Objective—To determine outcome of Standardbred racehorses with moderate to severe midbody suspensory ligament desmitis (MSD) treated by means of ultrasound-guided intralesional injection of a single dose of platelet-rich plasma (PRP) followed by a program of gradually increased exercise.

Design—Nonrandomized clinical trial.

Animals—9 Standardbred racehorses.

Objective—To determine whether clinically effective concentrations of methylprednisolone or triamcinolone can be achieved in the navicular bursa after injection of methylprednisolone acetate (MPA) or triamcinolone acetonide (TA) into the distal interphalangeal joint (DIPJ) and whether clinically effective concentrations of these drugs can be achieved in the DIPJ after injecting the navicular bursa with the same doses of MPA or TA. Animals—32 healthy horses.

Reasons for performing study: Constriction of the digital flexor tendon sheath (DFTS) and its contents by the palmar/plantar annular ligament (PAL) is well recognised. However, primary injury of the PAL has not been well documented.

Objectives: To describe the clinical features of PAL injury, determine its prevalence with or without subcutaneous fibrosis and/or concurrent injury within the DFTS, and assess response to treatment.

Tiludronate is a compound in the bisphosphonate class of drugs. The main pharmacologic action of bisphosphonates is to inhibit bone resorption; they cause osteoclast apoptosis and disrupt intercellular trafficking of pro-inflammatory mediators. Bisphosphonates are used to treat humans with diseases such as osteoporosis and Paget's disease. Recently tiludronate has been studied as a treatment for bone resorptive diseases in horses. Tildren, an injectable form of tiludronate made for the horse, has been licensed to treat navicular disease and distal tarsal osteoarthritis in Europe.

The skill to diagnose lamenesses in horses is paramount for every equine practitioner. Early recognition of locomotor deficiencies plays a central role in sports medicine management, preventing deterioration of the disease or catastrophic injuries. Horses use characteristic compensatory movements of specific body parts to decrease loading of the affected limb. This article describes the underlying changes in intra- and interlimb coordination and the resulting load redistribution between the limbs.

Sacroiliac lesions are commonly suspected in sport- and racehorses. Injection of the sacroiliac (SI) area can be performed for diagnostic purposes and/or for treatment of SI pain. Because of the deep location of the SI joint, blind injections may be unsafe. The purpose of this paper is to present how to perform ultrasonographic guided injection of the SI area using cranial and caudal approaches. With this technique drugs can be injected close to the SI joint and technical errors (needle implantation in the sciatic nerve, injection in the vertebral canal or in the rectum) can be avoided.

Proximal hindlimb lameness remains a diagnostic challenge despite modern imaging techniques. In the case described here, a fracture of the ischium produced false negative results on initial ultrasound and scintigraphy examinations, despite a 14 day delay from onset of clinical signs to the time of the nuclear bone scan. However, the history and clinical examination were strongly suggestive of a pelvic injury and this was only confirmed by the use of a novel radiographic technique.

A retrospective study of 63 horses diagnosed with limb cellulitis between 1994 and 2005 was conducted. They all had an acute onset of painful, generalised limb swelling, and a clinical diagnosis of limb cellulitis was made by the attending clinician. None of the horses had more than one limb affected.

Abstract:Reasons for performing study: There are no detailed studies describing a relationship between hindlimb lameness and altered motion of the back.  Objectives: To quantify the effect of induced subtle hindlimb lameness on thoracolumbar kinematics in the horse.
