SummaryAn 11 month old, female Golden Retriever was examined for chronic right thoracic limb lameness and progressive swelling of the distal radius. Survey radiographs revealed an expansile, osteolytic lesion in the distal metaphyseal region of the radius consistent with an aneurismal bone cyst. Diagnostic imaging, biopsy, angiography and histopathology supported this diagnosis. The condition was treated by segmental osteotomy of the affected radius, placement of a vascularized autogenous bone graft harvested from the contralateral ulna, and stabilized using a plate that incorporated the carpal joint. The pathogenesis, diagnostic dilemmas and treatment options in dogs and human patients is discussed.

Endoscopy was used to determine the prevalence of subclinical gastroduodenal ulceration in 30 Dachshunds undergoing decompressive surgery for acute intervertebral disc prolapse. The endoscopy was performed on the day of admission and on the 3rd or 4th day after surgery. Three regions of the stomach (cardia, corpus and pylorus) and the proximal duodenum were visually inspected and biopsy samples were taken for histopathology. The combination of visual and microscopic changes were then used to determine the prevalence of subclinical gastroduodenal ulceration in this population. An overall prevalence of 76 % was calculated from these findings. Ulcerogenic medication administered prior to admission did not appear to influence the prevalence. This result identifies a need for veterinarians to be aware of this potentially severe complication and warrants the use of prophylactic anti-ulcer medication in spinal surgery patients
