficit. MATERIALS AND METHODS Seventeen patients underwent single-level posterior cervical foraminotomy for radicular symptoms were studied between June 2011 and May 2016. Clinical outcome was studied by visual analog scale (VAS) score, neck disability index (NDI), and Odom's criteria. Adjacent segment degeneration was evaluated on lateral cervical radiograph at every follow-up by calculating the focal and global angulation of the cervical spine and disc height at the operated level and adjacent segments. Dynamic lateral cervical spine radiograph was done to evaluate segmental instability. RESULTS After a mean follow-up duration of 30.64 months, 13 patients had excellent, three patients had good, and one patient had fair outcome as per Odom's criteria. The mean VAS score for radicular pain, neck pain, and NDI was significantly reduced postoperatively (P < 0.001). The mean focal angulation, mean global angulation, the disc height at operated and adjacent level were not changed significantly (P > 0.05). There was no instability noted postoperatively on lateral dynamic cervical spine radiographs. There was no complication in our study. CONCLUSION Posterior cervical foraminotomy is an effective surgical method for treatment of patients with single-level cervical radiculopathy and helps to achieve good clinical and radiological outcome, prevents postoperative adjacent segment degeneration and instability with minimal complications.

Eleven-Year Follow-Up of Two Cohorts of Patients Comparing Stand-Alone Porous Tantalum Cage Versus Autologous Bone Graft and Plating in Anterior Cervical Fusions. World Neurosurg 2018; 122:e156-e167. [PMID: 30268546 DOI: 10.1016/j.wneu.2018.09.160] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2018] [Revised: 09/19/2018] [Accepted: 09/20/2018] [Indexed: 12/19/2022]
Abstract
BACKGROUND Anterior cervical discectomy and fusion with a porous tantalum cage is an accepted method to treat degenerated cervical discs, with good results, similar to those with autologous bone graft and plating at short- and mid-term follow-up. However, to date, long-term follow-up studies have been performed. METHODS We performed a retrospective, single-center study to evaluate the outcomes of 2 cohorts from a previous prospective randomized controlled trial comparing stand-alone tantalum cage (group 1, 27 patients) with autologous bone graft and plating (group 2, 30 patients) for single-level anterior cervical discectomy and fusion at 11 years of follow-up. The usual clinical and radiological outcomes and "overall success," proposed by the Food and Drug Administration, were evaluated. RESULTS The improvement in clinical outcomes achieved postoperatively was maintained similarly in the 2 cohorts at 11 years of follow-up. In group 1, the cage had subsided 2-3 mm in 12 patients (44%), segmental lordosis was maintained in 16 patients (59%), adjacent segment degeneration had developed or progressed in 27 of the adjacent segments (50%) in 15 patients (56%), and postoperative nonprogressive deformation of the anterior aspect of the cage was observed in 7 (26%) and minor fragmentation in 3 (11%) patients. In group 2, segmental lordosis was maintained in 90% of the patients and adjacent segment degeneration had developed or progressed in 15 patients (50%). CONCLUSIONS These results show that the clinical and radiological outcomes achieved at mid-term follow-up using a tantalum cage for single-level anterior cervical discectomy and fusion will be maintained for 11 years postoperatively, similar to the results with autologous bone graft and plating.

Abstract
OBJECTIVE Structured physiotherapy has been suggested as treatment before as well as after surgery to improve clinical outcomes in patients with cervical radiculopathy (CR), but randomized clinical trials to inform evidence-based clinical guidelines for the treatment of patients with CR after surgery are lacking. The aim of this study was to compare the results of structured postoperative physiotherapy combining neck-specific exercises with a behavioral approach to a standard postoperative approach in patients who had undergone surgery for cervical disc disease with CR at 6 months after surgery. METHODS Patients with cervical disc disease and persistent CR who were scheduled for surgery were randomized preoperatively to structured postoperative physiotherapy (n = 101) or a standard postoperative approach (n = 100). The latter included pragmatic physiotherapy in accordance with the usual Swedish postoperative care. Outcome measures included patient-reported neck disability as measured with the Neck Disability Index (NDI), intensity and frequency of neck and arm pain, global outcome of treatment, and expectation fulfillment, as well as enablement. RESULTS Patients who received structured postoperative physiotherapy reported greater expectation fulfillment (p = 0.01), and those who attended at least 50% of the treatment sessions reported less neck pain frequency (p = 0.05), greater expectation fulfillment (p = 0.001), and greater enablement (p = 0.04) compared with patients who received the standard postoperative approach. No other difference between treatment groups was found (p > 0.15). The NDI and neck and arm pain intensity were improved in both groups at 6 months after surgery (p < 0.001). Additional use of postoperative physiotherapy was reported by 61% of the patients who received the standard postoperative approach. CONCLUSIONS The results from this first randomized clinical trial of postoperative physiotherapy showed only minor additional benefit of structured postoperative physiotherapy compared with standard postoperative approach 6 months postoperatively in patients who underwent surgery for cervical disc disease with CR. Patients who received structured postoperative physiotherapy reported higher expectation fulfillment, and many patients in the standard postoperative approach group perceived a need for additional treatments after surgery, suggesting that patients with CR are in need of further postoperative support. The results confirm that neck-specific exercises are tolerated postoperatively by patients with CR, but more studies of postoperative physiotherapy are needed to inform clinical guidelines for this patient group.

Abstract
INTRODUCTION Cervical radiculopathy due to discogenic or spondylotic stenosis of the neuroforamen can be surgically treated by an anterior discectomy with fusion (ACDF) or a posterior foraminotomy (FOR). Most surgeons prefer ACDF, although there are indications that FOR is as effective as ACDF, has a lower complication rate and is less expensive. A head-to-head comparison of the 2 surgical techniques in a randomised controlled trial has not yet been performed. The study objectives of the Foraminotomy ACDF Cost-Effectiveness Trial (FACET) study are to compare clinical outcomes, complication rates and cost-effectiveness of FOR to ACDF. METHODS AND ANALYSIS The FACET study is a prospective randomised controlled trial conducted in 7 medical centres in the Netherlands. The follow-up period is 2 years. The main inclusion criterion is a radiculopathy of the C4, C5, C6 or C7 nerve root, due to a single-level isolated cervical foraminal stenosis caused by a soft disc and/or osteophytic component, requiring operative decompression. A sample size of 308 patients is required to test the hypothesis of clinical non-inferiority of FOR versus ACDF. Primary outcomes are: 'operative success', the measured decrease in radiculopathy assessed by the visual analogue scale and 'patient success', assessed by the modified Odom's criteria. Secondary outcomes are: Work Ability Index (single-item WAI), quality of life (EuroQol 5 Dimensions 5 level Survey, EQ-5D-5L), Neck Disability Index (NDI) and complications. An economic evaluation will assess cost-effectiveness. In addition, a budget impact analysis will be performed. ETHICS AND DISSEMINATION Ethical approval was obtained from the Institutional Ethics Committee of the University Medical Center Groningen. Results of this study will be disseminated through national and international papers. The participants and relevant patient support groups will be informed about the results of the study. TRIAL REGISTRATION NUMBER NTR5536, pre-results.

