Our Mission For Patients: Minimally Invasive Bone Harvesting

From Dr. Jim Marino’s initial vision of a minimally invasive procedure to more than 10,000 procedures today, we’re on a mission to improve patient experiences and make autologous bone harvesting your first choice.   

The COREX minimally invasive bone harvester is engineered to help you consistently deliver optimal patient outcomes.

Watch COREX in action

Traditional harvesting techniques and non-autograft substitutes have increased harvest site morbidity and limited fusion potential

Traditional Techniques and Instruments Are Invasive

Traditional harvesting techniques add to harvest site morbidity and pain.

The High Cost and Questionable Efficacy of Autograft Substitutes

Synthetics, allograft and other non-autologous options add costs and offer limited osteoinductive, osteoconductive, and osteogenic properties. 

The Blood Borne Pathogen Potential

Allografts carry the risk of BBP, potentially putting the patient at unnecessary risk.

Precision Engineered: The COREX Solution

From the beginning, COREX was conceived and engineered specifically to harvest cancellous bone graft using a minimally invasive technique.

Frequently Asked Questions

Can I Harvest Enough Autologous Bone Graft for the Procedure?

In most cases, and depending on your patient, you get enough cancellous bone for 1 & 2 Level fusions.

What if I don’t want to subject my patients to secondary surgical site?

There is clinical evidence suggesting using COREX MIS Bone Harvester significantly reduces if not mitigates the typical secondary surgery site pain associated with a traditional approach.

I use bone from the lamina and facets which I then morselize.

While using bone has its benefits, using the COREX system will allow you to harvest an unlimited amount of fresh autologous bone with a “multi-pass” capability hence reducing the need for bone filler additives and provided fresh malleable osteogenic, conductive, and inductive autograft (gold standard).

I don’t want to add additional costs to my procedures.

The cost of COREX is negligible compared to 3ccs of any bone alternative and has 3 reimbursable CPT codes.

I have been using BMP since fellowship, and don’t want to change.

Understood. However, would reducing cost and assuring proper fusion with fresh autologous bone be worth considering if it were possible?

I used another system and it was cumbersome!

COREX is an all in one MIS system that harvests, captures and delivers autologous bone with one simple mechanism.

I have used another system and I find that I cannot harvest enough bone for my surgical needs. Will this do the same?

The COREX all in one system is engineered to be able to make multiple passes to collect as much bone as need using different angled trajectories form the same collection site.

Will this slow me down? I have used other systems and the sterilization time and configuration slows down the surgery.

The COREX system is an all in one MIS design does not need sterilization or assembly. It comes out of the single use box ready to use.

When it comes to materials, spine instrumentation is one of our biggest expenses. Will this increase expenditure?

Using the COREX system will reduce if not alleviate the need for bone biologic alternatives. In addition, there are three reimbursable CPT codes.

How long does it take to harvest with COREX?

When used appropriately, it’s 5 – 7 minutes.

How long does it take to learn to use COREX?

COREX has a low learning curve. Many surgeons have successful outcome from the first use. it’s reasonable to achieve proficiency within 3 – 5 minutes.
