Objectives:

Elbow osteoarthritis (OA) is a common condition in dogs, often secondary to canine elbow dysplasia (CED), and leads to the development of osteophytes within the joint. Anconeal process osteophyte fractures have not been previously described in the veterinary literature, despite recognition of osteophyte fractures in human medicine. This study evaluates the clinical features, computed tomography (CT) findings, and treatment outcomes in dogs presenting with anconeal process osteophyte fractures.

Methods:

This retrospective case series reviewed the medical records of ten dogs diagnosed with anconeal osteophyte fractures at two referral centers. Inclusion criteria required a diagnosis confirmed via CT. Information was collected on breed, sex, age, history, clinical signs, imaging findings, and outcomes. Follow-up was obtained through consultations or phone calls.

Results:

The ten dogs presented with acute to subacute elbow lameness and were managed conservatively. All patients improved following treatment, with none requiring surgery. The mean age was 7.5 years, and the median weight was 28.2 kg. Seven dogs were Labrador Retrievers, and three were Staffordshire Bull Terriers. CT scans identified fractures in the anconeal osteophytes, ranging from fissures to complete fragments. No significant differences were found regarding sex or breed distribution.

Conclusions:

Anconeal osteophyte fractures, though previously undocumented, can be diagnosed with CT and successfully managed conservatively. Recognition of this condition allows for prompt and effective treatment of acute elbow lameness in dogs, minimizing the need for surgical intervention.
