HYPE® Acetabular Cup

The Hype® acetabular cup is an implant dedicated to primary total hip arthroplasty with a cementless fixation. The cup is designed to be combined with either a Biolox® delta ceramic liner or an UHMWPE liner.

Fixing screws (optional) of Ø 6.5 mm are available to secure the cup if required due to the bone quality. These screws are available in lengths ranging from 20 to 45 mm (in 5-mm increments).

This implant is part of the Hype® femoral stem range.

Characteristics and materials

Characteristics: 

  • The Hype® cup is available in diameters of 45 mm to 63 mm.
  • The HIC ceramic liner is intended for Ø 28, 32 and 36 mm femoral heads.
  • The HIPER liner has an overhang and is intended for Ø 22.2 and 28 mm femoral heads.
  • Fixing screws (optional) have a diameter of 6.5 mm and are available in a length of 20 to 45 mm (in 5 mm increments).

Materials:

  • The Hype® cup is made from titanium alloy + dual coating made of titanium spray and HA.
  • The screws are made from titanium alloy.
  • The HIC insert is made from Biolox® delta ceramic.
  • The HIPER insert is made from UHMWPE.

Instruments

  • One instrumentation set for the two versions of Hype® liner
  • Additional sets available:
    • for preparation and insertion of the locking screws.
    • for anterior approach and minimally invasive surgeries.

Indications

The Hype® cup is indicated in the following cases:

  • Osteoarthritis, post-traumatic osteoarthritis, rheumatoid arthritis, advanced joint destruction resulting from rheumatoid or traumatic arthritis, congenital hip dysplasia, bone fractures or avascular necrosis, following previous surgery (osteosynthesis, joint reconstruction, arthrodesis, hemiarthroplasty, or total arthroplasty).
  • According to the classifications: SOFCOT stage 1, 2, 3 or PAPROSKY type 1, 2A, 2B, 2C.

Ceramic is particularly suitable for use in young, active patients, reducing the rate of wear compared with conventional frictional torque.

Contraindications for the Hype® cup are as follows:

  • Acute or chronic local or systemic infections (cardiopathy, decompensated diabetes, continuous haemodialysis, reduced immune response, etc.).
  • Severe muscular, neurological or vascular deficiencies affecting the extremity concerned.
  • Bone destruction or loss, or poor bone quality likely to affect implant stability, severe osteoporosis, major deformity of the joint to be replaced, local bone tumours.
  • All related conditions which could compromise the function or implanting of the prosthesis.
  • Drug addiction, alcohol, tobacco or medicine abuse.
  • Mental incapacity of patients to understand the surgeon’s instructions.
  • Systemic or metabolic disorders.
  • Local bone tumours.
  • Obesity, excess weight, high level of physical activity, intense exercise, after a fall.
