OBJECTIVE Anterior cervical discectomy and fusion (ACDF) is often complicated by subsidence, pseudoarthrosis, kyphosis, and graft donor site morbidities. To decrease the occurrence of these complications, various types of cages have been developed. We designed this retrospective study to analyze and compare the efficacy and outcomes of ACDF using double cylindrical cages (DCC) (BK Medical, Seou...

Objective. The objective of this study was to investigate the effect of a holistic intraoral appliance (OA) on cervical spine alignment and subjective symptom severity. Design. An observational study on case series with holistic OA therapy. Setting. An outpatient clinic for holistic temporomandibular joint (TMJ) therapy under the supervision of the Pain Center, CHA Biomedical center, CHA Univer...

OBJECTIVE the aim of the study was to compare the clinical effect of Zero-profile interbody fusion device (Zero-P) with anterior cervical plate interbody fusion system (PCB) in treating cervical spondylosis. METHODS a total of 98 patients with cervical spondylosis (110 segments) in February 2011 to January 2013 were included in our hospital. All participants were randomly divided into observa...

We derive new, sharp lower bounds for certain curvature functionals on the space of Riemannian metrics of a smooth compact 4manifold with a non-trivial Seiberg-Witten invariant. These allow one, for example, to exactly compute the infimum of the L2-norm of Ricci curvature for all complex surfaces of general type. We are also able to show that the standard metric on any complex hyperbolic 4manif...

Methods A 16-year-old male patient diagnosed with severe NMS with RSS underwent to a posterior spinal fusion from T5 to L1 at 10 years-old. Surgery reduced the Cobb’s angle at the main thoracic, lumbar and the cervical curvature to half. Nonetheless, post-surgery complications appeared: the cervical curvature increased, positive sagittal balance appeared, hyperextension of the neck and head, fl...

INTRODUCTION In musculoskeletal models of the cervical spine, the most common method for modeling muscles is straight paths from origin to insertion [1]. However, muscle paths in the neck are constrained by bone and other soft tissues, and some studies have found that applying curvature to muscle paths improves anatomical accuracy [2; 3] and affects muscle parameters such as moment arm [3] and ...

Jul 28, 2010. Can a cervical surgery and plates cause sleep apnea. Jan 16, 2014. Sleep apnea is common among spinal cord injury patients, a small new. Central sleep apnea, on the other hand, is rarer, and is caused by . Obstructive sleep apnea syndrome (OSAS) is a multi-factorial disease with many and hypopneas caused by repetitive collapse of the upper airway during sleep. deviations in patien...

BACKGROUND Cervical lordosis has been shown to be an important outcome of care; however, few conservative methods of rehabilitating sagittal cervical alignment have been reported. OBJECTIVE To study whether a seated, retracted, extended, and compressed position would cause tension in the anterior cervical ligament, anterior disk, and muscle structures, and thereby restore cervical lordosis or...
