Bone cuts on the tibia of 6 healthy dogs were studied using surgical burs and microsaws arranged in two groups by random selection to assess the speed of cutting, precision and bone healing. Bone cuts in Group A were made with surgical burs of 1.6 mm diameter using micromotor at 40,000 revolutions per minute (RPM) whereas in Group B they were created using Stryker microsaws of 0.75 mm width at the speed of 40,000 RPM. In each group, the dogs were sacrificed at the end of 8, 12 and 16 weeks and a section of the tibia containing the fracture site was removed to assess healing histopathologically. Based on clinical, radiological and histopathological examination, the results of this study indicate that microsaws have their best use in osteotomy procedures in terms of precision and thermal injury to bone whereas ostectomy procedures are more convenient with surgical burs.
对6只健康犬的胫骨进行截骨研究，通过随机选择将使用外科磨钻和微型锯分为两组，以评估切割速度、精度和骨愈合情况。A组使用直径1.6毫米的外科磨钻，以每分钟40,000转（RPM）的速度通过微型电机进行胫骨截骨，而B组则使用宽度为0.75毫米的史赛克微型锯，以40,000 RPM的速度进行截骨。每组在8周、12周和16周结束时处死犬只，取出包含骨折部位的一段胫骨，进行组织病理学检查以评估愈合情况。基于临床、放射学和组织病理学检查，本研究结果表明，就精度和对骨的热损伤而言，微型锯在截骨手术中使用效果最佳，而骨切除术使用外科磨钻则更为方便。
