BIX-A3572 Guide: Teaching Lumbar Disc Degeneration as a Sequence, Not a Snapshot

Short answer: The BIX-A3572 is a four-stage pathological lumbar spine comparison model that shows the progression of lumbar pathology across four comparative stages. It is built for two audiences at once: orthopedic and physiotherapy teaching, where the sequence of degeneration has to be understood, and patient education, where a patient needs to see why their back hurts now and what the next stage looks like.

Key takeaways

• Four stages displayed together, so the pathology is taught as progression rather than one static specimen
• Comparison format: each stage sits beside the others on a single model
• Suits orthopedic teaching, physiotherapy training and patient education
• Explains disc degeneration in a way a diagram of a single vertebra cannot
• ISO and CE certified per the product page

What the model shows

Why the sequence matters more than the stage

Low back pain is not a rare event that happens to a few patients. A systematic review of the global prevalence of low back pain found it to be extremely common across populations worldwide [1], and the Lancet review of low back pain documents years lived with disability increasing substantially between 1990 and 2015, largely through population growth and ageing [2]. Degenerative disc and facet joint disease of the lumbar spine is one of the most frequent causes of disability in ageing populations [3].

What the evidence also shows is that the imaging finding and the pain do not map onto each other neatly. That is why clinical guidelines concentrate on function and non-invasive management rather than on the picture alone; the American College of Physicians guideline for acute, subacute and chronic low back pain recommends non-invasive treatment as the first approach [4]. A model that displays four stages is therefore not a diagnostic tool — it is an explanatory one.

Used properly, the A3572 does two jobs. For students, it makes the natural history of disc degeneration visible so that the clinical course makes sense. For patients, it transfers an abstract diagnosis into something they can point at, which is one of the more practical uses of any anatomical model.

Running a session with the A3572

• Work the sequence. Start at the least affected stage and move through. Ask what changes between each step — disc height, endplate, facet involvement.
• Separate image from symptom. Ask students to state, for each stage, what symptoms would be expected and why those symptoms are not guaranteed.
• Link to management. Follow each stage with the conservative measures that would be tried first, using the guideline-based approach.
• Use it with patients. In a consultation, point to the relevant stage, then explain what the plan will and will not change.
• Build a bad-news script. Ask students to explain stage four to a patient in under two minutes without jargon. This is the exercise that most reliably exposes gaps.

What to check before you order

• Stage definitions. Ask the supplier for the exact description of each of the four stages so the model matches your curriculum's terminology.
• Mounting. Confirm the base or stand supplied, since a comparison model is normally displayed permanently.
• Language of labels. Request the label language, especially if the model will be used in patient consultations.
• Price. This page does not publish a price; the model is quoted on request and depends on volume.

FAQ

Q1. What is the BIX-A3572?
It is a four-stage pathological lumbar spine comparison model that displays the progression of lumbar pathology for teaching and patient education.

Q2. How many stages does it show?
Four comparative stages, presented together on one model.

Q3. What is it used to teach?
Disc degeneration and lumbar pathology progression, in orthopedic and physiotherapy teaching and in patient education.

Q4. Can it be used directly with patients?
Yes. Its comparison format is designed to help patients see the progression of their condition.

Q5. Is the model certified?
The product page states ISO and CE certification.

Q6. How do I get a price or the stage descriptions?
Email chinoncpr@adaanatomy.com with the model (BIX-A3572), the quantity you are considering and your destination port; our export team will reply with pricing, lead time and the stage details.

Email chinoncpr@adaanatomy.com for the BIX-A3572 price list and shipping details. If your programme covers the rest of the spine, the same spine range includes cervical, thoracic and full vertebral column models, so a spine-teaching set can be specified in one order.
