Specialty Exams:

Right Tibia and Fibula:  There is a closed, complete fracture of both the tibia and fibula.  They are closed because there were no external injuries noted on the physical exam.  The fractures are mid-shaft, unstable, and comminuted.  Unstable means that the bone fragments do not interlock.  They are comminuted because there are bone fragments, and the fracture lines can meet at a common point.

Left Femur:  The bone has a mid-shaft fracture that is closed and unstable.  It is comminuted and complete.

Clinical Pathology:  The alkaline phosphatase is elevated.  This can refer to either bone or liver damage.  The alanine aminotransferase, an indicator of hepatic damage, is normal.   Alkaline phosphatase can be elevated normally in a growing dog.  Because this is a large breed dog at 17 months old, his bones may not yet be fully mature.  Therefore, the elevation is probably due to the combination of the immature dog and the extensive damage to the bones.
	The glucose is elevated, most likely from stress.  The corticosteroids released in stress cause the liver to make increased amounts of glucose.  To further support this finding, we looked at the leukogram.  We would expect to find a stress leukogram with increased neutrophils and possibly monocytes.  We would also expect that a lymphopenia would be present.  The lab data only reported percentages, so we were unable to evaluate the true leukogram numbers.  
	The hematocrit of 22% is low.  This indicates that there is hemorrhage occuring.  The lab data does not indicate the red cell count or the platelet count, so we cannot determine if there is an existing anemia.  There is trace blood noted in the urine, but the red cell count in the urine is not significantly elevated.  
	The dog may be dehydrated due to the inflammation occuring at the sites of injury.  This is supported by the hyponatremia which means that the sodium could follow the fluid leaking from the vessels into the interstitium.
