Cemented Femoral Stem

The characteristics of a cemented femoral stem generally include the following:

Material and Finish:
Made of stainless steel or pure titanium.
Highly polished surface to minimize wear between the prosthesis and the cement mantle.

Design and Shape:
Simple and effective shape with proximal support.
Homothetic stem progression.
Tapered design helps transform vertical loads into compressive forces.
Neck-shaft angle of 127° or 130° for increased stability and reduced risk of dislocation.
Often collarless to prevent bone resorption due to stress shielding.

Fixation and Stability:
Fixed with bone cement, which holds it securely in position within the femur.
The unique centralizer design can provide space for stem subsidence.

Indication:
Indicated for acute traumatic fractures of the femoral head or neck.
Used in total hip arthroplasty, including cases of altered anatomy such as congenital hip dysplasia.
