PRIMARY OR REVISION, CEMENTED OR CEMENTLESS, STANDARD OR LATERALIZED
The design rationale of the STEMSYS implant is based on the self-blocking concept. The cementless versions are made of titanium alloy and coated with either single hydroxyapatite layer or dual coating of porous titanium and hydroxyapatite. The cemented versions are made of high nitrogen content stainless steel and are fully polished.
The cementless self-blocking concept has been validated by over 25 years of clinical use. The main characteristics are an immediate primary stability and a long term biological secondary fixation.
STEMSYS is designed and manufactured in France, and includes the complete EVOLUTIS know-how in the industrial fileds of conception and manufacture of cementless femoral implants: more than 30.000 stems implanted since 2001 in France, Europe et in the world, with outstanding clinical results.
SPECIFICATIONS
- micro-grooved 12/14 taper
- cylindrical fully polished and reduced diameter neck
- NSA (neck-shaft angle) available in standard (135°) and “lengthened” lateralised (128°) versions
- single neck length (except sizes 7 to 9: -3.5mm)
- choice of collared and collarless versions
- unique metaphyseal macrostructure oriented along the dynamic load axis
- choice of 4 surface finish (with and without cement)
- choice of 2 stem lengths in primary cementless stems: normal or -15mm (on average)
- revision cementless stems available either with distal slots or distal tranverse locking
- long and extra-long option (up to 320mm) in distal tranverse locking revision
PROXIMAL RECONSTRUCTION IN ULTIMATE SITUATIONS
The PRIUS system (Proximal Reconstruction In Ultimate Situations) is adapted to the reconstruction and the osteosynthesis of the proximal femur in cases of important losses of bone stock, and cases of invasive ablation of the material to be revised.
Indicated for per-trochanteric fractures, revisions of SOFCOT stages 2 and 3, and for revisions associated with a trans-femoral approach, the PRIUS system is modular. The system articulates around a proximal component available in 4 lengthes and an intra-medullary component available in right or curved versions, and in several lengthes and diameters.
The femoral implant can be completed by a hook-plate meant to re-attach a trochanteric fragment, or to provide synthesis for a trans-femoral flap. The hook is planned to be directly secured to the proximal component.
The hook-plate can also be used alone for indications of pseudarthrosis of the greater trochanter or osteosynthesis of a sub-implant femoral fracture.
SPECIFICATIONS
- 4 proximal components with same proximal volume, available in lengthes 65, 75, 85 or 95mm
- proximal components coated with double layer of porous titanium and hydroxyapatite
- intra-medullar components made of gritblasted only titanium alloy
- 6 diameters of intra-medullar components, from 10 to 20mm by increment of 2mm
- straight intra-medullar components available in 3 lengthes: 115, 145 and 175mm
- finned intra-medullar components meant for stabilization in rotation and in subsidence
- curved intra-medullar components available in length 205mm only
- curved intra-medullar components with distal tranverse locking-pin option
- trochanteric hook-plates available in 5 lengthes: from 100 to 280mm
