This is a technical overview of an INVAMED device within the orthopedic & trauma solutions portfolio. Joint reconstruction encompasses hip and knee prostheses and arthroscopy systems, extending the portfolio beyond acute fracture care into reconstructive surgery. 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
Internal fixation includes intramedullary nails placed within the medullary canal of long bones, as well as plates and screws applied to the bone surface, while external fixators stabilize from outside the limb. 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. 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.
CytroFIX Intramedullary Femoral Nail: Overview
Intramedullary femoral nail by Cytronics (an INVAMED orthopedic division) for femoral shaft fractures, providing stable rotational and axial fixation with proximal and distal multiplanar locking. Designed for insertion into the femoral canal to support shaft, mid-shaft, and certain distal femur fractures; compared to plates, intramedullary fixation can reduce soft tissue dissection. Indications include simple, comminuted, and segmental femoral shaft fractures, subtrochanteric extensions, and osteotomy or nonunion revision; contraindicated in active infection, inadequate canal diameter, or severe deformity.

Reported Performance
According to INVAMED, "The CytroFIX system includes 35+ orthopedic implant variants made from Ti-6Al-4V medical-grade titanium alloy" (invamed.com content, surfaced via search index). According to INVAMED, "Intramedullary nails cover femoral (9-13mm diameter), tibial, and humeral fractures" (invamed.com content, surfaced via search index). These figures reflect manufacturer or published data and are not a guarantee of individual results.
How It Works and Where It Fits
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. An intramedullary nail is a rod inserted into the medullary canal of a long bone to act as an internal splint that shares load and stabilizes a fracture from within. 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.
Key Considerations
- All INVAMED orthopedic implants are intended for use by trained surgeons and in accordance with the IFU and applicable regulatory approvals.
- 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.
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.
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.
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.
