Patients with developmental cervical spinal stenosis are in the minority among the various ethnic groups in China, which are predominantly yellow, and are on the rise, especially with the aging population. Spinal cord injuries without radiographic abnormalities (SCIWORA) resulting from only minor trauma are also increasing in number. This often stems from cervical hyperextension damage, most often seen during hard braking of a car, where the patient is caused by a transient backward extension of the head. SCIWORA refers to a syndrome in which the spine shows no signs of fracture or dislocation on radiographs or CT, but clinical symptoms of spinal cord injury. Due to anatomical and biomechanical differences in the spine, the incidence, pathogenesis and severity of SCIWORA vary among age groups. Yang Ting, Department of Orthopedics and Traumatology, Jiangsu Provincial Hospital of Traditional Chinese Medicine Currently, MRI is the undisputed best clinical tool for evaluating traumatic spinal cord injury and therefore a valuable tool for SCIWORA patients, as it can show not only the degree of spinal stenosis but also the internal condition of the spinal cord in detail. Its high contrast resolution, absence of bony artifacts, multidimensional imaging, and ability to provide and identify neurological and extra-neurological injuries are useful in the diagnosis of SCIWORA and in the evaluation of prognosis. Unfortunately, there are very few reports on the MRI imaging characteristics of SCIWORA patients. Masaaki Machino et al. from Chubu Rosai Hospital in Japan verified the relationship with symptom severity and surgical outcome by exploring the incidence of intramedullary high signal (increased signal intensity [ISI]) and prevertebral high signal (PVH) on MRI images in SCIWORA patients. A total of 100 consecutive SCIWORA patients who underwent expanded vertebroplasty between April 1997 and December 2008 were included in the study. There were 79 males and 21 females; the mean age was 55 years, (16C87 years). Patients with fractures or the presence of traumatic instability such as subluxation or subluxation were excluded from this study. All patients were examined in the acute phase with force-position x-ray and high-resolution MRI. The incidence of both intramedullary and anterior high signal ranges were measured on MRI sagittal T2 images with C3 vertebral body height (VH) as the standard, and the incidence of both was assessed. Neurological function was measured by the Japanese Orthopaedic Association (JOA) scoring system, and JOA recovery rate.
