STUDY DESIGN A biomechanical study using a cadaver model was conducted to define the function of the nuchal ligament in the restraint of flexion of the cervical spine. OBJECTIVE To test the hypothesis that surgical resection of the nuchal ligament significantly reduces the structural restraints to cervical flexion. SUMMARY OF BACKGROUND DATA Although previous studies have examined the role ...

Cervical sagittal balance plays a pivotal role in spine surgeries as it has significant impact on the clinical outcomes cervical surgery. Image processing techniques have significantly improved accuracy and precision of surgical techniques. This study aims to investigate effects T1 slope (T1s) disappearance lordosis after posterior double-door laminoplasty using medical informatics radiographic...

BACKGROUND CONTEXT Surgery is usually required for treatment of cervical myelopathy to decompress the neural elements, restore lordosis, and stabilize the spine. By addressing these problems, the neurological deterioration may be halted. PURPOSE Multilevel cervical discectomy and fusion offers several advantages over other approaches. The authors describe the technique, discuss the indication...

Objective: Cervical spondylotic myelopathy is a progressive debilitating disease that favorably responds to surgical decompression. The objective of this study was to review the use of expandable titanium cages for reconstruction of the spine after cervical corpectomy. Methods: We searched PubMed and Google Scholar databases up to March 2013 to identify English articles reporting the use of exp...

STUDY DESIGN Technique description and retrospective data analysis. PURPOSE To describe the technique of cervical kyphosis correction with partial facetectomies and evaluate the outcome of single-stage posterior decompression and kyphosis correction in multilevel cervical myelopathy. OVERVIEW OF LITERATURE Kyphosis correction in multilevel cervical myelopathy involves anterior and posterior...

Intracerebroventricular (ICV) infusions of the selective mu receptor agonist morphiceptin produce a dual effect on lordosis behavior in ovariectomized, steroid-primed rats. Low doses of morphiceptin (20 ng) inhibit lordosis whereas higher doses (2000 ng) facilitate this behavior. The present experiment tested whether naloxone, an antagonist of both high- and low-affinity mu receptors, or the lo...

BACKGROUND To date, no study had reported the phenomenon of deteriorated postoperative cervical tilt in Lenke type 2 adolescent idiopathic scoliosis patients. The purpose of this study is to evaluate the cervical tilt in Lenke type 2 adolescent idiopathic scoliosis patients with right-elevated shoulder treated by either full fusion or partial/non fusion of the proximal thoracic curve. METHODS...

STUDY DESIGN An experimental approach was used to test human cadaveric cervical spine specimens. OBJECTIVE To assess the response of the cervical spine to a compressive follower load applied along a path that approximates the tangent to the curve of the cervical spine. SUMMARY OF BACKGROUND DATA The compressive load on the human cervical spine is estimated to range from 120 to 1200 N during...

OBJECTIVE Cervical spine encompasses a bridge role between the head and the lower parts of the spine and therefore has unique properties. Our aim in this study was to evaluate the cervical sagittal alignment parameters in pediatric and adult non-surgical patients and to find any differences in respect of age, sex and admission type. METHODS All patients who were admitted to emergency and neur...
