Good info on splints.

A common cause of behavioural issues in horses occurs when their splint bone (the long narrow bones that grow about 2/3 of the way down either side of the horses cannon bone) is damaged from a fracture, break or strain to the ligament attaching the splint to the cannon bone 🦴
Damage to the splint bone or attached ligament can happen from general concussion, a kick, a knock or strain from conformation faults. When this happens, a small bony protrusion can start to show as the site of injury. This is the bodies way of healing the area.
A splints healing process takes about 6-8 weeks of complete rest if the bone has been damaged, and about 3 months of complete rest if the ligament has been damaged. An X-ray can help diagnosis the affected area.
BEHAVIOURAL ISSUES:
Splints commonly cause the following issues:
◼️If the horse has damaged a hind splint bone they will start to rush and may get hot to ride.
◼️If a horse has damaged a front splint bone they will often begin stopping at jumps, most commonly doubles and triples because of the extra concussion required to navigate these obstacles. These horses will often jump great at home (especially if they are on a soft sand surface) but will often start randomly stopping at shows (more the case if the ground is hard or jarring to the site of injury).
NOTEWORTHY ITEMS
◽️Horses can occasionally be lame from a splint, but many injuries do not result in lameness.
◽️Splints take about three weeks to show up. So if your horses behaviour starts to change, reduce their workload and keep an eye out for any soft areas of swelling beginning to form beneath their knee or hock on either side of their cannon bone.
◽️Some splints are old and have finished the ossification (fusing) process. This means the splint has healed and the horse is good to be worked again.
◽️Sometimes the body will demineralise old splints and they can shrink or disappear completely over time.
◽️If the splint is new, the point of the protrusion is usually soft and squishy. If you pick up the horses leg, and gently palpitate the point of the injury and the horse pulls off the pressure then it is likely the splint is new and the horse needs immediate rest time.
◽️Many splints happen when a young horse is ridden or jumped on hard ground. This is because the ligament attaching the splint to the cannon bone hasn’t begun the fusing process yet, which usually happens as the horse matures. My rule of thumb is that if you can hear the horses hoof beats echoing as they trot, the ground is way too hard and they shouldn’t be ridden out of a walk, let alone be asked to jump or compete.
