Association between cam morphology based on visual score and range of motion at 5‐year follow‐up (n = hips)
| Range of motion | Normal (n = 18) | Flattening (n = 38) | Prominence (n = 42) | Cam, P (degrees) a | Large cam, P (degrees) b |
|---|---|---|---|---|---|
| Flexion | 121° ± 8 | 116° ± 6 | 116° ± 7 | .001 (6°) | .30 (2°) |
| Abduction | 43° ± 6 | 41° ± 4 | 42° ± 5 | .40 (1°) | .71 (0°) |
| Adduction | 26° ± 6 | 27° ± 6 | 27° ± 6 | .80 (0°) | .90 (0°) |
| Internal rotation | 28° ± 10 | 26° ± 6 | 24° ± 8 | .12 (3°) | .033 (3°) |
| External rotation | 36° ± 6 | 34° ± 5 | 34° ± 7 | .17 (2°) | .84 (0°) |
| Extension | 22° ± 4 | 23° ± 5 | 22° ± 5 | .06 (1°) | .58 (1°) |
Values are expressed as mean ± standard deviation.
a
Cam morphology vs having no cam morphology. Difference between groups is also presented in degrees range of motion.
b
Large cam morphology vs having no large cam morphology. Difference between groups is also presented as the estimated mean difference in degrees range of motion.
Bolded P‐values indicate a statistically significant difference.
