Problems with the back
Back problems are common in horses, but the usual presentation is one of poor performance rather than a localised expression of pain. The conditions can be primary, or can be a result of lameness originating elsewhere, ill fitting tack or conditions of the skin. The spine of the horse is not particularly flexible compared with other species such as dogs, but it is probably that inflexibility which allows us to ride horses in the way that we do.
Assessing the degree of back pain can be difficult in many cases. Some horses will continue to perform despite a low grade discomfort, whereas others appear to be very sensitive and resent any pressure along the spine. The examination must be methodical and thorough; it relies as much on eliminating other causes of reduced performance as it does on finding a precise focus of pain. There also appears to be a wide range of pain thresholds linked to individual temperaments.
History of the condition: Reduction in the level of performance Duration of the problem; often there is a gradual onset Can also be associated with a known accident Underlying lameness in one or more legs Losing the ability to jump Difficulty when putting on rug, grooming back or tightening girth Resentment of carrying a rider Head shaking and tail swishing Evidence of saddle sores and other skin conditions Poor saddle fit History of a fall History of tying up

Examination The examination includes a visual inspection, followed by both palpation and manipulation of the back. These two techniques will examine different aspects of the spine and its associated structures and will help identify which other examination procedures need to be employed. The visual inspection will identify imbalance in appearance and any muscle wastage. A good history should be taken to identify if this problem has occurred before, along with the type and intensity of work in which the horse is participating. In general, bone issues tend to
