Abstract EN
Dynamic hip kinematics during weight-bearing activities were analyzed for six healthy subjects.
Continuous X-ray images of gait, chair-rising, squatting, and twisting were taken using a flat panel X-ray detector.
Digitally reconstructed radiographic images were used for 3D-to-2D model-to-image registration technique.
The root-mean-square errors associated with tracking the pelvis and femur were less than 0.3 mm and 0.3° for translations and rotations.
For gait, chair-rising, and squatting, the maximum hip flexion angles averaged 29.6°, 81.3°, and 102.4°, respectively.
The pelvis was tilted anteriorly around 4.4° on average during full gait cycle.
For chair-rising and squatting, the maximum absolute value of anterior/posterior pelvic tilt averaged 12.4°/11.7° and 10.7°/10.8°, respectively.
Hip flexion peaked on the way of movement due to further anterior pelvic tilt during both chair-rising and squatting.
For twisting, the maximum absolute value of hip internal/external rotation averaged 29.2°/30.7°.
This study revealed activity dependent kinematics of healthy hip joints with coordinated pelvic and femoral dynamic movements.
Kinematics’ data during activities of daily living may provide important insight as to the evaluating kinematics of pathological and reconstructed hips.
