A stem centralizer is a component used in hip surgery, particularly during the implantation of cemented hip prostheses. It serves to ensure proper positioning of the femoral stem in the medullary canal and to ensure a uniform thickness of the cement mantle.

Key Features:
Material: Often made of UHMWPE (ultra-high molecular weight polyethylene) or PMMA (polymethyl methacrylate), the same material as bone cement.

Shape and Design: Typically round or pyramidal, designed to fit the distal tip of the femoral stem. Some models are hollow to allow the stem to subside without direct contact with the centralizer, thus avoiding pressure on the stem tip.

Function:
Centering: Helps center the femoral stem in the medullary canal, ensuring a uniform cement mantle around the stem.

Bone-prosthesis contact prevention: Avoids direct contact between the bone and the distal end of the prosthesis.

Cement mantle optimization: Helps maintain a consistent cement thickness, essential for the stability and longevity of the prosthesis.

Positioning: Distal centralizers are available, attached to the end of the stem, and proximal centralizers can improve cement penetration and cementing pressure in the proximal region of the femur.

Sizes: Available in various sizes to match the femoral canal diameter or the size of the cement restrictor.

Placement: Slipped onto the distal tip of the stem prior to implantation, sometimes with a thin layer of cement to ensure good adhesion.

The cemented cup is an acetabular component used in total hip replacements. Its main features include:

Fixation Type: Cemented, allowing for rapid postoperative mobilization.

Design: Often hemispherical to maximize bone preservation and ensure uniform distribution.

Materials: Typically made of ultra-high-density polyethylene (UHMWPE) for the main component, offering low abrasion. A radiopaque marking ring, often made of stainless steel, is included for surgical positioning and postoperative checks.

Stability and Mobility: Can be designed for dual mobility to reduce the risk of dislocation, with movement between the femoral head and liner, and between the liner and cup. Grooves on the external surface can increase grip and limit micro-movements.

Indications: Used in primary arthroplasty in patients at high risk of dislocation or in revision arthroplasty in cases of repeated dislocations. The choice between cemented and uncemented implants depends on factors such as patient age and bone quality.

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.

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.
