Pain originating from the tarsus is a common cause of lameness; however, there are limited descriptions of tarsocrural joint (TCrJ) pathology in mature horses. The objectives were to describe the clinical features and diagnostic imaging findings of skeletally mature horses with TCrJ pathology, and to determine the clinical outcome. Case records and images of 17 horses examined at the Animal Health Trust, between 1997 and 2010, with pathology associated with the TCrJ were evaluated and follow-up information obtained.
Lameness is the most commonly diagnosed condition in equine veterinary practice. To examine whether variations in management and husbandry strategies in riding schools could influence wastage due to orthopaedic injury schools with high (HUIO) or low (LUIO) insurance claims for orthopaedic injuries (as an indirect measure of wastage) were compared epidemiologically using an extensive questionnaire and field study visits.
Objectives To review eight horses diagnosed with idiopathic haemarthrosis and to describe the intra-articular use of yttrium-90 (90Y) and methylprednisolone acetate (MPA) in recurrent haemarthrosis cases. Design Retrospective case series. Method The medical records, diagnostic images, histopathology and outcome of all horses diagnosed with idiopathic haemarthrosis between 1998 and 2010 were reviewed. Results Four Thoroughbred racehorses with haemarthrosis of the antebrachiocarpal joint had severe acute lameness (median, grade 4) and marked joint effusion after high-speed exercise.
Reasons for performing study: The flexion test is routinely used in lameness and prepurchase examinations. There is no accepted standard for duration of flexion or evidence that interpretation of results would differ with different durations of flexion.
Hypothesis: There will be no difference in interpretation of proximal hindlimb flexion for 5 or 60 s.
Reasons for performing this study: Intra-articular ethanol has been described to promote distal tarsal joint ankylosis. Its use and results in clinical cases affected by osteoarthritis (OA) have not been reported.
Objectives: To describe and evaluate the results of treatment of distal tarsal joint OA by facilitated ankylosis stimulated by intra-articular ethanol injection.
Reasons for performing study: Lyophilised products from green-lipped mussel (Perna canaliculus[LPPC]) are used to orally treat horses with osteoarthritis (OA). However, no randomised, controlled or double-blinded studies on the efficacy of this treatment in horses have been reported to date.
Objective: To investigate the effects of a unique LPPC (Biolane)1 in improving clinical signs of OA in the fetlock.
Objective Conventional imaging modalities can diagnose the source of foot pain in most cases, but have limitations in some horses, which can be overcome by using magnetic resonance imaging (MRI). However, there are no reports of the MRI appearance and prevalence of foot lesions of a large series of horses with chronic foot lameness. Methods In the present study, 79 horses with unilateral or bilateral forelimb lameness because of chronic foot pain underwent standing low-field MRI to make a definitive diagnosis.
Objective—To assess the analytic sensitivity of an inertial sensor system for detection of the more severely affected forelimb in horses with bilateral lameness.
Animals—18 adult horses with forelimb lameness.
