Traumatic Multiple rib Fracture and Patella Ligaments Rupture in an Argentine Parade Horse-Case Report

The objective of reporting this case is to describe the clinical signs and postmortem findings associated with multiple rib fracture and patella ligaments rupture in a gelding used for ceremonial military parade with a view to improving diagnostic skill of practitioners for a quick and appropriate plan for managing chest and patella traumas. In this case, 7 years old, 500kg body weight, Argentine gelding slipped off concreted stable-floor while it was being led out for a routine riding exercise. At the time of first presentation (19 hours post-accident), the clinical findings were; congested bilateral ocular mucous membranes with jaundice, base-wide conformation of forelimbs, head nodding, bilateral twitching around shoulders, reluctance to move, off-feed and refusal to drink water. Hyperpnoea, tachycardia and hyperthermia were also observed. There were no evidences of bruises, swellings or localized pain on general inspection and palpation at the time of presentation. In subsequent days groaning, teeth grinding, intermittent sternal recumbency and ‘dog sitting’ position were observed until the gelding died in early hours of day 6, post-accident. Postmortem findings were; proximal 3rd un-displaced, simple fracture of ribs no. 2 to 18 (17 ribs) in the left hemithorax, jaundice, hemorrhagic thighs and stifles with ruptured left patella ligaments. Diagnosis of ‘Traumatic multiple rib fracture and patella ligaments rupture was made at postmortem. In conclusion, it was suggested that when adult horse falls, thorough clinical examination, ultrasonography or less revealing radiography should be conducted while assessing thoracic and patella traumas in horses as some of the serious signs may not manifest at the time of accident. This will enable equine practitioners to plan early for conservative, surgical or medical management regime thereby reducing fatality.
