## What Cadara Foot is

Cadara Foot is a cadaver emulator for minimally invasive foot surgery training. It is a four-layer
physical model built to behave like a patient under instruments:

- **Radiopaque skeleton** with real deformities built in. Correct them and the foot transforms, just
  like a patient's. Every burr pass and osteotomy shows up under X-ray and fluoroscopy.
- **Translucent membrane** encasing the skeleton, the surgical window that lets you watch your
  instruments work. You cut your own portal into it.
- **Proprietary soft-tissue gel matrix** that fills the membrane and forms authentic bone paste
  under reduction.
- **Lifelike dermis** with palpable landmarks, over tendon-mimicking joint sleeves. Palpate your
  landmarks, make the stab incision, trust your hands.

The material is not silicone and not rubber. It is a proprietary material system, specialty
formulated in-house by Dr. Ahn and Dr. Au through hundreds of iterations. It cuts with honest
resistance, forms authentic bone paste under reduction, and reads on X-ray like a patient. That
formula is the product. Everything else is anatomy.

Non-biological and non-toxic. No lab, no gloves, no refrigeration, no disposal protocols.
U.S. patent pending.

## Who it is for

Podiatric surgeons, foot and ankle surgeons, orthopedic surgeons, and surgical residents building
minimally invasive surgery skills. Also device companies and distributors who train surgeons on
their own fixation systems without the cost and complexity of cadaver labs.

## Key facts

- **Procedures per foot:** 12+, including bunion with Akin, Tailor's bunion, exostectomy, lesser
  digit and lesser metatarsal procedures, and plantar fasciotomy with heel-spur resection. Each
  surgical site is single-use, like real surgery.
- **Finishes:** translucent (watch the instrument work) or skin color (earn it by feel).
- **Pricing:** Single $499. Pair $949.
- **Shipping:** ships in 10–14 days. Checkout completes on innohealthsystems.com.
- **Imaging:** radiopaque, fluoro-ready.
- **Not a replacement for cadaver labs.** It is a bridge between labs and live patients. Labs teach
  technique. Cadara Foot builds the sensations through repetition.

## Frequently asked questions

**Do I need a lab, gloves, or any special setup?**
No. Cadara Foot is non-biological and non-toxic. Practice bare-handed at your kitchen table, in your
office, or between clinic patients. No refrigeration, no disposal protocols, no paperwork.

**How close is it to a real cadaver?**
Cadara Foot is a cadaver emulator: radiopaque bone, joint capsules, soft-tissue gel, and a lifelike
dermis layered to behave like a human specimen under your instruments. Every layer is a proprietary
material formulated in-house by Dr. TJ Ahn and Dr. CJ Au through hundreds of iterations. For a full
mock-up it simulates cadaver work, and in some ways it is closer to a live patient: consistent
anatomy, no tissue degradation, and it is ready whenever you are.

**Is Cadara Foot reusable?**
Each surgical site is designed for single use, just like in real surgery. One foot supports 12+
procedures across your MIS caseload: bunion with Akin, Tailor's bunion, exostectomy, lesser digit
and lesser metatarsal procedures, and plantar fasciotomy with heel-spur resection.

**Does it feel like real tissue?**
Yes. Cadara Foot ships with real deformities and transforms into a corrected foot as you perform the
procedures, just like a human foot. Skin that reads like skin, tendon-mimicking joint sleeves, and a
proprietary gel that forms authentic bone paste under reduction.

**Can I use X-ray or fluoroscopy?**
Yes. Cadara Foot is radiopaque. It shows up clearly under X-ray and fluoroscopy for complete
real-patient simulation.

**Is this a replacement for cadaver labs?**
No. It is a bridge between labs and live patients. Cadaver labs teach you surgical techniques.
Cadara Foot builds the sensations required for MIS through repetition.

**How much does shipping cost?**
Shipping is calculated based on your location and the items in your order. You will always know the
shipping price before you purchase.

## Why it exists

A cadaver lab is one day. Mastery is daily. A cadaver lab teaches technique, then ends, and the
learning stops the day the lab ends. Specimens require booking months out, cold chain, consent
forms, and disposal protocols.

Cadara Foot exists so a surgeon can get MIS repetitions on their own schedule: over lunch, between
patients, or at home. Your lab is wherever you are.

## Who built it

- **Dr. TJ Ahn, DPM**: CEO and co-founder. Board-certified podiatric surgeon. 1,500+ MIS bone cases
  of his own, 2,000+ surgeons trained across 58 cadaver labs he hosted.
- **Dr. CJ Au**: COO and co-founder. MIT- and Harvard-trained engineer, 12 U.S. patents, Red Dot
  Award winner.

They co-formulated the material through hundreds of iterations over 14 months of R&D. Twenty-eight
bones were printed, corrected, and articulated by hand, joint capsules wrapped one at a time, and
alignment checked against real anatomy from 1,500 cases. The skeleton had to deform like bone, cut
like bone, and show up on fluoro like bone. No off-the-shelf part existed, so none were used.

Cadara Foot launched in May 2026: the first radiopaque, skin-wrapped MIS training model with
single-use surgical sites.

## For device companies and distributors

Surgeons adopt what they are confident in. A cadaver lab ends and the learning stops with it, while
a single cadaver leg costs more than twice a Cadara Foot unit.

With Cadara Foot, every sales rep carries a training lab: a high-fidelity foot model instead of an
expensive cadaver lab you had to book months out. Surgeons practice your fixation system on their
own schedule. More surgeons confident on your system means more cases performed on your implants.
