A report of successful combined endovascular and surgical management of an unusual case of metameric (juvenile) spinal arteriovenous malformation (AVM) is presented. The malformation had extradural and paraspinal components, but no intradural element

The authors present a novel technique of atlantoaxial fixation using multiaxial C-1 posterior arch screws. The technique involves the insertion of bilateral multiaxial C-1 posterior arch screws, which are connected by crosslinked rods to bilateral mu

A cervical intervertebral disc can prolapse (hernia or rupture) asymptomatically or may produce neck pain, nerve root compression (radiculopathy) or spinal cord compression (myelopathy). Surgery is indicated in cases of cervical myelopathy. In cases

The early clinical results with the Bryan Cervical Disc prosthesis are encouraging but 2 recent small published series have noted postoperative radiologic kyphosis of the functional spinal unit (FSU) of 4 and 6 degrees. The current study was undertak

STUDY DESIGN A biomechanical study using human spine specimens. OBJECTIVE The aim of this study was to assess whether the presence of cervical sagittal imbalance is an independent risk factor for increasing the mechanical burden on discs adjacent to
