In a series of 14 dogs, fractures of both tibiae were caused by a "bone-breaker" designed in the authors' department and observed to produce a consistent and realistic canine fracture. One tibia was plated with a carbon fiber reinforced plastic (CFRP) plate and the other with a dynamic compression (DC) plate. Roentgenographic examination demonstrated healing of the CFRP-plated tibiae with abundant callus, and almost total remodeling of the fracture callus between ten and 20 weeks. Biomechanical testing by three-point bending revealed little difference between the strength of union of the fractures at 12-16 weeks. At 20 weeks, although the numbers were too small for statistical confirmation, the CFRP-plated tibiae were consistently stronger than the DC-plated tibiae.
在一组14只犬中，双侧胫骨骨折由作者所在科室设计的“骨破坏器”造成，观察发现该装置能产生一致且逼真的犬类骨折。一侧胫骨用碳纤维增强塑料（CFRP）板固定，另一侧用动力加压（DC）板固定。X线检查显示，用CFRP板固定的胫骨有大量骨痂形成且骨折愈合，在10至20周之间骨折骨痂几乎完全重塑。三点弯曲生物力学测试显示，12至16周时骨折愈合强度之间差异不大。在20周时，尽管样本数量太少无法进行统计学验证，但用CFRP板固定的胫骨始终比用DC板固定的胫骨更强。