Abstract
Objective The purpose of this study was to evaluate long-term follow-up radiologic/clinical outcomes of patients who underwent anterior cervical discectomy and inter-body fusion (ACDF) with stand-alone cages (SAC) in a single academic institution. Methods Total 99 patients who underwent ACDF with SAC between February 2004 and December 2012 were evaluated retrospectively. A total of 131 segments were enrolled in this study. Basic demographic information, radiographic [segmental subsidence rate, fusion rate, C2–7 global angle, and segmental angle changes)/clinical outcomes (by Odom's criteria and visual analog score (VAS)] and complications were evaluated to determine the long-term outcomes. Results The majority were males (55 vs. 44) with average age of 53.2. Mean follow-up period was 62.9 months. The segmental subsidence rate was 53.4% and fusion rate was 73.3%. In the subsidence group, anterior intervertebral height (AIH) had more tendency of subsiding than middle or posterior intervertebral height (p=0.01). The segmental angle led kyphotic change related to the subsidence of the AIH. Adjacent segmental disease was occurred in 18 (18.2%) patients. Total 6 (6%) reoperations were performed at the index level. There was no statistical significance between clinical and radiological outcomes. But, overall long-term clinical outcome by Odom's criteria was unsatisfactory (64.64%). The neck and arm VAS score were increased by over time. Conclusion Long-term outcomes of ACDF with SAC group were acceptable but not satisfactory. For optimal decision making, more additional comparative long-term outcome data is needed between ACDF with SAC and ACDF with plating.

Abstract
STUDY DESIGN Retrospective review. OBJECTIVE Determine clinical outcomes and cost utility of anterior cervical discectomy and fusion (ACDF) for the treatment of adjacent segment disease (ASD). SUMMARY OF BACKGROUND DATA The incidence of symptomatic ASD after ACDF has been estimated to occur in up to 26% of patients. Commonly, these patients will undergo an additional ACDF procedure. However, there are currently no studies available that adequately describe the clinical outcomes or cost utility of performing ACDF for ASD. METHODS A retrospective review of 40 patients undergoing ACDF for ASD was performed. Baseline and 2-year neck and arm pain (NRS-NP, NRS-AP), neck disability index (NDI), physical and mental quality of life (SF-12 PCS & MCS), and Zung depression score (ZDS) were assessed. Two-year total neck-related medical resource utilization, amount of missed work, and health-state values were determined. Quality-adjusted life years (QALYs) were calculated from EQ-5D assessments with US valuation. Comprehensive costs (indirect, direct, and total cost) and the value (cost-per-QALY gained) of performing ACDF for ASD were assessed. RESULTS Performing ACDF to treat ASD resulted in significant improvements (P<0.05) in NRS-NP, NRS-AP, NDI, SF-12 PCS, and ZDS outcome measures. Patient-reported health states also significantly improved, with a mean cumulative 2-year gain of 0.54 QALYs. The mean 2-year cost of surgery was $32,616 (direct cost: $25,391; indirect cost: $7225). ACDF for the treatment of ASD was associated with a mean 2-year cost per QALY gained of $60,526. CONCLUSIONS Performing ACDF for ASD resulted in significant improvements in patient pain, disability, and quality of life. Further, the mean 2-year cost-per-QALY was determined to be $60,526, which suggests surgical intervention to be cost effective. This study is the first to provide evidence that performing an ACDF for ASD is both clinically and cost effective.

Abstract
Study Design Bibliometric analysis. Objective To determine trends, frequency, and distribution of patient-reported outcome instruments (PROIs) in degenerative cervical spine surgery literature over the past decade. Methods A search was conducted via PubMed from 2004 to 2013 on five journals (The Journal of Bone and Joint Surgery, The Bone and Joint Journal, The Spine Journal, European Spine Journal, and Spine), which were chosen based on their impact factors and authors' consensus. All abstracts were screened and articles addressing degenerative cervical spine surgery using PROIs were included. Articles were then analyzed for publication date, study design, journal, level of evidence, and PROI trends. Prevalence of PROIs and level of evidence of included articles were analyzed. Results From 19,736 articles published, 241 articles fulfilled our study criteria. Overall, 53 distinct PROIs appeared. The top seven most frequently used PROIs were: Japanese Orthopaedic Association score (104 studies), visual analog scale for pain (100), Neck Disability Index (72), Short Form-36 (38), Nurick score (25), Odom criteria (21), and Oswestry Disability Index (15). Only 11 PROIs were used in 5 or more articles. Thirty-three of the PROIs were appeared in only 1 article. Among the included articles, 16% were of level 1 evidence and 32% were of level 4 evidence. Conclusion Numerous PROIs are currently used in degenerative cervical spine surgery. A consensus on which instruments to use for a given diagnosis or procedure is lacking and may be necessary for better communication and comparison, as well as for the accumulation and analysis of vast clinical data across multiple studies.

Abstract
The authors aim to evaluate the ability of spine surgeons to subjectively identify patients with psychological distress in a subset of lumbar fusion candidates, and the influence of such factors on surgical outcomes. From a cohort of 85 patients who had received a surgical indication for lumbar fusion and were subjectively evaluated for psychological distress, 60 were included in the study and underwent objective evaluation using the Distress Risk Assessment Method (DRAM) evaluation for depressive/distress symptoms, VAS and Oswestry scores pre- and postoperatively. Fifty-six patients were available with a minimum 6-month follow-up: 20 presented with normal DRAM scores, and 36 with abnormal DRAM (28 at risk; 4 distressed somatic; 4 distressed depressive). Although the group improved significantly with surgery regarding VAS and Oswestry, it was not the case for the DRAM score. The abnormal DRAM group had inferior VAS, Oswestry and satisfaction rates in comparison with the normal DRAM group. A significant number of patients in the at-risk group reduced their DRAM scores and were classified as normal patients at the end of the study. This study emphasizes the need for objective psychological screening on chronic low back pain patients and that although patients with abnormal DRAM scores benefit from surgery, they report inferior outcomes and satisfaction in comparison with the normal DRAM group.

