Innovasis Spine Symposium 2017

Innovasis Spine Symposium 2017

Innovasis just finished their 6th annual Spine Symposium held in Deer Valley.  This year's Symposium focused on spine care from childhood to old age.  Deformity discussions included; challenges in the treatments of deformities in the growing child, transitioning from adolescent to adult deformity and when to operate on the adolescent or wait to adulthood.  Also, included in the deformity discussions were how to correct adult degenerative scoliosis.  Other topics included were: Spinal balance, correction of the rotational deformity, adult degen, complications, cervical arthroplasty and many, many case discussions.

We want to thank our amazing faculty and everyone that presented a case or was involved in some capacity, a special thanks goes out to our chairman Dr. Alan Moskowitz, MD from the Kansas Orthopedic Center, for putting together the wonderful agenda and speaker base.  Here is some of the feedback we are hearing about this meeting:

  • "Great meeting. Excellent venue."
  • "Excellent meeting with great growth each year."
  • "Experience was great!"
  • "Great meeting. Good for surgeon education and fun for the family."
  • "Really first class meeting and hotel."

SA ALIF - Ax™

SA ALIF - Ax™

Innovasis is getting excited to launch our new SA ALIF.  We will be the first company to launch a Stand-Alone ALIF with Invibio® PEEK-OPTIMA® HA Enhanced.  The implant will be available at the end of Q1*.  Here are some facts about our new SA ALIF:

The Innovasis Ax Stand-Alone ALIF System is an intervertebral body fusion device for use in patients with degenerative disc disease (DDD) at one or two contiguous levels of the lumbar spine (L2-S1). These implants are used to facilitate fusion in the lumbar spine and are placed via an anterior (ALIF) approach.

The implant is radiolucent allowing straightforward assessment of the fusion process, while two tantalum spheres enable implant visualization during the surgical procedure.  The HA PEEK body is joined to a 6 Al 4V ELI titanium faceplate that interfaces with the inserter and holds the fixation screws.

The device is offered in an array of sizes:  three footprints, six height options and four lordosis options.   The implants have a tapered leading edge which aids in implant insertion due to limited anatomical space. They feature a slightly convex profile to match the anatomy and anti-migration surface to ensure implant stability during the fusion process. The large graft cavity provides increased volume for autograft loading.

Does PEEK/HA Enhance Bone Formation Compared to PEEK in a Sheep Cervical Fusion Model?

Does PEEK/HA Enhance Bone Formation Compared to PEEK in a Sheep Cervical Fusion Model?

  • Polyetheretherketone (PEEK) has a wide range of clinical applications but does not directly bond to bone. Bulk incorporation of osteoconductive materials including hydroxyapatite (HA) into the PEEK matrix is a potential solution to address the formation of a fibrous tissue layer between PEEK and bone and has not been tested.
  • Using in vivo ovine animal models, we asked: (1) Does PEEK-HA improve cortical and cancellous bone ongrowth compared with PEEK? (2) Does PEEK-HA improve bone ongrowth and fusion outcome in a more challenging functional ovine cervical fusion model?
  • The in vivo responses of PEEK-HA Enhanced and PEEK-OPTIMA® Natural were evaluated for bone ongrowth in the form of dowels implanted in the cancellous and cortical bone of adult sheep and examined at 4 and 12 weeks as well as interbody cervical fusion at 6, 12, and 26 weeks. The bone-implant interface was evaluated with radiographic and histologic endpoints for a qualitative assessment of direct bone contact of an intervening fibrous tissue later. Gamma-irradiated cortical allograft cages were evaluated as well.
  • Incorporating HA into the PEEK matrix resulted in more direct bone apposition as opposed to the fibrous tissue interface with PEEK alone in the bone ongrowth as well as interbody cervical fusions. No adverse reactions were found at the implant–bone interface for either material. Radiography and histology revealed resorption and fracture of the allograft devices in vivo.
  • Incorporating HA into PEEK provides a more favorable environment than PEEK alone for bone ongrowth. Cervical fusion was improved with PEEK-HA compared with PEEK alone as well as allograft bone interbody devices.

Px HA™ Now available!

Px HA™ Now available!

 

 
Innovasis is excited to announce that its newest product is now available to use..... the Px HA interbody device.

The Px HA system is for Posterior Lumbar Interbody Fusion (PLIF).  The implants are made from Invibio® PEEK-OPTIMA® HA Enhanced, which is integrated with an osteoconductive hydroxyapatite (HA).  

The implant is radiolucent allowing straightforward assessment of the fusion process, while three tantalum spheres enable implant visualization during the surgical procedure.  

The device is available in multiple size options to facilitate a more precise anatomical fit.  It has a tapered leading edge which aids in implant insertion due to limited anatomical space, and features a slightly convex profile to match the anatomy and anti-migration teeth to ensure implant
stability during the fusion process. The large graft cavity provides increased volume for autograft loading.

The system features a unique inserter design which helps prevent cross threading and minimizes implant breakage.

Invibio® PEEK-OPTIMA® HA Enhanced provides the accepted high performance characteristics of PEEK-OPTIMA Natural, the leading spinal interbody device material, plus Hydroxyapatite (HA) to enhance bone apposition.  This combination is a potential solution for medical applications where early bone on-growth is required, such as spinal interbody fusion.

Invibio® PEEK-OPTIMA® HA Enhanced polymer is the latest development in high performance materials for interbody fusion devices.  Hydroxyapatite (HA), a well-known osteoconductive material that enhances bone apposition, is fully integrated, not coated, into the PEEK-OPTIMA matrix, making it available on all surfaces of a finished device.  Building on PEEK-OPTIMA, the leading PEEK-based biomaterial with over 15 years of clinical history, the benefits include, modulus similar to bone, reduced stress shielding and artifact-free imaging.
