在巴西南部，潘帕生物群占主导地位，在道路和高速公路的边缘经常发现死亡的九带螳螂受伤甚至死亡，这是导致野生动物康复中心接收的标本数量增加的原因之一。在野生动物医学中，骨学研究有限，需要正常的骨骼形态信息来进行放射学识别。这项工作的目的是介绍Dasypus novemcinctus骨盆四肢骨骼的形态，指出它们的地形特征以及如何在放射图像中看到它们。研究对象为12具不同年龄段的九条带标本标本的骨盆。身体接受了放射学检查，使用了数字处理和小动物临床常规的实用计划。在每一张X光片上，使用传统的解剖学技术进行个体骨科准备。考虑到解剖学对研究的重要性，对骨骼进行了摄影记录。骨盆肢体的所有骨成分都表现出有利于物种生活方式和习性的特征，抑制了进化的形态可塑性。由于某些关节的特殊解剖特征和有限的活动度，不能像狗或猫那样进行定位，因此一些骨事故无法通过放射图像清楚地记录下来。存在鼻窦，巨大的第三大转子，结构良好的腿，胫骨和腓骨的大小和厚度相似，脚上有复杂的籽骨成分，表明在使用前肢挖掘时将体重转移到骨盆肢体的专业性。这项研究提供了一个放射成像方案，包括从在康复中心工作的野生动物兽医的实际执行中寻找合适的位置。
At South Brazil, where the Pampa biome is predominant, dead nine-banded armadillo is frequentely found injuried or even dead at margins of roads and highways what has contributed to the increasing of number of specimens in admission to wildlife rehabilitation centers. Osteological studies are limited and normal skeleton morphology informations is need to radiographic recognition in wildlife medicine. The objective of this work was to present the morphology of the bones from the pelvic limbs of Dasypus novemcinctus, pointing out their topographical characterization and how their can be seen in radiographic images. Pelvic limbs of twelve dead nine-banded armadillo specimens from different age categories were used. The carcass were underwent radiological examinations using digital processing and practical plans for the clinical routine of small animals. From each radiographed individual osteological preparation was carrying out using conventional anatomical techniques. Photographic records of bones were made considering views of anatomical importance to the study. All bone components of the pelvic limb showed characteristics favorable to the species' lifestyle and habits reforcing evolutive morphoplasticity. Some bone accidents were unable to be clearly recorded through radiographic images because peculiar anatomical characteristics and limited mobility in some joints which not allowed executing positioning as done in the dog or cat. Presence of a sinsacre, a great third trochanter, a well structured leg with tibia and fibula similar in size and thickness and the complex sesamoid elements on feet suggests the specialization in shifting body weight to the pelvic limb while using the forelimbs to dig. The study provided a radiographic protocol includyind suitable positionings from practical execution by wildlife veterinarians that work in rehabilitation centers.
