TRJ® Hip Stem
Trochanter retaining joint replacement
The TRJ® hip prosthesis stem is implanted without cement. The stem design is based on many years of experience with a conical diaphyseal anchorage in the femur.
The double tapered shape of the uncoated and surface radiated TRJ® hip stem straightens at the proximal lateral end so that the greater trochanter is preserved to the greatest possible extent during implantation.

Rasp Design
The TRJ® rasp concept with a modular disconnected trochanter rasp supports a muscle and trochanter preserving bone preparation with a precise diaphyseal stem design.
Implant Range
The TRJ® hip prosthesis stem can be combined with cementless and cemented acetabular implant systems. The modular cup system Plasmafit® allow a 36 mm articulation with a vitamin E stabilized highly crosslinked polyethylen Vitelene® starting by a 50mm outer diameter.
TRJ® stems are available in a range of sizes for different femur morphologies and correction of pathological joint and leg length anatomies.
The slim TRJ® neck design with cone 12/14 allows an optimized range of motion for the implantation of AESCULAP® head and cup components.
Minimal Invasive
The combination of the TRJ® system with the AESCULAP® MIOS® approach instruments (Minimally Invasive Orthopaedic Solutions) ensures gentle and precise implantation techniques for standard minimally invasive surgical approaches to the hip joint.
