In a retrospective study, common neurologic signs and results of treatment of cervical vertebral instabilities were reviewed. In 16 large dogs, vertebrae C5 and C6 were most frequently malformed and unstable. Treatment was conservative in 3 dogs, 1 dog was not treated, and 12 dogs were treated surgically (dorsal decompressive laminectomy and wire stabilization of the articular facets in most cases). The 3 conservative treatments and 8 of the 12 surgical treatments were considered beneficial.
A 6.5-year-old, female Saint Bernard had a slowly growing tumor of the right tibiotarsal joint. Radiographically, bone surrounding the tumor was not involved. Subtotal surgical resection was undertaken. The tumor was classified histologically as a synovioma. Within 6 months, the tumor recurred locally and invaded the soft tissue proximal to the tibiotarsal joint. Eighteen months after initial examination, there was widespread right tibial invasion and pulmonary metastasis. The dog was euthanatized. The final histopathologic diagnosis was synovial sarcoma.
A 4-year-old male German Shepherd Dog sustained subluxation of the right radiocarpal joint. A coaptation splint did not adequately stabilize the carpus, and arthrodesis of the radiocarpal joint was undertaken, utilizing a wedge graft and bone plate. Despite successful fusion of the joint, lameness persisted in the affected limb. The lameness was attributed to subsequent carpometacarpal subluxation, which was presumed to result from the added stress of weight bearing on the carpometacarpal joint following the arthrodesis. Arthrodesis of the right intercarpal and carpometacarpal joints, utilizing cortical bone grafts and a bone plate, restored normal gait.