Abstract
STUDY DESIGN Case report. BACKGROUND Thoracic spine thrust manipulation has been shown to be an effective intervention for individuals experiencing mechanical neck pain. CASE DESCRIPTION The patient was a 46-year-old woman referred to outpatient physical therapy 2 months following multiple-level anterior cervical discectomy and fusion. At initial evaluation, primary symptoms consisted of frequent headaches, neck pain, intermittent referred right elbow pain, and muscle fatigue localized to the right cervical and upper thoracic spine regions. Initial examination findings included decreased passive joint mobility of the thoracic spine, limited cervical range of motion, and limited right shoulder strength. Outcome measures consisted of the numeric pain rating scale, the Neck Disability Index, and the global rating of change scale. Treatment consisted of a combination of manual therapy techniques aimed at the thoracic spine, therapeutic exercises for the upper quarter, and patient education, including a home exercise program, over a 6-week episode of care. OUTCOMES Immediate reductions in cervical-region pain (mean ± SD, 2.0 ± 1.1) and headache (2.0 ± 1.3) intensity were reported every treatment session immediately following thoracic spine thrust manipulation. At discharge, the patient reported 0/10 cervical pain and headache symptoms during all work-related activities. From initial assessment to discharge, Neck Disability Index scores improved from 46% to 16%, with an associated global rating of change scale score of +7 ("a very great deal better"). DISCUSSION This case report describes the immediate and short-term clinical outcomes for a patient presenting with symptoms of neck pain and headache following anterior cervical discectomy and fusion surgical intervention. Clinical rationale and patient preference aided the decision to incorporate thoracic spine thrust manipulation as a treatment for this patient. Level of Evidence Therapy, level 4.

Abstract
Background: The aim of this work is to present a novel decompression technique that approaches cervical spine posteriorly, but through minimal invasive method using tubular retractor avoiding detachment of posterior musculature. Methods: Six patients underwent minimally invasive posterior cervical decompression using the tubular retractor system and surgical microscope. Minimally invasive access to the posterior cervical spine was performed with exposure through a paramedian muscle-splitting approach. With the assistance of a specialized tubular retraction system and deep soft tissue expansion mechanism, multilevel posterior cervical decompression could be accomplished. This approach also allows safe docking of the retractor system on the lateral mass, thus avoiding the cervical spinal canal during exposure. A standard operating microscope was used with ×10 magnification and 400 mm focal length. The hospital charts, magnetic resonance imaging studies, and follow-up records of all the patients were reviewed. Outcome was assessed by neurological status and visual analog scale (VAS) for neck and arm pain. Results: There was no significant complication related to operation. The follow-up time was 4-12 months (mean, 9 months). Muscle weakness improved in all patients; sensory deficits resolved in four patients and improved in two patients. Analysis of the mean VAS for radicular pain and VAS for neck pain showed significant improvement. Conclusions: The preliminary experiences with good clinical outcome seem to promise that this minimally invasive technique is a valid alternative option for the treatment of cervical spondylotic myelopathy.

Abstract
BACKGROUND Many patients with cervical disc disease require leave from work, due to long-lasting, complex symptoms, including chronic pain and reduced levels of physical and psychological function. Surgery on a few segmental levels might be expected to resolve disc-specific pain and reduce neurological deficits, but not the non-specific neck pain and the frequent illness. No study has investigated whether post-surgery physiotherapy might improve the outcome of surgery. The main purpose of this study was to evaluate whether a well-structured rehabilitation programme might add benefit to the customary post-surgical treatment for cervical disc disease, with respect to function, disability, work capability, and cost effectiveness. METHODS/DESIGN This study was designed as a prospective, randomised, controlled, multi-centre study. An independent, blinded investigator will compare two alternatives of rehabilitation. We will include 200 patients of working age, with cervical disc disease confirmed by clinical findings and symptoms of cervical nerve root compression. After providing informed consent, study participants will be randomised to one of two alternative physiotherapy regimes; (A) customary treatment (information and advice on a specialist clinic); or (B) customary treatment plus active physiotherapy. Physiotherapy will follow a standardised, structured programme of neck-specific exercises combined with a behavioural approach. All patients will be evaluated both clinically and subjectively (with questionnaires) before surgery and at 6 weeks, 3 months, 6 months, 12 months, and 24 months after surgery. The main outcome variable will be neck-specific disability. Cost-effectiveness will also be calculated. DISCUSSION We anticipate that the results of this study will provide evidence to support physiotherapeutic rehabilitation applied after surgery for cervical radiculopathy due to cervical disc disease. TRIAL REGISTRATION ClinicalTrials.gov identifier: NCT01547611.

Abstract
There is currently a lack of information regarding neck muscle activity during specific exercises. The purpose of the present study was to investigate deformation and deformation rate in different layers of dorsal and ventral neck muscles during isometric neck muscle contraction in individuals after anterior cervical decompression and fusion and in healthy controls. This study included 10 individuals (mean age 60 years; SD 7.1) with a verified, long-standing neck disorder and 10 healthy, age- and sex-matched controls. Ultrasonography and post-process speckle tracking analysis was used to investigate the degree and the rate of neck muscles motions at the C4 segmental level during sub-maximal, isometric resistance of the head in a seated position. None of the analyses performed showed significant differences between groups (p > 0.05). In the dorsal muscles, both groups exhibited a higher deformation rate in the multifidus than in the trapezius, splenius, and semispinalis capitis (p ≤ 0.01). In the neck disorder group, the multifidus also showed a higher deformation rate compared to the semispinalis cervicis (p = 0.02). In the ventral muscles of patients with neck disorders, the longus colli had a higher deformation rate than the sternocleidomastoid (p = 0.02). Among the healthy controls, the multifidus showed a higher degree of deformation (p = 0.02) than the trapezius. In conclusion, our results showed no significant differences between the two groups in mechanical neck muscle activation. Larger studies with different exercises, preferably with a standardized measure of resistance, are needed to investigate whether patients and controls show differences in deformation and deformation rates in neck muscles.

Abstract
Objective Autologous bone graft with anterior plating had been a standard method for anterior cervical discectomy and fusion (ACDF). Drawbacks of a standard method were donor site problem and problem associated with anterior plate. The stand-alone cage was introduced to reduce such problems. However, problems associated with subsidence and local kyphosis at the index level (segmental kyphosis) still persist with stand-alone cage and a standard method would be required in some cases. It seems that harvest of autologous bone and anterior plating procedure is time consuming, but this has not been verified. The aim of this study was to compare the operating time between patients operated on with stand-alone cage versus a standard method for single-level cervical disc disease. Methods Consecutive 29 patients (M:F=18:11; mean age, 58.4±12.4 years), who had undergone ACDF for single-level disc disease by a single surgeon from incision to closure during 2009-2011, were selected for this retrospective study. Seventeen patients were operated with stand-alone cage (Group I), and twelve patients were with a standard method (Group II). Operating time (from incision to closure), estimated blood loss, clinical and radiological outcomes were compared. Follow-up period was 11.4±6.3 months. Results Operating time was not different between groups longer; Group I (96.1±28.7 minutes) and Group II (112.4±31.7 minutes) (p=0.13). There was no surgery related complication. Excellent or good outcome was achieved in 11 and 10 patients of group I and II, respectively. Bony fusion was achieved in 15 and 10 patients of group I and II respectively, while one subsidence occurred in each group. Postoperative segmental angle at the index level and cervical curvature was not different between groups. No patient complained donor site pain at the last follow-up. Conclusions ACDF with a standard method for single-level cervical disc disease was not a time-consuming procedure comparing stand-alone cage.

