Familial cases of "idiopathic" scoliosis associated with neurologic abnormalities are reported with a review of the literature. ⋯ It is suggested that familial neurologic abnormalities may have a wide range of expression, and that some patients with "idiopathic" scoliosis present with genetically determined craniovertebral malformations such as syringomyelia, Chiari 1 malformation, and tonsillar ectopia.

Retrospective review of charts and fluoroscopic, radiographic, and computed tomography images for 252 screws (41 patients). ⋯ Cervicothoracic, thoracic, and thoracolumbar spine injuries can be managed safely and effectively with thoracic pedicle screws inserted under multiplanar fluoroscopic imaging.

Nerve root blood flow was intraoperatively measured before and after discectomy for lumbar disc herniation and compared with clinical features. ⋯ The results of the current study suggest that immediate relief from pain and resolution of neurologic deficits soon after surgery are the result of early recovery from nerve root ischemia after discectomy, and that ischemia caused by mechanical nerve root compression is mainly related to the mechanisms underlying sciatic pain production and neurologic deficits.
