CZMEDITECH TriGen InterTAN  Nail

Introduction

The TRIGEN™ INTERTAN nail was designed as a trochanteric portal intramedullary nail especially shaped for fractures of the proximal femur. The INTERTAN system offers anatomically shaped trapezoidal implants as opposed to conventional circular shaped intramedullary nails.

The INTERTAN system offers an integrated interlocking screw option to increase stability and resistance to intra-operative and post-operative femoral head rotation, thus eliminating excessive

sliding and the possibility of Z-effect. The INTERTAN screw is a 4th generation intramedullary nail combining the rotational stability of the original RUSSELL-TAYLOR™ Reconstruction Nail with the enhanced sliding and compression of the IMHS™ Intramedullary Hip Screw. The INTERTAN system screw utilizes the best of both concepts.

The option of a single lag screw device placed in the femoral head is available for rotationally stable proximal femur fractures. Devices in the proximal femur are at their greatest stress levels when the hip is placed through its flexion extension arc (ex: chair rise and climbing stairs). During this event, the trapezoidal shape of the INTERTAN system enhances stability of the implant within the femur. In addition, the integrated interlocking screw configuration imparts rotational stability in the femoral head and neck segment, and offers a greater resistance to cutout. With these features, the INTERTAN system provides an innovative treatment option for proximal femur fractures.

This next generation nail in the TRIGEN™ system provides these clear advantages:

Implants

• Additional strength and stability with a unique integrated interlocking screw and trapezoidal nail shape

• Improved resistance to femoral head rotation and cutout

• Active compression achieved through a linear motion without rotation

• Single subtrochanteric lag screw option for stable fractures below the lesser trochanter

• Preloaded cannulated set screw converts the construct to a fixed angle device

• The small proximal diameter of the nail promotes preservation of the lateral wall of the greater trochanter and gluteus medius tendon

• Clothespin tip for stress modulation in the femoral shaft

• Potential for improved patient mobility and recovery

Instrumentation

• Familiar, easy to use, minimally invasive TRIGEN instrumentation

• Anti-rotation bar maintains stability during drilling and screw insertion

• Alignment guides for proper lag screw placement in the femoral neck and head
