Addressing Problems In Total Shoulder Replacement Surgery

The problems encountered with current total shoulder replacement models are based upon the fact that the glenoid sits on top of the bony surface.

So when the humerus goes up and down, rotates, and slides back-and-forth, it rocks the glenoid loose potentially because it’s sitting on the surface.


Inset Glenoid

This problem is solved with an inset glenoid because the glenoid doesn’t sit on the surface. The implant sits partially within the bone like a manhole cover surrounded by a peripheral rim of strong sclerotic bone.

Another advantage of this inset glenoid fixation is that because there’s such a strong circumferential rim of cortical bone, you don’t need much backside fixation and you can place the implant in deficient bone without much bony support.

New scientific data presented in the literature in the Journal of Shoulder and Elbow Surgery shows that the inset glenoid fixation technique increases the strength of fixation by up to 40 times.

Familiar, Proven Design Improved With fewer Surgical Steps

  • Unique countersunk head design allows the head to rest securely on the cut surface, eliminating any visible gap on x-ray1.
  • Robust and proven humeral system design, implanted with simplified technique and fewer instruments.
  • Humeral stem cleared for use with or without bone cement.
  • Humeral stems manufactured from cobalt chrome alloy in five diameters 6, 8, 10, 12 and 14mm, each 130mm in length.
  • Humeral heads manufactured from cobalt chrome alloy are offset 3mm and are available in three diameters 40, 46 and 52 providing 10 humeral head sizes.

Fewer Instruments

Our surgical team looked at all instrumentation, and we’ve simplified the process by removing unnecessary steps that complicate shoulder surgery.

All instrumentation required to implant the Shoulder Innovations Total Shoulder System comes in ONE instrument case, for less cost and inventory administration.


Long-Term Results

Fewer Surgical Steps

Less Administration

 


Design Rationale

Shoulder Innovations Total Shoulder Replacement System is the next generation of a safe, effective, glenoid implant, to reconstruct deficient bone when today’s implants simply won’t work.

Surgical Technique

The inset technique includes placing the glenoid implant down into a shallow pocket below the articular surface with a strong, circumferential cortical bone periphery. Supplemental fixation is also provided utilizing a scalloped central post, peripheral pegs, and peripheral cement channels.
