TRI-LOCK® 

Bone Preservation Stem

The TRI-LOCK® Bone Preservation Stem is based on the well documented 35-year clinical heritage of the original TRI-LOCK Stem. The tapered-wedge design of the TRI-LOCK BPS Stem ensures intimate implant contact proximally, providing both rotational and axial stability, while increasing the opportunity for biological fixation. 

TRILOCK BONE PRESERVATION STEM

Features & Benefits

  • TRILOCK BONE PRESERVATION STEM

    Extensive Size Range

    The TRI-LOCK BPS System features 13 stem sizes which allows surgeons to address a wide range of patient anatomies. Consistent intervals between each stem size help achieve proper fit within the femur.

  • TRILOCK BONE PRESERVATION STEM

    GRIPTION® Porous Coating

    GRIPTION Porous Coating is specifically engineered to maintain mechanical integrity under shear, compression, torsion and tension force. This advanced, three-dimensional fixation is designed to enhance initial stability, which may lead to long-term biological fixation.1

  • TRILOCK BONE PRESERVATION STEM

    Direct Lateralization

    The TRI-LOCK BPS Dual Offset options provide surgeons the ability to lateralize by 6mm-8mm to help manage soft tissue laxity. The offset range is 30mm-50mm depending on stem size. This direct lateralization can enable femoral offset restoration without affecting leg length.

  • TRILOCK BONE PRESERVATION STEM

    Bone Preserving

    The reduced lateral shoulder, thin geometry and optimized length compared to the original TRI-LOCK Stem reduces the amount of bone removed from the patient.
