Alter Cementless Stem

Features:

• Gradually taper design increases axial stability and avoids stem subsidence.
• Reduced lateral shoulder enables the preservation of the great trochanter.
• Oblique cutting increases anti-rotational stability.
• Contoured distal tip enhances stem insertion.

Indications:

• Severe painful and/or disabled joint from osteoarthritis, traumatic arthritis, rheumatoid arthritis, or congenital hip dysplasia
• Avascular necrosis of the femoral head
