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
Implant material choice, commonly medical-grade titanium alloys or stainless steel, influences strength, imaging behavior, and biocompatibility, and is considered alongside the fracture pattern. 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.
CytroFIX Intramedullary Tibia Nail: Overview
Intramedullary tibia nail by Cytronics (an INVAMED orthopedic division) designed to address a wide spectrum of tibial fractures - from proximal and mid-shaft to distal segments. Engineered from high-purity titanium, providing enhanced structural support, minimal soft tissue disruption, and versatile locking options accommodating both simple and complex fracture patterns (per invamed.com content surfaced via search index).

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. External fixators stabilize a fracture using pins or wires connected to an external frame, which can be useful in complex or contaminated injuries where internal fixation is not immediately appropriate. 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.
Key Considerations
- Nail diameter and length, plate contour, and screw configuration are selected to match the individual anatomy.
- All INVAMED orthopedic implants are intended for use by trained surgeons and in accordance with the IFU and applicable regulatory approvals.
- 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 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.
What about regulatory status and availability?
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
Clinical and Technical Context
Which implant and technique are appropriate depends on the fracture type, bone quality, and patient factors, and is determined by the treating orthopedic surgeon. Fracture location and pattern strongly influence the choice among intramedullary nailing, plating, and screw fixation. Nail diameter, length, and locking configuration are selected by the surgeon based on the fracture and the patient's anatomy. Whether external fixation or an arthroscopic approach is appropriate is a clinical decision made by the surgeon based on the injury and patient status.
