Radiological investigations of the hedgehog (Erinaceus concolor) appendicular skeleton.
The normal radiographic anatomy of the healthy hedgehog can help to identify anatomic features unique to the hedgehog while comparing it with other small mammals, such as the dog and cat. Radiographic examination is a method that can play an important role in the diagnosis of a wide variety of skeletal diseases. Seven (2 males, 5 females) free-living hedgehogs (Erinaceus concolor) from the Urmia region of Iran were selected for this study. Lateral and craniocaudal radiographs from the front and hind limbs were obtained. The radiographs from these hedgehogs were compared with the normal canine and feline skeletal radiographic anatomy. On the forelimb radiographs, the clavicle was observed as a complete bone connected to the scapula and manubrium. There are three and five carpal bones in the proximal and distal rows, respectively, as in the dog and cat. The pelvis has a larger obturator foramen when compared with the dog and cat. In the lateral view, the pubis and ischium are relatively larger than in the dog and cat and have a more ventral position. The tarsal bones are similar to those of the dog and cat. The number of phalanges and sesamoid bones in the forelimb and hindlimb are likewise similar to those found in the dog and cat.
