MODULAR KNECKS
Designed in 1985 by Cremascoli (Wright), with more than 300,000 stems in primary and revision prosthesis implanted up to date.
Manufactured in titanium, 12/14 oval patented cone. Intensively proved by force tests, wear without corrosion risks in the neck-stem interphase.
Reasons to use PROFEMUR modular kneck system
• They enable the use of different types of articulations in revisions.
• They adjust for use in valgus necks for hips dysplasia replacement.
• They eliminate the need of XL heads (with cervical collar).
• They improve the mobility and stability rank with combinations of varus/ valgus and ante/retro version.
• They can be used with anterior, posterior or minimally invasive opening.
• Kinematic improvement: they recreate rotation centre of the appropriate femoral head.
• Easier for revisions; only neck and head.
• They enable “offset” adjustments and leg length without a risk between them.
• Clinically and laboratory verified.
• It enables the final adjustment to correct “offset”, leg length, version and varum valgus to compensate the position of the stem or acetabular cup.
