Natural-size elbow joint model BIX-A1026 — elbow rotation and forearm movement on a plastic seat, 17 x 14.5 x 24 cm.
...Short answer: BIX-A1026 is a natural-size elbow joint model, 17 x 14.5 x 24 cm, mounted on a plastic seat. The product page states it shows the rotation of the elbow joint and the curvature and rotation of the forearm bones — the page's wording says "tibia", which is evidently a translation slip for the forearm. It displays US $14.74, the same figure as the knee listing, so confirm the price per model.
Key takeaways
| Item | Published detail |
|---|---|
| Model | BIX-A1026 |
| Product name on page | Natural Elbow Joint Model — Elbow & Radial Rotation Anatomy |
| Category path | Medical Series → Skeleton Series → Joint Models |
| Scale | Natural size |
| Dimensions | 17 x 14.5 x 24 cm |
| Mounting | Placed on a plastic seat |
| Motion shown | Rotation of the elbow joint; curvature and rotation of the forearm bones |
| Displayed price | US $14.74 — same as the knee listing; confirm per model |
| Misconception | What the model lets you show | What it cannot show |
|---|---|---|
| "The elbow only flexes and extends" | Forearm rotation happening at the same joint complex | Membrane tension between the two bones |
| "Pronation happens at the wrist" | The forearm bones rotating as a unit | Individual muscle action |
| "Any elbow injury limits the same motion" | Which plane of motion is lost by pointing at the articulation | Pain behaviour or clinical tests |
| "Landmarks are hard to find" | Palpable-scale anatomy at 1:1 | Soft-tissue swelling |
The elbow is a joint where the student's hand has to learn a shape. Radiographic interpretation depends on knowing the normal relationships well enough to notice a subtle displacement, and 2026 work in the Journal of Hand Surgery Asian-Pacific Volume examined whether contralateral elbow radiography improves diagnostic accuracy in paediatric elbow injury — a study that only makes sense if the reader already holds a three-dimensional model of the joint in mind [1]. The standard anatomical reference for the region describes the elbow as a compound joint with three articulations and a shared capsule, which is precisely the structure a single-axis mental model misses [2]. A Sports Biomechanics study on wrist height at lead-foot contact and its effect on shoulder and elbow moments shows the same joint behaving as part of a kinetic chain [3].
Use the model to establish the shape, then move to images and then to the patient. The order matters: image first, model never, is how misconceptions harden.
| Step | Activity | Time |
|---|---|---|
| 1. Landmark | Find the three articulations by touch on the model before naming them. | 5 min |
| 2. Motion | Demonstrate flexion, extension and forearm rotation; a partner names each as it happens. | 8 min |
| 3. Transfer | Repeat the same three motions on a partner's arm, with consent, and compare feel. | 7 min |
| 4. Test | Instructor moves the model behind a screen; students name the motion from the sound and description only. | 5 min |
| Not stated on the page | Why it matters |
|---|---|
| Confirmed unit price | The displayed figure matches another SKU; confirm before ordering. |
| Material | Affects durability and cleaning. |
| Ligament representation | Decides whether you can teach valgus and varus restraint. |
| Weight | Needed for freight on class sets. |
| Range-of-motion stops | Natural limits protect the model when students push. |

Q1. What is BIX-A1026?
A natural-size elbow joint model, 17 x 14.5 x 24 cm on a plastic seat, showing elbow rotation and forearm movement.
Q2. Is it life-size?
It is described as natural size; the published dimensions are 17 x 14.5 x 24 cm.
Q3. What motion does it demonstrate?
Rotation of the elbow joint and the curvature and rotation of the forearm bones.
Q4. Why does the page mention the tibia?
That is a translation error in the product text; the model is an elbow, and the bone referred to is a forearm bone.
Q5. Is a price published?
The page displays US $14.74, but the same figure appears on the knee model page. Confirm the price for BIX-A1026 specifically.
Q6. How do I order?
Email cprmodel@adaanatomy.com with model BIX-A1026, quantity and delivery city.
Write to cprmodel@adaanatomy.com for the BIX-A1026 material specification, weight and confirmed price. If you also teach the shoulder or wrist, mention it — the same joint series shares a base design, which keeps a skills bench tidy.
