Summary
A 26-week-old female Boerboel was referred for evaluation of progressive left thoracic
limb lameness. Computed tomography and radiographic evaluation revealed radiolucency
of the caudal region of the proximal humeral metaphysis, absence of the humeral head,
and gross distortion of the glenoid. Given the severe glenohumeral deformation, arthrodesis
of the left shoulder was performed using orthogonal locking bone plates, lag screw
fixation, and bone grafting. Despite late implant failure, arthrodesis was successful
in this case, and satisfactory limb function was restored. To the author's knowledge,
this is the first report of a case of a focal developmental deficiency of the proximal
humerus reported in a dog.
