Case Reports
Implant failure of Bryan cervical disc due to broken polyurethane sheath: a case report.
A case report. ⋯ This case demonstrates the unique incident of broken Bryan disc after 8 years of implantation. Follow-up imaging shortly after the procedure should be mandatory to monitor such potential complication.

STUDY DESIGN.: Prospective in vivo randomized study. OBJECTIVE.: To evaluate the safety and efficacy of a distraction-based magnetically controlled growing rod (MCGR) in a porcine model. SUMMARY OF BACKGROUND DATA.: A high number of complications related to frequent surgical rod lengthenings has been a generally accepted outcome in growing rod surgery for early-onset scoliosis. ⋯ CONCLUSION.: The MCGR provided 80% of predicted spinal height by noninvasive remote distraction in this animal model. The accelerated increase in spinal height of the experimental animals after implant removal was an unexpected finding which requires additional research to better understand the effect of distraction on spinal growth. This study establishes a foundation for future research in an attempt to use a less invasive technique in distraction-based correction of early-onset scoliosis.

Experimental animal study of spinal cord injury (SCI), using a cell delivery system. ⋯ The combination of intrathecal transplantation of CD133 cells and application of a magnetic field at the site of injury is a possible therapeutic strategy to treat rat SCI and may therefore find application in clinical settings.
