 Strain on the superficial digital flexors is greater when jumping higher fences, so horses may no longer be suitable for competitive jumping after damaging that apparatus.The effects of jumping on the hind legs can include injuries to the proximal, medial, or lateral branches of the suspensory ligaments.Jumping horses can also be at a higher risk of developing osteochondritis dissecans (OCD) or other arthritic conditions, even at a young age.
