Spinal cord injury research triggering an immune system response. Animal studies with injection of bone marrow stem cells have shown improvement in motor function; however not so in a human trial a year post-injury. More trials are underway. Adipose and umbilical tissue stem cells need further study before human trials can be performed, but two Korean studies were begun to investigate adipose cells in SCI patients. Transplantation of tissues such as olfactory ensheathing cells from the olfactory bulbs has been shown to produce beneficial effects in spinal cord injured rats. Trials have also begun to show success when olfactory ensheathing cells are transplanted into
Spinal cord injury without radiographic abnormality for even better depiction of the spine and soft tissue abnormalities in particular. Again, a novel acronym was proposed to classify patients without traumatic signs using radiographs, CT and MRI. The term spinal cord injury without neuroimaging abnormality (SCIWONA) was used. However, the novel acronyms were not generally accepted and the more general term SCIWORA is usually used to describe all variants of clinico-radiological mismatches. Spinal cord injury without radiographic abnormality Spinal cord injury without radiographic abnormality (SCIWORA) is symptoms of a spinal cord injury (SCI) with no evidence of injury to the spinal column on X-rays or CT scan.
