Comparison of head/stem corrosion in our study with that in Goldberg et al. [12]
| Study | Stem material | Head material | Number of heads | Average time in situ (months) | % corrosion severity | |||
|---|---|---|---|---|---|---|---|---|
| 1 | 2 | 3 | 4 | |||||
| Goldberg et al. [12] | Co-Cr-Mo | Co-Cr-Mo | 132 | 44 (1–156) | 38 | 34 | 20 | 8 |
| Current study | Co-Cr-Mo | Co-Cr-Mo | 7 | 26 (4–103) | 100 | |||
| Goldberg et al. [12] | Ti | Co-Cr-Mo | 89 | 44 (1–156) | 18 | 4 | 30 | 12 |
| Current study | Ti | Co-Cr-Mo | 15 | 21 (3–204) | 87 | 13 | ||
Our data were redistributed for comparison with Goldberg et al. [12]; thus, severity scores of 0 and 1 were combined to be equivalent to a Goldberg score of 1.
