To date, there have been no reports of experiments designed to induce scoliosis by direct damage of different areas of the spinal cord. In a series of rabbits with medullary damage, the authors attempted selectively to interrupt the pathways that mediate proprioceptive input. Unilateral lesion of the dorsal column and posterior horn of the spinal cord was performed using three different techniq...

Posterior spinal instrumentation and fusion techniques are used over decades to correct spinal deformities higher than 40 degrees in scoliotic subjects [1]. Although these methods are successfully decreased the spinal curvature in scoliosis, the biomechanical loading of the distal unfused vertebrae is not well studied after operation. Among unfused vertebrae sacrum, the connective vertebra betw...

The objective of this study was to investigate short segment decompression of degenerative lumbar scoliosis (DLS) and the efficiency of fusion treatment.After DLS surgery, the patients were retrospectively reviewed using the VAS (visual analog scale) and ODI (Oswestry Disability Index) to assess clinical outcomes. All patients underwent posterior lumbar decompressive laminectomy, pedicle screw ...

Can J Surg, Vol. 45, No. 3, June 2002 219 A idiopathic scoliosis (AIS) involves a deformity of the spine that is commonly assessed by physicians. The external trunk deformity is also recognized as a major concern in AIS, especially for the patient. Therefore, many authors advocate that that consideration be given to simultaneous surgical correction of spinal and trunk deformities. During poster...

BACKGROUND The correction of trunk deformity is crucial in scoliosis surgery, especially for the patient's self-image. However, direct visualization of external scoliotic trunk deformity during surgical correction is difficult due to the covering draping sheets. METHODS An optoelectronic camera system with 10 passive markers is used to track the trunk geometry of 5 scoliotic patients during c...

Synaptic plasticity often involves changes in the structure and composition of dendritic spines. Vesicular cargos and organelles enter spines either by exocytosing in the dendrite shaft and diffusing into spines or through a kinesin to myosin hand-off at the base of spines. Here we present evidence for microtubule (MT)-based targeting of a specific motor/cargo pair directly into hippocampal den...

BACKGROUND AND PURPOSE Adult lumbar scoliosis is an increasingly recognized entity that may contribute to back pain. We investigated the epidemiology of lumbar scoliosis and the rate at which it is unreported on lumbar MR images. MATERIALS AND METHODS The coronal and sagittal sequences of lumbar spine MR imaging scans of 1299 adult patients, seeking care for low back pain, were reviewed to as...
