Review OF THE LITERATURE

An analysis of the literature on the subject allows us to identify the most frequent complications. These are:

1. Wear
2. Aseptic loosening
3. Recurrent dislocation

Bozic et al. J Bone Joint Surgery, 87-A, 2005

The use of cementless implants, hard-hard friction couples and dislocation prevention techniques tend to decrease these complications.

Dislocation prevention techniques include:

1. Large diameter femoral heads
2. Tapered prosthesis necks (small diameter)
3. Reproduction of the correct musculo-ligamentary tension     (muscular balance)
4. Orientation of the implants
