This article explains, in educational terms, femoral nailing — how the technology works and where it fits. Which implant and technique are appropriate depends on the fracture type, bone quality, and patient factors, and is determined by the treating orthopedic surgeon. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Fracture Fixation and Joint Reconstruction
Joint reconstruction encompasses hip and knee prostheses and arthroscopy systems, extending the portfolio beyond acute fracture care into reconstructive surgery. Orthopedic trauma solutions address the fixation of fractures and the reconstruction of joints, using implants intended to stabilize bone so that healing can occur in a corrected position. Which implant and technique are appropriate depends on the fracture type, bone quality, and patient factors, and is determined by the treating orthopedic surgeon.
Femoral Nailing and PFN
Femoral nailing addresses fractures of the femoral shaft and, in the case of the proximal femoral nail (PFN), fractures of the proximal femur and trochanteric region. Anatomical curvature that matches femoral anatomy and a low-profile proximal geometry are intended to support accurate placement and fit. INVAMED's CytroFIX Intramedullary Femoral Nail is built from Ti-6Al-4V medical-grade titanium; per invamed.com content surfaced via the search index, the intramedullary nail range covers femoral (9 to 13 mm diameter), tibial, and humeral fractures within a system of 35+ implant variants. The specific nail and locking strategy are chosen by the surgeon based on the fracture location and bone quality.
Design and Technical Notes
INVAMED's CytroFIX system is organized by implant type and anatomical region, spanning intramedullary nails, plates, and screws manufactured from medical-grade titanium. Implants are intended for use by trained orthopedic surgeons and per the IFU. Fracture location and pattern strongly influence the choice among intramedullary nailing, plating, and screw fixation. Bone quality, including osteoporosis, is a key factor in favoring fixed-angle locking constructs where screw purchase may be reduced.
Key Considerations
- Bone quality, including osteoporosis, is a key factor in favoring fixed-angle locking constructs where screw purchase may be reduced.
- Nail diameter and length, plate contour, and screw configuration are selected to match the individual anatomy.
- Manufacturer statements about the CytroFIX range, including the 35+ implant variants figure, reflect the company's product information rather than guaranteed clinical outcomes.
Frequently Asked Questions
What diameters do the femoral nails come in?
According to invamed.com content surfaced via the search index, CytroFIX intramedullary nails cover femoral fractures in the 9 to 13 mm diameter range, along with tibial and humeral options.
What material are CytroFIX implants made from?
INVAMED describes CytroFIX implants as medical-grade titanium (Ti-6Al-4V ELI), selected for high strength, corrosion resistance, and biocompatibility, with an anatomical design and interlocking options.
Who decides which implant is used?
A qualified orthopedic surgeon selects the implant based on the fracture, bone quality, and patient factors; this article is educational and not a treatment recommendation.

Clinical and Technical Context
The lengthening protocol, rate, and endpoint are determined by the treating surgeon for each patient. Manufacturer statements about the CytroFIX range, including the 35+ implant variants figure, reflect the company's product information rather than guaranteed clinical outcomes. Nail diameter, length, and locking configuration are selected by the surgeon based on the fracture and the patient's anatomy. Locking plates have threaded holes that lock screws at a fixed angle to create angular stability, which the site FAQ notes is particularly relevant for osteoporotic bone, whereas non-locking plates rely on friction between the plate and bone.
