<unk> , also known clinically as lordosis, refers to abnormal bent-back postures in humans and in quadrupeds, especially horses. Extreme lordosis can cause physical damage to the spinal cord and associated ligaments and tendons which can lead to severe pain. Moderate lordosis does not generally impact a horse’s usefulness and does not necessarily cause lameness.
