A retrospective study investigated the sagittal alignment in adolescent idiopathic scoliosis (AIS). ⋯ Thoracic kyphosis depended mostly on the spinal deformity, whereas lumbar lordosis was influenced mainly by the pelvic configuration. The scoliotic curve type was not associated with a specific pattern of sagittal pelvic morphology and balance. The pelvic incidence found in this study was significantly higher than that reported in the literature for normal adolescents. The role of the pelvic incidence in the pathogenesis of adolescent idiopathic scoliosis needs to be explored in a longitudinal study involving patients with adolescent idiopathic scoliosis and normal adolescents.

A cross-sectional and epidemiologic study investigated low back pain. ⋯ The outcome measures concerning physical health in this study were found to be correlated significantly, consistent with the proposed low back pain-related model.

An anatomic study investigated the cervical dorsal rami and major cervical paravertebral muscles. ⋯ With the posterior approach to the cervical spine, a precise knowledge of the cervical dorsal rami anatomy and the innervating patterns of the paravertebral muscles is necessary for avoidance of inadvertent injuries to the nerves.

Ventilator weaning after staged revision anteroposterior spine fusion in a ventilator-dependent child with congenital scoliosis is reported. ⋯ Surgical correction of a severe thoracic spinal deformity in the setting of severe restrictive lung disease can be performed successfully with stabilization of pulmonary volumes and improvement in pulmonary performance.
