PURPOSE: Current standard methods to quantify disc height, namely distortion compensated Roentgen analysis (DCRA), have been mostly utilized in the lumbar and cervical spine and have strict exclusion criteria. Specifically, discs adjacent to a vertebral fracture are excluded from measurement, thus limiting the use of DCRA in studies that include older populations with a high prevalence of vertebral fractures. Thus, we developed and tested a modified DCRA algorithm that does not depend on vertebral shape...

OBJECT: Total disc replacement (TDR) is typically indicated in young patients with a cervical soft disc herniation. To date, there are few data on the activity level of patients after cervical TDR; in particular, from young patients who are expected to have a high activity level with frequent exercising. The expectation is that returning to active sports after cervical TDR is not restricted. METHODS: Fifty patients were treated with a monosegmental cervical TDR at our department between May 2006 and March 2012...

BACKGROUND: This experimental study provides a qualitative description and the morpho-structural features of the fusions taking place in the thoracic spine between prepubertal age and skeletal maturity. There is a lack of informations regarding the influence of partial or total dorso-thoracic vertebral arthrodesis on the development of the thoracic cage as well as its potential effects on different intra and extra-thoracic organs. This study admits the hypothesis that vertebral arthrodesis may have influence on other body areas and so, it intends to verify the possible secondary involvement of other body parts, such as intervertebral discs, cervical and thoracic spinal ganglia, sternocostal cartilage, ovaries and lungs...

There is no study about cervical herniated intervertebral disc (cervical HIVD) in physicians in the literature; therefore, we conceived a retrospective nationwide, population-based cohort study to elucidate the topic. We identified 26,038 physicians, 33,057 non-physician healthcare providers (HCPs), and identical numbers of non-HCP references (i.e., general population). All cohorts matched a 1:1 ratio with age and gender, and each were chosen from the Taiwan National Health Insurance Research Database (NHIRD)...

BACKGROUND: Anterior cervical discectomy and fusion (ACDF) is a well-accepted treatment option for patients with cervical spine disease. Three- and four-level discectomies are known to be associated with a higher complication rate and lower fusion rate than single-level surgery. This study was performed to evaluate and compare zero-profile fixation and stand-alone PEEK cages for three- and four-level ACDF. METHODS: Two cohorts of patients who underwent ACDF for the treatment of three- and four-level disease were compared...

OBJECTIVE: Post-operation of cervical decompression fusion and internal fixation (CDF) accelerated adjacent segment disc degeneration (ASD). It is not clear that whether instability of one single segmental accelerates the degeneration of adjacent segment disc. This study aims to explore the effect of cervical instability on the change of morphology and biochemistry in adjective segment (above) in the L5/6 cervical instability rabbit models. METHODS: Thirty-two mature New Zealand white rabbits (3000±250g) were randomly divided into two groups, control group (n=8) and model group (n=24)...

PURPOSE: The generation and tissue origination of disc-associated axial pain is still under exploration. This study was performed to evaluate disc-associated axial pain and to explore whether it originates in the disc or its surrounding components. METHODS: A 6-year series of 88 single-level Smith-Robinson disc and posterior longitudinal ligament (PLL) resections performed to treat single-level cervical spondylotic myelopathy was retrospectively examined. All single-level anterior disc decompressions were performed under local infiltration anesthesia; the PLL was not anesthetized to avoid cervical cord block...

BACKGROUND CONTEXT: Cervical disc arthroplasty has been gradually adopted as an alternative for the treatment of cervical degenerative disease. However, there is a large discrepancy between footprints of currently available cervical disc prostheses and anatomic dimensions of cervical endplates. PURPOSE: To accurately and comprehensively quantify the three-dimensional (3D) anatomic morphology of the cervical vertebral endplate and provide a theoretical basis for designing appropriate disc prostheses...

PURPOSE: Patients with pre-existing cervical spinal canal stenosis (CSCS) may have minimal or no symptoms. However, performing preventive decompression is controversial as the incidence of CSCS leading to severe cord injury is unknown. Hence, this study aims to revisit the threshold for surgery in "silent" CSCS by reviewing the neurologic outcomes of patients with undiagnosed CSCS who sustained a cervical spinal cord injury (CSCI). METHODS: Two groups of subjects were recruited for analysis...

BACKGROUND: Adjacent segment degeneration frequently develops following anterior cervical discectomy and fusion. The objectives of the present study were to characterize the long-term evolution of degenerative radiographic changes at segments adjacent to anterior cervical fusion and to identify factors associated with the development of these changes, including the preoperative condition of the cervical spine and parameters related to arthrodeses. METHODS: One hundred and sixty-six patients who underwent anterior cervical discectomy and fusion for symptomatic cervical spondylosis or disc herniation were followed radiographically for a mean time of 12...

The study was performed to preoperatively assess the cartilage integrity of cervical intervertebral discs (IVDs) using Delayed Gadolinium-Enhanced Magnetic Resonance Imaging of Cartilage (dGEMRIC). Therefore, 53 cervical intervertebral discs of nine preoperative patients with neck and shoulder/arm pain scheduled for discectomy (five females, four males; mean age: 47.1 ± 8.4 years; range: 36-58 years) were included for biochemical analysis in this retrospective study. The patients underwent 3T magnetic resonance imaging (MRI) including biochemical imaging with dGEMRIC and morphological, sagittal T2 weighted (T2w) imaging...

OBJECTIVE: Cervical disc arthroplasty (CDA) has been designed as a substitute for anterior cervical discectomy and fusion (ACDF) in the treatment of symptomatic cervical disc disease (CDD). Several researchers have compared CDA with ACDF for the treatment of symptomatic CDD; however, the findings of these studies are inconclusive. Using recently published evidence, this meta-analysis was conducted to further verify the benefits and harms of using CDA for treatment of symptomatic CDD. METHODS: Relevant trials were identified by searching the PubMed, EMBASE, and Cochrane Library databases...

Fractures of the second cervical vertebra (C2, axis) are common in adult spine surgery. Those fractures occurring in younger adult patients are often associated with high-energy mechanism trauma, resulting in a "Hangman's Fracture." Management of these fractures is often successful with nonoperative means, though surgery may be needed in those fractures with greater displacement and injury to the C2-C3 disc. Older patients are more likely to sustain fractures of the odontoid process. The evidence supporting surgical management of these fractures is evolving, as there may be a mortality benefit to surgery...
