[Laser Doppler flowmetry in vital bone transplantation. Experimental and clinical results]

Laser Doppler Flowmetry allows the measurement of the blood flow rate of different types of tissue. Rib on a muscle pedicle was compared with rib on a vascular pedicle in an animal experiment. The morphological results were compared with the LDF-results. During eleven clinical transfers of iliac crest bone grafts and one osteocutaneous scapular flap the blood flow values were measured intraoperatively before and after the transplantation. Postoperative monitoring was possible for 48 hours with the endoscopic probe and a screw implant. The blood flow of vascularized bone transplants is excellent and even rises post-operatively in some cases.