Abstract
Object
The primary purpose of this study was to analyze what effect preoperative patient expectations and 36-Item Short Form Health Survey (SF-36) Mental Component Summary (MCS) scores have on clinical outcomes. To the authors' knowledge, there are no prospective studies that have examined the effects of both preoperative pain expectations and SF-36 MCS scores on clinical outcomes and satisfaction with results following anterior cervical discectomy and fusion (ACDF).
Methods
This study analyzed 79 patients (38 men, 41 women) undergoing 1- to 3-level ACDF surgery. Preoperatively, patients were divided into 2 groups for the expectation analyses: patients who expected complete resolution of pain postoperatively (44 total) and those who expected some residual pain (35 total) postoperatively. Preoperative SF-36 MCS scores were used to test the possible effects of mental health on clinical outcomes and satisfaction. Clinical outcomes were evaluated using visual analog scales (VASs) for neck/arm pain, Neck Disability Index (NDI), SF-36 Physical Component Summary (PCS)/MCS, and patient satisfaction with results scales. The mean follow-up duration was 38.8 months (range 7–59 months).
Results
All postoperative measures depicted significant improvement overall. Patients who expected no pain reported lower postoperative neck/arm pain scores (p < 0.02), higher SF-36 MCS scores (p = 0.04), and higher satisfaction with results scores (p = 0.01) compared with patients who expected some pain, after controlling for their respective preoperative scores. Higher preoperative SF-36 MCS scores predicted significantly lower postoperative neck pain (p = 0.003) and NDI (p = 0.004) scores, as well as higher postoperative SF-36 PCS (p = 0.002), SF-36 MCS (p = 0.001), and satisfaction (p = 0.03) scores, after controlling for their respective preoperative scores.
Conclusions
Patients who expected no pain postoperatively reported better scores on the nonstandardized outcome measure scales (VAS arm/neck, satisfaction with results), and higher SF-36 MCS scores. Higher preoperative MCS scores were related to better overall (standardized and nonstandardized) clinical outcomes (VAS neck, NDI, SF-36 PCS/MCS, and satisfaction with results). The results suggest that optimism in patients' expectations as well as mental well-being are related to improved clinical outcomes and higher patient satisfaction.

Abstract
STUDY DESIGN A systematic review of randomized controlled trials. OBJECTIVE To determine which technique of anterior cervical interbody fusion (ACIF) gives the best outcome in patients with cervical degenerative disc disease. SUMMARY OF BACKGROUND DATA The number of surgical techniques for decompression and ACIF as treatment for cervical degenerative disc disease has increased rapidly, but the rationale for the choice between different techniques remains unclear. METHODS From a comprehensive search, we selected randomized studies that compared anterior cervical decompression and ACIF techniques, in patients with chronic single- or double-level degenerative disc disease or disc herniation. Risk of bias was assessed using the criteria of the Cochrane back review group. RESULTS Thirty-three studies with 2267 patients were included. The major treatments were discectomy alone and addition of an ACIF procedure (graft, cement, cage, and plates). At best, there was very low-quality evidence of little or no difference in pain relief between the techniques. We found moderate quality evidence for few secondary outcomes. Odom's criteria were not different between iliac crest autograft and a metal cage (risk ratio [RR]: 1.11; 95% confidence interval [CI]: 0.99-1.24). Bone graft produced more fusion than discectomy (RR: 0.22; 95% CI: 0.17-0.48). Complication rates were not different between discectomy and iliac crest autograft (RR: 1.56; 95% CI: 0.71-3.43). Low-quality evidence was found that iliac crest autograft results in better fusion than a cage (RR: 1.87; 95% CI: 1.10-3.17); but more complications (RR: 0.33; 95% CI: 0.12-0.92). CONCLUSION When fusion of the motion segment is considered to be the working mechanism for pain relief and functional improvement, iliac crest autograft appears to be the golden standard. When ignoring fusion rates and looking at complication rates, a cage as a golden standard has a weak evidence base over iliac crest autograft, but not over discectomy.

Abstract
BACKGROUND The number of surgical techniques for decompression and solid interbody fusion as treatment for cervical spondylosis has increased rapidly, but the rationale for the choice between different techniques remains unclear. OBJECTIVES To determine which technique of anterior interbody fusion gives the best clinical and radiological outcomes in patients with single- or double-level degenerative disc disease of the cervical spine. SEARCH STRATEGY We searched CENTRAL (The Cochrane Library 2009, issue 1), MEDLINE (1966 to May 2009), EMBASE (1980 to May 2009), BIOSIS (2004 to May 2009), and references of selected articles. SELECTION CRITERIA Randomised comparative studies that compared anterior cervical decompression and interbody fusion techniques for participants with chronic degenerative disc disease. DATA COLLECTION AND ANALYSIS Two review authors independently assessed risk of bias using the Cochrane Back Review Group criteria. Data on demographics, intervention details and outcome measures were extracted onto a pre-tested data extraction form. MAIN RESULTS Thirty-three small studies ( 2267 patients) compared different fusion techniques. The major treatments were discectomy alone, addition of an interbody fusion procedure (autograft, allograft, cement, or cage), and addition of anterior plates. Eight studies had a low risk of bias. Few studies reported on pain, therefore, at best, there was very low quality evidence of little or no difference in pain relief between the different techniques. We found moderate quality evidence for these secondary outcomes: no statistically significant difference in Odom's criteria between iliac crest autograft and a metal cage (6 studies, RR 1.11 (95% CI 0.99 to1.24)); bone graft produced more effective fusion than discectomy alone (5 studies, RR 0.22 (95% CI 0.17 to 0.48)); no statistically significant difference in complication rates between discectomy alone and iliac crest autograft (7 studies, RR 1.56 (95% CI 0.71 to 3.43)); and low quality evidence that iliac crest autograft results in better fusion than a cage (5 studies, RR 1.87 (95% CI 1.10 to 3.17)); but more complications (7 studies, RR 0.33 (95% CI 0.12 to 0.92)). AUTHORS' CONCLUSIONS When the working mechanism for pain relief and functional improvement is fusion of the motion segment, there is low quality evidence that iliac crest autograft appears to be the better technique. When ignoring fusion rates and looking at complication rates, a cage has a weak evidence base over iliac crest autograft, but not over discectomy alone. Future research should compare additional instrumentation such as screws, plates, and cages against discectomy with or without autograft.

