Coxofemoral luxation in two foals wearing hindlimb casts.

This study discusses the cases of two foals, or young horses, that developed hip dislocations after wearing hindlimb casts. It theorizes that the dislocations probably occurred through clumsy standing attempts or being pushed by their mother with the affected limb getting trapped in a forward extended and awkward position.

Introduction

• This research paper investigates the complications arising out of the application of hindlimb casts in two foals.
• The specific complication studied is coxofemoral luxation, which is a medical term for hip dislocation.

Case Profiles

• The two foals had their casts applied for different durations – one for 6 days and the other for 9 days – before developing this complication.
• One foal had a cast on one hindlimb up to the proximal part of the tibia – the large bone in the lower leg, while the second foal had tube casts on all 4 limbs.

Potential causes of Coxofemoral Luxation

• The exact incidents leading to the dislocations were not observed directly. However, the researchers speculate that the luxations likely resulted from the foals’ unsteady attempts to stand, or due to the foals being pushed by the mare – their mother.
• The researchers postulate that during these incidents, the foals’ affected leg got trapped under their bodies in an abnormally extended and adducted (drawn towards the centerline of the body) position, thus leading to the hip dislocations.

Research Importance

• This research is significant because it explores potential drawbacks and risks associated with the use of hindlimb casts in young horses.
• The findings could be taken into consideration when deciding on the application of such casts in veterinary medicine, and potentially pave way for alternative treatments or additional safety measures to prevent such occurrences.
