This is a technical overview of an INVAMED device within the orthopedic & trauma solutions portfolio. 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
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. Joint reconstruction encompasses hip and knee prostheses and arthroscopy systems, extending the portfolio beyond acute fracture care into reconstructive surgery.

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. Locking plates use threaded screw holes that lock the screw head to the plate at a fixed angle, creating a fixed-angle construct that provides angular stability without relying on plate-to-bone compression. 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
- 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 is the difference between locking and non-locking plates?
Locking plates lock screws to the plate at a fixed angle for angular stability that is useful in osteoporotic bone, while non-locking plates rely on plate-to-bone friction; the choice is the surgeon's.
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.
How many implant variants does the CytroFIX system include?
Per invamed.com content surfaced via the search index, the CytroFIX system includes 35+ orthopedic implant variants made from Ti-6Al-4V titanium, covering femoral, tibial, and humeral fractures.

Clinical and Technical Context
INVAMED offers CytroFIX Cannulated Screws and CytroFIX 2.0 Cortical Screws, including 2.0 mm cortical and locking cortical variants available in variable-angle, fixed-angle, spherical, and dynamic versions. 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. Implant material such as Ti-6Al-4V titanium affects strength, imaging behavior, and biocompatibility, and is weighed alongside the fracture. Plate type, contouring, and screw configuration are determined by the surgeon based on the fracture pattern and bone quality.
