Demographics, gait speed, radiographic measures, and the HJC-to-AEP distance (mean ± SD) of DDH and control subjects.
| DDH (N = 15) | Control (N = 15) | P-value | |
|---|---|---|---|
| Age (years) | 26.5 ± 7.9 | 24.6 ± 6.3 | 0.62 |
| Height (m) | 1.66 ± 0.07 | 1.67 ± 0.06 | 0.85 |
| Mass (kg) | 62.7 ± 9.3 | 61.9 ± 7.8 | 0.79 |
| Body-mass index (kg/m2) | 22.7 ± 2.4 | 22.3 ± 2.3 | 0.64 |
| Gait speed (m/s) | 1.37 ± 0.15 | 1.39 ± 0.15 | 0.59 |
| Lateral Center-Edge Angle (degrees) | 10.5 ± 9.2 | N/A | - |
| Acetabular Inclination (degrees) | 18.0 ± 8.4 | N/A | - |
| HJC-to-AEP distance (mm) | 9.3 ± 2.5 | 5.9 ± 1.4 | <0.01 |
Radiographic measurements of acetabular anatomy were only made for the DDH subjects. HJC, hip joint center; AEP, acetabular edge plane.
