“…The average sagittal spinal cord diameter was 7.72mm ± 0.75 mm at C3, 7.75mm ± 0.70 mm at C4, 7.56mm ± 0.59mm at C5, 7.12mm ± 0.65mm at C6 and 6.15mm ± 0.65mm at C7 vertebral level. This is similar to a study carried out by Sherman et al and Kar et al 12,13 The maximum SAC value was noted at the C7 vertebral level [5.78mm] and the minimum SAC was noted at C4 vertebral level. Tierney et al found that SAC ranged from 2.5 to 10.4 mm and was maximum at C7 and minimum at C3 and C5 in 71% of the subjects.…”

“…In a study performed on the North Bengal population by Kar et al using MRI, they reported the average sagittal canal diameter was 11.99mm±1.34mm in males and 12.15mm±1.24 mm in the females which is similar to our study. 13 In a study carried out in the eastern Nepalese population by Singh et al using plain radiograph, they measured the average sagittal canal diameter as 17.18mm±1.67mm which is slightly higher than in our study. 10 This may be because of variations in magnification and the distance from the X-ray source to the film as well as from the subject to the film as these can confound the measurements.…”

Introduction: Cervical spinal stenosis has been established as a predisposing factor of cervical myelopathy and is associated with cord injury. Space available for the cord (SAC) can be used as an indicator of spinal stenosis. Methods: This study was performed on patients referred for MRI examinations of the cervical spine for various clinical indications to a tertiary centre in Nepal. Data were collected for a period of four months from January to April after IRB approval. Convenience sampling was employed and a total of 72 examinations were included. Data were obtained from the 1.5T Magnetom Amira Siemens MRI scanner. Sagittal diameters of the spinal canal and spinal cord were traced and measured from C3 to the C7 vertebra. The space available for the spinal cord (SAC) was calculated by subtracting the sagittal cord diameter from the corresponding sagittal canal diameter. Results: The average space available for cord was 4.48mm±1.04mm at C3, 4.44mm±1.03mm at C4, 4.63mm±1.01mm at C5, 5.11mm±1.07mm at C6, 5.87mm±1.14mm at C7 vertebral level. The SAC value was not significant according to gender and age (p>0.05). Conclusions: The smallest SAC value was detected at the C4 vertebral level with a mean value of 4.44mm and the greatest value was at C7 vertebral level with a mean value of 5.87mm. There was no significant gender difference in SAC values.

“…Отмечается возможность про-слеживания процесса дегенерации и потери жидкости фиброзного кольца, пульпозного ядра и замыкательных пластин [4,5]. Зарубежные исследователи и практикующие хирурги также убеждены в высокой значимости и важности предоперационного обследования пациентов с применением МР-томографии, позволяющей определить патологические изменения в позво-ночном канале, степень выраженности ком-прессии спинного мозга и количество вовлечен-ных уровней [6,7,8].…”

ель исследования. Анализ роли современных методов лучевой диагностики, визуализации, контроля, а также их использования как в ходе предопераци-онной подготовки и оперативного лечения пациентов со стенозом позвоноч-ного канала шейного отдела позвоночника, так и в послеоперационном пери-оде.Материалы и методы. Проведено хирургическое лечение 25 пациентов со сте-нозом позвоночного канала шейного отдела позвоночника различной протяженности. Всем пациентам выполнялись рентгенологическое и МРТ-исследования на этапе доопе-рационного обследования, а также контрольные МРТ и КТ исследования в послеопера-ционном периоде. Оперативное лечение выполнялось из миниинвазивного переднебо-кового шейного парафарингеального доступа с установкой межтелового кейджа из ма-териала PEEK нулевого профиля с блокирующим механизмом, наполненного остеокон-дуктивной пастой на основе гидроксиапатита и β-трикальцийфосфата. На всех этапах оперативного пособия проводился рентгенологический контроль при помощи электрон-но-оптического преобразователя.Результаты. В результате тщательного предоперационного обследования, пла-нирования хирургического пособия и использования современных методов визуализа-ции в ходе оперативного вмешательства у 22 пациентов получен отличный ранний по-слеоперационный результат с выпиской на амбулаторное долечивание на 3-4 сутки по-сле оперативного лечения. У 3 пациентов в раннем послеоперационном периоде разви-лась симптоматика вторичного отека корешка, устраненная медикаментозным лечени-ем, пациенты выписаны из стационара на 9-10 сутки после операции. При последую-щих контрольных исследованиях через 6 и 12 месяцев у 17 (68,0%) из 25 пациентов на фоне отсутствия признаков дегенеративно-дистрофических изменений смежных уров-ней отмечались явления образования межтелового спондилодеза, дислокации имплан-тата зарегистрировано не было. Динамическое наблюдение за пациентами продолжено.Заключение. Применение современных методов лучевой диагностики на всех этапах (предоперационное обследование, планирование оперативного пособия, хирур-гическое вмешательство, наблюдение в послеоперационном периоде) лечения пациен-тов со стенозом позвоночного канала шейного отдела позвоночника позволяет получить отличные и хорошие результаты в абсолютном большинстве наблюдений и является за-логом успеха в лечении данной категории пациентов.Ключевые слова: стеноз позвоночного канала, шейный отдел позвоночника, ми-ниинвазивный спондилодез, дискэктомия, МРТ, КТ, спондилография.

“…However, there were some studies for symptomatic tandem spinal stenosis and in this study, we have focused spinal canal and body diameter without signi cant degeneration and its ratio with using the reformatted images of CT scans. Although the CT scan don't reveal disc degeneration or ligament hypertrophy associated with clinical symptoms, it can accurately measure spinal canal and vertebral body, compared to using the x-ray or MRI 20 . Secondly, all the cases of this study have visited our hospital regardless of the patients' diagnosis and had both cervical and lumbar CT scans.…”

A known prevalence of concurrent cervical and lumbar spinal stenosis was shown to be 5%-25%, but there is a lack of evidence regarding direct relationships in canal dimension and canal-body ratio between cervical and lumbar spine. Total 247 patients (mean age: 61 years, male: 135) with cervical and lumbar computed tomography scans were retrospectively reviewed. Midsagittal vertebral body and canal diameters in reconstructed images were measured at all cervical and lumbar vertebrae, and canal-body ratios were calculated. The canal diameter and ratio were also compared according to the gender and age, and correlation analysis was performed for each value. There were significant correlations between cervical (C3-C7) and lumbar (L1-L5) canal dimension (p < .001). C5 canal diameter was most significantly correlated with L4 canal diameter (r = .435, p < .001). Cervical canal-body ratios (C3-C7) were also correlated with those of lumbar spine (L1-L5) (p < .001). The canal-body ratio of C3 was most highly correlated with L3 (r = 0.477, p < .001). Meanwhile, mean canal-body ratios of C3 and L3 were significantly smaller in male patients than female (p = .038 and p < .001) and patient’s age was inversely correlated with C5 canal diameter (r=-.223, p < .001) and C3 canal-body ratio (r=-.224, p < .001). Spinal canal dimension and canal-body ratio have direct relationships between cervical and lumbar spine. Physicians can explain that if the cervical canal is narrow, the lumbar canal is also likely to be narrow.
