Table 5: Mean change in VAS and MOXFQ after arthrodesis or silastic arthroplasty and analysis using t-tests.
| Mean pre-op score (SD) | Mean post-op score (SD) | Mean change in score (SD) | p-value | Arthrodesis vs. silastic arthroplasty | ||
| VAS | Arthrodesis (n = 36) | 55 (26.9) | 11 (17.0) | 44 (29.1) | < 0.0001 | *p = 0.002 |
| Silastic arthroplasty (n = 29) | 62 (20.5) | 38 (27.7) | 24 (20.5) | 0.0004 | ||
| MOXFQ | Arthrodesis (n = 36) | 59 (22.8) | 20 (20.2) | 38 (21.9) | < 0.0001 | *p = 0.0004 |
| Silastic arthroplasty (n = 29) | 62 (17.5) | 44 (27.6) | 18 (21.2) | 0.005 | ||
| *Greater improvement after arthrodesis than silastic arthroplasty | ||||||
