Trauma with neurologic sequelae.

This research paper sheds light on spinal cord injury (SCI) in horses, exploring its primary causes, the processes involved in the condition, the role of secondary trauma, and its management. The work also discusses possible medical therapies borrowed from human medicine that may prove beneficial for equine patients.

Causes of Spinal Cord Injury (SCI)

• The main cause of SCI in horses is physical trauma that can result from several incidents such as rearing and falling backward, collisions, kicks, and slipping.

Pathophysiology of SCI

• The pathophysiology of SCI constitutes a primary mechanical injury that is followed by a series of secondary events.
• These secondary events involve microvascular ischemia (deficiencies in blood supply), oxidative stress, excitotoxicity (cell damage due to excessive stimulation by neurotransmitters), ion dysregulation, and inflammation.

Impact of Secondary Injury

• The severity of the secondary injury often determines the extent of restoration of neurological function.
• The trauma indirectly caused by the injury often creates more significant damage than the initial mechanical injury, making recovery more challenging.

Clinical Signs of SCI

• The clinical signs following a SCI usually depend on the location of the lesion and the relative amount of damage sustained by the gray and white matter of the spinal cord.

Management of SCI

• Acute management of a SCI in horses should involve optimizing the oxygen supply to the injured tissues.
• This is crucial as it aids in minimizing the extent of tissue damage and aids in the recovery process.

Potential Therapies for SCI

• The research also touches on promising medical therapies that have shown potential in human medicine, and their likely efficacy when applied to horses.
• The introduction of such therapies might revolutionize the treatment and management of SCI in horses, potentially improving recovery outcomes.
