“…Imaging studies of the musculoskeletal system are now relatively commonly performed in clinical zoologic medicine. 5 No comprehensive information has, however, been published on the normal osteology and radiologic anatomy of the suricate. This study provides a morphologic description of selected unique features of the normal osteology and correlative radiologic anatomy of the thoracic limb of the suricate, in comparison to domestic carnivores.…”

The purpose of the study was to identify unique features of the normal osteology and radiologic anatomy of the thoracic limb of the meerkat or suricate (Suricata suricatta), as no comprehensive information has been published. Bone specimens of 19 suricates were studied. Individual bones of the manus of one preserved carcass were studied in situ. Radiographic evaluation was performed in six animals. Comparisons to domestic carnivores were made and functional morphologic changes were identified. A suprahamate process was present on the scapula spine. Both supratrochlear and supracondylar foramina were present in the distal humerus, with a small Fossa coronoidea seen cranially. The medial epicondyle was markedly larger than the lateral epicondyle. The Tuberositas radii was located caudally. The proximal end of the olecranon was prominent medially. The large medial coronoid process had an extensive proximal articulation facet for the humeral trochlea. The ulna styloid process articulated with the ulnar and accessory carpal bones. The manus was similar to that of domestic carnivores; however, Os metacarpalis I was markedly reduced with the absence of the first digit. There were seven carpal bones. Os carpi radiale was the largest, with a large palmaro-medial process and a small sesamoid bone present medially. Ossa metacarpalia II-V and corresponding phalanges were slender, with an elongated Processus unguicularis (third phalanx) present. Radiologic findings demonstrated increased mobility of the scapula and shoulder joint, with ease of abduction. On the cranio-caudal view of the humerus and elbow joint, the distal radius and manus were consistently rotated in a supinated position. Morphologic changes were identified for the enhanced, predominant function of the shoulder, elbow, carpal, and digital flexor muscles associated with superior digging ability, and supination of the antebrachium and manus. Reference values for size parameters of the long bones are reported. The findings will assist in clinical zoologic medicine and paleozoologic studies.

“…Contrast radiography studies can be used in the diagnosis of gastrointestinal disorders of reptiles, as well as indirectly for other viscera such as the liver and reproductive tract [7]. Single- and double- contrast agents are considered as the primary diagnostic methods for imaging the stomach and bowels of wildlife and zoo animals [22]. In addition to illustrating the gastrointestinal tract, contrast media can also be used to measure gastrointestinal transit times [23, 24].…”

Specific anatomy and radiographic illustration of the digestive tract and transit time of two orally administered contrast media in Inland bearded dragons (Pogona vitticeps)

et al. 2019

The aim of this study was to describe the specific gross and radiographic anatomy of the digestive tract of inland bearded dragons ( Pogona vitticeps ). Eleven bearded dragon cadavers of both sexes (6 females, 5 males) were dissected to examine, measure, and document the specific gross anatomy of the alimentary canal. Measurements collected from the cadavers included snout-vent length, total length of the alimentary canal, and the lengths of the individual sections of the gastrointestinal tract, including the esophagus, stomach, small intestine, ampulla coli, isthmus coli, rectum, and the distance from the coprodeum to the vent opening. Twenty-two healthy adult bearded dragons (13 females, 9 males) maintained under standardized husbandry conditions underwent a physical examination, blood collection, and whole-body dorsoventral and lateral survey radiographs; these animals were used to provide the radiographic images of the complete digestive tract. For the subsequent contrast passage studies, two different contrast media, barium sulfate (BaSO 4 , Barilux suspension) and an iodinated ionic radiocontrast agent (Sodium meglumine amidotrizoate [SMAT], Gastrografin), were used. Water-diluted Barilux suspension (dose 9 ml/kg) was administered orally to 5 bearded dragons, while Gastrografin (dose 5ml/kg) was administered orally to 21 bearded dragons. Four animals were used for both contrast media studies, but received a break of four weeks in between. Dorsoventral and laterolateral radiographs were collected at 0 (baseline), 15, 30, and 45 minutes and 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 30, and 36 hours after each contrast medium was administered. Both contrast media were found to illustrate the alimentary tracts in the adult bearded dragons. Transit time was substantially faster with SMAT, and SMAT illustrated the entire gastrointestinal tract within 36 hours; BaSO 4 did not fully illustrate the gastrointestinal tract in 36 hours. These results might serve as a guideline for the interpretation of subsequent contrast studies in this lizard species.

“…Entretanto, estudos sobre esqueletos pós-cranianos de canídeos sul-americanos são escassos desde as análises de Hildebrand (1954). Além disso, pouco se conhece sobre a anatomia de espécies silvestres para procedimentos de diagnóstico e tratamento em zoológicos (Stoskopf 1989).…”

The forelimb is the part of the post-cranial skeleton that provides more information about locomotion and life habits of a species. The objective of this study was to perform a detailed macroscopic, comparative, radiographic and osteometric investigation of the thoracic limb of Lycalopex gymnocercus. Twenty-four adult specimens collected dead from roadkill were studied. Analysis included macroscopic and comparative descriptions to other canids, radiographic images for recognition of trabeculation patterns and topographical arrangement of bones, linear and three-dimensional measurements, and histological evaluation of the clavicles. The forelimb skeleton of L. gymnocercus presented morphological and functional adaptations in every segment for a specialized cursorial locomotion and some ability to pronation and supination for capture of small vertebrates. There was a tendency for the bones to be longer in males, especially in the distal end of humerus, presumably to fixation of stronger antebrachial muscles. The vestigial clavicle bone was found in all the specimens, had a predominantly cartilaginous nature and was significantly larger in males. The basic conformation of the forelimb skeleton was similar to that of domestic and wild canids described in the literature, although peculiar characteristics of L. gymnocercus have been found.
