TRUMATCH® CMF Solutions – PSI/ Materials

Surgeons have a choice of devices produced of two different, biocompatible raw materials:

  • PEEK Optima-LT (polyetheretherketone) or
  • Commercially pure (CP) titanium

PEEK Optima-LT (Polyetheretherketone)

  • Engineered for strength and stability
  • Radiolucent (minimal MRI artifact)
  • Bone-like stiffness and strength
  • Surgeon can determine plate and screw placement during surgery
  • Light weight
  • Autoclavable - withstands repeated sterilization
  • Used with DePuy Synthes cranial and craniofacial fixation systems
  • Implant is 3.0 mm thick (nominal)
  • If modification of PEEK implants are required (e.g. drainage, monitoring devices), they can be performed in the OR with standard instruments

PEEK Mechanical Properties

  Cortical Bone[1] PEEK[1]
Modulus of Elasticity (stiffness) (GPa) 8-24 3.6-4.1
Yield Strength (MPa) 115 113

Notes regarding the use of PEEK Patient Specific Implants:

PEEK Patient Secific Implants require minimal (if any) modification. For minor fit modifications, it is suggested that the surgeon modify the patient bone rather than modifying the PEEK Patient Specific Implant. PEEK Patient Specific Implants can be modified with a high speed burr, if needed. PEEK implants should be modified and rinsed in sterile saline solution away from the implant/surgical site to ensure that the particulate debris does not infiltrate the surgical site after any modifications.

DePuy Synthes standard plates and self-tapping or self-drilling screws should be used to attach the PEEK Patient Specific Implant to the patient. Screw holes, regardless of screw size and type, must be predrilled away from the surgical site.

Titanium (commercially pure, implant grade)

  • Ultra-high strength as compared to cortical bone
  • Radioopaque
  • Autoclavable - withstands repeated sterilization

Titanium implant is 2.5 mm thick (nominal)

Titanium Mechanical Properties

  Cortical Bone[1] Titanium[2]
Modulus of Elasticity (stiffness) (GPa) 8-24 103
Yield Strength (MPa) 115 230

Notes regarding the use of Titanium Patient Specific Implants:

Titanium Patient Specific Implants cannot be modified.  If there are any minor fit modifications required, the surgeon must modify the patient's bone. 

Titanium Patient Specific Implants require the use of DePuy Synthes Low Profile Neuro or MatrixNEURO fixation systems (plates and screws).

The surgeon must preselect the location of the DePuy Synthes plates and machine screw holes during the implant design review process.

The implant will be provided with threaded screw holes.  The Titanium Low Profile Neuro Machine Screws (488.066) are required for attachment of the Low Profile Neuro or MatrixNEURO plates to the titanium implant.
