This osteoporosis model consists of 3 medially divided lumbar vertebrae with intervertebral discs. For anatomical comparison, the upper section shows healthy bone structure, the middle section osteoporotic bone structure and the lower section advanced osteoporotic bone structure with flattened plates, deformation and decreased bone mass. For detailed anatomical study the vertebrae can be removed from the stand. The osteoporosis model is a great high quality anatomical teaching. Now included with all 3B Scientific Anatomy models is the 3B Smart Anatomy app. This app allows users to register their 3B item to extend the warranty from 3 to 5 years plus free 1 year access to the 3B Smart Anatomy app which includes 23 Anatomy lectures, 117 interactive models and 39 quizzes.
