Specialty Exams

	The lateral and dorsopalmar radiographs show a complete short oblique 
diaphyseal fracture of the left 
metacarpus III and IV. The fracture is misaligned and there is non-viable 
delayed union due to a defect in 
the bone that has left a gap at the fracture site. There is diffuse soft tissue 
swelling visible surrounding the lower 
limb.  There is also increased opacity in the mid to proximal diaphyseal region 
with some bony lysis and 
proliferation around the fracture site. The proliferation suggests callus 
formation, which is a normal finding 
in fracture healing, but the positive culture of E. coli and Staphylococcus 
aureus confirms osteomyelitis.  
The infection was probably inoculated through the open wounds on the calfŐs leg.  
There were no 
significant findings in the hematology, CBC, or urinalysis, indicating that the 
calf most likely does not have 
any systemic involvement from a disseminated infection.
