Self-locking cementless hip stem Description The TrendHip® design concept combines the traditional features of a straight tapered and fully surface coated cementless hip stem. The rectangular self-locking stem ensures a reliable primary stable implant position and direct secondary periprosthetic bone contact to the hydroxylapatite coated surface. The implant range is available for standard and lateralized offset stems. The TrendHip® triple tapered shape additionally supports implant positioning inside the femoral cavity. Medial and horizontal grooves increase the bone contact area and axial implant stabilization. The hydroxylapatite surface is a combined double layer of rough titanium plasmaspray coating in the proximal stem part with decreasing thickness in the mid third stem section and smooth coating distally. Components TrendHip® hip stems are available with 12/14 tapers for modular heads. TrendHip® can be combined with Bipolar Cups or cemented and cementless acetabular implants for total hip arthroplasty. Aesculap acetabular systems Plasmacup® or Plasmafit® offer a 36 mm large head articulation with ceramic Biolox® delta components or Vitelene® (highly crosslinked polyethylene with vitamin E).
