A case report. ⋯ A hypermobile segment in the pediatric KFS patient is a risk factor that may lead to cord compression. A symptomatic herniated cervical disc may develop from an excessive mechanical load stress in a pediatric KFS patient with multiple fused segments. In such a patient, a same-day combined posterior-anterior procedure provides cord decompression and stabilizes the spine with a favorable outcome.

A retrospective radiographic analysis of 47 intact cadaver pediatric cervical spines at the Hamann-Todd Osteology Collection in Cleveland, Ohio. ⋯ Our results showed an overall increase in the pedicle axis and pedicle width but no significant change in pedicle length. The data in this study indicate that pedicle screws may not be safe for use in the pediatric cervical spine, particularly younger children. The use of lateral mass screws was not specifically addressed in this study. As in the thoracolumbar spine, growth of the pedicles in relation to the spinal canal is lateral to the canal. The vertebral body itself appears to contribute most to overall pedicle axis growth, while the pedicle itself contributes a progressively smaller percentage over time.

Randomized Controlled Trial Comparative Study
A randomized controlled trial investigating the efficiency of musculoskeletal physiotherapy on chronic low back disorder.
Randomized, single blind, controlled trial. ⋯ As a component of musculoskeletal physiotherapy, the spinal stabilization program is more effective than manually applied therapy or an education booklet in treating chronic low back disorder over time. Both manual therapy and the spinal stabilization program are significantly effective in pain reduction in comparison to an active control. To our knowledge and up until now, this result has not been shown in patients with chronic low back disorder.

Randomized Controlled Trial
A prospective randomized study of posterolateral lumbar fusion using osteogenic protein-1 (OP-1) versus local autograft with ceramic bone substitute: emphasis of surgical exploration and histologic assessment.
A prospective, randomized and controlled study. ⋯ In a human posterolateral lumbar spine trial, OP-1 reliably induced viable amounts of new bone formation, but the fusion success rate evaluated by surgical exploration was only 4 of 7.
