Soft-tissue blood flow following reamed versus unreamed locked intramedullary nailing: A fractured sheep tibia model

摘要: A study was performed to compare the effects of reamed versus unreamed locked intramedullary nailing on soft-tissue blood flow in a fractured sheep tibia model. After creation standardized short spiral fracture, each stabilized by insertion nail. Ten animals were randomized into two groups : one that had reaming prior nail and did not. Blood measured real time, using laser Doppler flowmetry. Skin muscle perfusion measurements made at three locations (proximal diaphysis, fracture site, distal diaphysis) five time intervals (postfracture ; postnail insertion; 2-week, 6-week, 12-week follow-ups). All sacrificed 12 weeks postoperatively. Muscle remained elevated longer group than group, following completion procedure. significantly greater (p < 0.033) skin 2 0.024). There no difference between any interval. The demonstrates is altered nailing. findings demonstrate change surrounding envelope during process revascularization, devascularization segment tibial cortex
