Anterior cervical spine surgery is an established surgical intervention for cervical degenerative disease and high success rate with excellent long-term outcomes have been reported. However, indications of surgical procedures for certain conditions are still controversial and severe complications to cause neurological dysfunction or deaths may occur. This review is focused mainly on five widely performed procedures by anterior approach for cervical degenerative disease; anterior cervical discectomy, anterior cervical discectomy and fusion, anterior cervical corpectomy and fusion, anterior cervical foraminotomy, and arthroplasty. Indications, procedures, outcomes, and complications of these surgeries are discussed. 相似文献

前路融合术是目前治疗颈椎病的常规术式,但颈椎前路融合术后邻近节段的退变加速越来越受到人们的重视。融合术还引起脊柱的生物力学改变,且存在植骨和内固定器械的并发症及供骨区慢性疼痛等。此外,颈椎前路手术的主要目标是解除脊髓的压迫而不是融合,这些都是困扰脊柱外科医师的难题。人工颈椎间盘置换术可在进行脊髓减压并提供稳定的同时保持手术节段颈椎的活动度,为颈椎病的外科治疗开辟了新的途径。本文结合最新文献对该技术的发展和前景进行综述。 相似文献

BACKGROUND: Anterior cervical corpectomy and fusion with instrumentation is a common procedure for the surgical treatment of cervical spinal cord and/or nerve root decompression or for deformity correction. However, various postoperative complications have been associated with such a surgical intervention. Postoperative spondylolisthesis after an anterior cervical corpectomy with instrumentation is a serious complication that has rarely been addressed in the literature, and may potentially be underreported. CASE DESCRIPTION: A 44-year-old woman with degenerative disk disease, loss of cervical lordosis, congenital cervical stenosis at C5-C6, and a left-sided herniated disk at C6-C7 underwent an anterior cervical corpectomy of C6 with fusion and anterior plate stabilization of C5-C7. Early postoperative evaluation noted complete resolution of the patient's symptoms. At 6 months after surgery, the patient complained of neck pain and intermittent headaches. Radiographic evaluation noted fusion of the corpectomy strut graft with retrolisthesis of C5 on C6 and early myelomalacia at C5-C6. A cervical laminectomy with posterior instrumentation from C5 to C7 was performed and the patient's symptoms resolved. CONCLUSIONS: Postoperatively, a high index of suspicion should be present for the development of spondylolisthesis in patients undergoing an anterior cervical corpectomy and fusion procedure with or without instrumentation, particularly in individuals with persistent or new symptoms even after a "successful" operative procedure. The spine surgeon should address appropriate operative techniques and postoperative management to decrease the risk of spondylolisthesis after such a procedure. 相似文献

Historically, anterior cervical discectomy and fusion (ACDF) has been the preferred surgical technique to address myelopathy and radiculopathy due to cervical spine intervertebral disc disease. Continued design improvements and theoretical biomechanical advantages to cervical disc arthroplasty over the last decade have made cervical disc arthroplasty an appealing alternative to ACDF, especially in younger patient populations without significant spondylosis who may wish to preserve neck motion. This narrative review will discuss the recent advances in cervical disc arthroplasty in regard to material composition, overall design and resultant degrees of freedom of the devices, the potential sparing of neck range of motion, and the theoretical biomechanical advantages of an arthroplasty compared to an ACDF. 相似文献

Cervical spondylotic myelopathy is a disease of the cervical spine causing spinal cord compression secondary to spondylosis or ossification of the posterior longitudinal ligament. Anterior surgical options include anterior cervical discectomy and fusion, cervical corpectomy, and cervical disc arthroplasty. The surgeon must choose the right surgical option to decompress the cord, restore cervical lordosis, and adequately stabilize the spine. Although these surgical procedures are considered to be highly successful, each one is associated with complications. One must exercise great care when performing anterior cervical surgery and discuss with each patient the risks and benefits of the procedures. 相似文献

The surgical management of multi-level cervical spondylotic myelopathy (CSM) continues to garner debate within the spine community with regards to optimal management. Options include anterior and posterior decompression, with several options available to the surgeon in either approach. The objective of this article is to review the indications, surgical technique, and outcomes of laminectomy with fusion and instrumentation in the management of multi-level CSM. 相似文献

In the past 50 years tremendous advances have been made in the treatment of cervical disc disease with cervical fusion. Fusion rates have surpassed 95% after application of anterior cervical implants. Adjacent-segment degeneration, however, has plagued the long-term clinical success of cervical fusion. Cervical arthroplasty has been introduced to maintain cervical motion and potentially avoid or minimize adjacent-segment degeneration. If cervical arthroplasty is successful, the long-term results of surgery for cervical disc disease may improve; however, there are associated drawbacks that must be overcome. Implant wear, fatigue, and failure have been reported in cases of large-joint arthroplasty, and research is underway to limit these problems in cervical arthroplasty. In this article the authors trace the evolution of cervical fusion and the new technique of cervical arthroplasty. The nomenclature of cervical arthroplasty will also be introduced. 相似文献

