The plantar angle describes how the position of the third phalanx relates to the solar surface of the hind foot. A negative plantar angle has been linked to pathological conditions causing lameness in the hindlimb and is therefore undesirable in horses. The plantar angle is commonly determined...

In this study, Thoroughbred horses at the 2016 Keeneland September Yearling Sale and 2017 Fasig-Tipton and Ocala Breeders' 2-year-old sales in the USA were subjected to radiographical examination of the sesamoid bones. Horses included 2508 yearlings and 436 two-year-olds. Yearling findings...

Finding an appropriate location for perpendicular positioning of the X-ray machine to produce zero lateromedial (ZLM) and zero dorsopalmar (ZDP) carpal images (views) and finding an acceptable range of rotational variations for measurement of carpal conformational parameters were two major...

HISTORY: Suspensory ligament injury associated with avulsion or crescent fracture of third metacarpal or metatarsal bone is a common injury in racehorses. Lameness is known to be the most common clinical sign of these horses. CLINICAL FINDING: The present article investigated two avulsion fractures ...

An 18-year-old Quarter Horse mare was evaluated because of moderate left forelimb lameness of 4 weeks' duration. The clinical evaluation and diagnostic perineural analgesia localized the lameness to the distal portion of the left forelimb. There was swelling on the dorsal and lateral aspect of the...

OBJECTIVE: To determine and compare the effect of hoof boots (HBs) and shoes with a toe extension on stance duration, ground reaction force, and sole length in contact with the ground in nonlame horses during walking. ANIMALS: 6 nonlame Standardbreds. PROCEDURES: Force plate gait analyses of the ...

Background: Osteochondral fragmentation of the proximal phalanx (DPP1 fragment) is a common finding in the racehorse. Whilst radiographic assessment has been reported to lack diagnostic sensitivity, ultrasonographic examination has been documented to be extremely sensitive for identification of...

A 14-year-old Irish sport horse presented to our institution with a history of right forelimb lameness and left-sided back pain. Radiography and nuclear scintigraphy were performed under sedation and the horse was diagnosed with overriding dorsal spinous processes, also known as kissing spine...

A 20-year-old Quarter horse gelding was referred for evaluation of an acute onset non-weight-bearing right forelimb lameness. Marked soft tissue swelling was apparent over the right scapula and shoulder region; no crepitus was palpable. A complete transverse fracture of the scapular neck was...

Objective: To describe the effects of distal limb immobilization and remobilization in the equine metacarpophalangeal joint. Study design: Randomized, prospective experimental study. Animals: Eight healthy, skeletally mature horses. Methods: One forelimb of each horse was immobilized in a...
