Constrictive myelopathy secondary to hypoplasia or aplasia of the thoracolumbar caudal articular processes in Pugs: 11 cases (1993–2009)

Abstract

In the present study, presence of aplastic or hypoplastic articular processes in the thoracolumbar region did not always produce neurologic signs. However, fibrous constrictive myelopathy should be considered in Pugs with pelvic limb gait and postural reaction deficits and lack of hyperpathia upon palpation of the vertebral column. Additional studies are warranted to further characterize the disease process and determine the most effective means of treatment.
