Profemur® TL

Product Introduction
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. With a three point fixation philosophy, the stem is shaped to allow both medial and lateral contact with the cortical bone. Plasma spray coating and anteroposterior taper allow contact in the frontal plane, while rotational stability is enhanced via distal grooves.
 
Family Options
  • Sizes 1–12
  • Straight (135o) and Varus (127o) Neck Angles
  • Short and Long Neck Lengths
  • Classic and Modular

    Profemur® Gladiator®

    Product Introduction
    Designed for primary hip replacement surgery, the Profemur® Gladiator® Hip Stem is a triple tapered wedge stem with a distinct geometry. The stem is designed with a reduced lateral shoulder convenient for tissue sparing techniques. With three point fixation, the stem’s shape also allows for medial and lateral contact with cortical bone. Plasma spray or HA coatings and an anteroposterior taper allow for contact in the frontal plane. And horizontal grooves are designed to more evenly distribute load forces, while vertical grooves assist with rotational stability.
    Family Options
    • Sizes 1–10 (Cement free) and sizes 4–12 (Cemented)
    • Straight (135o) and Varus (127o) Neck Angles
    • Short, Medium, Long Neck Lengths

      Profemur® L

      Product Introduction
      With a reduced lateral shoulder convenient for tissue-sparing surgical techniques, the Profemur® L is a tapered wedge stem used primarily for hip replacement surgery. The unique shape of this three point fixation stem allows for secure medial and lateral contact with the cortical bone. HA coating and an anteroposterior taper allow contact in the frontal plane. Rotational stability is enhanced by vertical grooves, while horizontal grooves are designed to maximize more even distribution of load forces.

        Profemur® Z

        Product Introduction
        A fourth generation design of the Zweymuller rectangular dual taper stem, the Profemur® Z Hip Stem is designed on the premise that there are advantages to placing a square peg in a round hole. With an optional proximal plasma spray designed for press fit, the square corners of the rectangular cross section wedge into cortical bone for rotational rigidity. By placing this rectangular cross section into a cylindrical femoral canal, cancellous bone is conserved to allow increased vascularization along the entire length of the stem.

        • Sizes 1–9
        • Straight (135o) and (127o) Neck Angles
        • Short and Long Neck Lengths
        • Grit Blast or Plasma Spray Coating

          Profemur® Am

          Product Introduction
          To accommodate proximal femoral curvature, the Profemur® Am Hip Stem offers an advanced anatomical design for left or right implantation in the patient’s femur. With an HA or plasma coating in the proximal portion, the stem is intended to create optimized proximal dimension for enhanced load distribution. For patient comfort, the highly polished distal portion is also reduced at the tip to minimize point contact in the thigh.
           
          Family Options
          • Sizes 1–9
          • Left and Right

            Profemur® Xm

            Product Introduction
            Designed with a highly polished surface for cemented hip replacements, the Profemur® Xm Hip Stem features dual taper geometry to promote cement engagement and enhance rotational stability. The highly polished, forged CoCr stem minimizes friction so the cement-implant interface discourages potential for wear. Radial compressive loading is optimized by design thanks to rounded edges on the stem. And a distal centralizer is used to allow distal stem engagement within the cement mantle.
             
            Family Options
            • Sizes 0–4
            • Highly Polished Surface

            Ream and Broach Stems

            Profemur® Renaissance®

            Product Introduction
            Designed to deliver both proximal and distal fixation, the Profemur® Renaissance® Hip Stem features a unique “Canal Filling” Hip Stem to maximize contact between the hip stem and the bone. The objective of this design is maximum stability via bone apposition. With primary fixation in the diaphysis, rotational stability is designed through use of distal splines. Different metaphyseal taper and flare options then accommodate differences in the proximal and distal bone geometry. A round distal tip then minimizes point contact after insert, designed to assist patient thigh comfort.
             
            Family Options
            • Sizes 10–16 (Reduced Flare) and sizes 10–18 (Standard Flare)
            • Straight (135o) and Varus (127o) Neck Angles
            • Short and Long Neck Lengths
            • Reduced and Standard Flares

              Short Stems

              Profemur® Preserve

              Product Introduction
              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. Saved bone can be valuable in the event a future revision is needed. This stem also features a reduced lateral shoulder and curved distal geometry ideal for tissue sparing surgical techniques such as the Anterior Approach. Plasma spray coating and double wedge taper geometry are designed to allow for proximal load transfer to discourage bone resorption typically caused by stress shielding.
               
              Family Options
              • Sizes 1–12
              • Straight (135o) and Varus (127o) Neck Angles

                Revision Stems

                Profemur® L

                Product Introduction
                Designed for revision cases, the PROFEMUR® L family is a line extension that features a collar to facilitate medial support. Distal slots also reduce stem stiffness to avoid fracture during stem insertion, and help minimize point contact to avoid thigh pain. In the short term after implantation, the extended hydroxyapatite coating is designed to encourage bone apposition.
                Family Options
                • Sizes 1–11
                • HA Coated

                  Profemur® Z

                  Product Introduction
                  A fourth generation of the Zweymueller design, the PROFEMUR® Z revision stem is designed with additional length compared to its primary option (40mm) in order to promote distal fixation in revision cases. The stem possesses a rectangular cross section and prominent lateral shoulder designed to facilitate rotational stability. The softer edges on the medial calcar area are designed to minimize stresses and risk of bone fissuration during stem insertion.

                    Profemur® R

                    Product Introduction
                    Designed to promote fit and fill, the PROFEMUR® R is a fully modular revision system. The tapered distal stems are designed to limit distal impingment and encourage proximal loading. They feature radial cutting splines to help optimize rotational stability, plus bowed medium and long options to accommodate natural femoral curvature. The 8 proximal bodies feature an ellipsoidal shape designed to minimize potential for excessive stress on the bone when inserting the component. Components are securely mated with the Morse taper connection and an axial fixation screw.
