Variation in palmaromedial articulations of carpometacarpal joints in Thoroughbred and Standardbred racehorses.

Background: Carpal conformation is an important factor in relation to joint soundness. The equine carpometacarpal joint (CMCJ) was reported to have variations in its three palmaromedial articulations. Lacking one or more of these articulations has not been radiographically evaluated in Thoroughbred (TB) and Standardbred (SB) racehorses.

First phalanx exostosis in traditional equestrian horses in Western Libya.

Background: Orthopedic diseases involving the forelimb fetlock joint of horses other than those used in professional racing have not been widely reported in the literature. One of these problems is the exostosis on the proximal forelimb phalanx (P1), which has not been reported previously in Western Libya.

Aim: The study aimed to investigate the prevalence of P1 exostosis in traditional equestrian horses (known locally as Sarj horses) of different breeds in Libya that participated in a special social event and described its clinical findings radiographic appearance.

Herniorrhaphy in two newborn lambs with omphalocele.

Background: Omphalocele is an uncommon congenital defect in the ventral abdominal wall. Its etiology and pathogenesis are not certainly approved despite the numerous theories.

Cases Description: Two newborn lambs with protruded membranous sacs from the umbilical region were presented.

Observations of sacrocaudal fusion in Greyhounds and other dogs.

Objectives: To describe the incidence and forms of nonpathological sacrocaudal fusion in racing Greyhounds and compare them with those in a variety of other domestic dog breeds.

Methods: This retrospective observational study used archived anatomical specimens from 81 racing Greyhounds and 10 Beagles, and archived clinical radiographs from 81 non-Greyhound dogs representing 37 other breeds. Dogs less than two years of age and dogs with evidence of soft tissue or osseous pathology involving the sacrocaudal region were excluded.

Effect of intravenous administration of romifidine on intraocular pressure in clinically normal horses.

Objective: To evaluate the effect of intravenous administration of romifidine on the intraocular pressure (IOP) in horses.

Animals Studied: Twenty-four horses with no ocular abnormalities.

Procedure: Horses were randomly assigned into two equal groups (treatment and control).
