Abstract

Lizards are historically recognized for the ability to voluntarily amputate and regenerate their tails. However, while caudal autotomy has been extensively studied, other types of amputations in lizards remain scientifically underestimated. The present study aimed to assess the extent of knowledge about different types of amputations in lizards and, specifically, to describe anatomically the patterns of limb amputations in Neotropical lizards. We first carried out a systematic bibliographic research regarding the subject, in four academic databases. Moreover, we anatomically described the amputations of seven specimens housed in scientific collections, using external morphological analysis and radiographic techniques. The bibliographic survey revealed that most amputations are related to caudal injuries (67%), while limb amputations accounted for only 24% of the records. Most records mentioned amputations in pelvic limbs (68%), the majority of amputations were provoked by medical-therapeutic procedures (96%), and the main method applied to analyze these lesions were microscopy techniques (80%). Most of the injuries evaluated in museum specimens were also in the hind limbs (86%), mainly involving ruptures in the tibia and fibula and in the femorotibial joint. We also described in detail two rare cases of regeneration of tail-shaped appendages in amputated hind limbs for two species of Neotropical lizards. Our findings revealed that natural amputations in lizard limbs constitute a promising knowledge field for future research, and reinforced the importance of using different assessment methods to investigate body injuries. Thus, we have contributed to the understanding of the causes and consequences of the limb amputation process in lizards.

放射摄影显示的蜥蜴截肢情况
蜥蜴具有主动截尾和再生的能力,这一点历来为人们所公认。然而,尽管尾部自体切除术已被广泛研究,但科学界对蜥蜴其他类型的截肢仍然估计不足。本研究旨在评估对蜥蜴不同类型截肢的了解程度,特别是描述新热带蜥蜴肢体截肢的解剖模式。我们首先在四个学术数据库中对这一主题进行了系统的文献研究。此外,我们还利用外部形态分析和放射学技术,对科学收藏的七件标本的断肢进行了解剖学描述。文献调查显示,大多数截肢都与尾部损伤有关(67%),而肢体截肢仅占记录的 24%。大多数记录提到了骨盆肢体的截肢(68%),大多数截肢是由医学治疗程序引起的(96%),分析这些病变的主要方法是显微镜技术(80%)。在博物馆标本中评估的大多数损伤也发生在后肢(86%),主要涉及胫骨、腓骨和股胫关节的断裂。我们还详细描述了两种新热带蜥蜴截肢后肢尾状附肢再生的罕见案例。我们的研究结果表明,蜥蜴肢体的自然截肢是未来研究的一个很有前景的知识领域,同时也加强了使用不同评估方法调查身体损伤的重要性。因此,我们为了解蜥蜴断肢过程的原因和后果做出了贡献。

期刊介绍: The journal publishes original research papers, reviews and method papers. While reviews should be designed as comparative surveys, summarizing the current knowledge from an evolutionary perspective, method papers should present new approaches or reviews on methods used in animal morphology. The research papers should be based on morphological investigation of invertebrates and vertebrates at the macroscopic, microscopic and ultrastructural level, including embryological studies.
