The signal intensity of the condyle and retrodiscal tissue on MRI
| Condyle | Retrodiscal tissue | |||||
|---|---|---|---|---|---|---|
| High | Low | Normal | High | Low | Normal | |
| Dislocation | 18 (38) | 7 (15) | 11 (23) | |||
| Displacement | 10 (21) | 2 (4) | 8 (17) | |||
| No displacement | 2 (4) | 13 (28) | 2 (4) | 13 (28) | ||
| Lateral displacement | 2 (4) | 2 (4) | ||||
| Chip fracture | 2 (4) | 2 (4) | ||||
| Contralateral | 1 (5) | 20 (95) | 2 (10) | 19 (91) | ||
( ): % in total fractured or contralateral joints
p > 0.05 (statistically insignificant for signals of disc/retrodiscal tissue and fracture, chi-square test)
