ABSTRACT
A prospective clinical study was designed to determine the effect of surgical approach on femoral stem position in canine cemented total hip replacement. Candidates for total hip replacement were randomly placed into one of two groups. In one group (n = 10), a craniolateral approach to the hip joint was made, incorporating a femoral trochanteric osteotomy. In the other group (n = 11), a craniolateral approach to the hip joint was made without performing a femoral trochanteric osteotomy. Radiographs obtained immediately after the operation were evaluated by two independent examiners for femoral stem position (neutral, varus, or valgus) and percentage of femoral canal fill, using a defined protocol. There was no statistical difference in femoral stem position between the study groups, whereas a greater percentage of canal fill was associated with the neutral femoral stem position.

Mycobacterium fortuitum was isolated from the lung of a dog that had new periosteal bone formation consistent with hypertrophic osteopathy. Fever, weight loss, and bilateral hind limb lameness were the initial clinical signs. The tarsi were swollen and a pain response was elicited on palpation of the hind limb. Radiography revealed periosteal new bone formation on the metatarsi, femurs, and ischii. Thoracic radiography revealed pulmonary mass lesions in the right middle and left caudal lung lobes. After right middle and left caudal lung lobectomy, M fortuitum was isolated from the excised tissues. Amoxicillin trihydrate/clavulanic acid and amikacin were administered, on the basis of susceptibility test results.
