Proximal interphalangeal joint ankylosis in an early medieval horse from Wrocław Cathedral Island, Poland.

The research article discusses the examination of horse bones from the 11th century, found in Poland, which showed signs of a joint disease. The results suggest the horse likely suffered from lameness for several months before its death.

Introduction

• The research is centered on the pathological examination of a medieval horse’s skeletal remains, specifically the first and second phalanges (bones in the hooves).
• The specimen was found during an archaeological excavation at Wrocław Cathedral Island in Poland and dates back to the 11th century.

Examination Methods and Findings

• The researchers used gross examination, radiography, and computed tomography (CT) scans to study the condition of the specimen’s bones.
• They discovered signs of osteoarthritis in the proximal interphalangeal joint (the joint between the two phalanges), along with partial ankylosis (joint stiffness).
• By comparing their findings to modern horses with similar conditions and to current literature on the subject, they deduced that the horse was likely lame for at least several months before it died.
• However, they could not definitively determine the degree to which the horse’s work ability was compromised during its lifetime.

Treatment and Management in Medieval Times Vs Modern Times

• The researchers noted that based on current medical knowledge, it would have been near impossible to successfully treat such a condition during the medieval period when the horse lived.
• In contrast, today, horses with similar pathologies can be managed reasonably well, especially after their joints have become ankylosed (fused).

Cultural Implications of the Findings

• The findings raise questions about the cultural practices of the time – primarily why a horse with such a significant limitation would have been kept for likely a considerable period.
• This suggests a possible socio-cultural context that valued preserving the animal’s life or lacked the necessary knowledge to diagnose and potentially euthanize the animal in severe pain or discomfort.
