Does Your Horse Need His SI Joint Checked?
The sacroiliac (SI) region plays an important role in transferring power from the hindquarters through the back. When a horse is uncomfortable in this area, the signs aren't always obvious, but you might notice:
• Back soreness or sensitivity when grooming or saddling
• Difficulty picking up or holding a lead
• Trouble engaging the hind end
• Reluctance to go forward
• Bucking, kicking out, or other behavior changes under saddle
• Difficulty with transitions, collection, or jumping
• Unevenness behind without an obvious lameness
• A noticeable drop in performance
If your horse is consistently sore through his back or SI area, it's worth having your veterinarian evaluate him and discussing whether further diagnostics, including X-rays or other appropriate imaging, are warranted. Back pain can have several causes, and soreness in one area doesn't necessarily mean that's where the original problem started.
When SI-region pain is identified, SI injections may be part of the treatment plan. Injections can provide significant relief for many appropriately diagnosed horses and may help them move more comfortably. Getting a proper veterinary diagnosis first is important.
Don't just write off a sore back as normal. Investigate it, involve your vet, and follow through with diagnostics and treatment when they're recommended. Sometimes addressing SI discomfort can make a remarkable difference in how a horse feels and performs.
