Table 5. KL scores in those with sigmoid notch involvement.
| Radiographic parameter | Subgroup | KL score | p-Value |
|---|---|---|---|
| Axial sigmoid notch articular step-off | Step-off ≤ 1.0 mm (n = 11) | 1.6 (1.1) | 1.00 |
| Step-off > 1.0 mm (n = 1) | 1.3 (NA) | ||
| Coronal sigmoid notch articular Step-off | Step-off ≤ 1.0 mm (n = 11) | 1.5 (1.1) | NAa |
| Step-off > 1.0 mm (n = 0) | NA | ||
| DRUJ subluxation | Subluxation ≤10% (n = 16) | 1.2 (0.9) | 0.383 |
| Subluxation >10% (n = 8) | 1.5 (1.0) |
Notes: Data reported as mean (SD). p-Values are reported for Mann Whitney U-test.
