A relationship exists between foot conformation and movement asymmetry with decreasing hoof width and hoof length related to increasing amount of movement asymmetry. In the population of horses studied here--deemed to be 'well functioning' by their owners/riders--foot placement was found to be independent of movement asymmetry and, to a large extent, independent of foot conformation.
Pre-surgical investigation of digital flexor tendon sheath pathology remains challenging with current standard imaging techniques. The aim of this prospective, anatomical, pilot study was to describe the anatomy of the equine hind limb digital flexor tendon sheath using a combination of computed tomography (CT) and computed tomographic contrast tenography in clinically normal cadaver limbs. Ten pairs of hind limbs with no external abnormalities were examined from the level of the tarsometatarsal joint distally. Limbs initially underwent non-contrast CT examination using 120 kVp, 300 mAs, and 1.5 mm slice thickness. Sixty millilitres of ioversol iodinated contrast media and saline (final concentration 100 mg/ml) were injected using a basilar sesamoidean approach. The computed tomographic contrast tenography examination was then repeated, before dissection of the specimens to compare gross and imaging findings. The combined CT and computed tomographic contrast tenography examinations provided excellent anatomical detail of intra-thecal structures. The borders of the superficial and deep digital flexor tendons, and the manica flexoria were consistently identifiable in all limbs. Detailed anatomy including that of the mesotenons, two of which are previously undescribed, and the plantar annular ligament were also consistently identifiable. Dissection of all 10 pairs of limbs revealed there to be no pathology, in accordance with the imaging findings. In conclusion, the combination of CT and computed tomographic contrast tenography may be useful adjunctive diagnostic techniques to define digital flexor tendon sheath pathology prior to surgical exploration in horses.
Summary Metoclopramide is used for the management of post operative ileus in horses for its gastrointestinal prokinetic effects. Adverse extrapyramidal signs have been reported following its use in horses as well as in man. This report describes the clinical signs exhibited during an adverse reaction suspected to be associated with subcutaneous administration of 0.25 mg/kg bwt metoclopramide at 6 h intervals.
Solitary osteochondromas are a relatively infrequent cause of lameness in the horse, most commonly occurring in the caudal distal radial metaphysis, with sparse reports in other locations. Their presence adjacent to a synovial sheath frequently results in intra-thecal tendinous laceration and resultant synovial effusion. Surgical excision in combination with arthroscopic debridement of the tendinous pathology offers the best prognosis for soundness. This report details the successful treatment of a caudodistal tibial osteochondroma using a combination of open surgical excision and tarsal sheath tenoscopy.

HOPKINS 20The relationship between working equids and women in developing countries Foreword and AcknowledgementsThis supplement contains a diverse selection of abstracts addressing clinical research from many disciplines. Topics that are particularly well represented this year include endocrinology, laminitis, critical care and spinal disease. The only consistent feature is the very high standard. This year, BEVA has devoted an extra two sessions to abstracts, but despite this increased time, the selection process was difficult due to the large number of excellent submissions. Over the last 10 years or so, Clinical Research Abstracts have progressively risen in stature and it is now the go-to place for cutting-edge, clinically relevant information delivered in a concise and highly professional manner. This is where Congress attendees will find the snippets of information to take straight back to practice to effect changes in the way of case management. By publishing this supplement in EVJ, BEVA hopes to make this new and relevant research available to those who have not been able to attend the Congress in person. Perhaps, this supplement will inspire some readers to make the trip next year. This year's BEVA Congress Clinical Research Abstracts have involved a more detailed review process than in the past. Brief reports on the abstracts under consideration were obtained from two peer reviewers before being graded, and ultimately selected by a subset of the Congress Scientific Programme Guardians: Renate Weller, Tim Barnett, Tom Witte, Neil Hudson and Janny De Grauw. We hope that the authors will find the feedback from reviewers constructive. I am extremely grateful to the peer reviewers, the CRA sub-committee and to James Crabtree and Matt Smith who completed the Programme Guardian team. David Hicks, Jane Woodley, Sue Wright and Anne Catchpole also deserve thanks for their contributions during the submission, appraisal and production phases of this Special Issue of EVJ.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
