Hypothesis:  1  fracture of the left femur. tibia, and pelvis

The dog has a history of blunt trauma resulting sudden onset of hind limb lameness.   The orthapedic exam revealed incongruity in the right tibial bone and a swollen and painful left leg.   The exam showed an incontinuity in the tibia in the midshaft area   The exam did not reveal the exact origin of the left leg swelling and lameness.  The exam showed abnormal movements in the left hip area and occasional crepitice both consistent with fracture of the pelvis or femur.   Abnormal movement, swelling and crepatice are all consistent with multiple fractures due to the dog being hit by a car.   The dog was healthy before the incident.


Radiographs should be the next course of action.  The radiographs should reveal a fracture in the midshaft of the right tibia and fractures in the femur and/or pelvis.
