摘　　要：目的探讨兔胫骨内血流分布与骨内压的关系。方法将15只新西兰纯种大白兔制作成右胫骨上端骨内高压模型，模型制作前后测量患、健肢骨内压，采用红外热像图技术和同位素扫描方法分别检测患膝及健膝温度及放射浓集情况，比较其差异。结果患膝热像图呈现以膝关节为中心的温度升高图，患膝前、后侧温度为（25．06±0．67）、（25．17±0．36）℃，较健膝的（23．89±1．67）、（24．65±1．03）℃增高，差异有统计学意义（P〈0．05）。患膝放射性浓集度为（13．68±2．89）较健膝的（12．07±1．86）高，差异有统计学意义（P〈0．05）。结论骨内血流分布与骨内压呈正相关，红外热像图技术可用于测量骨内血流分布。Objective To evaluate the relationship between blood flow in the bone and bone inter- al pressure. Methods Fifteen New Zealand white rabbits were made into the tibia bone hypertension mod- el. The intraosseous pressure was measured before and after modeling. The infrared hot chart image forma- tion technology and the isotope scanning method were used to examine the lesioned knee and the healthy knee image formation temperature and the radioactivity enrichment situation separately, and the differences were compared. Results The thermal imagery chart of the lesioned knee showed the knee joint as the cen- tral temperature increment chart. The temperature in the lesioned knee was （25.06 ± 0. 67 ） and （25.17± 0. 36） ℃, and radioactivity enrichment was （13.68 ±2. 89）, which were significantly higher than the healthy knee [ （23.89 ± 1.67）, （24. 65 ± 1.03 ） ℃, and （ 12. 07 ± 1.86 ） ] （ P 〈 0.05 ）. Conclusion There was a positive relationship between the intraosseous pressure and distribution of blood flow. The in- frared thermography imaging could be used to measure the distribution of intraosseous blood flow.
