Cemented acetabular cup

Desciption

Cemented acetabular cup is intended for restoration of function and form of the natural joint, and for rehabilitation of patients with traumas and diseases of musculoskeletal system.

Construction

Cemented acetabular cup has a shape of hemisphere with lengthwise and transversal slots. In the top and bottom diametrical slots there are metallic rings that allow to control post-operational position of cup with help of x-ray. At the lower basis of the insert there is a hemispherical indent made for setting-up the prosthesis head.

Two modiifications are available: standard and truncated.

The cup is combined with metallic heads (D22.2 mm, 28 mm and 32 mm).

In case of severe acetabulum damage cemented cup can be used with protrusion ring.

Materials

Cemented cup is manufactured from UHMW PE (ISO 5834/2) - material with low coefficient of friction and relatively low wear rate. To learn more about the material, please visit Materials used.

Metal-polumer friction pair

Wear rate: 0.02-0.05 mm per year.

Metallic heads combine good mechanical parameters and high tribological characteristics. This friction pair ism optimal for stable and long-standing implants.

Survival rate 7 years in vivo: 95.2 per cent (Clinical Investigation D'Antonio et al.)

 Indications

  • Intense loss of substance and function of hip joint due to degenerative changes, post-traumatic, progressive arthritis deformans and traumas;
  • Avascular necrosis of the femoral bone head and fracture of neck and head of the femur;
  • After surgical operations of osteosynthesis, operation for restoration of joint function, arthrodesis.
