Product Overview
Short stem philosophy
-Designed to conserve bone in a primary Total Hip
Arthroplasty, the Profemur® Preserve hip stem offers
a shorter design that allows more of the patient’s
natural bone to remain in place as compared to a
longer distal stem. This stem also features a reduced
lateral shoulder and curved distal geometry ideal for
tissue sparing surgical techniques such as the Superior
and Direct Anterior approaches. Plasma spray coating
and the "tri-taper" geometry are designed to allow for
initial fixation and proximal load transfer to discourage
bone resorption typically caused by stress shielding.
Design features
Rotational stability:
- Trapezoidal cross-section and wedge shaped
geometry allow for four-point fixation along the four
corners within the femoral canal1
Fixation:
- Proximal plasma spray coating and distal grit-blasted
surface provide press-fit, initial fixation and bone
apposition
Ease of hip stem insertion:
- Facilitated by a reduced lateral shoulder and curved
distal geometry
Intraoperative flexibility:
- Consistent medial curvature and optimized neck
lengths aid in proper sizing and fit
Product options:
- Sizes 1–12
- Straight (135°) and Varus (127°) neck angles
- Classic and modular
