Negative palmar angle syndrome in racing horses
Early recognition and correcton can prevent this potentially career-ending pathology
Dec 01, 2010
If this condition is not treated appropriately, severe contracture of the heels can develop, followed by quarter cracks or heel fractures, either of which makes the management of NPAS more complicated and delays the return to soundness. Suppurating corns may also develop and can lead to proximal migration of the infection into the collateral cartilages and even the distal interphalangeal joint.Conclusion
NPAS is a treatable condition. Unfortunately, many affected horses that are not treated properly are retired, some after having undergone neurectomies because nothing else has made them comfortable. But with a little know-how and some patience, you can treat these cases and be rewarded for your efforts with a satisfied client and a happy horse.
