Thirty windsucking horses were admitted in the last eleven years (1990–2000) for a surgical intervention at the Department of Surgery and Anesthesiology of Domestic Animals of the Faculty of Veterinary Medicine in Ghent. Twenty-one horse owners answered the follow-up questionary. The results after surgery (modified operation of Forssell) were good in 71.4% of the cases, with little postoperative complications. There was no predisposition for a certain age or sex although thoroughbreds were more often referred for surgical treatment. The etiology of this stereotypy and its treatments are discussed.
