A 5 yr old male neutered Labrador retriever was evaluated for an 8 wk history of a slowly progressive abnormal hind limb gait that did not respond to treatment with nonsteroidal anti-inflammatories.

Initial examination findings were mild pelvic limb ataxia and moderate right pelvic limb lameness. A computed tomography with a myelogram was performed and showed a suspected intramedullary spinal mass. MRI was conducted and supported the computed tomography with myelogram findings of a possible intradural spinal mass at L1.

Objectives: To compare the proportions of dogs with thoracolumbar disc extrusion that lose pelvic limb pain perception if surgery is performed on the day of admission or delayed overnight. To describe the outcome of those dogs that deteriorate to lose pain perception.

Objective: To describe low-field MRI findings associated with lumbosacral foraminal stenosis and radiculopathy and correlate these with clinical signs.

Study design: Retrospective study.

Animals: Client-owned dogs (n = 240) that underwent a clinical examination and standardized MRI protocol of the lumbosacral junction.

OBJECTIVE: To determine the effectiveness of durotomy as an adjunct to surgical decompression in dogs with thoracolumbar intervertebral disc herniation (TL-IVDH) and loss of deep pain perception (DPP) in the hind limbs.

STUDY DESIGN: Retrospective study.

ANIMALS: Dogs (n = 116) with TL-IVDH and loss of DPP treated with hemilaminectomy.

OBJECTIVE: To describe median manubriotomy to access the ventral aspect of the caudal cervical and cranial thoracic spine and report the outcomes in dogs with lesions affecting the spinal cord at C6-T2 vertebral bodies. To evaluate possible complications of this technique and clinical outcomes.
