BACKGROUND: Cervical total disc replacement was developed to preserve motion and reduce adjacent-level degeneration relative to fusion, yet concerns remain that total disc replacement will lead to altered facet joint loading and long-term facet joint arthrosis. This study is intended to evaluate changes in facet contact force, pressure and surface area at the treated and superior adjacent levels before and after discectomy, disc replacement, and fusion. METHODS: Ten fresh-frozen human cadaveric cervical spines were potted from C2 to C7 with pressure sensors placed into the facet joints of C3-C4 and C4-C5 via slits in the facet capsules...

PURPOSE OF REVIEW: Cervical disc replacement (CDR) has emerged as a motion-preserving alternative to anterior cervical discectomy and fusion in selected cases. Despite favorable literature, CDR is not universally accepted because of concerns regarding bias in the existing literature. The purpose of this review is to identify the possible biases in the disc replacement literature. RECENT FINDINGS: Recent studies that compare CDR and ACDF have demonstrated equivalent or superior outcomes, lower rates of secondary surgery, and equivalent safety at medium- and long-term follow-up...

REVIEW
I David Kaye, Alan S Hilibrand
PURPOSE OF REVIEW: The precise etiology of adjacent segment disease following cervical spine surgery is controversial. Theories for development include inevitable changes secondary to the natural progression of the degenerative cascade and changes secondary to altered biomechanics of the fused cervical spine. Motion preserving techniques, such as cervical disc arthroplasties (CDA), have been introduced with the hopes of reducing the rates of adjacent segment pathology. Recently, 7-year data from the investigational device exemption (IDE) studies have been published...

PURPOSE: The efficacy and safety of endoscopic posterior cervical foraminotomy (EPCF) have been demonstrated for single-level cervical radiculopathy, but no report in the medical literature has described the clinical results of two-level EPCF. The aim of this study was to assess the clinical and radiological outcomes of two-level EPCF performed in patients with cervical radiculopathy. METHODS: Twenty-two consecutive patients (9 females and 13 males) that underwent two-level EPCF with cervical radiculopathy from January 2012 to January 2014 were included in this study...

While abnormal loading is widely believed to cause cervical spine disc diseases, in-vivo cervical disc deformation during dynamic neck motion has not been well delineated. This study investigated the range of cervical disc deformation during an in-vivo functional flexion-extension of the neck. Ten asymptomatic human subjects were tested using a combined dual fluoroscopic imaging system and MRI based 3D modeling technique. Overall disc deformation was determined using the changes of the space geometry between upper and lower endplates of each intervertebral segment (C3/4, C4/5, C5/6 and C6/7)...

A 6-year-old girl presented to hospital with a 4 day history of increasing neck pain. White blood cell count was normal with slightly raised C-reactive protein. The patient had a limited range of neck movement, and experienced enhanced pain with neck extension. X-ray and cervical computed tomography (CT) confirmed the diagnosis of cervical intervertebral disc calcification (IDC) and IDC with ossification of the posterior longitudinal ligament (OPLL), respectively. The symptoms improved after approximately 1 week following rest and oral acetaminophen...

In contrast to other levels of upper disc spaces, the Luschka joints are usually absent at the C7/T1 disc space. Therefore, it has been reported that the C7/T1 disc herniation is prone to herniate laterally rather than centrally. In this manuscript, we describe an extremely rare central-type disc herniation at the C7/T1 level presented with myelopathy. A 76-year-old man presented with a 20-day history of progressive gait disturbance. Physical examination revealed bilateral lower extremity hyperreflexia and mild foot numbness with no upper extremity motor weakness or sensory disturbance...

The motions of individual intervertebral joints can affect spine motion, injury risk, deterioration, pain, treatment strategies, and clinical outcomes. Since standard kinematic methods do not provide precise time-course details about individual vertebrae and intervertebral motions, information that could be useful for scientific advancement and clinical assessment, we developed an iterative template matching algorithm to obtain this data from videofluoroscopy images. To assess the bias of our approach, vertebrae in an intact porcine spine were tracked and compared to the motions of high-contrast markers...

