Objective: To evaluate the intervertebral disk, vertebral endplates, and spinal cord for perioperative changes secondary to percutaneous laser disk ablation (PLDA) and correlate findings to clinical outcomes in dogs receiving thoracolumbar PLDA.

Study design: Blinded study.

Animals: Thirty dogs.

Objective: To evaluate the change in ex vivo biomechanical properties of the canine cervical spine, due to an intervertebral cage, both as a stand-alone device and in combination with plates.

Study design: Experimental ex vivo study.

Animals: Cervical spinal segments (C5-C7) from eight canine cadavers.

Authors: Stephen P Spence, Sarah K Israel

Objective: To compare the incidence of MRI lesions between dogs weighing < 15 kg (33 lb) and dogs weighing ≥ 15 kg.

Animals: 494 dogs with clinical signs of thoracolumbar disease.

Case description: 4 dogs, 7.5 to 10 years of age, were presented for evaluation of signs of chronic cervical pain and forelimb lameness secondary to cervical foraminal intervertebral disk protrusion (IVDP). All dogs were refractory to ≥ 2 weeks of conservative management including strict rest and pain management with anti-inflammatory drugs, methocarbamol, and gabapentin.
