Abstract

A retrospective study was carried out to investigate the prevalence and causes of laminitis affecting limbs other than the contralateral healthy
limb after orthopedic surgery in horses. Of 3,500 horses referred for orthopedic surgery at the Equine Clinic, Vetsuisse-Faculty, University
of Zurich, between 1992 and 2007, eight horses that developed laminitis in one or more limbs, but not primarily the contralateral
limb, were identified. The reasons for referral were synovial space infection (n = 4), pastern joint arthrodesis (n = 1), fracture of the central
tarsal bone (n = 1), bilateral stifle osteochondrosis (n = 1) and luxation of the superficial digital flexor tendon (n = 1). Postoperative
complications included infection of the surgery site (n = 1), severe postoperative pain (n = 2), postoperative myopathy (n = 1), urticaria
(n = 1) and cecal impaction (n = 1). The administration of analgesics was discontinued eight days after surgery because of urticaria in
one horse and one day after surgery because of cecal impaction in another horse. Seven of the eight horses were euthanized because of
severe laminitis. Elimination of infection and effective postoperative analgesia appear important in the prevention of laminitis. Severe postoperative
pain should be prevented with adequate, continuous and multimodal pain management. It should also be noted that laminitis
may occur in response to excessive weight bearing in limbs other than the contralateral limb after orthopedic surgery.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
