The epidemiology of spinal cord injury without radiographic abnormality (SCIWORA) is less frequently reported in adults as compared with children. The annual incidence of SCIWORA was approximately 5.74% per million in Tianjin from 2004 to 2008. Importantly, the epidemiological characteristics of adult SCIWORA may be different from that in children. The aim of this study was to evaluate the radiological-clinical data of patients with adult SCIWORA, and to relatively analyze the epidemiological features. ⋯ It is clear that adult cervical SCIWORA is different from that in the pediatric group. Our study highlights the epidemiological properties of adult SCIWORA in Tianjin, China. Differing from other reports, particularly epidemiology study, we represent the first report regarding adult SCIWORA from China. As the geriatric population increases, it is very important to set up an individualized evaluation system based on a nationally scaled epidemiological database. The results from our study will be useful in assisting in the creation of such a database.

This article aims to provide an overview of how spinal deformities can alter normal spine and thoracic cage growth. ⋯ Growth is a succession of acceleration and deceleration phases and a perfect knowledge of normal growth parameters is mandatory to understand the pathologic modifications induced on a growing spine by an early onset spinal deformity. The challenges associated with the growing spine for the surgeon include preservation of the thoracic spine, thoracic cage, and lung growth without reducing spinal motion.

Review Case Reports
Pedicle screw instrumentation in adolescent idiopathic scoliosis (AIS).
Pedicle screw instrumentation in AIS has advantages of rigid fixation, improved deformity correction and a shorter fusion, but needs an exacting technique. ⋯ Rod derotation and DVR using pedicle screw instrumentation give true three dimensional deformity correction in the treatment of AIS. Suk classification with these methods predicts exact fusion extent and is easy to understand and remember.

Multicenter Study
Effect of direct vertebral body derotation on the sagittal profile in adolescent idiopathic scoliosis.
We sought to clarify the effect of applying derotation maneuvers in the correction of adolescent idiopathic scoliosis (AIS) on the sagittal plane. ⋯ Although patients in both groups had decreased mean thoracic kyphosis postoperatively, application of DVBD in the correction of scoliosis did not additionally worsen the sagittal profile.
