摘要：

A preparation of an isolated bovine forefoot was established which could be perfused with blood al variable rates. A laser Doppler flowmeter probe inserted into the cancellous bone of the metatarsal produced a signal which varied with changes in perfusion rale and oscillated in synchrony with the peristaltic perfusion pump. A stronger laser Doppler signal was obtained when the probe was inserted into a drill hole than when inserted into a hole bored with a guide wire. It appears that laser Doppler flowmetry has potential intraoperative use when the viability of bone is in question. © 1990 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
