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. 

TRI-LOCK®   Bone Preservation Stem

Features & Benefits

Extensive Size Range

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.
 

GRIPTION® Porous Coating

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

Direct Lateralization

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.

Bone Preserving

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.
