SERF has studied and developed in association with a French group of experienced surgeons, a selflocking

femoral stem available in 4 cementless versions:

standard, standard collared, offset and coxa vara.


This stem relies on a proven concept; its conical shape and quadrangular section consistent with the original concept of the selflocking prosthesis. The modifications come from the research and development center and the technological know how of Serf. They are located in the proximal area with a dual layer coating particularly well studied to enhancing the primary and secondary fixation. A progressive increase in neck length provides a better anatomic adjustment of the joint.
