Comparative morphological interpretations on the bones of the pelvic limb of New Zealand rabbit (Oryctolagus cuniculus) and domestic cat (Felis domestica)

Abstract

Objective: Regarding the displaying of the main differences between the pelvic limb of rabbit and cat. Materials and methods: Our work was performed on 10 New Zealand rabbits ( Oryctolagus cuniculus ) and domestic cats ( Felis domestica ) with variable ages and of both sexes. After weighing of the animals, sedation, and anesthesia, the animals were examined radiographically. The bones of the pelvic limb were prepared, measured for its length/cm then described and compared. Results: The iliac tuberosity and the conversion of the acetabular notch into foramen were characteristics of Os coxae of the rabbit. The intertrochanteric crest was detected on the femur of the cat. In the rabbit, the leg interosseous space was located in the proximal third of this region while in the cat, it was extended along its length. The first metatarsal was undeveloped in the cat but was absent in the rabbit so metatarsal were four in the rabbit and five in the cat. The digits of the pelvic limbs in both animals were four in number. The distal sesamoid was single, transversely situated, and shuttle-shaped in rabbit but it was absent in cat. Conclusion: So, the chief points of variation between the pelvic limb bones of rabbit and cat enabled us to keep away the commercial fraud and facilitated their use as an animal model for education purposes.

Comparative Anatomy of the Forearm and Hand of Wildcat (Leopardus geoffroyi), Ocelot (Leopardus pardalis) and Jaguar (Panthera onca)

“…The division of the number of tendons to the fingers is related to the degree of movement of the digits. 23 These muscular characteristics are consistent with the behavior of each species during the hunting of its prey, 24 both in the distances they travel and in the size of the different preys.…”

Influence of Screw-Hole Defect Size on the Biomechanical Properties of Feline Femora in an Ex Vivo Model

“…Conversion to craniocaudal loading eliminated this as supports were now balanced on the flatter caudal surface. 33,35 This methodology has been corroborated by other femoral defect model experiments, where anteroposterior deficits 15 and three-point bending 36,37 were used for biomechanical evaluation. Fourpoint bending is an alternative to minimize shear-however, boundary constraint errors may still result from the short femoral span length.…”

“…32 With feline femoral diaphysis not uniformly tubular, the shear component of three-point bending was accentuated with mediolateral HB during pilot trials. 33,34 Resultant indiscriminate rotations led to sizable variations and was not reflective of pure bending to be evaluated. Conversion to craniocaudal loading eliminated this as supports were now balanced on the flatter caudal surface.…”

Morphometric analysis and three-dimensional computed tomography reconstruction of the long bones of femoral and crural regions in Van cats

“…In addition, these measurements hold an important place in determining morphological variations and taxonomic classifications among different species of the same genus; as well as identifying the differences between sexes [5,23,38]. For this purpose, many studies have been conducted on humans [21,22,42] and animals [2,5,9,10,16,14,29,33,36] that involved obtaining osteometric measurements on the long bones of their pelvic limbs. In our study, the morphometric, volumetric and surface area measurements of the femur, tibia, and fibula of adult Van cats were obtained via CT scans and 3D modeling, in order to identify the differences between the two sexes.…”

“…Various studies have been performed to determine the anatomical and osteometrical properties of the main long bones of the pelvic limbs (femur, tibia, fibula) of different animal species, like mole-rats (Spalax leucodon Nordmann) [34], African giant rats (Cricetomys gambianus Waterhouse) [27], grasscutter rodents (Thryonomys swinderianus, Temminck-1827) [29], guinea pigs (Cavia porcellus) [37], feral pigs (Sus scrofa) [19], martens (Martes fonia) [3], badgers (Meles meles) [32], squirrels (Sciurus vulgaris) [31], hedgehogs hedgehog (Erinaceus europaeus L.) [35], porcupines (Hystrix Cristata) [49], chinchillas (Chinchilla lanigera) [10], lumholtz tree-kangaroo (Dendrolagus lumholtzii) [40], Anatolian bobcats (Lynx lynx) [30], New Zealand rabbits (Oryctolagus cuniculus) [1,16,36], marmosets (Callithrix jacchus) [9], brown bears (Ursus arctos) [13], deers (Hippocamelus bisulcus) [41], sheeps (Ovis aries) [2], gazelles (Gazella subgutturosa) [12], foxes (Vulpes vulpes and Alopex lagopus) [24], dogs (Canis lupus familiaris) [28,43], and domestic cats (Felis catus and Felis domestica) [5,16]. No study was found when the existing literature was searched for long bones of the pelvic limbs of Van cats, however.…”
