Immobilization times vary due to fracture configuration, age, and disposition of the animal. Young calves may heal a fracture within 3 weeks, whereas adult cattle with comminuted tibial fractures may require 10 weeks to heal. Radiographic evidence of fracture healing may not be evident at the time of splint removal. A guideline to follow is to remove the splint if the limb feels stable and there is evidence some callus is being formed radiographically. Some form of continued splintage of the limb may be considered to lend support as active mineralization takes place. Weight transfer to the limb seems to increase mineralization of the callus, and within two weeks of removal, radiographic mineralization will be readily apparent. Activity after removal should be restricted for four to six weeks. Further time may be needed to completely rehabilitate the leg.
