45 patients randomized to receive either a cemented or a non-cemented stem were studied . 2 years after the operation gait analysis was performed with a 16-camera motion capture system together with 2 force-plates. Hip kinematics and kinetics were analysed and 70 subjects served as controls.
Acute cervical femoral neck fracture patients randomized to either cemented or non-cemented stem. The investigators used gait analysis to evaluate if patients operated with a cemented stem showed more favourable hip kinematics and kinetics when compared with a group of patients operated with a non-cemented stem.
