HYPE^® Stems

Characteristics :

• Stems are available in short and standard, cementless and cemented, collared and collarless versions.
• Homothetic size progression of stem collars (except for the coxa vara stem).
• CCD angle : 120° for the coxa vara stem and 130° for other stems in the range.
• 12/14 (5°43’’) taper which needs to be used with SERF “I”, “D”, or “C” heads with the same 12/14 taper.

Materials :

• Cemented stems : stainless steel.
• Cementless stems : titanium alloy with titanium spray + dual coating made of titanium spray and HA.
• Femoral heads: “I” made from stainless steel and “D” made from Biolox^® delta ceramic. Beside and only for US market femoral heads “C” in cobalt-chromium is also available.

• The same instrumentation set for all standard-length stems.
• Additional set for Hype^® Mini stems.
• A wide choice of broach handles for the different approaches : posterior, posterolateral, anterior and anterolateral.

Hype^® stems are indicated in the following cases :

• First-stage surgery;
• Advanced joint destruction resulting from rheumatoid or post-traumatic arthritis;
• Primary or secondary osteoarthritis, displaced subcapital and transcervical fracture as well as for Paprosky type I to IIB bone defects.

Hype^® mini implants are more specifically indicated for anterior approaches or when the use of a shorter stem is more appropriate.

Contraindications of Hype^® stems are as follows :

• Acute or chronic local or systemic infection (cardiopathy, decompensated diabetes, continuous haemodialysis, reduced immune response, etc.);
• severe muscular, neurological or vascular deficiencies affecting the extremity concerned;
• Bbone 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;
• systemic or metabolic disorders;
• mental incapacity of patients to understand the surgeon’s instructions;
• drug addiction, alcohol, tobacco or medicine abuse;
• local bone tumours;
• obesity, excess weight, high level of physical activity, intense exercise, after a fall;
• size-1 Hype^® SCC and Hype^® SCS stems must only be used in patients weighing less than 55 kg;
• size-2 Hype^® SCC, Hype^® SCS and Hype^® SCL stems must only be used in patients weighing less than 70 kg;
• hype^® Mini stems are not recommended for use in obese or overweight patients;
• the size-2 mini Hype^® stem is not recommended for use in patients weighing 70 kg or over;
• the size-2 Hype^® SCV stem must only be used in patients weighing less than 70 kg.

Hype^® stems are indicated in the following cases :

• • • osteoarthritis;
    • femoral neck fracture;
    • osteonecrosis of the femoral head.

Hype® SCS, SCC, SCL, SCV, SCC Mini, and SCLA Mini hip stems are intended for press-fit use.

Hype® mini implants are more specifically indicated for anterior approaches or when the use of a shorter stem is more appropriate.

Contraindications of Hype® stems are as follows :

• • • Infection of the concerned limb;
    • any contraindication to surgery or anesthesia;
    • severe muscular, neurological or vascular deficiencies affecting the limb concerned;
    • destruction, loss or poor bone quality that could affect the stability of the implant, serious deformation of the joint that needs replacing;
    • local bone tumours;
    • any associated disorder that could compromise the function or the implementation of the prosthesis;
    • obesity;
    • intense activity or intensive;
    • sports training.
