  • B. Braun Melsungen AG - Products - TRJ® Hip Stem System
    Products Orthopaedics Hip Arthroplasty TRJ Hip Stem System TRJ Hip Stem System Trochanter preserving joint arthroplasty Description 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 The newly developed TRJ rasp concept with a modular disconnected trochanter rasp supports safe muscle and trochanter preserving bone preparation with a very precise diaphyseal stem design The eccentric distal TRJ stem tip simplifies the minimally invasive implantation in the femur and prevents the risk of varus stem positioning The TRJ range of stems is available in a range of sizes standard and lateralized and allows universal adjustment to different femur morphologies and correction of pathological joint and leg length anatomies Implant Range The TRJ hip prosthesis stem can be combined with cementless and cemented acetabular implant systems The modular cup systems Plasmacup and Plasmafit allow both 36 mm ceramic ceramic large head articulation with Biolox delta components and ceramic polyethylene or metal polyethylene with highly crosslinked Vitelene polyethylene with vitamin E Rasp System The newly developed TRJ rasp concept includes a modular disconnected trochanter rasp so that the main rasp can be cut free in the proximal lateral section The femoral rasp preparation is designed to anchor into the region of the distal bearing bone structures The denticulation of the TRJ main rasp does not come into contact with the greater trochanter and the adjacent abductors This allows a precise neutral positioning of the rasp in the bone There is no pressure on the soft tissue or against the greater trochanter The

    the third generation of straight polished hip stems The polished Trilliance hip stems are triple tapered and produced from forged CoCr alloy Trilliance implants provide a linear increasing lateralization by implant size The CCD is 135 deg Trilliance implant size parameters increase proportionally by size The mechanical strength of the design features is proven by mechanical fatigue testing The nominal thickness of the Trilliance cement mantle can be influenced by the rasp and implant size selection Rasp and implant measurements are equal The fully teethed rasps provide an additional length of 5 mm to include the position of the optional modular distal centralizer The Trilliance distal centralizers are dedicated to each implant size and are produced from PMMA The cap type design allows a safe axial stem setting within the cement mantle Principle The basic principle of hip implant fixation with bone cement is based on the long term mechanical integrity of the bone cement layer between implant and bone The success of cemented hip replacement depends on the mechanical properties of bone cement sufficient thickness of the cement mantle cement penetration into the bone and the accurate method of surgical cement application Since the beginning of cemented hip replacementthe
