Multicenter Study Comparative Study
Correction of moderate (<70 degrees) Lenke 1A and 2A curve patterns: comparison of hybrid and all-pedicle screw systems at 2-year follow-up.
Multiple reports have demonstrated the superiority of all-pedicle screw constructs, over hybrid and hook constructs, for severe sagittal and coronal deformities (>70 degrees) and have made anterior spinal releasing unnecessary for almost all spinal deformities. However, for lesser deformities, specifically coronal deformities <70 degrees, published studies have not been able to consistently demonstrate clinical superiority of all-pedicle screw constructs over hook or hybrid constructs. ⋯ All-pedicle screw systems had better coronal correction, lower instrumented vertebrae tilt, MT scoliometer measurements and scoliosis appearance questionnaire total measures than hybrid constructs. The improved coronal correction in the PS group is likely due, in part, to the higher number of spine fixation points than used in the hybrid groups.

Widening of the prevertebral soft tissues is one of several significant indirect signs of cervical spine trauma. This paper provides pediatric radiographic reference measurements for prevertebral soft tissues at C2 and C6, and for the ratio of soft tissue to vertebral width at C6. ⋯ We present prevertebral soft tissue measurements from a larger sample of subjects than published previously, which allows our values to be used with more confidence as a tool in screening for cervical spine injury.

The cause of adolescent idiopathic scoliosis (AIS) is unknown and is currently believed to be multifactorial. AIS is a largely asymptomatic condition and many adolescents with AIS are involved with organized athletics and physical activity. To date, no data exist indicating predictors of return to physical activity after posterior spinal fusion for AIS. In this cohort study, adolescents who underwent posterior spinal fusion for AIS were evaluated to determine what clinical, surgical, and demographic variables predicted rate of return play in organized athletics. ⋯ Prognostic Level II: retrospective Study.