Abstract
Prospective case series studies have shown that plasma disc decompression (PDD) using the COBLATION SpineWand device (ArthroCare Corporation, Austin, TX) is effective for decompressing the disc nucleus in symptomatic contained cervical disc herniations. This prospective, randomized controlled clinical trial was conducted to evaluate the clinical outcomes of percutaneous PDD as compared to conservative care (CC) through 1 year. Patients (n = 115) had neck/arm pain >50 on the visual analog scale (VAS) pain scale and had failed at least 30 days of failed CC. Patients were randomly assigned to receive either PDD (n = 62) or CC (n = 58). Clinical outcome was determined by VAS pain score, neck disability index (NDI) score, and SF-36 health survey, collected at 6 weeks, 3 months, 6 months, and 1 year. The PDD group had significantly lower VAS pain scores at all follow-up time points (PDD vs. CC: 6 weeks, -46.87 +/- 2.71 vs. -15.26 +/- 1.97; 3 months, -53.16 +/- 2.74 vs. -30.45 +/- 2.59; 6 months, -56.22 +/- 2.63 vs. -40.26 +/- 2.56; 1 year, -65.73 +/- 2.24 vs. -36.45 +/- 2.86; GEE, P < 0.0001). PDD patients also had significant NDI score improvement over baseline when compared to CC patients at the 6 weeks (PDD vs. CC: -9.15 +/- 1.06 vs. -4.61 +/- 0.53, P < 0.0001) and 1 year (PDD vs. CC: -16.70 +/- 0.29 vs. -12.40 +/- 1.26, P = 0.005) follow-ups. PDD patients showed statistically significant improvement over baseline in SF-36 physical component summary scores when compared to CC patients at 6 weeks and 1 year (PDD vs. CC: 8.86 + 8.04 vs. 4.24 +/- 3.79, P = 0.0004; 17.64 +/- 10.37 vs. 10.50 +/- 10.6, P = 0.0003, respectively). In patients who had neck/arm pain due to a contained cervical disc herniation, PDD was associated with significantly better clinical outcomes than a CC regimen. At 1 year, CC patients appeared to suffer a "relapse, showing signs of decline in most measurements, whereas PDD patients showed continued stable improvement.

Abstract
OBJECT The objective of this systematic review was to use evidence-based medicine to identify the best techniques for anterior cervical nerve root decompression. METHODS The National Library of Medicine and Cochrane Database were queried using MeSH headings and keywords relevant to techniques for the surgical management of cervical radiculopathy. The guidelines group assembled an evidentiary table summarizing the quality of evidence (Classes I-III). The group formulated recommendations that contained the degree of strength based on the Scottish Intercollegiate Guidelines network. Validation was done through peer-review by the Joint Guidelines Committee of the American Association of Neurological Surgeons/Congress of Neurological Surgeons. RESULTS Both anterior cervical discectomy (ACD) and anterior cervical discectomy with fusion (ACDF) are equivalent treatment strategies for 1-level disease with regard to functional outcome (Class II). Anterior cervical discectomy with fusion may achieve a more rapid reduction of neck and arm pain compared to ACD with a reduced risk of kyphosis, although functional outcomes may be similar. Anterior cervical discectomy with fusion is not a lasting means of increasing foraminal or disc height compared to ACD. Anterior cervical plating (ACDF with instrumentation) improves arm pain (but not other clinical parameters) better than ACDF in the treatment of 2-level disease (Class II). With respect to 1-level disease, plating may reduce the risk of pseudarthrosis and graft problems (Class III) but does not necessarily improve clinical outcome alone (Class II). Cervical arthroplasty is recommended as an alternative to ACDF in selected patients for control of neck and arm pain (Class II). CONCLUSIONS Anterior cervical discectomy, ACDF, and arthroplasty are effective techniques for addressing surgical cervical radiculopathy.

Abstract
A prospective, randomized, controlled study was carried out to compare the radiological and clinical outcomes after anterior cervical decompression and fusion (ACDF) with Trabecular Metal (TM) to the traditional Smith-Robinson (SR) procedure with autograft. The clinical results of cervical fusion with autograft from the iliac crest are typically satisfactory, but implications from the donor site are frequently reported. Alternative materials for cervical body interfusion have shown lower fusion rates. Trabecular Metal is a porous tantalum biomaterial with structure and mechanical properties similar to that of trabecular bone and with proven osteoconductivity. As much as 80 consecutive patients planned for ACDF were randomized for fusion with either TM or tricortical autograft from the iliac crest (SR) after discectomy and decompression. Digitized plain radiographic images of 78 (98%) patients were obtained preoperatively and at 2-year follow-up and were subsequently evaluated by two senior radiologists. Fusion/non-fusion was classified by visual evaluation of the A-P and lateral views in forced flexion/extension of the cervical spine and by measuring the mobility between the fused vertebrae. MRI of 20 TM cases at 2 years was successfully used to assess the decompression of the neural structures, but was not helpful in determining fusion/non-fusion. Pain intensity in the neck, arms and pelvis/hip were rated by patients on a visual analog scale (VAS) and neck function was rated using the Neck Disability Index (NDI) the day before surgery and 4, 12 and 24 months postoperatively. Follow-ups at 12 and 24 months were performed by an unbiased observer, when patients also assessed their global outcome. Fusion rate in the SR group was 92%, and in the TM group 69% (P < 0.05). The accuracy of the measurements was calculated to be 2.4 degrees . Operating time was shorter for fusion with TM compared with autograft; mean times were 100 min (SD 18) and 123 min (SD 23), respectively (P = 0.001). The patients' global assessments of their neck and arm symptoms 2 years postoperatively for the TM group were rated as 79% much better or better after fusion with TM and 75% using autograft. Pain scores and NDI scores were significantly improved in both groups when compared with baseline at all follow-ups, except for neck pain at 1 year for the TM group. There was no statistically significant difference in clinical outcomes between fusion techniques or between patients who appeared radiologically fused or non-fused. There was no difference in pelvic/hip pain between patients operated on with or without autograft. In our study, Trabecular Metal showed a lower fusion rate than the Smith-Robinson technique with autograft after single-level anterior cervical fusion without plating. There was no difference in clinical outcomes between the groups. The operative time was shorter with Trabecular Metal implants.

