This is a technical overview of an INVAMED device within the orthopedic & trauma solutions portfolio. Implant material choice, commonly medical-grade titanium alloys or stainless steel, influences strength, imaging behavior, and biocompatibility, and is considered alongside the fracture pattern. 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
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. Implant material choice, commonly medical-grade titanium alloys or stainless steel, influences strength, imaging behavior, and biocompatibility, and is considered alongside the fracture pattern.
CytroFIX Intramedullary Lengthening Nail (Magnetic): Overview
Magnetic intramedullary lengthening nail for limb-lengthening procedures in cases of congenital short stature, post-traumatic malunion, or nonunion with length deficits (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. Tibial nailing stabilizes tibial shaft and selected metaphyseal fractures with an intramedullary rod, allowing the bone to heal along a restored axis. 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.
- Implant material such as Ti-6Al-4V titanium affects strength, imaging behavior, and biocompatibility, and is weighed alongside the fracture.
- Fracture location and pattern strongly influence the choice among intramedullary nailing, plating, and screw fixation.
Frequently Asked Questions
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.
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.
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.
Clinical and Technical Context
Screw type, diameter, and length are selected by the surgeon according to the bone and the reduction being fixed. Whether external fixation or an arthroscopic approach is appropriate is a clinical decision made by the surgeon based on the injury and patient status. INVAMED's CytroFIX plate offering includes titanium locking and compression plates, such as the CytroFIX Distal Tibia Medial Plate for peri-articular tibial fractures. INVAMED's CytroFIX Intramedullary Tibia Nail features high-purity titanium construction with versatile proximal and distal locking options. The specific nail and locking strategy are chosen by the surgeon based on the fracture location and bone quality. 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. Joint reconstruction encompasses hip and knee prostheses and arthroscopy systems, extending the portfolio beyond acute fracture care into reconstructive surgery.
