Degenerative disc disease (DDD) is a common disabling condition for millions of individuals. Injection of xenogenic juvenile chondrocytes (XJC) into the disc space has been shown to have a therapeutic potential for disc repair. In the current study, XJC were injected extra-discally on neural structures in an in vivo rat hemilaminectomy model to compare the histological and behavioral effects on XJC and fibrin glue carrier. ⋯ While these results need to be confirmed over a larger period of time, they suggest that XJC transplantation into the disc space shows no adverse effect on nerve tissue.

In vivo evaluation of scoliosis treatment using a novel approach in which two posterior implants are implanted: XSLAT (eXtendable implant correcting Scoliosis in LAT bending) and XSTOR (eXtendable implant correcting Scoliosis in TORsion). The highly flexible and extendable implants use only small, but continuous lateral forces (XSLAT) and torques (XSTOR), thereby allowing growth and preventing fusion. ⋯ The approach accomplished the intended spinal deformation while allowing growth and preventing fusion.
