Equine incoordination.

This research catalogue discusses a case study of an 11-month-old quarter horse colt suffering from equine incoordination, a neurological condition that affects a horse’s movement and balance. The article traces the progression of the colt’s condition, from initial signs to post-mortem examination, to study the etiological factors and characteristics of this disease.

Introduction

• The paper starts by shedding light on the prevalent insights that have been presented in the veterinary literature about equine incoordination. The causes have been variously attributed to heredity, nervous system lesions and osteoarthrosis.
• Recent studies have also pointed towards cervical osteo-arthropathies and angiopathies as significant causes.
• The case study documented in this report aims to present different aspects and stages of this complex condition.

History

• The colt, native to Oklahoma, USA, started showing signs of incoordination four months after its sale. Initial suspicions pointed towards a vitamin B deficiency, but treatment didn’t bring about significant improvements. Eventually, the colt exhibited incoordination in all four legs.

Signs

• Upon admission, the colt exhibited classic signs of equine incoordination, including staggering movement, difficulty in backing up and circling, and reluctance to do so.
• The colt’s condition rapidly worsened, and it was unable to stand without aid after four days.

Post-Mortem Examination

• The colt was euthanized five days post-admission.
• Cerebrospinal fluid was extracted, and radiographs of the neck were taken which showed narrowing of the subarachnoid space and misalignment of C4 vertebrae.
• The cervical portion of the spinal cord was carefully extracted and dissected. After removing the soft tissues and disarticulating the vertebrae, significant overgrowth was found on the ventromedial border of both cranial articular processes on C4, resulting in encroachment upon the lumen of the spinal canal.
• These findings were photographed, and changes in the angle of articular processes were recorded. The lesion noted was categorized as a type II lesion, indicating a pathological change due to disease.
