PTH-3 FEMORAL STEM


  • Explanation
  • Order Form

The medial and lateral pressure grooves were designed according to the different loading characteristics of the proximal bone and the prosthesis.

The width of the proximal femur, the distance between the prosthesis and the medial cortical bone of the lesser trochanter, was designed at 2 mm to ensure good bone growth and initial stability.

Vertical bars on the medial and lateral sides of the mid-distal end and on the anterior and posterior sides increase stability and the ability to prevent rotation.

The neck stem angle is designed with a minimum value of 107.98° and a maximum value of 154.75°.

Internal and external grooves are designed for different load characteristics of the proximal bone and prosthesis

Polished distal surface, offset stem tip design prevents stress concentration at the distal end and is designed to reduce thigh pain.

Designed with Ti+HA double coating.
