SUCCESSFUL TREATMENT OF 2 CASES OF METAPHYSEAL OSTEOMYELITIS IN THE DOG

This paper describes two cases of metaphyseal osteomyelitis in young dogs. The condition was characterised by generalised stiffness, muscle atrophy and reluctance to stand. Pain was evident on deep palpation of the distal extremities of long bones. Radiographic lesions, consisting of diffuse areas of bone lysis and pronounced periosteal reaction, were demonstrated in the metaphyseal regions of multiple long bones, particularly the distal radii and ulnae. Growth plates appeared unaffected and remained open. Biochemical abnormalities included significant increases in the plasma concentrations of fibrinogen and alkaline phosphatase. A pronounced neutrophilia and absolute monocytosis were noted in one dog. A six week course of amoxycillin/clavulanic acid in combination with metronidazole resulted in complete resolution of clinical and radiographic signs in each case. Growth disturbances were not observed.
