简要总结

The authors hypothesize that a pelvic kinematic disorder, demonstrated by a significant decrease in sacral slope, is associated with the risk of instability of total hip prosthesis, the sacral slope being measured by an EOS imaging system during the transition to sitting in unstable patients versus patients with no history of instability.
