The origin and nature of pseudo-synovium appearing around implanted Silastic rods: an experimental study

The pseudo-synovium appearing around Silastic rods is a labile layer made up of a range of cells from undifferentiated fibroblast precursors through to mature fibrocytes. Various factors influencing their behaviour are discussed. The optimum time for grafting into a rod-induced sheath would seem to be in excess of four months.