Cervical disc arthroplasty has been developed as an alternative to anterior cervical discectomy and fusion with the advantages of preserving intervertebral motion, eliminating the risk of pseudarthrosis, and theoretically reducing adjacent segment degeneration. Several large prospective randomized trials have been conducted to investigate the clinical and radiographic results of cervical disc arthroplasty versus anterior cervical discectomy and fusion. Long-term results from these studies, however, show no difference in functional outcomes and no evidence to date in reduction of adjacent segment disease with arthroplasty. Although cervical disc arthroplasty is a safe and equivalent alternative, its superiority is yet unknown. 相似文献

The authors performed a systematic review and meta-analysis to evaluate whether there is a beneficial clinical effect of total disk replacement compared with anterior cervical diskectomy and fusion for the treatment of single-level symptomatic cervical disk disease. A comprehensive literature search of multiple databases, including PubMed (1966-2011), Cochrane Controlled Trials Register (CENTRAL; issue 1, 2011), and Embase (1984-2011), was conducted to identify studies that met the inclusion criteria. Methodologic quality was assessed and relevant data were retrieved, and if appropriate, meta-analysis was performed. Eight randomized controlled trials were identified; six of the 8 reported 24-month follow-up results. At 24 months, total disk replacement was demonstrated to be more beneficial for patients compared with anterior cervical diskectomy and fusion for the following outcomes: overall success rate (odds ratio [OR], 1.79; 95% confidence interval [CI], 1.37-2.33; P<.0001), overall reoperation rate (OR,.36; CI, .21-.61; P=0), reoperation rate for revision (OR, .12; CI, .02 to .64; P=.01), and visual analog scale neck pain scores (standard mean differences [SMD], -.48; CI, -.91 to -.05; P=.03). Other outcomes, including Neck Disability Index scores (SMD, -.02; CI, -.44 to .27; P=.67) and visual analog scale arm pain scores (SMD, -.21; CI, -.63 to .22; P=.34), demonstrated no differences between the 2 groups. For patients with single-level symptomatic cervical disk disease, total disk replacement was found to be more effective than anterior cervical diskectomy and fusion in the 2 outcomes of overall success rate and overall reoperation rate at 24 months. Long-term results also showed total disk replacement trended to be more effective than anterior cervical diskectomy and fusion in some aspects. 相似文献

Background
As the current standard treatment for symptomatic cervical disc disease, anterior cervical decompression and fusion may result in progressive degeneration or disease of the adjacent segments. Cervical disc arthroplasty was theoretically designed to be an ideal substitute for fusion by preserving motion at the operative level and delaying adjacent level degeneration. However, it remains unclear whether arthroplasty achieves that aim.Questions/purposes
We investigated whether cervical disc arthroplasty was associated with (1) better function (neck disability index, pain assessment, SF-36 mental and physical health surveys, neurologic status) than fusion, (2) a lower incidence of reoperation and major complications, and (3) a lower risk of subsequent adjacent segment degeneration.Methods
We conducted a comprehensive search in MEDLINE®, EMBASE, and Cochrane Central Register of Controlled Trials and identified 503 papers. Of these, we identified 13 reports from 10 randomized controlled trials involving 2227 patients. We performed a meta-analysis of functional scores, rates of reoperation, and major complications. The strength of evidence was evaluated by using GRADE profiler software. Of the 10 trials, six trials including five prospective multicenter FDA-regulated studies were sponsored by industry. The mean followups of the 10 trials ranged from 1 to 5 years.Results
Compared with anterior cervical decompression and fusion, cervical disc arthroplasty had better mean neck disability indexes (95% CI, −0.25 to −0.02), neurologic status (risk ratio [RR], 1.04; 95% CI, 1.00–1.08), with a reduced incidence of reoperation related to the index surgery (RR, 0.42; 95% CI, 0.22–0.79), and major surgical complications (RR, 0.45; 95% CI, 0.27–0.75) at a mean of 1 to 3 years. However, the operation rate at adjacent levels after two procedures was similar (95% CI, 0.31–1.27). The three studies with longer mean followups of 4 to 5 years also showed similar superiority of all four parameters of cervical disc arthroplasty compared with fusion.Conclusions
For treating symptomatic cervical disc disease, cervical disc arthroplasty appears to provide better function, a lower incidence of reoperation related to index surgery at 1 to 5 years, and lower major complication rates compared with fusion. However, cervical disc arthroplasty did not reduce the reoperation rate attributable to adjacent segment degeneration than fusion. Further, it is unclear whether these differences in subsequent surgery including arthroplasty revisions will persist beyond 5 years. 相似文献11.
Anterior cervical diskectomy and fusion provide satisfactory results in most instances of cervical disk herniation and cervical spondylosis. A variety of interpositioned grafts have been described for such problems at one or two levels. Multiple level anterior decompression and fusion for patients with spondylotic myelopathy produce satisfactory results in most instances and are particularly effective when a degenerative kyphosis is present. Appropriate patient selection and attention to technical aspects of exposure, neural decompression, and graft procurement and placement directly influence the surgical outcome. 相似文献

