背景：膝关节手术中使用的截骨工具产生的热量可诱发热性骨坏死，可能导致植入物无菌性松动。本研究在温度生成和组织学损伤方面比较了摆锯和电锯。使用冲洗，以降低骨temperatures.Methods：温度记录在锯和钻孔冲洗或不冲洗（未冷却或冷却）。然后进行组织学分析。对两组之间的差异进行了统计学检验（α = 0.05）。结果：平均而言，去毛刺产生的温度高于锯切（P <0.001）。当使用非冷却冲洗时，锯骨的骨温度明显低于钻骨（P <0.001）。冲洗降低了温度和热损伤深度，增加了骨细胞活力（P <0.001）。结论：这些结果表明，在切除术中冲洗骨可以防止骨坏死的发生。(C)2016 Elsevier Inc.

Background: Heat from bone resecting tools used in knee surgery can induce thermal osteonecrosis, potentially causing aseptic implant loosening. This study compared oscillating saws to burrs in terms of temperature generation and histologic damage. Use of irrigation to reduce bone temperature was also investigated.Methods: Temperatures were recorded during sawing and burring with or without irrigation (uncooled or cooled). Histologic analyses were then carried out. Differences between groups were tested statistically (alpha = 0.05).Results: On average, burring produced higher temperatures than sawing (P < .001). When uncooled irrigation was used, bone temperatures were significantly lower in sawed bone than in burred bone (P < .001). Irrigation lowered temperatures and thermal damage depths and increased osteocyte viability (P < .001).Conclusion: These results suggest that irrigating bone during resection could prevent osteonecrosis onset.
