Mammography result notification letters: are they easy to read and understand?
The letters we analyzed were written at levels too difficult for many patients to understand. Future investigations should explore clearer ways of communicating mammography results.
Failure of the locking liner ring and loosening of the acetabular cup are the primary causes of mechanical failure with constrained liners; polyethylene is an inadequate material for restricting motion of the hip to prevent instability. The durability of these devices is unlikely to improve unless the mechanical demands are modified through increased range of motion leading to less frequent rim impingement.
