The injection of radio-opaque substances into veins was first introduced by Dos Santos in I938 to investigate acute thrombo-phlebitis, but the suggestion to inject contrast media into bones for venograms was due to the pioneer work of Ducing et al. (I95I), who demonstrated the physiology of circulation in bone. Intra-osseous venography, in spite of being shown by Begg in I954 and Dodd and Cockett in I956 to be safe and practicable, has not yet found general acceptance amongst surgeons and radiologists on account of imaginary difficulties and dangers. Using the intra-osseous technique, we report our experience of 50 consecutive venograms and we hope to show that the procedure is a satisfactory one.
