ECHELON◊ Revision Design and Technology
Fixation
HA on Porous Coating
The ECHELON Porous Plus HA prosthesis is a fully porous coated stem. Subsequently, a 50 micron hydroxyapatite layer is then applied onto the porous surface.
Range of Motion
Circulotrapezoidal Neck
Provides maximum ROM with minimal impingement, thereby reducing the risk of dislocation and wear. Neck length is increased for restoration of offset.
Optimum Taper Design
The 12/14 taper is optimized to avoid impingement on the cup and maximize ROM.
Versatility
Addressing Proximal Defects
Stems are available with standard collar and 15mm calcar platforms.
Progressive Offset and Sizing
Stem sizes range from 11 mm - 20mm in 1mm increments for improved canal fill and fixation. Femoral component offset progressively increases with increasing implant size. Offset ranges from 38mm - 62mm depending on the femoral head size chosen.
Simplicity
Simple Instrumentation and Technique
Instrumentation enhances a straightforward surgical technique, which optimizes OR efficiency and reproducible results.
Insertion Simplicity
The stem inserter threads into the implant to provide rotational control. A distally slotted, fluted stem generates lower bone strains during insertion than a solid fully coated stem of the same geometry.1
