Arcos® One-piece Femoral Revision System

System Features

This system is designed to address the distinct needs of individual patients, while simplifying surgical workflow and reducing instrumentation burden.

 

Collared Broach Body Femoral Stem

Designed to provide rotational stability and proximal offloading to address complex primary and simple revision (Type I and II femoral defects) total hip arthroplasty (THA).

 

Non-collared Broach Body Femoral Stem

Shares many of the same design features as the collared stem option

 

Calcar Replacing Femoral Stem

Designed for cases that involve deficiencies in the medial calcar, where proximal femoral support is desired. This design maintains the same features of the Non-collared Broach Body stem, with the addition of a calcar shelf to address Type IIIa femoral defects.

 

Specifications

Collared Broach Body Femoral Stem

• Available in 175 mm stem length
• Proximal collar designed to control stem seating depth
• Forged titanium alloy (Ti-6Al-4V) substrate allows for stress transfer to preserve cortical density
• Fully cylindrical distal geometry provides initial fixation distally for the highest level of cortical bone-to-implant contact
• Reduced medial geometry designed to minimize impaction force on proximal bone during bone preparation and implantat
• Clinically proven PPS© coating allows for initial scratch-fit stability and long-term biological fixation
• Standard (135⁰) and high offset (130⁰) options reproduce various patient anatomies without lengthening the leg
• Ten sizes: 9.5*, 11-16, 18, 20 and 22 mm

 

Non-collared Broach Body Femoral Stem

• Available in 210 mm stem length
• Dual distal relief aims to improve surgical efficiency by providing easier insertion into canal and eliminating the need for left and right specific femoral implant options
• Ten sizes: 9.5*, 11-16, 18, 20 and 22 mm

 

Calcar Replacing Femoral Stem

• +0 mm level calcar shelf designed to control stem seating depth
• Available in 210 mm stem length
• Dual distal relief aims to improve surgical efficiency by providing easier insertion into canal and eliminating the need for left and right specific femoral implant options
• Ten sizes: 9.5*, 11-16, 18, 20 and 22 mm

 

Benefits

Unique Size Range

Address a large number of femora, including patients of small stature

 

Dual Distal Relief

210 mm features a dual distal relief, allowing for easier insertion into the femoral canal, accommodating the bow of a femur in both left and right femurs

 

Flexibility

Proximal loading collared or collarless broach body

 

Controlled stem seating depth

Calcar shelf designed to control stem seating depth in cases with medial calcar defects

 

Simplified Workflow

Reduced instrumentation for intraoperative efficiency, simplified workflow and reduced cost burden
