STUDY DESIGN: Narrative review. OBJECTIVES: Anterior cervical discectomy and fusion (ACDF) is a reliable procedure, commonly used for cervical degenerative disc disease. For interbody fusions, autograft was the gold standard for decades; however, limited availability and donor site morbidities have led to a constant search for new materials. Clinically, it has been shown that calcium phosphate ceramics, including hydroxyapatite (HA) and tricalcium phosphate (TCP), are effective as osteoconductive materials and bone grafts...

PURPOSE: It is difficult for clinicians to inform patients about the success rate of a treatment as a cervical anterior discectomy procedure. Ideally, a proportion of good outcome as rated by patients is known. Patient-reported outcome measurements are helpful. The purpose is to relate the difference in Neck Disability Index (NDI) after a cervical anterior discectomy procedure for single level cervical degenerative disc disease with the patients' rating of their actual clinical situation after long-term follow-up to define the substantial clinical benefit (SCB)...

BACKGROUND: Patients with cervical disc disease may present with radiculopathy (root compression), myelopathy (cord compression), or myeloradiculopathy. These complaints must be correlated with x-ray, magnetic resonance (MR) imaging, and computed tomographic (CT) scans. Although most patients can be managed nonsurgically, those with significant neurological deficits and larger disc herniations may require surgery. METHODS: The symptoms of cervical radiculopathy include pain radiating down one or both arms, while myelopathy may result in more diffuse numbness tingling or weakness in the upper and/or lower extremities...

Filamin B (FLNB) is a large dimeric actin-binding protein which crosslinks actin cytoskeleton filaments into a dynamic structure. Up to present, pathogenic mutations in FLNB are solely found to cause skeletal deformities, indicating the important role of FLNB in skeletal development. FLNB-related disorders are classified as spondylocarpotarsal synostosis (SCT), Larsen syndrome (LS), atelosteogenesis (AO), boomerang dysplasia (BD), and isolated congenital talipes equinovarus, presenting with scoliosis, short-limbed dwarfism, clubfoot, joint dislocation and other unique skeletal abnormalities...

BACKGROUND: Finite element models have been widely used to predict biomechanical parameters of the cervical spine. Previous studies investigated the influence of position of rotational centers of prostheses on cervical biomechanical parameters after 1-level total disc replacement. The purpose of this study was to explore the effects of axial position of rotational centers of prostheses on cervical biomechanics after 2-level total disc replacement. METHODS: A validated finite element model of C3-C7 segments and 2 prostheses, including the rotational center located at the superior endplate (SE) and inferior endplate (IE), was developed...

INTRODUCTION: Pain drawings have been frequently used in the preoperative evaluation of spine patients. For lumbar conditions comprehensive research has established both the reliability and predictive value, but for the cervical spine most of this knowledge is lacking. The aims of this study were to validate pain drawings for the cervical spine, and to investigate the predictive value for treatment outcome of four different evaluation methods. METHODS: We carried out a post hoc analysis of a randomized controlled trial, comparing cervical disc replacement to fusion for radiculopathy related to degenerative disc disease...

BACKGROUND CONTEXT: Although the cervical spine is only occasionally involved in rheumatoid arthritis (RA), involvement of the lumbar spine is even less common. A few reports on lumbar spinal stenosis in patients with RA have appeared. Although disc space narrowing occurs in aging, postoperative adjacent segment disease (ASD) in patients with RA has not been subject to much analysis. PURPOSE: The objective of this study was to investigate differences in ASD and clinical outcomes between lumbar spinal decompression with and without fusion in patients with RA...
