Summary

Backside polyethylene damage is common in reverse shoulder arthroplasty (RSA) humeral components, occurring in nearly all explants. While the articular side shows more damage, backside wear is present and requires further study for clinical significance in osteolysis.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Implant Wear Analysis

Background:

  • Aseptic loosening and osteolysis are complications of reverse shoulder arthroplasty (RSA).
  • Polyethylene (PE) damage on the articular surface is documented, but backside wear in RSA remains uninvestigated.
  • Understanding backside wear is crucial for addressing implant failure and osteolysis.

Purpose of the Study:

  • To compare backside and articular surface damage in explanted RSA humeral liners.
  • To determine if specific quadrants exhibit higher damage propensity.
  • To identify common backside PE damage modes.

Main Methods:

  • Analysis of 21 explanted RSA humeral liners retrieved between 2005 and 2014.
  • Microscopic examination (×10-30 magnification) and grading of damage using the modified Hood score.
  • Comparison of damage location and modality between articular and backside surfaces.

Main Results:

  • Damage was observed on the articular surfaces of all 21 liners and the backside of 20 liners.
  • Total damage scores were significantly higher on the articular surface compared to the backside (P < .001).
  • No significant difference in damage was found among quadrants on either the backside (P = .44) or articular surface (P = .08).

Conclusions:

  • Backside polyethylene damage is a frequent finding in retrieved RSA humeral components.
  • Although articular damage is more severe, backside wear is nearly ubiquitous.
  • The clinical impact of backside wear on PE particulate disease and osteolysis in RSA warrants further investigation.
