Actipore Material Introduction  

Within the orthopaedic field, one of the greatest challenges has been the permanent fixation of metal implants to bone. Various methods, such as screws, glue, cement and porous surfaces are used today to remedy this problem. However, none of these methods offer a completely successful solution. This unsolved challenge often leads to costly surgical revisions and retraining graduates.

Biorthex's patented Actipore technology platform introduces a leading edge solution to this age-old problem.

Actipore is a porous nitinol, which is an intermetallic TiNi molecule with excellent biological and biomechanical compatibility.

Nitinol material in its solid form, has been known and approved by the FDA and used clinically worldwide for over a decade. Nitinol is known for its biocompatibility and its shape memory properties.

Biorthex, with its worldwide patent protection on porous nitinol, is the first and only company to introduce nitinol in a porous form.

Actipore, as seen in the above picture, is a unique ultra porous, biologically and biomechanically compatible Nitinol material, having a porous structure made of interconnected passageways which permit bone cell penetration, long term bone cell survival and integration throughout the devices. 

The Actipore range of interbody devices, as a consequence of the isotropic interconnected porous structure and the capillary wicking forces, actively draw essential fluids and nutrients into the implant allowing for strong, rapid growth of newly forming bone cells throughout its ultra porous scaffold.

As a result, no additional bone graft material is required, thus eliminating the risk of associated graft site morbidity.

A low modulus of elasticity, closely resembling that of cancellous bone, as well as MRI and CT scan compatibility, make the Actipore devices a welcome and advantageous addition to physician spinal device selection.

Actipore devices have an approximate porosity of 65% and an ideal average pore size of 215 microns, resulting in immediate perfusion and strong rapid growth of newly forming bone throughout its ultra porous scaffold. Although porous, Actipore has superior compressive strength in comparison to bone, while sharing a similar modulus of elasticity, therefore minimizing the risk of stress shielding and compromised device performance.