Abstract
PURPOSE There is no knowledge if short-term outcome in patients after anterior cervical decompression and fusion (ACDF) can be used to identify which patients have remaining deficit in long term. This study investigates if 6-month outcome with a broad assessment after ACDF with a cervical intervertebral fusion cage can be a guide for the 3-years outcome. METHOD A prospective study. Questions about background data, pain, numbness, neck specific disability, distress, sick leave, health, symptom satisfaction and effect of and satisfaction with surgery were asked 28 patients 3 years after ACDF. Measurements have earlier been obtained before and 6 and 12 months after ACDF. RESULTS Compared with the results before surgery patients had improved in pain intensity (p = 0.001), neck pain (0.001), numbness (p = 0.02) and were more 'satisfied' with having their neck problems (p = 0.01). Except for a worsening in expectations of surgery fulfilled (p = 0.04) there were no significant differences between 6-month and 3-year outcome. Three years after ACDF about two-thirds of the patients had remaining deficit with regard to pain intensity, Neck Disability Index, Distress and Risk Assessment Method and general health. According to the parameters studied 50 - 78% of those who at the 6-month follow-up were without deficit were still healthy at the 3-year follow-up. For patients with deficit at 6-month follow-up, still 83 - 100% had deficit 3 years after surgery. CONCLUSIONS Despite a rather small study obtained the stability of 6-month and 3-year results indicates that short-term results might be sufficient for evaluating effects of the treatment. Since the patients in this study clearly demonstrate broad problems array of development of more structured multi-professional rehabilitation models including exercises which improve neck muscle strength, endurance and proprioception need to be introduced.

Abstract
STUDY DESIGN Best evidence synthesis. OBJECTIVE To identify, critically appraise, and synthesize literature from 1980 through 2006 on surgical interventions for neck pain alone or with radicular pain in the absence of serious pathologic disease. SUMMARY OF BACKGROUND DATA There have been no comprehensive systematic literature or evidence-based reviews published on this topic. METHODS We systematically searched Medline for literature published from 1980 to 2006 on percutaneous and open surgical interventions for neck pain. Publications on the topic were also solicited from experts in the field. Consensus decisions were made about the scientific merit of each article; those judged to have adequate internal validity were included in our Best Evidence Synthesis. RESULTS Of the 31,878 articles screened, 1203 studies were relevant to the Neck Pain Task Force mandate and of these, 31 regarding treatment by surgery or injections were accepted as scientifically admissible. Radiofrequency neurotomy, cervical facet injections, cervical fusion and cervical arthroplasty for neck pain without radiculopathy are not supported by current evidence. We found there is support for short-term symptomatic improvement of radicular symptoms with epidural corticosteroids. It is not clear from the evidence that long-term outcomes are improved with the surgical treatment of cervical radiculopathy compared to nonoperative measures. However, relatively rapid and substantial symptomatic relief after surgical treatment seems to be reliably achieved. It is not evident that one open surgical technique is clearly superior to others for radiculopathy. Cervical foramenal or epidural injections are associated with relatively frequent minor adverse events (5%-20%); however, serious adverse events are very uncommon (<1%). After open surgical procedures on the cervical spine, potentially serious acute complications are seen in approximately 4% of patients. CONCLUSION Surgical treatment and limited injection procedures for cervical radicular symptoms may be reasonably considered in patients with severe impairments. Percutaneous and open surgical treatment for neck pain alone, without radicular symptoms or clear serious pathology, seems to lack scientific support.

Abstract
Object
Although the clinical outcomes following anterior cervical discectomy and fusion (ACDF) surgery are generally good, 2 major complications are graft migration and nonunion. These complications have led some to advocate rigid internal fixation and/or cervical immobilization postoperatively. This paper examines a single-surgeon experience with single-level ACDF without use of plates or hard collars in patients with degenerative spondylosis in whom allograft was used as the fusion material.
Methods
The authors conducted a retrospective review of a prospective database of (Cloward-type) ACDF operations performed by the senior author (J.A.J.) between July 1996 and June 2005. Radiographic follow-up included static and flexion/extension radiographs obtained to assess fusion, focal and segmental kyphosis, and change in disc space height. At most recent follow-up, the patients' condition was evaluated by an independent physician examiner. The Odom criteria and Neck Disability Index (NDI) were used to assess outcome.
Results
One hundred seventy patients underwent single-level ACDF for degenerative pathology during the study period. Their most common presenting symptoms were pain, weakness, and radiculopathy; 88% of patients noted ≥ 2 neurological complaints. The mean hospital stay was 1.76 days (range 0–36 days), and 3 patients (2%) had major immediate postoperative complications requiring reoperation. The mean duration of follow-up was 22 months (range 12–124 months). Radiographic evidence of fusion was present in 160 patients (94%). Seven patients (4%) showed radiographic evidence of pseudarthrosis, and graft migration was seen in 3 patients (2%). All patients had increases in focal kyphosis at the operated level on postoperative radiographs (mean −7.4°), although segmental alignment was preserved in 133 patients (78%). Mean change in disc space height was 36.5% (range 28–53%). At most recent clinical follow-up, 122 patients (72%) had no complaints referable to cervical disease and were able to carry out their activities of daily living without impairment. The mean postoperative NDI score was 3.2 (median 3, range 0–31).
Conclusions
Single-level ACDF without intraoperative plate placement or the use of a postoperative collar is an effective treatment for cervical spondylosis. Although there is evidence of focal kyphosis and loss of disc space height, radiographic evidence of fusion is comparable to that attained with plate fixation, and the rate of clinical improvement is high.

Abstract
STUDY DESIGN A prospective randomized controlled study was carried out. OBJECTIVE To determine the effectiveness and safety of a tantalum implant in achieving anterior cervical fusion following 1-level discectomy as treatment of degenerative cervical disc disease with radiculopathy. SUMMARY OF BACKGROUND DATA The gold standard for the treatment of degenerative cervical disc disease could not be already identified. The morbidity of autologous graft and plating, and the doubt about the mechanical efficacy of plate fixation and the clinical benefits in 1-level fusion have promoted the use of other constructs. METHODS Sixty-one patients were randomized to anterior cervical discectomy and fusion with interbody implant of tantalum (n = 28) or by means of autologous iliac bone graft and plating (n = 33). Fusion rate and segmental height and alignment were blind assessed by radiographs by 2 independent reviewers. Clinical status was evaluated using pain visual analogue scale, the Neck Disability Index, and the Zung Depression Scale. Patient's subjective satisfaction was recorded. Complications and operative parameters were also taken into account. RESULTS With an endpoint of 24 months, radiologic and clinical outcomes were similar for both treatments without significant difference. The safety of fusion with tantalum implant was obvious, based on the analysis of complications. Complication rate was considerably higher for the autologous graft plus plating procedure than for implant tantalum (P < 0.005). CONCLUSION The efficacy to achieve fusion after 1-level anterior cervical discectomy, with a good radiologic and clinical outcome, using tantalum implant is equivalent to that of autologous graft and anterior plate, being safer as avoids donor-site graft harvesting and plating complications.

Predictive factors for long-term outcome of anterior cervical decompression and fusion: a multivariate data analysis. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2007; 17:406-414.

