Abstract
A total number of 61 0 forelimbs and 610 hindlimbs of donkey species were collected from different surgical rooms of veterinary hospitals. These limbs belong donkeys above 3 years old and of both sex. All the collected limbs were examined by naked eye and palpation to select any radiographically detectable surgical abnormalities. According to this examination, a total number of 75 forelimbs and 37 hindlimbs were isolated and radiographed in variable projections. Additional radiographs of 14 forelimbs and 6 hindlimbs were obtained from the radiographic file of Faculty of Vet. Med. Assuit University. Anumber of apparently normal 5 forelimbs and 5 hindlimbs were also imaged. After imaging, bones are macerated and dissected from all the surrounding soft tissues. Measurement of normal radiographic geometric dimensions’ was . carried out for bones of the intended region. Results of measurement illustrates that, in general bones of the forelimbs have a more radiographic geometric dimensions than those of the hindlimbs. The nutrient foramen is located at a relatively higher levelin MT III than MC Ill. Normal radiographic anatomy of donkeys is found greatly resemble to that of horses except that there is no evidence for circumscribed opacity superimposed over the proximal aspect of the proximal phalanx, which represent area of ergot in horses. Moreover, unlike horses, the dorsal surface of P III of the forelimbs in donkeys appeared slightly concave on lateromedial view.
After examination of 610 forelimbs and 610 hindlimbs of donkeys’ which excluded from work and presented to veterinary hospitals for condemnation, a total number of 89 forelimbs and 43 hindlimbs suspected to have radiographic abnormalities in the region below carpus and tarsus are examined by X-ray. An additional apparently normal 5 forelimbs and 5 hindlimbs subjected also to radiographic imaging. In presence of bone specimens of these limbs, the radiographs are interpreted and the radiographic geometric dimensions of the bones are obtained, also the normal radiographic anatomy of the region, in addition to the radiographic picture of the surgical affections. The prevalent radiographically detected surgical affections include, bone fractures, periostitis and subsequent new bone formation, soft tissue mineralization, VNS, SCL, DJD, sesamoiditis, joint luxation, side bone, hoof overgrowth, and pedal osteitis complex. The study justifies the important role of X-ray in diagnosis of surgical affections of the soft and hard tissues distal to the carpus and tarsus in donkeys.
