Ensuring their well-being involves a nuanced understanding of their unique anatomy, physiology, common health issues, diagnostic approaches, and surgical interventions. This review aims to provide a detailed exploration of the current practices, challenges, and advancements in the medicine and surgery of tortoises and turtles. Introduction Turtles and tortoises are ancient reptiles with a fossil record dating back over 220 million years. Their diverse habitats, ranging from terrestrial deserts to freshwater rivers and marine environments, influence their physiology and susceptibility to various diseases. Veterinarians specializing in reptile medicine must navigate their distinctive anatomical features, such as their keratinized shells, specialized respiratory structures, and unique immune responses. Anatomical and Physiological Considerations Understanding turtle and tortoise anatomy is fundamental to diagnosing and treating health issues effectively. Shell Structure and Function The shell comprises the dorsal carapace and ventral plastron, formed by fused ribs, vertebrae, and osteoderms covered by keratinized scutes. The shell serves multiple functions: - Protection against predators and environmental hazards. - Mineral reservoir, especially for calcium regulation. - Affects respiratory mechanics due to its rigidity. However, the shell's rigidity can complicate surgical procedures and impact respiratory function in diseased states. Respiratory System Unlike mammals, turtles and tortoises lack a diaphragm. They respire via movement of the limb and neck muscles to change the volume of the pulmonary cavity. Their lungs are located within the thoracic cavity, adjacent to the shell, and are relatively large relative to their body size. Circulatory and Immune System Their cardiovascular system includes a three-chambered heart with a septum that allows some mixing of oxygenated and deoxygenated blood, affecting their response to systemic infections and anesthesia. The immune system features lymphoid tissues associated with the shell, and their immune response can be slower or less robust compared to mammals, influencing disease progression and treatment strategies.
