Significant findings Hit-by-car three days ago and non-weightbearing on both hind legs Ð The hit-by-car is a traumatic incident, which is this case, appears to have caused damage to both hind legs. The nature of the damage is unclear at this point and could be due to damage to the nerves, muscles, or bones. Clinical signs no worse than immediately after he was hit Ð This indicates that the injury is not progressive. Reflex responses in hind leg difficult to evaluate Ð This could indicate that nerve damage is present. Left leg has diffuse swelling while right leg has swelling distal to the stifle Ð The swelling could be due to the inflammatory response to the injury. However, the diffuse swelling could also indicate osteomyelitis. Introduction of agents that can cause osteomyelitis could have occurred during the accident. Discontinuity of the midshaft of the right tibia Ð The discontinuity of the midshaft of the right tibia indicates the presence of a right tibial fracture. Continuity of upper left femur questionable due to motion of limb and presence of crepitation Ð The lack of continuity at the hip joint could indicate a fracture of the femur or pelvis or luxation of the coxofemoral joint.
