The Four Stage Vertebrae Set is an anatomical model featuring 4 pairs of life-size lumbar vertebrae in 3 stages of degeneration. Shown are a normal pair of lumbar vertebrae, a pair with a bulging herniated disc, a vertebrae set with bone and disc degeneration, and finally, advanced osteoporosis with serious bone compression and bone spurs. The Four Stage Vertebrae models do not dissect but can be removed for individual inspection and study, making this an ideal addition to medical classrooms or offices. The model is accompanied by an informative key card, and is mounted on a sturdy plastic base.
