Abstract
Objectives
To estimate, using CT imaging, differences in the regional bone density of the humeral condyle in
Labrador Retriever elbows with and without medial coronoid process disease (MCPD).
Materials and Methods
The elbows of Labrador Retrievers that had undergone CT were reviewed. Scans were divided into
three groups; Group N - elbows without MCPD; Group R - elbows with MCPD involving
fragmentation of the radial incisure; Group A - elbows with MCPD involving fragmentation of the
medial coronoid apex. A templating technique was employed to define the weightbearing regions of
the medial and lateral portion of the humeral condyle, and estimates of volumetric bone density
(defined by Hounsfield unit measurement, HUM) were compared across the three groups.
Results
CT evaluation was performed on 122 elbows in 81 dogs. There was a higher mean HUM in the medial
and lateral portions of the humeral condyles in Group A compared with Group R.
Clinical Significance
Dogs with apical fragmentation of the medial coronoid process exhibited significantly higher
estimated bone mineral density within the medial portion of the humeral condyle when compared to
dogs with radial incisure fragmentation. The medial portion of the humeral condyle may be associated
with the pathogenesis of apical but not radial incisure medial coronoid process fragmentation in
Labrador Retrievers.
