We investigated the histological and immunohistochemical features of degenerative changes in the ligamentum flavum of the lumbar spine with calcium crystal deposition. We investigated degenerative changes in 270 ligamentum flavum specimens harvested from 198 patients who underwent decompressive surgeries for lumbar spinal canal stenosis. En bloc sections of(More)
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)
Using a nonlinear three-dimensional finite element analysis simulating loading conditions, we designed a new type of proximal-fitting, anterolaterally-flared, arc-deposit hydroxyapatite-coated anatomical femoral stem (FMS-anatomic stem; Japan Medical Materials, Osaka, Japan) for cementless total hip arthroplasty (THA) for Japanese patients with dysplastic(More)
Onchocerciasis affects 7% of Uganda's population and 1.5 million more people are at risk of infection with Onchocerca volvulus, the nematode that causes the disease. This paper reports the results of part of a multi-centre study whose objective was to determine the prevalence of onchocercal skin disease and its associated psychosocial importance in Uganda.(More)
BACKGROUND Molecular biological techniques such as the polymerase chain reaction (PCR) and DNA microarray are used for the detection/identification of microorganisms; however, few reports have discussed the clinical utility of microarray analysis for identification of causative organisms of osteoarticular infections. It is important to examine the utility(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)
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)
A 58-year-old woman with an insignificant stage of diabetes mellitus presented with rapidly progressive osteoarthritis of her right knee exhibiting painless but significant antero-posterior and lateral instability. In association, she had a huge extruded left-sided cervical intervertebral disc at the C4-5 level. Neurological examination of the upper limbs(More)
