General
The HELICA TPS stem design is based on the principles of a bone sparing procedure and the metaphysical anchorage of short stems established in the huma medicine.
It fulfills all requirements on a modern implant. The stem implant achieves an immediate primary stability and secures the stable anchorage required for osteointegration.
Modular Design
The different anatomic situations of the dysplastic and arthrotic hip joint require variable stem sizes for best implant fit.
Modularity of the stem implant is absolutely critical here.
The five stem sizes can be combined with three different flange sizes to fulfill these essential requirements.
The specifically developed surgical technique allows seating of the flange completely gap-free on the surface of the femoral neck osteotomy, in order to optimize load transfer.
