Purulent necrotic dislocation of the hip joint associated with umbilical infection in a foal.

This research discusses a case of hip joint dislocation in a young horse, triggered by an umbilical infection that caused inflammation and subsequent pathological changes in the leg.

Case Summary

• The case involves a 42-day-old heavy draft horse that suddenly could not stand. It had notable swelling and a sense of heat in the left femoral region, typically symptoms that indicate internal issues.
• Audible friction from the left hip was presumed to be due to either a dislocated hip joint or a fractured hip bone. These assumptions were later confirmed through a CT scan.
• The CT scan revealed that the left hip joint was not in its proper position and that the left femoral head (top part of the thigh bone fitting into the hip socket) was disconnected.

Diagnosis and Findings

• After conducting a pathological autopsy, the diagnosis was determined: the foal had a fractured hip bone and femoral head with suppurative umbilical arteritis, a severe type of umbilical infection characterized by pus formation.
• The pathological changes in the umbilical artery and the hind leg were completely unilateral, affecting only one side, specifically the left side.
• The study suggests that this may mean that the left umbilical arteritis had spread into the blood circulation, resulting in inflammation (arthritis) and dislocation of the hip bone.

Conclusion

• The case is significant because it provides an insight into how an umbilical infection can lead to complications such as hip joint dislocation in foals.
• The research highlights the importance of quick detection and treatment of infections in young horses to avoid potentially dangerous systemic impacts.
