Accuracy of ultrasonography in detecting fragmentation of the medial coronoid process in dogs.
OBJECTIVE
To determine the accuracy of ultrasonography in detecting fragmentation of the medial coronoid process (FMCP) in dogs.


METHODS
Cross-sectional study.


METHODS
102 dogs (112 elbow joints) suspected to have FMCP.


METHODS
Elbows were examined ultrasonographically prior to surgery for evidence of fragmentation, fissuring, or deformation of the medial coronoid process; thickening of the joint capsule; joint effusion; and secondary new bone formation. Results were compared with intraoperative findings.


RESULTS
At surgery, 51 (46%) joints had free fragments, 55 (49%) had nondisplaced fragments, and 6 (5%) did not have any fragments or fissures. Fragments were not seen ultrasonographically in 23 of the 51 (45%) joints in which a free fragment was found during surgery or in 50 of the 55 (91%) joints in which a nondisplaced fragment was found during surgery. Accuracy of using ultrasonographic evidence of any medial coronoid process abnormality (ie, a medial coronoid process fragment, deformation of the medial coronoid process, or both) for diagnosis of medial coronoid process fragmentation was 77%. The kappa coefficient for the level of agreement between ultrasonographic (ie, any medial coronoid process abnormality) and surgical findings was -0.014, indicating that there was no agreement.


CONCLUSIONS
Results suggested that ultrasonography was of limited diagnostic value in detecting FMCP in dogs.
