Summary

Increasing glenosphere contact in reverse shoulder arthroplasty (RSA) enhances implant-bone contact and stability. This improved fixation reduces micromotion and stress, potentially preventing baseplate failure.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Implant Design

Background:

  • Glenoid fixation in reverse shoulder arthroplasty (RSA) is crucial for bony ingrowth and preventing baseplate failure.
  • Inadequate implant-bone contact can lead to eventual baseplate failure.
  • Load sharing through glenosphere contact may enhance baseplate fixation stability.

Purpose of the Study:

  • To quantify the additional implant-bone contact achieved when the glenosphere contacts the glenoid.
  • To evaluate if increased contact area improves baseplate stability via load sharing.
  • To test the hypothesis of increased contact area improving baseplate stability.

Main Methods:

  • 3D modeling of 7 RSA devices using computer-assisted design.
  • Comparison of total implant-bone contact area in two conditions: baseplate-bone contact only vs. baseplate and glenosphere-bone contact.

  • Finite element analysis to compute micromotion and stress for a commercial system.

    • Main Results:

    • All tested RSA devices showed increased contact area when the glenosphere contacted bone.
    • Micromotion decreased by an average of 37% (98.04 to 61.97 μm) in the glenosphere contact condition.
    • Average von Mises stress decreased by 26% (3.29 to 2.42 MPa), with larger glenospheres showing greater micromotion reduction.

    Conclusions:

    • Increasing glenosphere size and enabling glenosphere undersurface contact significantly boosts implant-bone contact.
    • This enhanced contact area improves baseplate stability in reverse shoulder arthroplasty.
    • Glenosphere contact offers a potential strategy to improve fixation and reduce failure risk.
