Osteochondrosis dissecans am Sakrum einer Berner Sennenhündin: Diagnostische und therapeutische Aspekte

Abstract

A 18-month-old female Bernese Mountain Dog with chronic pain at jumping, extension of the right hind leg and paresis of the tail was referred to the Neurological Service of the Veterinary Hospital of the University of Zurich. Upon radiological examination a mineralised fragment at the dorsal aspect of the endplate of S1 was detected. The diagnosis of Osteochondrosis dissecans was confirmed by linear and computed tomography as well as histologic examination of the fragment, which was surgically removed. Preoperative imaging allowed a minimal surgical approach using a unilateral, modified dorsal laminectomy. Outcome was evaluated by neurological reevaluation and a CT scan performed 6 months after surgery.

Magnetic Resonance Imaging Characterization of Vertebral Endplate Changes in the Dog

“…Consistent with prior publications,, , osteochondrosis was observed solely in the lumbosacral joint. Young male German Shepherds were overrepresented.…”

Clinically relevant osteochondrosis of the seventh lumbar vertebra in a Beagle

“…Lumbosacral OCD has been described in 68 German Shepherds, 4 Boxers, 3 Rottweilers, 2 Great Danes, 2 Springer spaniels, 2 Mastiff dogs, a Newfoundland dog and a Bernese mountain dog. (Lang et al, 1992;Snaps et al, 1998;Kriegleder, 2000;Hanna, 2001;Glyde et al, 2004;Michal et al, 2004;Mathis et al, 2009). To the authors' knowledge this is the first case reported in a Beagle.…”

“…Different medical imaging modalities have been described to establish a diagnosis of lumbosacral OCD and associated cauda equina compression (Lang et al, 1992;Snaps et al, 1998;Michal et al, 2004). Although survey radiographs are very helpful in reaching a diag nosis, the superposition of the iliac wings makes it difficult to detect smaller detached fragments (Lang et al, 1992;Kriegleder, 2000).…”

“…Although survey radiographs are very helpful in reaching a diag nosis, the superposition of the iliac wings makes it difficult to detect smaller detached fragments (Lang et al, 1992;Kriegleder, 2000). Although CT has been used for dogs with lumbosacral osteochondrosis (Michal et al, 2004;Mathis et al, 2009), there is little known about the CT features of this disease. The CT findings in the dog of the present case were very helpful to fur ther characterize the abnormality and to visualize the severe reduction of the dorsoventral vertebral canal diameter and cauda equina compression.…”