OBJECTIVE Cervical disc arthroplasty (CDA) has been demonstrated to be as safe and effective as anterior cervical discectomy and fusion (ACDF) in the management of 1- and 2-level degenerative disc disease (DDD). However, there has been a lack of data to address the fundamental discrepancy between the two surgeries (CDA vs ACDF), and preservation versus elimination of motion, in the management of cervical myelopathy associated with congenital cervical stenosis (CCS). Although younger patients tend to benefit more from motion preservation, it is uncertain if CCS caused by multilevel DDD can be treated safely with CDA...

BACKGROUND: Cervical radiculopathy is a common disorder that portends significant morbidity. The presence of radiculopathy can have a debilitating effect on patients as well as a significant economic impact. Active duty military patients with increased physical occupational demands can be significantly impacted by cervical disease. The resulting disability can have a strong negative impact on operational readiness. Several studies have demonstrated comparably good functional outcomes between cervical disc arthroplasty (CDA) and anterior cervical discectomy and fusion for single-level disease...

OBJECTIVE: To evaluate the clinical efficacy and safety following percutaneous disc decompression, using navigable disc decompression device for cervical herniated nucleus pulposus (HNP). METHODS: Twenty subjects diagnosed with cervical HNP and refractory to conservative management were enrolled for the study. The herniated discs were decompressed under fluoroscopic guidance, using radiofrequency ablation device with navigable wand. The sagittal and axial plain magnetic resonance images of the clinically significant herniated disc, decided the space between the herniated base and outline as the target area for ablation...

Cervical disc arthroplasty is a common method of treating cervical degenerative disease. However, the footprints of most prosthesis dimensions are obtained from data of Caucasian individuals. Besides, there is a large discrepancy between footprints of currently available cervical disc prostheses and anatomic dimensions of cervical endplates. We aimed to detail the three-dimensional (3D) anatomic morphology of the subaxial cervical vertebral endplate, utilizing high-precision, high-resolution scanning equipment, and provide a theoretical basis for designing appropriate disc prostheses for Chinese patients...

This report presents a case of a 52-year-old man who had a traffic accident and died later. External examination could not determine the cause of death. Approximately 3 weeks later, an autopsy was performed. Postmortem computed tomography was performed before the autopsy. Postmortem imaging was interpreted to show hemorrhage beneath the tentorium, and the C5 to C6 (the fifth and sixth cervical vertebra) disc space was widened. During the autopsy, a cervical spinal cord injury was confirmed. However, a meningioma was found under the tentorium instead of a hemorrhage...

BACKGROUND: Cervical spinal tuberculosis is relatively common in some developing countries. It erodes vertebrae and discs, which sometimes results in cervical kyphosis and myelopathy. However, to our knowledge, no studies have evaluated improvements to patient-reported outcomes among patients who undergo surgical cervical sagittal realignment after kyphotic cervical spinal tuberculosis has been treated by débridement and reconstruction. QUESTIONS/PURPOSES: (1) Can a spine with kyphotic cervical spinal tuberculosis be returned to normal alignment and fused successfully? (2) Will patient-reported outcomes be improved with this intervention? (3) Are patient-reported outcomes correlated with realignment? METHODS: Forty-six patients with kyphotic cervical spinal tuberculosis were evaluated in this retrospective study...

BACKGROUND: Several scoring systems for cervical disc and facet joint degeneration, using radiography or computed tomography, have been developed and tested for reliability. However, definitions of disc height and facet joint space narrowing vary. To our knowledge, no study has reported quantitative data for normal radiologic values of the cervical spine in the Korean population. The purpose of this study is to determine normal cervical disc height, disc height ratio, and facet joint space values, and investigate the correlation between demographic data and these values...
