RFN-ADVANCED™ Retrograde Femoral Nailing System
STABILITY TO DO MORE™
The Retrograde Femoral Nailing System (RFN-Advanced™ System) is designed to improve fixation by reduced toggle and loss of reduction for distal femur fractures1. As part of the Advanced Nailing System, it is designed for simple to complex cases4 with increased fixation and stability1-6 and intuitive, connection instrumentation.8
Features & Benefits
Multi-planer, decending oblique screw pattern
- Two descending oblique screws target denser posterior condyles.
- Locking Polymer is built into the nail for angular stability in all distal locking screws without additional steps, end caps, or special instruments.1-3
- Designed to avoid the challenges associated with cross-threading and cold-welding.1-3
Distal Scew Density
- 3.5mm Variable Angle Locking Screws designed to fit around the nail and interlocking screws.4
Locking Attachment Washer (LAW)
- The addition of the Locking Attachment Washer increases the fixation strength by 44% compared to nailing alone.5
Condylar Nut and Washer
- Condylar Nuts increase surface contact with cortical bone to improve stability compared to standard screws.6
Periprosthetic Nail with 10° Distal Bend
- Periprosthetic Nail is designed to reduce the likelihood of an extension deformity that can result from a posterior entry point in TKA patients.7
Shared Base Instruments provide consistency to support reduction in storage, duplication and staff learning.8
- Secure retention instrumentation - Solid “screw to screwdriver” connection. Same drivers used for both screws, available in manual and power
- Quick connect latch – efficient assembly/disassembly
- Twist and lock – protection sleeves secured in aiming arm
- Simplified guided alignment – aiming arm supports LAW and Nut technique
Designed to help maintain alignment of the distal fragment, the Locking Polymer reduces screw toggle by 80% and holds the screw in position relative to the nail, increasing pull out strength up to 128%, compared to a nail without Locking Polymer.2,3,6
Nails designed with flats medially and laterally for a max width of 11.2mm to fit through narrow open box prostheses.7

The RFN-Advanced Retrograde Femoral Nailing System (RFNA) is intended to stabilize fractures of the distal femur and the femoral shaft, including:
- Supracondylar fractures, including those with intraarticular extension
- Combination of ipsilateral condylar and diaphyseal fractures
- Ipsilateral femur/tibia fractures
- Femoral fractures in multiple trauma patients
- Periprosthetic Fractures
- Fractures in the morbidly obese
- Fractures in osteoporotic bone
- Impending pathologic fractures
- Malunions and nonunions
- It is critical to ensure proper selection of the implant meets the needs of the patient anatomy and the presenting trauma
- Use of these devices is not recommended when there is systemic infection, infection localized to the site of the proposed implantation or when the patient has demonstrated allergy or foreign body sensitivity to any of the implant materials.
- Physician should consider patient bone quality to ensure it provides adequate fixation to promote healing.
- Conditions that place excessive stresses on bone and implant such as severe obesity or degenerative diseases, should be considered. The decision whether to use these devices in patients with such conditions must be made by the physician taking into account the risks versus the benefits to the patients.
- Compromised vascularity in the site of proposed implantation may prevent adequate healing and thus preclude the use of this or an orthopaedic implant.
