Summary

The Ring UPM uncemented hip implant failed due to polyethylene wear, causing bone loss and difficult revisions. This study advises against using non-metal-backed polyethylene acetabular components in total hip arthroplasty.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Failure Analysis

Background:

  • The Ring UPM uncemented total hip arthroplasty utilizes a metal-on-plastic design.
  • Acetabular cup loosening and subsequent polyethylene debris generation are known complications in hip arthroplasty.

Purpose of the Study:

  • To investigate the mode of failure for the Ring UPM uncemented acetabular component.
  • To analyze the consequences of this failure mode on surrounding bone stock and revision surgery.

Main Methods:

  • Case review of eight patients experiencing failure of the Ring UPM uncemented acetabular component.
  • Histopathological analysis of polyethylene debris and associated granulomata.
  • Radiographic assessment of osteolysis and bone stock loss.

Main Results:

  • Erosion of the acetabular cup's external surface led to early loosening in all eight cases.
  • Significant polyethylene debris production resulted in massive granulomata and extensive osteolysis of the acetabulum and femur.
  • Revision surgery was complicated by substantial loss of bone stock.

Conclusions:

  • The failure mode of the Ring UPM uncemented acetabular component is characterized by external surface erosion and subsequent polyethylene debris-induced osteolysis.
  • The use of uncemented, non-metal-backed polyethylene acetabular components is associated with severe complications and should be avoided in total hip arthroplasty.