Abstract
We conducted a prospective randomized study to investigate predictive factors for short- and long-term outcome of anterior cervical decompression and fusion (ACDF) as measured by current pain intensity on the Visual Analogue Scale (VAS) and by disability using the Neck Disability Index (NDI). Current understanding about how preoperative and short-term outcome data predict long-term outcome is sparse, and there are few studies involving analysis of short-term follow-up using multivariate approaches with quantification of the relative importance of each variable studied. A total of 95 patients were randomly allocated for ACDF with the cervical intervertebral fusion cage or the Cloward procedure. The mean follow-up time was 19 months (range 12-24) for short-term follow-up and 76 months (range 56-94 months) for long-term. Background factors, radiologically detected findings, physiological measurements, treatment type, pain, and disability were used as potential predictors. Multivariate statistical analysis by projection to latent structures was used to investigate predictors of importance for short- and long-term outcome of ACDF. A "preoperative" low disability and pain intensity, non-smoking status, male sex, good hand strength, and an active range of motion (AROM) in the neck were significant predictors for good short- and long-term outcomes. The short-term outcome data were better at predicting long-term outcome than were baseline data. Radiologically detected findings and surgical technique used were mainly insignificant as predictors. We suggest that the inclusion criteria for ACDF should be based on a bio-psycho-social model including NDI. NDI may also be regarded as an important outcome measurement in evaluation of ACDF.

Abstract
Object
In a double-blind randomized study, platelet concentrate was used to treat 50 patients who underwent anterior cervical fusion with allograft bone and internal fixation, predominantly for degenerative disc disease or soft herniated cervical disc. The goal in this study was to compare the outcomes in patients treated with and without the platelet gel.
Methods
Patients were assessed radiographically at 6, 12, and 52 weeks and at 2 years if needed. Clinically, patients were evaluated with the visual analog scale, Neck Disability Index, Short Form–36, and a modified Prolo Scale.
Results
Follow-up included 90% of the patients at 1 year and 84% at 2 years. The overall fusion rate was 84%.
Conclusions
Whereas patients with degenerative discs treated with platelet gel demonstrated early fusion at the 12-week follow-up interval, no consistent early fusion was obtained with the use of the platelet gel preparation in patients with a soft disc herniation.

Abstract
The objectives of the prospective randomized study are to investigate the clinically relevant change after anterior cervical decompression and fusion (ACDF) using measures of pain intensity (visual analog scale, VAS) and neck disability index (NDI). And to determine the number of subjects showing persistent pain and disability at 6-year follow-up. To investigate the possibility of differences in outcome between ACDF with the cervical intervertebral fusion cage (CIFC) and the Cloward procedure (CP). Clinically relevant change and residual, postoperative pain intensity and disability after ACDF have been investigated a little. Ninety-five patients with neck and radicular arm pain lasting for at least 6 months were randomly selected to receive ACDF with the CP or the CIFC. Questionnaires concerning pain and NDI were obtained from 83 patients (87%) at a mean follow-up time of 76 months (range 56-94 months). When evaluating clinical benefits regarding pain intensity 6 years after ACDF, according to different cut-off points and relative percentages, symptoms improved in 46-78% of patients. Improvement in NDI was seen in 18-20% of patients. Approximately 70% of the patients had persistent pain and disability at 6-year follow-up. There was no clinically important difference following CP versus CIFC. Thirty millimeter and 20% in pain intensity and NDI, respectively, are reasonable criteria to suggest a clinically relevant change after ACDF. Before patients undergo ACDF, they should be informed that they have an approximate 50% probability of achieving pain relief and little probability of functional improvement. The findings demonstrate that there is poor evidence for difference between CIFC and CP.

Abstract
A prospective randomised study. To compare the long-term outcome of anterior cervical decompression and fusion (ACDF) with a cervical intervertebral fusion cage (CIFC) and the Cloward procedure (CP). We have previously shown that the 2 year outcome of ACDF with the CIFC is the same as for the CP. The fusion rate in CIFC group was, however, only 55%, compared to 85% in CP group. The long-term outcome of CIFC is poorly documented. Ninety-five patients with at least 6 months duration of neck pain and radicular arm pain were randomly allocated for ACDF with the CIFC or the CP. Radiographs were obtained at 2 years. Questionnaires about pain, disability (Neck Disability Index, NDI), distress, quality of life and global outcome were obtained from 83 patients (87%) (43 CIFC, 40 CP) at a mean follow-up time of 6 years (range 56-94 months). There were no significant differences in any outcome variable between the two treatments. For both CP and CIFC the pain intensity improved (P<0.0001) whereas the NDI was unchanged at long-term follow-up compared to preoperatively. In the CIFC group patients with a healed fusion had significantly less mean pain (24 mm) and NDI (26%) than patients with pseudarthrosis (42 and 41, respectively). Furthermore, the mean pain and NDI reported by CIFC patients with a healed fusion was significantly less than in healed CP patients (37 and 38, respectively). The long-term outcome is the same for the CIFC and the CP, with similar improvements of pain but with considerable remaining functional disability. However, in the subgroup of patients with healed CIFC the outcome was clearly better than for the non-healed CIFC group, and also clearly better than for the healed CP group. Thus, if the healing problem associated with the CIFC can be solved the results indicate that a better outcome can be expected with the cage than with the CP.

Abstract
BACKGROUND Predictive factors for a low arm and neck pain, and good health after anterior cervical decompression and fusion (ACDF) with a cervical carbon fibre intervertebral fusion cage (CIFC) are still lacking. METHOD A prospective consecutive study to investigate which preoperative factors that could predict a good outcome with regard to arm pain, neck pain, Neck Disability Index (NDI) and general health three years after ACDF with CIFC was conducted. Thirty-four patients were included before surgery. Measurements took place the day before, six months, one year and three years after ACDF. FINDINGS In multivariate analysis, to be a non-smoker before surgery was the most important factor for a low postoperative arm pain, a low pain frequency was the most important factor for low postoperative neck pain, normal rating on Distress and Risk Assessment Method (DRAM) was the most important factor for high function on NDI and a low initial pain intensity was the most important factor for good postoperative health. For all outcome variables a normal rating on DRAM was an important factor for a good outcome. CONCLUSIONS Non-smoking, a low pain level and normal rating on DRAM were the best preoperative predictors of a good outcome in ACDF. Inclusion criteria for surgery should be based on a bio psychosocial model and DRAM seems to be useful for including the traditional inclusion criteria.

Abstract
A literature review of the most widely used condition specific, self administered assessment questionnaires for low back pain had been undertaken. General and historic aspects, reliability, responsiveness and minimum clinically important difference, external validity, floor and ceiling effects, and available languages were analysed. These criteria, however, are only part of the consideration. Of similar importance are the content, wording of questions and answers in each of the six questionnaires and an analysis of the different score results. The issue of score bias is discussed and suggestions are given in order to increase the construct validity in the practical use of the individual questionnaires.

