From: Mid-term subsidence and periprosthetic radiolucency of the AMIStem: a 5-year EBRA-FCA analysis

Parameter Subsidence at the latest follow-up, mean (SD) p value

• < 65 years (n = 35) 1.87 ± 1.01 mm
Offset
• Standard (n = 67) 2.05 ± 1.13 mm > .05
• Lateral (n = 33) 1.84 ± 1.32 mm
Head size
• 28 mm (n = 48) 1.83 ± 1.03 mm > .05
• 32 mm (n = 52) 2.12 ± 1.33 mm
Bearing couples
• Metal on crosslinked polyethylen 1.91 ± 1.03 mm > .05
• Ceramic on crosslinked polyethylen 2.17 ± 1.61 mm
Dorr proximal femur morphology
• Type 1 (n = 18) 1.96 ± 1.20 mm > .05
• Type 2 (n = 68) 1.92 ± 1.07 mm

  1. Values are given as mean and standard deviation (SD). None of the investigated parameters showed a statistical significant influence on subsidence at the latest follow-up, indicated by a p value > 0.05
