Mallory-Head® Modular Calcar Revision System

The Mallory-Head^® Modular Calcar System offers unlimited flexibility in addressing proximal-distal mismatch in revision hip surgery.

The modular design allows for independent selection of both proximal and distal components, and the trochanteric claw provides solid re-anchoring for existing trochanteric bone. The multiple calcar options fill the proximal femur adequately and may encourage continuous bone remodeling, leading to a more stable, clinically successful prosthesis.

Mallory-Head Modular Calcar Hip

• Documented 100% survivorship in patients with severe bone loss¹
• Forged titanium alloy construct
• Titanium Porous Plasma Spray ingrowth surface
• Five proximal body sizes in each of 3 resection level options
• Multiple distal stem options (straight, bowed, splined, porous)

Proximal Options

The modular calcar proximal optims allow the surgeon to fill the proximal femur adiguality and stress the calcar bone with the platform. 3 Resection levels allow placement of bone with implant.

• Calcar platform allows load to be transferred to proximal bone
• Three resection levels (34mm,45mm and 55mm)
• Five body sizes in each resection level (A,B,C,D and E)
• Medial keel to aid in the prevention of rotation
• Titanium closed pore plasma spray
• Trochanteric bolt claw allows reattachment of trochanter
• Lateral holes to allow for additional wire fixation
• Macro sizes available in 65-A, 75-A, 45-F, 55-F and 55-G
