While some limited discussion of the role of CO2 laser application in orthopaedic surgery has appeared in professional literature, a search of orthopaedic and podiatric journals has failed to uncover reports of the laser's effects on bone healing. This study examined osteotomies created with an oscillating saw and a CO2 laser in a rabbit model. The results showed that bone healing was comparable in both groups, but that healing was delayed in the laser group because inert-appearing bone fragments seemed to inhibit the healing process. Further study is indicated to determine the mechanism by which the CO2 laser delayed healing and whether lasers can enhance healing under certain conditions.
虽然专业文献中已有一些关于二氧化碳激光在骨科手术中应用的有限讨论，但检索骨科和足病学杂志未能发现有关激光对骨愈合影响的报道。本研究在兔模型中检查了用摆动锯和二氧化碳激光造成的截骨术。结果显示两组的骨愈合情况相当，但激光组的愈合延迟，因为看似无活性的骨碎片似乎抑制了愈合过程。需要进一步研究以确定二氧化碳激光延迟愈合的机制，以及激光在某些条件下是否能促进愈合。
