Percentages of the maximum von Mises stress in the subsets A, B, C of the lower vertebra (Fig. 4) due to different load cases (values for both sides of lateral bending – denoted as 1 and 2 – are given). The corresponding intact models were set to 100%. All cages were titanium and the cancellous bone had the same elastic modulus of 100 MPa
| Loading | A | B | C |
|---|---|---|---|
| Compression | 207 | 32 | 134 |
| Flexion | 307 | 20 | 100 |
| Extension | 38 | 51 | 165 |
| Lateral bending 1 | 144 | 38 | 154 |
| Lateral bending 2 | 218 | 30 | 97 |
