The objective of this study was to discuss the variables influencing alignment mechanisms of the spine, with particular consideration of post-surgical alignment in adolescent idiopathic scoliosis. The analysis is based on information currently available in the literature, and on the authors' own experience, which includes surgical material from over 2200 cases of idiopathic scoliosis. Over...

Pathologies of spine like trauma, infection, malignancy or congenital problems can cause disturbed structural integrity causing deformity and displacement spine. This causes compression damage on spinal cord roots, which the is supposed to protect. In such situations, needs be decompressed, realigned fused in that position, so further injury prevented. Spinal fusion a natural process healing bo...

Materials and methods: Thirty three patients without cervical spine problems were enrolled in the study. Patients were randomized into direct laryngoscopy and Airtraq® groups. Assessment of movement of the cervical spine was made by taking 3 lateral cervical spine X-rays. First, when the cervical spine was in the neutral position, second during the greatest excursion of the cervical spine, and ...

We propose a per-frame upper body pose estimation method for sports players captured in low-resolution team sports videos. Using the head-center-aligned upper body region appearance in each frame from the head tracker, our framework estimates (1) 2D spine pose, composed of the head center and the pelvis center locations, and (2) the orientation of the upper body in each frame. Our framework is ...

BACKGROUND A proper sleep system can affect the spine support in neutral position. Most of the previous studies in scientific literature have focused on the effects of customary mattresses on the spinal alignment. To keep the spine in optimal alignment, one can use sleep surfaces with different zonal elasticity, the so called custom-made arrangements. The required stiffness of a sleep surface f...

STUDY DESIGN A prospective comparative study. OBJECTIVE This study aimed to establish cervical spine morphometry, alignment, and range of motion (ROM) and to clarify the impact of these age-related and degenerative changes. SUMMARY OF BACKGROUND DATA There are no studies that have evaluated differences in the results of cervical spine radiographs between a large series of cervical spondylot...

PURPOSE Laminectomy is generally the treatment of choice for removal of spinal tumors. However, it has been shown that laminectomy may cause instability due to damage of posterior elements of the spinal column, which may induce subsequent kyphosis in the future. Therefore, to reduce the risk of deformity and spinal instability after laminectomy, hemilaminectomy has been used. However, the mediu...

Assessment of the cervical spine using x-ray radiography is an important task when providing emergency room care to trauma patients. In clinical practice, a physician will inspect the alignment of the cervical spine vertebrae by mentally tracing three alignment curves along the anterior and posterior sides of the cervical vertebral bodies, as well as one along the spinolaminar junction. In this...

BACKGROUND The sagittal alignment of the spine changes depending on body posture and degenerative changes. This study aimed to observe changes in sagittal alignment of the lumbar spine with different positions (standing, supine, and various sitting postures) and to verify the effect of aging on lumbar sagittal alignment. METHODS Whole-spine lateral radiographs were obtained for young voluntee...