Abstract
PURPOSE After an anterior cervical discectomy, immobility at the fused level may increase stress on adjacent disc spaces and causes disc degeneration in 92% of the cases with clinical manifestations in 25.6% of the patients within 10 years. The cervical disk prosthesis may help to prevent this problem. The Bryan prosthesis (Medtronic Sofamor Danek) is currently available in France after a European pilot study. METHODS Since January 2002, 8 patients (9 implants) (mean age: 35 years) were operated on with a prosthesis implantation for disc degeneration after an adjacent previous interbody fusion in 2 patients and for disc herniation or spondylosis in 6 patients. The prosthesis were implanted at the C4-C5 level (one patient), C5-C6 (four patients), and C6-C7 (four patients). Post-operative radiological evaluations with dynamic X-rays and clinical status (Odom questionnaire) were analyzed. RESULTS Surgical procedures, which were longer than the classical technique, were uneventful. Radicular pain resolved after surgery with excellent results with the Odom's score. With a mean follow-up of 12 months, the prosthesis mobility was 8.9 degrees . But one fusion of an implant was encountered 6 months after implantation. CONCLUSIONS The general follow-up for the Bryan(R) cervical disc prosthesis implantation is still too short (2 years) for a definitive evaluation. If clinical results on pain are as good as expected, long-term mobility of the prosthesis has to be checked, as it is the main advantage over classical anterior cervical discectomy with fusion. Patient selection has to be considered.

Abstract
STUDY DESIGN The authors conducted a cross-sectional study. OBJECTIVE Integrated assessment of adjacent instability (AI), myelocompression (MC), magnetic resonance imaging (MRI) signs of myelopathy (MRISM), physician-assessed clinical signs and symptoms, including clinical signs of myelopathy (CSM), patients' self-reported symptoms and quality of life after anterior cervical discectomy and fusion (ACDF). MATERIALS AND METHODS Fifty-four patients who had ACDF between 1986 and 1995 received MRI scans, conventional and flexion/extension radiographs to assess myelocompression, MRISM, fusion, and AI. Clinical outcome was assessed using signs and symptoms based on selected items of Odom's criteria, Oswestry low back pain disability questionnaire, and the neck disability index. Patients reported their quality of life (QL) on a standardized instrument (Profiles of QL of Chronically Ill [PLC]) and by a specific validated Cervical Spine Symptom Scale (CSSS). RESULTS Myelocompression was found more frequently than expected (24%). MRISM were seen in 2 patients (4%). One of the 2 patients developed CSM. Fusion was achieved in 94% (with kyphosis in 17%). AI was found in 30%. However, only myelocompression but not AI was associated with statistically significant decreases in most QL scores (i.e., everyday capabilities, positive mood) and high cervical spine symptom burden (all P's < 0.05). CONCLUSIONS The study results underline the need for a better understanding of the biomechanical changes in the adjacent unfused segments. Consensus is needed on postoperative follow-up guidelines, including pain management strategies. Future studies on the outcome of ACDF will profit from an integrated outcome approach, including assessments based on imaging, physicians, and patients.

Abstract
BACKGROUND The number of surgical techniques for decompression and solid interbody fusion as a treatment for cervical spondylosis has increased rapidly, but the rationale for the choice between different techniques is unclear. OBJECTIVES The goal of this study was to determine which method of anterior cervical interbody fusion at a single or double-level provides the best clinical and radiological outcome in patients with degenerative disc disease. SEARCH STRATEGY Studies were identified with a computer-assisted search of electronic databases in the Cochrane Central Register of Controlled Trials (Issue 1, 2004), MEDLINE (1966 to 2004), EMBASE (1980 to 2004), and Current Contents (1996 to 2004). We also searched references of selected articles. SELECTION CRITERIA With the aid of a checklist, two reviewers independently screened the identified references. Consensus was reached through negotiation. A third reviewer was consulted if consensus could not be reached. Inclusion criteria included: articles were reports of randomised comparative studies; treatments compared anterior cervical decompression and interbody fusion techniques, participants were individuals scheduled for surgery for a chronic (longer than 12 weeks) diagnosis of degenerative disc disease. DATA COLLECTION AND ANALYSIS Methodological quality was assessed independently by two reviewers, using the van Tulder list of criteria. With the aid of a data extraction form, data was extracted independently by two reviewers on group characteristics, intervention details and outcome measures. MAIN RESULTS Fourteen studies with 939 patients evaluated three comparisons of different fusion techniques. From these comparisons it appears that discectomy alone has a shorter operation time, hospital stay, and post-operative absence from work than discectomy with fusion, while there is no statistical difference for pain relief and rate of fusion. It also appears that fusion techniques that use autograft give a better chance for fusion than interbody fusion techniques that use a cage, but other outcome variables could not be combined. REVIEWERS' CONCLUSIONS The low quality of the trials prohibits extensive conclusions from this review. More studies with better methodology and reporting are needed. There should be a more general agreement between researchers on which outcome parameters should be used in the evaluation of anterior cervical fusion procedures.

Abstract
A literature review of the nine most widely used, condition-specific, self-administered assessment questionnaires for low back pain has been undertaken. General and historic aspects, reliability, responsiveness and minimum clinically important difference, external validity, floor and ceiling effects and available languages were analysed for the nine most-used outcome tools. When considering which condition-specific measure to employ, the present overview on assessment tools should provide the necessary information to define the technical aspects of the nine questionnaires. These criteria, however, are only part of the consideration. In part II the construction of these scales in relationship to the measurement domains will be evaluated.

Abstract
BACKGROUND Dorsal foraminotomy is a standard operative procedure for lateral cervical disc herniation. Factors associated with surgical complications and clinical outcome in dorsal foraminotomy of cervical disc herniation were evaluated in a retrospective cohort study. METHOD Thirty-nine patients were operated upon for unilateral, monosegmental, mediolateral cervical disc herniation (+/- associated spondylosis) from 1997 to 1999. Preoperative radiologic imaging and surgical reports were analyzed. Motor disfunction, neck irritation, and radicular pain were evaluated. Outcome was ranked according to modified Odom's criteria at 6 weeks and 1 year postoperatively. RESULTS Six weeks after injury 7 of 39 patients (18%) showed neck irritation. No new neurologic deficit was seen. All patients with preoperative paresis improved; two had early relapses of a medial soft disc prolapse (2/39). Residual radicular pain was seen in 3 of 39 patients (8%) within 30 days postoperatively, necessitating surgical revision. Factors of surgical failure were associated spondylosis (2/3) and residual mediolateral disc protrusion (1/3). In one patient with associated spondylosis, local pain due to a symptomatic fracture of the lateral process of D1 resolved after revision. Duration of preoperative radicular pain was identified as a risk factor for unfavorable outcome. CONCLUSION In lateral cervical disc herniation, associated spondylosis or medial disc protrusion poses a significant risk of surgical failure and complications of dorsal foraminotomy. Reducing the radicular failure rate by enlarging the bony decompression may lead to local failure. In well-selected patients with a lateral cervical free disc fragment, dorsolateral foraminotomy is successful and safe.
