(18)F-FDG microPET imaging differentiates between septic and aseptic wound healing after orthopedic implant placement: a longitudinal study of an implant osteomyelitis in the rabbit tibia.

abstract：BACKGROUND AND PURPOSES:The nervous system plays an important role in bone metabolism. However, the effect of denervation on bone formation during distraction osteogenesis (DO) remains unclear. We studied neural influence on bone regeneration during DO in a rabbit model.
