Objective : Ultrasonography (US) is the most non-invasive, safe, and, especially in the period of infancy, best method for visualizing and examining the spinal cord. Furthermore, US is the primary work-up for development of the spinal canal, and for follow-up on issues relating to subcutaneous tissues, bone development, and the spinal cord. Conus medullaris terminates at the second lumbar vertebra, according to a consensus in the literature. Methods : Healthy children under the age of 6 months who were admitted to the radiology clinic for routine USG follow-ups between the dates of March 2012 to December 2014 were included in this study. Results : Our study includes data from 1125 lumbosacral ultrasounds. The terminal point of the conus level of the attended infants, superior, middle part, inferior of the vertebrae L1, L2, and L3. Furthermore, the termination of the discal distance ratio did not differ significantly between genders. Conclusion : Therefore, according to our results, gender is not an influencing factor in the termination of the spinal cord. Based on the study we performed, as well as the previous literature, in infants without a recognized spinal pathology, the spinal cord is detected below the vertebra L3.

Study Design: Observational study. Purpose: To assess the correlational accuracy between the traditional anatomic landmarks of the neck and their corresponding vertebral levels in Southern Chinese patients. Overview of Literature: Recent studies have demonstrated discrepancies between traditional anatomic landmarks of the neck and their corresponding cervical vertebra. Methods: The center of the body of the hyoid bone, the upper limit of the lamina of the thyroid cartilage, and the lower limit of the cricoid cartilage were selected as representative surface landmarks for this investigation. The corresponding vertebral levels in 78 patients were assessed using computed tomography. Results: In both male and female patients, almost none of the anatomical landmarks demonstrated greater than 50% correlation with any vertebral level. The most commonly corresponding vertebra of the hyoid bone, the lamina of the thyroid cartilage, and the cricoid cartilage were the C4 (47.5%), C5 (35.9%), and C7 (42.3%), respectively, which were all different from the classic descriptions in textbooks. The vertebral levels corresponding with the thyroid and cricoid cartilage were significantly different between genders. Conclusions: The surface landmarks of the neck were not accurate enough to be used as the sole determinant of vertebral levels or incision sites. Intra-operative fluoroscopy is necessary to accurately locate each of the cervical vertebral levels.

Background: A spinal extension and intensive rehabilitation program reduced the symptoms and pain of kyphosis, and improved function. Objects: This study aimed to demonstrate the effect of a spine extension device on the degree of thoracic kyphosis and extension angles, confirm reduction of the kyphosis angle and an increase in flexibility. Methods: Thirteen adults were enrolled in the experiment, using the spine extension device, which was set to passively extend the spine. The angle between the spinous process of the first thoracic vertebra and the spinous process of the twelfth thoracic vertebra was measured by dual inclinometer before and after using the spine extension device. Results: In the static posture, the thoracic kyphosis decreased after using the spine extension device in the thoracic extension posture, and there was a significant difference (p < 0.05); thoracic extension angle increased with statistical significance (p < 0.05). Conclusion: In this study, the thoracic kyphosis angle and thoracic extension angle of the subjects before and after using spine extension device was compared and analyzed, which proved that the spine extension device can effectively improve the mobility of spinal extension.

In clinical orthodontics, it is significant to understand the stage of growth in a growing patient. In order to assess the skeletal maturity of the patients, the hand-wrist radiograph and the cervical vertebrae (Cervical Vertebrae Maturation Indicators : CVMI) was evaluated from the lateral cephalograph and the skeletal maturity determined from the hand-wrist X-ray (Skeletal Maurity Indicators : SMI) taken on the same day in the same patients, and its interrelationship examined to come up with the following results: 1. The skeletal maturity evaluated from the hand-wrist radiograph and the maturation of the cervical vertebrae from the lateral cephalograph showed a significant interrelationship with each other. 2. In the evaluation of the skeletal maturity using the SMI and CVMI, the CVMI 1 showed a siginificant correlation with SMI 1, 2, the CVMI 2 with SMI 3, 4, CVMI 3 with SMI 6, 7, CVMI 4 with SMI 7, 8, CVMI 5 with 9, 10 and CVMI 6 with SMI 11. 3. When the morphological changes in the 2nd and 3rd cervical vertebrae were separately observed, it was seldom that the concavity appeared in the lower border of the 2nd cervical vertebra and at the same time not appear in the 3rd cervical vertebra (CVMI 2 : 10.38%, CVMI 3 : 6.56%) 4. In each of the skeletal maturation stage evaluated from the hand-wrist and the cervical vertebra, the average age and its standard deviation in male and female patients appeared to have large differences among individuals. Skeletal maturation seemed to appear earlier for the girls than for the boys, and its termination 24 months faster for girls.

Objective : This study aimed to investigate the efficacy of transverse process (TP) hook system at the upper instrumented vertebra (UIV) for preventing screw pullout in adult spinal deformity surgery using the pedicle Hounsfield unit (HU) stratification based on K-means clustering. Methods : We retrospectively reviewed 74 patients who underwent deformity correction surgery between 2011 and 2020 and were followed up for >12 months. Pre- and post-operative data were used to determine the incidence of screw pullout, UIV TP hook implementation, vertebral body HU, pedicle HU, and patient outcomes. Data was then statistically analyzed for assessment of efficacy and risk prediction using stratified HU at UIV level alongside the effect of the TP hook system. Results : The screw pullout rate was 36.4% (27/74). Perioperative radiographic parameters were not significantly different between the pullout and non-pullout groups. The vertebral body HU and pedicle HU were significantly lower in the pullout group. K-means clustering stratified the vertebral body HU ≥205.3, <137.2, and pedicle HU ≥243.43, <156.03. The pullout rate significantly decreases in patients receiving the hook system when the pedicle HU was from ≥156.03 to < 243.43 (p<0.05), but the difference was not statistically significant in the vertebra HU stratified groups and when pedicle HU was ≥243.43 or <156.03. The postoperative clinical outcomes improved significantly with the implementation of the hook system. Conclusion : The UIV hook provides better clinical outcomes and can be considered a preventative strategy for screw-pullout in the certain pedicle HU range.

Retrophayngeal hematomas frequently develop in patients who had cervical vertebra fracture. The hematoma develops in the space between buccopharyngeal fascia and prevertebral fascia. But it rarely causes severe airway obstruction. We recently treated a patient who had dyspnea and dysphagia due to a retropharyngeal hematoma without any significant trauma history. First, tracheostomy was performed to maintain the airway. Then, incision and drainage was done under suspension laryngoscope. This case shows the fact that a retropharyngeal hematoma can result in severe airway obstruction even after a minor trauma.
