[Complications caused by the plastic material used in a 2-stage flexor tendon grafting operation].

After the use of the silicone-rod method for the two-stage flexor tendon grafting without complications in more than 120 cases, there were found -- although an identical technique was used -- some cases of inflammatory reaction compelling the earlier removal of the rods and leading to poorer results. Tests showed that there are silicone-rubber rods on the market which differ widely in their physical qualities and, therefore, also show differences in their compatibility with tissue.
