Radiological changes associated with traumatic posterior paralysis and spinal fixation in dogs

Eighteen dogs with traumatic posterior paralysis presented to the College Hospital were treated by spinal fixation with or without hemilaminectomy or non-surgically (Groups A, B and C respectively of six dogs each). They were subjected to radiological evaluation on the 0, 1^st, 15^th, 30^th, 45^th and 60^th days. Lateral and ventro-dorsal radiographic view of the affected part of the spinal column were obtained. Variable levels of callus formation were observed during the healing of spinal fractures in all the dogs. Recurrence of subluxation was observed in one dog of Group-A on the 15^th post-operative day. Implant migration was observed one dog of Group-B on the 30th post-operative day. In Group-B, no significant change was visible in plain radiographs at the site of hemilaminectomy.
