Summary
         
         
            Objectives: To determine the prevalence of incomplete ossification of the humeral condyle (IOHC)
            and other osseous abnormalities of the elbow in English Springer Spaniels with no
            history of lameness.
         
         
            Methods: Prospective observational study of English Springer Spaniels with no recent history
            of lameness. Computed tomography scans of both elbows were obtained from dogs older
            than six months of age which were anaesthetized or sedated for reasons unrelated to
            this study. Computed tomography scans were reviewed for the presence of IOHC and other
            abnormalities of the elbow. Radioulnar incongruity (RUI) measurements from normal
            elbows were compared to elbows with IOHC and elbows with medial coronoid process (MCP)
            abnormalities.
         
         
            Results: Computed tomography scans from 50 dogs (100 elbows) were reviewed. The prevalence
            of IOHC was 14% (8 elbows in 7 dogs). All condylar fissures were incomplete with a
            mean length of 2.6 mm. Fifty percent of the dogs (44% of elbows) had abnormalities
            of the medial coronoid process and 60% of the elbows had periarticular osteophytes.
            Group RUI meansurements for IOHC and MCP were not significantly different from normal
            elbows.
         
         
            Clinical significance: Small IOHC fissures, periarticular osteophytes and MCP abnormalities may be identified
            in English Springer Spaniels without forelimb lameness. Abnormalities of the MCP are
            more common than IOHC.
