Aspectos ultrassonográficos, anatômicos e histológicos normais da articulação metacarpofalangeana equina

Abstract

The purpose of this study was to describe and characterize the equine metacarpophalangeal joint structures through ultrasonographic, anatomical and histological analysis. Seventy forelimb specimens were obtained from a slaughterhouse and submitted to ultrasonographic evaluation. Thirty specimens without ultrasonographic detectable lesions were selected for dissection and subsequent anatomical and histological evaluation. Criteria such as size, shape, architecture and echogenicity were observed in order to characterize normal ligaments, tendons, joint capsule and articular cartilage of the metacarpophalangeal joint.
