Simple to use synthetic resorbable material designed to promote regeneration of bone in osseous defects

genex is a catalyst for bone healing. It complements the body’s natural healing processes, enabling the optimal remodeling of bone architecture to that of native trabecular bone. In 12 months, genex is completely absorbed and remodeled while leaving no foreign artifacts after resorbtion.1,2

  • Cleared for bony voids and defects that are not intrinsic to stability of the bony structure.

Biphasic composite with purity and balance

genex is specifically formulated to provide the desired balance of scaffold strength and persistence in the body with optimum handling, workability and remodeling.

Our proprietary recrystallization and purification methods remove impurities such as:6
✘ No inflammatory pyrophosphates
✘ No slow and non-absorbing compounds such as hydroxyapatite

Completely absorbed to leave no trace

genex is a precisely balanced β-tricalcium phosphate/calcium sulfate hemihydrate compound with distinct design properties:

  • Contains no hydroxyapatite (HA)
  • Negatively charged surface chemistry
  • Compressive strength similar to trabecular bone3-5

genex provides a powerful osteoconductive scaffold for accelerated bone restoration and helps to hinder soft tissue ingrowth:

  • Enhances osteogenic response10
  • Completely absorbed within 12 months1
  • Several studies have concluded healthy bone is restored in a clinically relevant timeframe7-9

Completely absorbed within 12 months1,2

genex contains no hydroxyapatite. HA can only be absorbed at 1–2% per year12

Unrivaled flexibility for delivery and application

With one of the most comprehensive bone graft substitute systems at your fingertips, genex equips you with everything you need to adapt to the wide ranging and sometimes unpredictable demands of trauma surgery.

From difficult-to-reach sites or minimally invasive procedures, genex enables you to inject, mold or prepare beads according to your chosen technique.

The genex closed-mixing system maximizes efficiency and provides the assurances of:

  • fully supported aseptic technique
  • shorter preparation time and extended working time
  • reduced waste

genex has a working time of 3 to 5 minutes and is drillable after 15 minutes.

Frequently asked questions
What is genex indicated for?

genex offers successful long-term outcomes across a range of surgical applications in the upper and lower extremities, including: tibial plateau fractures, core decompressions, long-bone non-unions, critical bone defects, humeral head fractures, acetabular voids and revisions.

genex is designed to promote regeneration of bone in osseous defects.  It is absorbed and replaced with bone during the healing process.

genex is indicated only for bony voids or defects/gaps that are not intrinsic to the stability of the bony structure.

genex is indicated to be gently packed into voids or defects of the skeletal system (i.e. long bones, extremities, posterolateral spine and pelvis).

genex resultant paste can be injected, digitally packed into the bone void to cure in situ or molded into solid implants that are to be gently packed into the defect. The bony defects or cavities may be surgically created or the result of traumatic injury.

What is genex contraindicated for?

Filling of defects which are intrinsic to the stability of the bony structure; severe vascular or neurological disease; uncontrolled diabetes; severe degenerative bone disease; pregnancy; uncooperative patient who can’t or won’t follow post-operative instructions including individuals who abuse drugs or alcohol; hypercalcaemia; use in the cranium; use in vertebral compression fractures.

How long does genex take to absorb in bone?

genex is completely absorbed within 12 months.

Is genex drillable?

Yes. 15 minutes after the addition of the mixing solution.

How long do I have to inject genex?

genex is injectable for up to 3 minutes from the addition of the mixing solution.

How long do I have to manually implant genex?

genex is moldable and implantable from minute 3 to 5 after the addition of the mixing solution.

Who is using genex?

genex is used in 15,000 cases every year, in over 30 countries –  including the USA, across a wide range of different indications.
