Upward fixation of the patella in the horse. A retrospective study. The objective of the present study was to assess the incidence of upward fixation of the patella (UFP) in different types of patients and to evaluate the outcome of conservative and surgical treatment for correcting this condition. A particular attempt was made to find out whether corrective trimming and/or shoeing (CTS) is efficient in the conservative treatment of UFP, and whether a longer postoperative resting period reduces the risk of complications after medial patellar desmotomy (MPD). Medical records of 78 horses with intermittent or permanent UFP were analyzed retrospectively. Young an...
Genetic modification of chondrocytes with insulin-like growth factor-1 enhances cartilage healing in an equine model. Gene therapy with insulin-like growth factor-1 (IGF-1) increases matrix production and enhances chondrocyte proliferation and survival in vitro. The purpose of this study was to determine whether arthroscopically-grafted chondrocytes genetically modified by an adenovirus vector encoding equine IGF-1 (AdIGF-1) would have a beneficial effect on cartilage healing in an equine femoropatellar joint model. A total of 16 horses underwent arthroscopic repair of a single 15 mm cartilage defect in each femoropatellar joint. One joint received 2 x 10(7) AdIGF-1 modified chondrocytes and the contralateral...

Histological evaluation of the equine larynx after unilateral laser-assisted ventriculocordectomy. Trans-endoscopic laser surgery, such as unilateral laser-assisted ventriculocordectomy (LVC), has gained popularity in the treatment of RLN because a laryngotomy incision or general anaesthesia are not required. However, removal of the vocal fold and ventricle takes considerable laser energy and could cause collateral tissue damage, including injury to the adjacent laryngeal cartilages. Objective: To document the histological effects of laser surgery on laryngeal tissues in horses that have undergone LVC for the treatment of laryngeal hemiplegia (LH). Methods: Six horses were used: 4 with expe...
In search of clinical truths: equine and comparative studies of anatomy. The importance of correlating anatomical studies with diagnostic and therapeutic approaches in practice has long been recognised. Such studies in the horse have, until recently, lagged behind this discipline in human medicine and surgery. Clinical techniques by which this correlation is achieved include radiography, ultrasound, computed tomography and magnetic resonance imaging. This review presents published literature on the subject and, in addition, describes the part played by plastination, a recently developed technique for the preservation of biological specimens. In this, tissue fluids ...
Bilateral Polydactyly in a foal. The following case report describes the diagnosis and surgery of bilateral polydactyly of unknown origin in a colt. A 7-month-old Berber colt was referred for cosmetic and curative excision of supernumerary digits. Radiographic examination revealed bilateral polydactyly and welldeveloped first carpal bones. Surgery consisted of an osteotomy of both second metacarpal bones combined with an amputation of the supernumerary digits.

Structural and biomechanical aspects of equine sacroiliac joint function and their relationship to clinical disease. Pain originating from the sacroiliac joint (SIJ) in horses has long been associated with poor performance, yet specific diagnosis of sacroiliac dysfunction (SID) has been difficult to achieve. Clinical presentation of SID appears to fall into two categories. The first, presenting as pain and poor performance, is responsive to local analgesia of periarticular structures with poorly defined pathology. The second presents primarily as poor performance with bony pathological changes as a result of chronic instability. Diagnostic tests based on biomechanics as well as manual provocation for SIJ pai...
