[Ataxia and pruritus in a pony due to a cervical vertebral fracture].

This study presents a case of a mini-Shetland stallion that showed symptoms of ataxia (lack of muscle control) and localized itching (pruritus) in the anterior neck region, which were found to be associated with an old fracture at the C2 cervical vertebral location causing spinal cord compression. The researchers suggest the injury and ensuing symptoms bear similarities to the ‘contusio cervicalis posterior’ seen in humans.

Case Presentation

• The study focuses on a mini-Shetland stallion that was found showing symptoms of pruritus localized to the anterior neck. The horse was also observed to display signs of ataxia or lack of muscle control and balance.

Clinical Examination and Diagnosis

• Upon detailed clinical examination of the pony, and using diagnostic imaging techniques including pre and post-contrast computed tomography (CT), it was discovered that the pony was suffering from spinal cord compression. This condition was linked to an old fracture at the C2 cervical vertebra of the horse’s spine.

Probable Cause and Comparison

• Based on the observed symptoms and the results of the medical examination, the researchers came to the conclusion that the ataxia and localized pruritus in the pony could have been caused by the old cervical vertebral fracture leading to the compression of the spinal cord.
• In drawing a parallel to human conditions, the research points out the resemblance of this case to ‘contusio cervicalis posterior,’ a condition seen in humans. This refers to a trauma to the spinal cord that can cause pruritus or itching sensation in the associated dermatome – the specific area of the skin that is supplied by nerves from a single spinal root.
