Fractures of the tibia
Fractures of the tibia will usually cause a sudden, severe lameness, usually non-weight bearing, and have severe pain and swelling on palpation.
A suspected fracture is an emergency and a veterinary surgeon should be called before attempts are made to move the animal. A large bandage with a splint should be applied to support the limb.
Diagnosis
X-rays are required for diagnosis and to assess treatment options, although, in many instances examination of the animal can provide enough information as to whether the fracture is treatable or not.
Treatment
Complete fractures of a long bone in the horse generally carry a poor prognosis in adult horses and euthanasia is often performed to prevent suffering. Horses can be placed on strict box rest with the leg immobilized (bandage with a splint) or placed in a sling in some cases where the fracture is not displaced. Due to likelihood of healing being very low and the numerous complications that can occur, euthanasia on humane grounds must be considered. There have been only 1 or 2 cases of the successful treatment of a tibial fracture in horses ever.
