[Laminectomy in the dog for experimental purposes--a technical comment].

The reach of the lumbar vertebral column in the dog should be preferred in operations on the spinal marrow after own experiments. A better survey during the operation and a smaller risk of contusion of the spinal marrow by surgical instruments passed through there by reason a wider spinal canal a more voluminous spinal marrow. This method is more expensive, however more advantageous than a laminectomy in the reach of the thoracic spine because there exist some differences in the form of the bodies of the vertebra in humans and dogs.
