background: spine of an adult is made up of five areas that include 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, sacrum and finally coccyx. selecting appropriate assumptions for modeling and biological analysis of the spine components has a significant impact on the accuracy of results in biomechanical simulation for different modes. methods: in the present study, biomechani...

Introduction Severe osteoarthritis of the hip may cause abnormal spinopelvic alignment. Therefore, spinal alignment may change after total hip arthroplasty (THA); however, there have been no prospective clinical reports on the influence of preoperative lumbar lateral flexibility on the improvement of spinal alignment. The purpose of this study was to examine the effect of preoperative lumbar la...

Background & Objective:  Hyper- kyphosis negatively affects health status, physical mobility, and quality of life. Corrective exercise interventions are often utilized to manage subjects with thoracic hyper-hypnosis. The purpose of this study was to investigate the effectiveness of multimodal spine strengthening exercises (spinal strengthening, spinal alignment and other such exercises for incr...

Objectives Spinal sagittal alignment has been reported that it is highly associated with health related QOL in adult spinal deformity patients. Optimal sagittal alignment is critical for the efficient function of the musculoskeletal system. In Japan as aging country, a number of elderly people with spinal deformity seems to be increasing. In general, sagittal alignment of elderly people is more...

Background: Adult degenerative disorders of hip and spine are common. The recent studies inconsistently havediscussed about the influence of spinal disorders on total hip arthroplasty (THA). In this review, we discussed clearlyabout these relationships and their effects on the most appropriate position of the acetabular component.Methods: We searched on databases and evaluated the articles abou...

vertebral anomalies may also distort the normal regional or global spinal alignment and necessitate some therapeutic interventions. hemiepiphysiodesis is a traditional procedure usually described for these young patients but in more severe cases some type of osteotomy seems to be necessary. in this technical note, we describe a 5-year-old boy with failed previous hemiepiphysiodesis surgery, who...

Background: The back extensor muscles are the main spinal supportive factors which function establishes spinal stability and erect posture of the spine. Spine deviation from the ideal alignment, like abnormal increase in the forward curvature of the thoracic spine may cause changes in the trunk muscle activity which can lead to a change in the spinal proprioception. It seems that the corrected ...

BACKGROUND Abnormal posture and spinal mobility have been demonstrated to cause functional impairment in the quality of life, especially in the postmenopausal osteoporotic population. Most of the literature studies focus on either thoracic kyphosis or lumbar lordosis, but not on the change of the entire spinal alignment. Very few articles reported the spinal alignment of Chinese people. The pur...
