[Animal experimental scintigraphic studies of closed lower leg fractures during the 1st 24 hours following the fracture trauma].
A closed fracture in the medium third part of the tibia was carried out in 50 rabbits. The scintigraphy was performed in groups of 5 animals at a time 2, 4, 6, 10, 12, 14, 16, 18, and 24 hours after the fracture trauma, in each case 45 minutes after the injection of 8 MBq 99mTc diphosphonat per kg body weight. The ROI activity quotient of both shank diaphysis was analysed. The first ascent was observed at the tenth postoperative hour. The ROI activity quotient was 2.1 24 hours after the fracture trauma. No marking of the fracture area was observed but an increase of the activity altogether above the diaphysis, and no ascent of the activity quotient in the neighbouring joints was observed.
