The effect of environmental temperature on the rate of healing of fractures in tail vertebrae of mice

The effect of the environmental temperature on the healing of fractures was assessed in vertebrae of tails of young albino mice. It was found that fractures in animals kept at 33 degrees Celsius healed very rapidly (bony callus by 14 days) while in animals kept in the cold (8 degrees Celsius) fractures were still at the stage of granulation tissue at this time. Controls were at an intermediate stage. This result might have a clinical application.
