Product Overview
Tapered wedge stem philosophy
- Designed for primary hip replacement surgery, the
Profemur® TL hip stem is a dual tapered wedge stem
with a unique geometry. It features a reduced lateral
shoulder convenient for tissue-sparing surgical
techniques. Allowing for three point fixation, the
stem is shaped to contact cortical bone medially and
laterally, while conserving cancellous bone anteriorly
and posteriorly. Plasma spray coating and
anteroposterior taper allow contact in the frontal
plane, while rotational stability is enhanced via distal
grooves.
Design features
Tapered wedge geometry:
- Tapered both anteroposteriorly and mediolaterally.
Wider M/L dimension contacts cortical bone medially
and laterally, as the slim A/P dimension assists in
torsional stability and conserves bone
Rotational stability:
- In addition to slim A/P dimension, the distal groove
helps promote rotational stability by acting as a
cavity for bone apposition
Increased fixation:
- Proximal portion of stems are coated with plasma
spray coating to provide 1mm of additional press-fit
Ease of stem Insertion:
- Facilitated by a reduced lateral shoulder, glass-
beaded distal texture, and a rounded distal tip that
minimizes point contact after implantation
Product options:
- Sizes 1–12
- Straight (135°) and varus (127°) neck angles
- Short and long neck lengths
- Classic and modular
