Abstract

Incomplete ossification of the humeral condyle is a cause of forelimb lameness in dogs. Affected dogs are predisposed to humeral condylar fractures. Incomplete ossification of the humeral condyle has been reported in breeds such as Spaniel, Rottweiler, Labrador and Pug. Diagnosis is made by a radiographic or computed tomographic study of the elbow, while treatment includes the placement of a bone screw across the humeral condyle. This paper discusses the computed tomography findings of incomplete ossification of the humeral condyle in three Pinschers.

Highlights

Humeral condyle fractures from severe traumatic events are very common in dogs (Marcellin-Little et al 1994; Rovesti et al 1998)
The predisposing factor seems to be a bone disorder known as incomplete ossification of the humeral condyle (IOHC), which affects some dog breeds, such as Spaniel, Labrador, Rottweiler and Pug (Moores and Moores 2017)
In dogs affected by IOHC, the cartilaginous layer that separates the lateral and medial portion of the humeral condyle does not undergo complete ossification; an area of fibrous tissue that separates the two portions of the condyle remains (Carrera et al 2008)
