Magnetic resonance imaging: findings of osteochondrosis like-lesions in glenoid fossa and proximal humeral metaphyses in a dog: a case report

Abstract

ABSTRACT:Osteochondritis dissecans (OCD) of the humeral head is a common cause of forelimb lameness in dogs. OCD represents the late phase of osteochondrosis (OC). Magnetic resonance imaging (MRI) is a useful technique for detection and characterisation of this disease. The main objective of this study was to show MRI findings of OCD in the humeral head, OC like-lesions in glenoid fossa and proximal humeral metaphyses of a dog. MRI analysis revealed the extent and severity of the inflammatory changes within the subchondral bones in both the glenoid cavity and humeral head. OCD and OC like-lesions were also evaluated in histopathological studies.

Use of Synthetic Osteochondral Implants to Treat Bilateral Shoulder Osteochondritis Dissecans in a Dog

“…2 The heritability of canine osteochondritis has not yet been established, but it is likely that there are genetic risk factors and environmental influences including diet and exercise. 1 Although glenoid osteochondritis has been reported, 3,4 canine shoulder osteochondritis almost exclusively affects the caudal part of the humeral head. The location of humeral head osteochondritis lesions has been defined on the basis of the lesion's relationship to the caudal margin of the glenoid allowing differentiation into type 1 (caudocentral) and type 2 (caudomedial) lesions.…”