The optimal surgical treatment for multilevel cervical degenerative disc disease is still controversial. The purpose of this article is to review the current evidence of the hybrid cervical surgery, which combines anterior cervical discectomy and fusion and cervical disc arthroplasty, for treating this condition. This fusion-nonfusion hybrid procedure provides favorable biomechanics and promising clinical and radiographic outcomes in both contiguous and skip-level pathologies. However, further high-quality and long-term follow-up studies are required to provide strong evidence and validate the results of the hybrid cervical spine surgery. 相似文献

Background
Patients with cervical radicular syndrome due to disc herniation refractory to conservative treatment are offered surgical treatment. Anterior cervical discectomy is the standard procedure, often in combination with interbody fusion. Accelerated adjacent disc degeneration is a known entity on the long term. Recently, cervical disc prostheses are developed to maintain motion and possibly reduce the incidence of adjacent disc degeneration. A comparative cost-effectiveness study focused on adjacent segment degeneration and functional outcome has not been performed yet. We present the design of the NECK trial, a randomised study on cost-effectiveness of anterior cervical discectomy with or without interbody fusion and arthroplasty in patients with cervical disc herniation. 相似文献17.
Spinal arthroplasty is an acceptable alternative to fusion in many cases of disabling degenerative disc disease. Although arthroplasty has been demonstrated to be a safe and efficacious surgical option, complications related to the approach or the device may occur in few cases. Revision strategies for failed total disc arthroplasty can be planned as a posterior fusion, leaving the total disc replacement device in place, or by way of anterior removal with subsequent anterior fusion or revision replacement of the prosthesis. 相似文献

Cervical disc replacement is an innovative technology that preserves motion at the instrumented level and has evolved as a potential alternative to spinal fusion for the treatment of cervical radiculopathy and myelopathy. Despite the excellent results of anterior cervical discectomy and fusion, arthroplasty allows for motion preservation which may be beneficial. Although the initial and midterm results from the randomized clinical trials demonstrated safety and equivalent clinical success as compared to anterior cervical fusion; the evidence establishing the superiority of arthroplasty over fusion in terms of preventing adjacent segment degeneration/disease is not available at this time. 相似文献

Cervical kinematics after fusion and bryan disc arthroplasty 总被引:3,自引:0,他引:3
INTRODUCTION: Disc arthroplasty has been shown to provide short-term clinical results that are comparable with those attained with traditional anterior cervical discectomy and fusion. One proposed benefit of arthroplasty is the ability to prevent or delay adjacent level operations by retaining motion at the target level and eliminating abnormal adjacent activity. This paper compares motion parameters for single-level anterior cervical discectomy and fusion and disc replacement patients at the index level and adjacent segments. METHODS: Radiographic data from patients enrolled in a prospective, randomized clinical trial were selected for kinematic assessment of cervical motion. All patients received either a single-level fusion with allograft and anterior cervical plate (Atlantis anterior cervical plate, n=13) or a single-level artificial cervical disc (Bryan Cervical Disc prosthesis, n=9) at either C5/C6 or C6/C7. Flexion, extension, and neutral lateral radiographs were obtained preoperatively, immediately postoperatively, and at regular intervals up to 24-month time points. Cervical vertebral bodies were tracked on the digital radiographs using quantitative motion analysis software (QMA, Medical Metrics) to calculate the functional spinal unit motion parameters including range of motion (ROM), translation, and center of rotation. If visible, the functional spinal unit parameters were obtained at the operative level, and also the level above and the level below. RESULTS: As expected, significantly (P<0.006 at 3, 6, 12, and 24 mo) more flexion/extension motion was retained in the disc replacement group than the plated group at the index level. The disc replacement group retained an average of 6.7 degrees at 24 months. In contrast, the average ROM in the fusion group was 2.0 degrees at the 3-month follow-up and gradually decreased to 0.6 degrees at 24 months. The flexion/extension ROM both above and below the operative level was not statistically different for the disc-replaced and fusion patients, however, mobility increased for both groups over time. The anterior/posterior translation that occurs with flexion/extension motion remained unchanged for the disc replacement group at the level above the target disc preoperatively and postoperatively. In contrast, the translation increased for the level above the fusion. At the 6-month follow-up, the increase in translation was significantly greater for patients that were fused (P<0.02) than for patients that received a disc replacement. This change was not significant at 12 months. DISCUSSION: Previous studies have shown the Bryan disc to maintain mobility at the level of the prosthesis. The long-term clinical benefit of maintenance of motion is postulated to be the ability to delay or avoid adjacent level operations. This study reveals that there is no difference in flexion/extension ROM at the level above and below either a fusion or Bryan arthroplasty. There is, however, an increase in anterior/posterior translation at the cephalad adjacent level in patients with arthrodesis while the Bryan arthroplasty retains normal translation for the same amount of flexion/extension at the adjacent level. CONCLUSION: The Bryan disc may delay adjacent level degeneration by preserving preoperative kinematics at adjacent levels. 相似文献
