OBJECT In this paper the authors' goal was to identify histological and immunohistochemical differences between cervical disc hemrniation and spondylosis. METHODS A total of 500 cervical intervertebral discs were excised from 364 patients: 198 patients with disc herniation and 166 patients with spondylosis. We examined en bloc samples of(More)
OBJECTIVE To investigate the histopathological and immunohistochemical properties of degenerative changes in the ligamentum flavum of the cervical spine with calcium crystal deposition. METHODS Sections of the calcified ligamentum flavum harvested from 26 patients who required cervical decompression were examined by scanning electron microscopy (SEM),(More)
INTRODUCTION Spondyloptosis is the most severe of translation spine injuries. It results in complete disruption of the structural elements of the vertebral column and the adjacent paravertebral soft tissues, culminating in severe biomechanical instability. Although several cases of lumbosacral spondyloptosis have been documented, not many cases of traumatic(More)
Dumb-bell tumours often require extended resection of osseous structures of the spine and subsequent anterior and/or posterior stabilization. Minimally addressed microsurgical intraneural extracapsular resection of a neurinoma originating from around the neuroforamen often provides immediate benefits. We describe our experience with microsurgical(More)
