Computed tomographic examination of the locomotor apparatus of horses – a review

Abstract

ZusammenfassungDie Computertomographie (CT) hat sich in den letzten Jahrzehnten auch in der Pferdemedizin zu einem wichtigen diagnostischen Hilfsmittel entwickelt. Durch ihre hohe Kontrastauflösung liefert sie vor allem im Bereich des Knochens exzellente Bilder, aber auch Weichteile lassen sich immer besser darstellen. Auf dem Gebiet der Orthopädie wird die CT geschätzt, da sie überlagerungsfreie Schnittbilder und rekonstruierte dreidimensionale Aufnahmen erstellt, die die Bewertung von Lokalisation, Ausmaß und Charakter einer Erkrankung verbessern. In der folgenden Arbeit werden die wichtigsten Veröffentlichungen zur Computertomographie im Bereich des Bewegungsapparates des Pferdes aus den vergangenen 30 Jahren zusammengetragen.Schlüsselwörter: Computertomographie, Orthopädie, Lahmheit, Diagnostik, Pferd Computed tomographic examination of the locomotor apparatus of horses -a reviewTodays computed tomography (CT) is a well established diagnostic tool in equine medicine. Due to todays high resolution, detailed images can be obtained especially of bony structures, and the quality of soft tissue images is steadily increasing. The advantages of computed tomography for the diagnosis of orthopedic patients lie in the production of non-overlapping image slices and the possibility of threedimensional reconstruction. These improve the assessment of location, dimension and character of the disease process. In this paper we have compiled the major puplications concerning computed tomography of the equine locomotor apparatus from the past 30 years.

Computed Tomography and Cross Sectional Anatomy of the Metacarpus and Digits of the One-humped Camel and Egyptian Water Buffalo

“…In accordance with some authors (Barbee & Alien, 1987;Peterson & Bowman, 1988;Dick, 1995;Whitton et al, 1998;Arencibia et al, 2000;Probst et al, 2005;Vanderperren et al) in horse, in bovine (Raji et al), in small ruminant (Bahgat, 2007), in dog (Fike et al, 1981(Fike et al, , 1984Feeny et al, 1991;Ottesen & Moe) and in human (Gehrmann et al) the CT provides good discrimination between bone and soft tissue architectures. Thus the computed tomography (CT) has become an important diagnostic imaging modality in the diagnosis of the musculoskeletal disorders (Bienert & Stadler, 2006).…”

Computed Tomography and Cross-sectional Anatomy of the Normal Dromedary Camel Tarsus (One Humped Camel)

“…Computed tomography allows cross‐sectional imaging without bone and soft tissue overlap. Furthermore, three‐dimensional rendering of the area of interest and multiplanar reformatting can yield better anatomic orientation of the area of interest and provide for more sensitive detection and characterization of disease extension (Tucker and Sande, ; Bienert and Stadler, ). Computed tomography has proved to be useful in the evaluation of stress‐induced bone remodelling, focal bone lesions, defining complex intra‐articular fractures, subchondral bone sclerosis and other subchondral bone lesions such as osteochondritis dissecans of the talus and preoperative planning for fracture repair (Gielen et al., ).…”

Radiographic and Computed Tomographic Anatomy of the Fetlock, Pastern and Coffin Joints of the Manus of the Donkey (Equus asinus)

“…The CT provides good discrimination between bone and soft tissue architectures. Thus the computed tomography (CT) has become an important diagnostic imaging modality in the diagnosis of the musculoskeletal disorders (Bienert & Stadler, 2006). The coffin joint comprised of the distal phalanges, the navicular bone, the impar ligament and the collateral sesamoidean ligament (CSL).…”
