Role of trauma on acute haematogenic osteomyelitis aetiology.

In this study we attempted to assess the role of trauma in acute haematogenic osteomyelitis (AHO). Twenty-four 6-8 week-old white New Zealand rabbits were divided into three groups. Group 1 received an injury to the proximal tibias; group II received a standardized bacteraemia with Staphylococcus aureus; group III received both the trauma and the bacteraemia. Scintigraphy was done by Gallium-67 citrate and, histopathologic examination was used for the diagnosis of osteomyelitis. In contrast to group I, AHO was seen in one case in group II and in all cases of group III.
